pcc wireless academic community

CHAPTER 1

INTRODUCTION

Purpose

Preface:

The adoption of wireless networking has grown very rapidly in the last

couple of years. There are many advantages to wireless networking, even

beyond the obvious lack of having to bend over your desk to plug in your

laptop. Many business and universities here in the Philippines are using

wireless to bridge two office buildings, to attract customers and to provide

easy-to-use network connectivity to roaming users for free.

Rationale:

Today, Wireless Local area Networks (WLAN) can be employed to

provide network connectivity almost anywhere. Consider the cost savings

from not having to run network cable to every possible location that could

have a computer or network device connected to it. Consider the

convenience of a wire-less enabled in campus. Imagine the increase in

accuracy of the school data entered directly into their notebook/laptop

PCC Academic Wireless Community 1

during his rounds through the WLAN instead of copying the lesson on the

white board. PCC community, down to every department, indoor and outdoor

public access areas are all suitable locations for WLANs. Free access to the

network, regardless of location, or traditional cable distance limitations is

one of the primary drivers for WLANs.

WLANs allow network in campus to no longer be constrained by the

100m distance limitation for copper cabling. Because WLANs use radio

frequency (RF) signals to communicate, users can stay connected to the

network almost anywhere.

Many schools are merging WLANs into their traditional wired network

to provide connectivity to the network to large numbers of users. School

campus rooms and departments are a great place to start considering

wireless in network. . A single antenna connected to a WLAN access point

(AP) can support many users.

The cost of photocopying of the lectures and presentations adds to the

budget of every student. By using WLANs, the need of paper for multiple

copies of the notes in the class can be eliminated

Information Technology Center don’t have any separate

system/network that can accommodate teacher and other faculty to upload


documents, although they have a domain

and server computer were in they shared some important files like installer

and updates of some application, still they don’t prioritized the uploading of

documents from the faculty. For the main objectives of the said department

is to give assistance to the students by means of providing appropriate

program and other services which the students needed in their curriculum.

And they believed that giving discussion to the students is part of the

teachers. The table below shows the problem statement matrix that shows

the problem of the current network of the ITC.

1.2 System Overview


Objective of the System / Study

This thesis study was looking forward on how to alleviate the concerns

of PCC community in curricular and extra-curricular involvement in the

school. Institutional Technology Center – Pasig Catholic College is suggested

in order that the purpose of the abovementioned ideas will be realized fully.

This thesis study is commenced to be able to:

1. Create an access point inside the school vicinity wherein all students

that have Wi-Fi devices can interact in the network anywhere in the

school premises.

2. Build wireless networks were in student can browse to the internet for

the academic used like researching and browsing some important

details about the topic discussed by their professor.

3. Provide shared folders in the new network (wireless network) and

allow teachers to upload documents such as presentation, topic

discussion and even assignment that the students needed in their

class.

4. Generate a paperless and multiple copy of the lectures which the

teachers uploaded without having a any cost.

5. upload important documents needed by the PCC community and allow

them to view or download from the network wirelessly, like:


CCNA modules for IM,IT and 4th year High School Students

Video Clips which always needed during program (National

Anthem, Alma Mater and the like)

Special announcements of school which addresses to the

students: like seminars, memorandum from office and schedule

of classes.

6. for the researchers, experience the actual steps in creating a network

based on the learning which we obtain during class.

EXISTING NETWORK OF PCC

At present, Pasig Catholic College have a Local Area Network where in

all computers are connected to one other and some printers are shared in

the office. Most of the laboratories and offices are already hook-up in the

network. Figure 1 show the current network at the 4th floor of Msgr. Gabriel


Building. The said network are maintained by the ITC technical support and

supervised by the department head.

The current network is composed of different servers; each server has

a function that assigned only for a specific task. These groups of server are

called the main distribution facility (MDF) for it distributes the different kind

of resources which are needed by the user. Listed below are the server name

and its function in the current network of Pasig Catholic College.


HP Server – the main offices that connected to this server are

registrar, finance, accounting, audit, HRD, institutional media center,

canteen and some of the grade school offices. This HP server is

contained with some program (created in visual fox pro) that currently

used by the registrar, accounting and canteen. The said offices are

connected to this server.

ISA Server – The main function of this server is to monitor the two

laboratories (403 and 404) that intended for browsing Cisco websites.

E-Mail Server - This server are intended for the website email of PCC

www.pasigcatholic.edu.ph. It holds all the email that enters to the

website.

Internet Server - All websites that can be browse by the laboratories

and offices are maintained and monitor by this server. Restriction of

the websites is done in this computer.

File Server – This is one of the most access servers in the network, for

it contains all the installer which installed in every computer like abode

Acrobat, Photoshop, Avira, NetOp etc.

Domain Controller Server - This server are intended for the local

network (domain) of the school. With this server, it can allow or not a

certain PC to connect to the internet by joining or joining it to the

computer settings of the PC.

General Nature of the System:

With the fast emerging of the new technology in our society nowadays,

almost of the offices and departments of the Pasig Catholic College are

shifting manual into computerized based program. With this project studies

the researcher will at least provide the preliminary structure of a new

wireless network for the PCC community.

This network will not only cater for the sharing of files of the faculty

teachers and uploading of documents for students and other non-teaching

personnel, but to provide also easy access on the network were in the


availability of the resources (lectures and topic discussion) can be easily

downloaded by the students so that they prepare to their subjects by having

an advance studies.

With this new network (to be hopefully executed) the researcher

believes that the Pasig Catholic College community will benefit a lot in terms

of:

Convenience: The wireless nature of this network allows users to

access network resources from nearly any convenient location within

their primary networking environment. With the increasing saturation

of laptop-style computers, this is particularly relevant.

Mobility: With this wireless networks, students can access the

resources even outside the classroom and laboratories.

Productivity: Users like students and teachers connected to a wireless

network can maintain a nearly constant affiliation with their desired

network as they move from place to place. For a business, this implies

that an employee/NTP can potentially be more productive as his or her

work can be accomplished from any convenient location.

Deployment: (For ITC department) Initial setup of an infrastructure-

based wireless network requires little more than a single access point.

Wired networks, on the other hand, have the additional cost and


http://en.wikipedia.org/wiki/Wireless_access_point

complexity of actual physical cables being run to numerous locations

(which can even be impossible for hard-to-reach locations within a

building).

Expandability: Wireless networks can serve a suddenly-increased

number of clients with the existing equipment. In a wired network,

additional clients would require additional wiring.

For the past four years in our stay in PCC, the researcher observed the

burdens of the students in carrying heavy loads of documents which consist

of copy of lectures and other presentations given by their respective

professors. With this thesis project, the era of paper documents will be

replace into more cost-efficient process of having this documents without

any paper to be carried. Moreover, the students the can reproduce it again it

again for this resources will be available always in the network. The easiness

to retrieve these documents from the network will be the advantage of the

stakeholders especially to students in a whole.

As mentioned above, this project study is designed to create a new

network (wireless) that will required to have a different devices to be able to

set-up this project. The proponents of the said project is suppose to use a

wireless router that will serves as the access point in the school area, the

usage of a set of Personal Computer that will serves as the main server of

the said network, and the devices (Laptop) that will connect to the network


and of course will be used by the stakeholders. The project group is trying to

use an application (Packet Tracer 4.11/3.2) which will be use for simulation

purposes, however this application were not a part of the designed network.

1.3 Document Overview:

Since Information Technology Center don’t have existing system that

cater this issue. Thereof this document contains a proposed project and the

probable result at the end of this study. This include on how the proposed

system/network will work according to the projected outcomes.

The ITC, being the in-charge department of this institution in terms of

new technology reserves the right to operate and implement this plot.

Although there is a set of rules in regulation stated by the researchers in this

document, the said department being an exclusive office that will implement

this project has the freedom to add more rules, guidelines and assert the

perimeter of the use of this network to those whoever become its

stakeholders. Once this project must accomplish it should be donated to the

school as their new facility that will be used by the students, teachers and

non-teaching personnel (NTP). The PCC community must be the beneficiary

of this hard-work research.

Further studies that may be needed to simplify this project are

welcome; on the other hand they must recognize the advocate of this


research study. Otherwise copying without any permission to the in charge

department will be strictly prohibited.

CHAPTER 2

OVERVIEW OF REQUIRED WORK

Proposed Enhancement

The improvement of information technology in our society today

serves as an important role in changing the lifestyle of the students,

especially in Pasig Catholic College. With this new high-tech devices and

resources (internet) which these students have, they can easily manage their

studies. Nowadays, majority of the student are very dependent to the

internet, an easy access to the network are the big advantage of those who

knows how to maximize this resources. Every assignment and project which

the teacher gives is only a one click for them. Browsing to the internet and

copying the needed files and answers are normal for them even without

recognizing the source page were in they get the answer.

The researchers are also aware with this kind of system which the

other students do. With that, the proponents of the project established a plan

to create a new network were in the main requirements (devices use by the

student) for this project are present this institution.

--------------------------Build Requirements---------------------------

PCC Academic Wireless Community – Pasig Catholic College 18

2.1.1 Allocated System Requirements

We can’t deny the fact that ITC department serves as one of the

important office in this institution, for it served a delicate responsibility in

maintaining the school facilities especially to the computers and other

devices related to information technology. The said department also

maintains the computers in every office of the institution like the grade

school office, high school faculty, college faculty and others.

The current network of the ITC is composed of different server, the

fileserver, domain, stratholme and hp server. With this network, inter-office

can communicate and send documents to other offices however they must

currently connected to the network (wired). The current network of ITC was

using a static (not DHCP) IP addressing which means the IP address of each

computer that connected to the network are manually assigned by the

computer technician. In this project study the researcher recognize that

using static IP addressing can generate a problem in the network by means

of duplication of IP address that sometimes causes to the malfunction of the

connection to the domain. With this scenario the researcher gets an idea to

create a new network (wireless network) that will eliminate this kind of

dilemma/problem and provide an access to the network even not currently a

member of the domain group. With the proposed project of the group, it


allows the students to inter-act to the network wirelessly provided they have

a laptop. With the said proposed project, student will be benefited more on

the way that they must know how to maximize the said network.

In researcher’s observation, the more the hard copy of lectures of the

students, the lessen the time they read it. Unlike if the lectures are in the

network, they will not worry anymore the bringing of their notes and they

can focus to their study in the classroom. That’s why this project study are

focusing to the improvement of the study habit of the student.

With all the good criterion of this project, we can’t stay away from the risks

that may happen to this proposed new network. We all know that in our

current time many students of Pasig Catholic College have a well verse

knowledge in computer technology, were in they can hack and destruct files

of the others, this security issue are very common in all network using a

wireless connection. Enable to avoid this risk the researcher of this project

will supply a safekeeping measures to the proposed network by creating a

security password by means of WEP and WAP a security measure used by

wireless network.

Possible stakeholders can use this network provided they ask must follow the

rules and guidelines set by the ITC and the researcher upon using the

wireless network.

2.1.2 Proposed Enhancements


For this project, the uses of network devices and its location are the

concerns on how to enhance its efficiency and reliability:

To use a more recognized brand of device especially in choosing a wireless

router.

The position of device (router) inside the school vicinity, it must be located to

the center part the building to be able to distribute the signal evenly.

The researchers plan to put a device in every two floor of the building to

supply more signal in the whole campus.

An open area can create much more radio frequency compare to the inside

of building.

With this researched, the proponent’s aims to work out the following purpose

upon building this project and hopefully implement in the future.

Set-up a wireless based network inside the vicinity of Pasig Catholic

College that will be monitor by the ITC department -technical support.

Generate a paperless document for the student.

Create a shared folder were in all lectures and presentations of the

teacher will be upload, and access by the students.

Upload the important files that needed by the student in their study

and can be easily access. Just like CCNA modules for computer related

courses.


Open any possible recommendation for different offices for the

improvement the said network.

System Trouble Report

In spite of careful planning on how to make the network run in normal

process, still error and malfunction will almost be part of the network upon

implementation in the future. Whenever users will encounter any problem in

the connection or in transferring file they may:

Ask assistance to the ITC technical staff for they have a more

understanding about this thing.

Refer to the users manual which created by the researcher and look for

the possible error and solutions.

Check the personal devices; somehow it is the wrong way of using the

device (laptop) that causes malfunction.

To avoid destructive files like viruses, the personal device must consist

of anti-virus and updated every week.

If cannot connect to the network, go closer near to the access point,

distance can affect the signal receive by your device.

Unable to copy or download files, check the connection of your device

if it is really connected to the network.


2.1.3 Scope and Limitations

Scope of the Proposed System

This project study aims to benefit PCC community (PCC Community include

teacher, students, and NTP) in terms of file sharing, availability of documents

on the network and internet browsing (additional benefits). Possible

beneficiaries that will benefits this project study are the following:

Limitation

This proposed network must be clearly stated to its stakeholders that

its main purpose in this institution is to only connect users through a one

network, were in each user can benefit in different ways; and “not” to create

a new connection in the network and provide an internet connection.

However possible revision in this project study like allowing internet

browsing are all depends on the plan of the department head.

The final set-up of the network will be the last phase of this project

after its testing, and the in-charge department (ITC) will maintain the said

network.

Direct and Indirect User


The following are the possible user that may use this wireless network

(WLAN), teachers, NTP and students can be classified as the direct users for

they are the one who will access this network. And the

Indirect user is the technical support that assigned to maintain the wireless

network (WLAN), the researchers considered the technician as indirect user

because their only rule is to monitor and maintain the said network.

TEACHERS / FACULTY:

Teachers can upload their lectures and presentation in the network to

allow their students to study in advance. Teachers can also leave assignment

and sit work to their students by uploading it to the network, that even she’s

not around her student has a productive output.

STUDENTS:

The availability of lectures are always present in the network, so they

don’t need to worry about photocopying of this lectures.

Students can also study in advance to their subject. Students may eliminate

the bulkiness of paper in their bags. For computer related course, especially

in Cisco subject; they can browse their modules anywhere in the school

vicinity were in convenient for them to study.

NON-TEACHING-PERSONNEL


For non-teaching personnel, they may download files which they are

needed even without going to ITC, provided file was uploaded and being

shared.

On the whole scope of the project; the integration of modern

technology and academic (study) are the main concern of the researchers.

Improving the study habit of students that even outside the classroom they

can browse their lesson without any documents (include the hard-copy of

lectures) to be carry all the time.

TECHNIAN / TECHNICAL SUPPORT

The technician are the one who maintain the wireless network, they

may allow or prevent the none registered MAC address on their office.

2.2 Deliverables

The subject System Analysis and Design and Project Management which is

instructed by Mrs. Wilma de Pano serves as our directives upon creating this

researched study.

Milestones 1 – 10 give us an idea on how to create documentation to

the project that we were developing. Below are the simple explanations on

the milestone that we created.


Milestone 1 – Project Proposal

Formal requisition of permission from the organization for the conduct

of the study and approval of the project.

Milestone 2 – Project Scope

Gain an understanding of the size and scope of the system by means

of interview to the department which you choose to develop a new system,

proving if the said project is worth to be developed. Stated here also the

problem statement matrix and the opportunities /directives that triggered

the said project.

Milestone 3 – System Objectives and Constraints Matrix

A thorough understanding of the problems, opportunities, and/or

directives that triggered the project.

Milestone 4 – Context and Decomposition Diagrams

In this stage data flow diagram and other process modeling are

created. But in our case since we are not developing a system, we come-up

with an architectural design in our project.

Milestone 5 – Data Modeling


The entity relationship diagram (ERD) for the system being developed

including a brief narrative to walk a non-computer-oriented reader through

the key-based ERD.

Milestone 6 – Process Modeling

In this chapter, constructing an event list, decomposition diagram, event

data flow diagram, system diagram and primitive diagram are being created

together with the narrative statement on non-computer-oriented user.

Milestone 7 – Data Analysis

Normalize that ERD hat first developed in Milestone 4 and the

synchronization of process and data models through a Data to Process CRUD

matrix.

Milestone 8 – System Proposal and Process Analysis and Design

Preparing a system proposal with a recommendation of a candidate

solution you propose and alternative solutions, including the identification of

the person-machine boundary and design units.

Milestone 9 – Input and Output Design


Design a computer generates inputs and outputs of the system like

forms, queries, reports and others. But we think we will not do it in our

project.

Milestone 10 – User Interface Design

Milestone 10 stated that we must design of a user-friendly terminal

dialogue that will help users get to the on-line outputs and inputs of the

project, but in our case will set-upping a network that will serve as our

project protocol.

All the deliverable the we use will be created in a Microsoft Word (word

processing application), Microsoft Visio and EDraw Soft Diagrammer 3

(Architectural design making), and probably for an instance we will be using

a Packet Tracer 4.11 / 3.2 (for simulation purposes).Microsoft Project will be

also useful in creating our Gantt Chart and WBS (schedule )

2.3 Reusable software and Off-the-Shelf Products

All of the document that will be created will be based on the following

application stated above. Creating a milestones and section are all word

based application while constructing a Gantt chart and WBS were both be

done in Microsoft project. Although there are application that can support

every activity, just like instead of using Microsoft word in creating an


architectural diagram the researcher can do it Microsoft Visio to ease that

activity. But in simulation process only a Packet Tracer can support that

activity.

2.5.1 Constraints

Time

By the period given used for the conceptualization of the said project,

it will take at least one whole semester before its testing and possible

implementation. Being direct by the basics and previous requirements of its

completion, the promoter of this project is continuously seeking the best and

easiest possible means to realize this attempt in the soonest possible time.

Still, it is assumed, for fairness sake, that the prototype will be finished in 6

months or less

Methodology

There are many preparation and tools which are needed in this project

study; the group has planned to use different kinds of methods upon


developing this project study. Proceeding in Milestone 2, the methods that

we will be using are business case, problem statement matrix and WBS.

Since this project study is not a system we will not be using any diagram like

the data flow diagram, context diagram and class diagram otherwise we will

use an architectural design by the use of Microsoft Visio for our project study

and a Packet Tracer 4.11 for our simulation purposes. We will be using also

work breakdown structure (WBS), Gantt chart and Pert chart for our

milestone monitoring.

Restrictions:

Before the first execution of this project study, the said network must

consist of various guidelines which will be followed by its stakeholders.

It is clearly stated that the main role of the students in this project was

to view and download only files from the network. Any other actions that

they may do are not allowed by the in-charge department. For teacher,

uploading of files as well as downloading was there main function in this

system. Other employee (NTP) can access also directly to the network to

download and upload files.

All the roles stated above by different stakeholders can be possible on

the other hand they are registered on the ITC department. Password is also

needed before accessing to the wireless network.


Controls:

Upon connecting to the internet wirelessly, the user’s wi-fi device will

ask a password in order to join the web, if the user’s device is not yet

registered to the ITC office he cannot access the network, otherwise he/she

must go to the office to register his device and ask the login password. The

security protocol of the device was configured on its system by the used of

WPA2( personal + AES and fill out '1234567890abc'). With this kind of

process only registered laptop can only connect to network and at the same

time to the internet.


CHAPTER 3

System Architecture

3.1 Hardware

In this proposed network , all the system hardware that will be use in this

project are very relevance to the group, for it is the main requirements of our

project to be able to create a new network. With the following hardware

stated below, we believe that this project study will be possible and may be

implemented as soon as it may bear out to be feasible.

WIRELESS ROUTER

Enable to create a WLAN, wireless router is the first device to be

consider. For it will serves as an access point in an area was in all data

communication happen during transferring file. The project team decided to


use a Linksys WRT54G2 Wireless G Router in creating the last phase of this

project milestone. (Currently used by the researcher on their testing)

But due to the financial constraints of the group they have decided to

use the Linksys WRT54G2 Wireless-G Broadband Router for their

demonstration basis for it also reach almost 3/4 of the required specification

which wireless router N have. But the project group highly recommends to

the ITC department to use a wireless router N technology for it has a high

advantage to compare to G-Technology.

Below are the characteristics and specification of wireless router N-

technology which the project group recommends to the ITC department,

enable to achieve their plan in their proposed network.

WIRELESS ROUTER N-TECHNOLOGY

The Access Point built into the Router uses a dual-band version of the

very latest wireless networking technology, Wireless-N (draft 802.11n). By

overlaying the signals of multiple radios for each band, Wireless-N's "Multiple

In, Multiple Out" (MIMO) technology multiplies the effective data rate. Unlike

ordinary wireless networking technologies that are confused by signal

reflections, MIMO actually uses these reflections to increase the range and


reduce "dead spots" in the wireless coverage area. The robust signals travel

farther, maintaining wireless connections much farther than standard

Wireless-G.

With Wireless-N, the farther away you are, the more speed advantage you

get. It works great with standard Wireless-G, -A, and -B equipment, but when

both ends of the wireless link are Wireless-N, the router can increase the

throughput even more by using twice as much radio band, yielding speeds

much faster than standard Wireless-G. But unlike other speed-enhanced

technologies, Wireless-N can dynamically enable this double-speed mode for

Wireless-N devices, while still connecting to other wireless devices at their

respective fastest speeds. In congested areas, the "good neighbor" mode

ensures that the Router checks for other wireless devices in the area before

gobbling up the radio band.

Since the Router can operate in both the 2.4 and 5 gigahertz radio

bands at the same time, it effectively doubles your available wireless

bandwidth. For instance, you could

set up your network to handle video streaming on one radio band, and use

the other band for simultaneous data transfer--avoiding any interference or

collisions that would degrade the video performance.

To help protect your data and privacy, the Router can encode all wireless

transmissions with industrial-strength 256-bit encryption. It can serve as your network's

DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and


most known Internet attacks, and supports VPN pass-through. Configuration is a snap

with the web browser-based configuration utility.

Device Description

The sleek Simultaneous Dual-N Band WRT610N Router sets a new

standard for design, expanded bandwidth, and robust performance. It's the

ideal router for all your current and future digital entertainment needs.

Introducing Linksys EasyLink Advisor (LELA), the application that provides

and easy way to setup, view, manage, and repair your network - it's like

having a Linksys expert in your home helping you to get the most out of your

home network! Install it, set it up, and let it work for you! Linksys EasyLink

Advisor works in the background, watching over your network. It will alert

you to new devices, potential problems, security breaches and updates. If a

problem occurs LELA steps in with a wizard to guide you and solve problems

fast. It's so advanced, it's simple!


Illustration 1: Propose Router to the ITC Department

PERSONAL COMPUTER (server)

WLAN can still operate even without a server pc connected to it.

But in this project the researcher designed a server based PC in this wireless

network for it will serve as the fileserver or storage of all documents that the

teachers may uploaded. This PC will be also used in configuring the router in

the network.

The specifications of this server PC are the following:

• Intel® Core ™ 2 CPU

• Processor E3110 (2.13 GHz)

• 1333MHz FSB with 6MB L2 Cache

• Powered by Intel® Xeon® ProcessorA

• Microsoft Windows XP Service Pack 2

• 1 GB memory

• 80-160 GB (hard disk).

LAPTOP (USER’S DEVICE)

This is normally needed by the stakeholders to enable them to

access and use the proposed network. Laptop must be a Wi-Fi ready. And


even the laptop is not a Wi-Fi ready it can be also use by means of using

an USB Wi-Fi or USB antenna that currently present in market.

Other user’s device that can be use to access wireless network are

PDA, cell phone, MP3/4 and even desktop as long as it can detect wireless

signals.

USB Wi-Fi

This kind of device is attached to a laptop or desktop that wants to

connect to the internet wirelessly; this could be an optional choice of the

user.

PRINTER SERVER

Since the ITC has this device the researches plan to connect it to their

network, but it is only an add-ons in the said network, basically the proposed

network is capable of installing printer in its system, but the researcher

didn’t focus on it.


3.2 Data Communication

In this project, data communicate through a network wirelessly.

Students and teachers can communicate to the network by means of

uploading and downloading of files.

Show below is the possible set-up in the proposed network of the team.

Figure 6: Proposed Set-up of the Network


The set-up shown in Figure 1 is only a visualization of our proposed

project; server pc and wireless router must be connected through a wire

cable (straight through cable), and the devices (laptop, PDA and cell phone)

are/can connect/ed to the access point wirelessly. A firewall is also needed

in order to lessen and/or avoid the malicious hacker that will try to hack the

network.

Addition of output devices (figure 7) such as printer can be done

on the time that this project was implemented and tested.


3.3 Software

The following software needed in project are as follow:

MS OFFICE

Basically this is the first software that we will be using by the group

enable us to create our document plan our schedule and designing our

network. MSOffice includes word, visio, project and even ms paint.

PACKET TRACER

This is a simulation program that can simulate any network connection

that we could possibly imagine. This is a program designed by CISCO

systems. The said software is so powerful we can create real time checking

of what will happen if a packet is sent from one end to another. By using this

we can simulate the design and decide on which scenario or setup is best for

our system.

3.4 Architectural Diagram


Figure 1.2 shows the actual set-up of the project inside the vicinity of

PCC. As we observe every building was consist of 1 or 2 router (Linksys

WRGT54G wireless router G), definitely building consist of 2 access point are

the area were in frequently visited by the students like library, canteen and

classroom that are use by the students in their study, earlier before the

researcher stated that downloading of files are the main role of students in

this project and it will be used in academic/study matter. In order to cover

all the area with Wi-Fi signals the researcher plan to allocate an access point

in every building with corresponding usage. 1 access point in an area is used

for sharing of files inter-office as well as uploading. Mean while 2 access

point in the building were used by the students.

The four routers that was mentioned above are located in the three-

faculty room of the school ; the college, high school, and grade school faculty

office respectively and the other one is put on the ITC office. This are the

places choose by the researchers because of the result that they gather from

their survey that shows the number of the students visiting the library

especially high school and college, and to the computer laboratory in fourth

floor.

Notice that even though the researcher set-up their wireless router on the

ITC and on the college faculty office still the researcher mentioned that


library is frequently visited by the students. It is because library is located in

between the college faculty and ITC, therefore Wi-Fi signals can be feel on

that area.

Another reason why the researcher choose this area it is because,

most of the teachers are downloading files and document in the internet that

they uses for their topic discussion, therefore they need not to go to ITC just

to connect to the internet and download files.

CHAPTER 4

Wireless LAN Implementation

4.1 Equipment Procurement

Wi-Fi Services can provide all of the procurement activities and

tracking for all WLAN components and miscellaneous equipment

requirements as detailed in the WLAN Design.

Enable to implement this facility more successful all the devices

needed in this network must follow the required criteria.

Laptop must be a Wi-Fi ready (802.11 a,b,g standard);

USB Wi-Fi can be use as signal detector if laptop has no built-in

Wi-Fi

PC that will be use as storage of file and monitoring with

internet firewall

4.2 Network Connectivity Provision


All Wi-Fi users that want to connect to the wireless network must

have the network connectivity provision to the ITC department in order them

to browse and access the internet and share files to their

co-workers/students. User can get this provision by registering their laptop to

the said department; by doing this, they may undergo concise orientation on

how to use the said facility (wireless network) properly and beneficially to

their part. They will be given also the rules and regulation of using Wi-Fi that

the researchers formulated.

Authentication

Establishing a user's identity is the first step to controlling access to

network resources. The ITC department will authenticate users by validating

their media access control (MAC) address on the time that the user

registered their device to the department. By means of this process they can

monitor who the users are connecting to the network.

4.3 Rules and Regulations:


http://searchnetworking.techtarget.com/sDefinition/0,290660,sid7_gci212506,00.html?int=off

Whoever student/s wants to use Wi-Fi technology must register first

his/her Wi-Fi devices to the ITC office.

The ITC personnel are only allowed to put a password whenever their

device asks them to input it.

Every user must undergo brief orientation on how to use Wi-Fi

technology properly and valuably.

Wi-Fi user especially students must NOT browse any pornographic sites

and other sites which are not part of academics study, otherwise if

he/she may be caught browsing the restricted sites he/she will NOT be

given again any privilege to access wireless network.

File sharing is allowed unless files and documents that are shared are

not violating the moral values.

Faculty are only allowed to upload lectures to the network and

students are not.

The ITC technician will assign the computer name for all laptop that

wants to be registered, and users are not allowed to change it even

though it is there personal device. For it is the only way that the

technician can monitor their device.

Guidelines for Uploading Documents (for teachers)


1. Teachers that already registered their laptop to the ITC office are

only allowed to upload files.

2. Assigning password to the documents/presentation are essential,

in order to prevent other students to view it. With this matter

teachers can ask assistance to the ITC staff in inputting password

to their documents.

3. Announcement and notice are also allowed.

4. Private message that striking someone is strictly prohibited.

4.4 Installation

The wireless network installation will be completely done after this

project will be decided to implement by the department head. But for a while

the researcher already installed 1 access point located inside the ITC

department. The said access point where place near the window in order to

broadcast high signal to the ground. Actually, with the experiment done by

the researcher the accounting department can detect Wi-Fi signals outside

their office that result them to freely access to the internet sometimes.

Installing the wireless router is not as simple as anyone think, for it

requires knowledge on networking and analyzing the best place on where

the device will be place. Basically upon installing the device you must know

how far its signal reaches (thick walls and ceiling can affect the performance


of its signal) so that you can mark the area which has a strong and weak Wi-

Fi signal (hotspot are). You must also identify who are the users that will use

this network and what are their purposes.

For example, the researchers set that the main role of the students is

to download files which their teachers uploaded and they can browse the

internet in addition. While the teacher are allowed to upload document and

lectures they can also browse and download files.

4.5 Maintenance

Implementing a WLAN is straightforward, but making sure it runs

optimally can be challenging. Luckily, the researchers and ITC technician can

control and maintain the wireless network by using well-known

methodologies based on the OSI model.

Just like, enabling the media access control address filtering or MAC

Address Filtering, a special feature of Linksys WRT54G2 Wireless G Router

were in it can allow or prevent the user to access the network by means of

blocking their MAC address. With this kind of method the technician in-

charge in WLAN can maintain and troubleshoot the network at ease. In

monitoring the MAC address of the user the researcher recommends to the


department to make a simple database which will be use for storing the

media access control address of WLAN users.

In addition, the researcher installed that latest monitoring kit of the

WRT54G2 Router, the Linksys – Easy Link Advisor (LELA). This type of

program can detect the entire wireless devices that are recently connected

to your router. With this, monitoring will be easy to the technician who

maintains the network.

Sample screen shot of LELA.


Illustration 2: LELA

The researcher will use the Wi-Fi Protected Access (WPA) feature of

wireless G-router instead of Wired Equivalent Privacy (WEP) in its security

phase, because the researcher recently known that WEP are easily decrypted

by the Wi-Fi hackers although there are no cases of hacking in the school

campus reported. But still the researcher wants to provide and implement a

secure and hacker free wireless LAN inside the


PCC campus. WPA2 is an advance feature of wireless router security that

cannot be easily convert/decrypt by any one.

4.6 Overview

This thesis study was being organized and planed accordingly, due to

the fast emerging of the technology in our society nowadays. With thesis

proposal, the researcher believes that Pasig Catholic College can create a

generation Y students (generation Y means person who can easily adopt the

change of technology and know how to maximize its resources beneficial to

his/her part) that soon to be a generation Y employees also. This project

study also aims to prepared the school and its student to the new generation

of learning were in computers and laptop are dominant use for teaching that

will be call school of the 21st century.

This proposal will introduce the Wi-Fi technology in the whole PCC

community and ads to the 1st class facility of the school were in it can attract

other students from different school to enroll in PCC. PCC will become a Wi-

Fi campus just like other big universities and colleges here in metro manila.

4.7 Recommendation


All students and faculty that wants to used the WLAN connection

are required to registered first their device (laptop) to the ITC department in

order to get their MAC address and recognized their device whenever they

will connect to the said network. With these, the researcher wants to

recommend a have a registration fee upon registering their device. So that

not only teachers and students will be benefited to this facility, on the other

hand the school will get a profit to this facility and retrieve their investment

to the device that they buy (wireless-router). With this idea the researchers

believes that the return of investment (ROI) will get in a 1 semester only.

It is on the part of the school on how much they will charge to those

who want to avail this facility.

CHAPTER 5


WLAN Schematic Diagram

5.1 Schematic Diagram

Diagram 1: Schematic Diagram of Proposed Network

The diagram shows how the wireless LAN is being set-up inside the

school premise. In the schematic diagram shown above, the ISP will give a


public IP to the department (ITC), that public IP will be distributed to the four

wireless routers through the switch. The public IP will be used as the static IP

address of each router to enable the internet, but the configuration of the

router to network the Wi-Fi devices will be using a dynamic host

configuration protocol (DHCP).

Each access point (AC) has corresponding users to avoid traffic in the

network, for example: AC point of Grade School – only teachers and non

teaching personnel of grade school department are allowed to access to that

router, provided that they have a network connectivity provision. And same

to other access point, its label is equivalent to those who are allowed to

access on that device. On the other hand AC located inside the ITC which

label wrt54g2 is the access point allocated for students, it has a server pc

that will be used as the storage medium in order to save the files and

documents that the teacher wants to upload, and later downloaded by the

students.


Diagram 2: Simplified WLAN

The diagram show how the Wi-Fi devices connect to the WLAN, once

the wireless router has been configure and you have the network

connectivity provision, you can easily connect to the network and do

researching of downloading files.

Diagram 1: Set-up of the wireless router located at the fourth floor (ITC) of the Bishop San Diego building

The table shows the signal receives by the device (laptop) to the

different area of the school. Wall and flooring affects the signal more, radio

frequency signal cannot pass-through a thick wall especially in the flooring.

Note that the size thickness of the flooring is approximately 2 feet while the

walls are 7 inches (estimated only).

Diagram 2: Set-up of the wireless router located at the second floor (college faculty) of the Bishop San Diego

building


Diagram 3: Set-up of the wireless router located at the second floor (high school faculty) of the Msgr. Sunga


As of now are there is no testing done in this area for there are some

factors to be considered. But the real position of this router in the building

are located outside the high school faculty room. The researcher decides to

put it there in order to broadcast signal to the near offices just CCF, EVP and

other neighboring offices.

Diagram4: Set-up of the wireless router located at the ground floor of the Fr. Urbano building.


The experiment done by the researcher results them to gather the

information/data displays above. With data shown above, the ITC

department and the Wireless LAN users will be aware on which parts of the

school have the high radio frequency signal (hot spot) and which place

cannot receive signal (dead spot). Signal receive by the device will differ on

its location, just like when the user are inside the classroom and there is no

opening they will receive less of signal compare to those who are in the open

field. The result of the experiment and tally above are base on outside

testing (outside the room, near Corregidor).


Statistics shown are base on the actual measuring of the distance and

RF signal that are being receive by the laptop used by the researchers. Note

that the wireless router that is being used in this phase was the Linksys

WRT54G2 Wireless Router-G and NOT the proposed router which the

researcher recommends to the department (Linksys Dual-N Band WRT610N

Router). So whenever this project study were implemented and the

department will decide to used WRT610N Router, the data on the table will

change especially the radio frequency received by the users device in

different location inside the school.

5.2 User’s Manual


Wireless local area networks (WLAN) are easy to operate as long as

know how to use a laptop/desktop. First to bear in mind on using a wireless

network is what you will do to that network, will you browse the Internet,

download files or upload lectures. You must have a direct plan when using

the WLAN because always remembers that the bandwidth that our school

paid to the ISP was being wasted if you don’t know how to use it sensibly

that sometimes causes traffic to the network. Anyone who wants to use this

facility must have a wireless laptop and the network connectivity provision

from the ITC, this two requirements are only way to make use of this project.

Connecting to the WLAN

User must find the wireless LAN symbol on his/her laptop (lower-right

part of the screen, near the system clock), once you find it right click and

select scan for WLANs, your device will pop-up a message box display all

the current WLAN near to your location (just shown below).


The only thing that you will do is to choose where WLAN do you want you

connect, but basically in this project the researchers set a WLAN for each

user (student, faculty of different department). After you decided where you

want to connect another message box will appear that requiring you to put

the network security key or the passphrase for you to completely join the

wireless network. (The default passphrase of the WLAN is morimoswat) Just

like shown below


Always remember that each WLAN has a different network security key

and every month this key are being replace by the technician who maintains

the said network for security reason. After you have inputted all necessary

requisite you are now connected to the WLAN. You can now browse the

internet and download your lectures at your steady place (as long as you can

receive RF signal to your place).


The researcher always tells that “students can download files and

lectures which their teacher uploaded” but the question is how to do that.

First step is go to windows start-up and click run.


Next is, while you are in the run attribute type the computer name that you

want to access, for example our server pc has a computer name of itc19.

But before typing the computer name don’t forget the double back slash ( //

) .

After doing that wait for 10-20 second to partially connect to the computer

that you are accessing, once there is a dialog box that asking for username

and password supply it, basically that username and password of the

computer that you are accessing are the one you need to input to the dialog

box and then click OK.

Just like shown below.


The time that your laptop displays the shared folders of the computer (via

wireless) you can now download the files that your needed.

By default the researcher used the itc19 (computer name) computer

to serve as our server pc. The picture shown above is the actual screen shot

of our wireless network.


The folders above are shared files of the itc19; each folder contains

different presentation and lectures of the certain subject respectively. In this

part student can easily copy this file and save it to his desktop. Always

remember that this shared files are allow only for student to copy or

download it. Student cannot add any files to this computer unless they will

go the ITC and request for uploading files. No one also are allowed to delete

this files, even they try to delete files it will not work for there is a security

setting that change by the researcher.


Shown above is the copying of files to the itc19 and saving/pasting it to

desktop of the WLAN user.


5.3 Router Configuration

Access the Web-Based Utility

To access the web-based utility, launch the web browser on your computer,

and enter the Router’s default IP address, 192.168.1.1, in the Address field.

Then, press Enter. A password request screen will appear. (Non-Windows XP

users will see a similar screen.) Leave the User name field blank. The first

time you open the Web-based utility, use the default password admin. (You

can set a new password

from the Administration tab’s Management screen.) Click OK to continue.

Basic Setup


The first screen that appears is the Basic Setup screen. This allows you

to change the Router’s general settings.

In this page you can change the default setting of your router and assign

unique password and service set identifier (SSID) for your router.

Basic Wireless Settings


The basic settings for wireless networking are set on this screen.

There are two ways to configure the Router’s wireless network(s),

manual and Wi-Fi Protected Setup. Wi-Fi Protected Setup is a feature that

makes it easy to set up your wireless network. If you have client devices,

such as wireless adapters, that support Wi-Fi Protected Setup, then you can

use Wi-Fi Protected Setup.

Wireless Configuration To manually configure your wireless

network, select Manual. Proceed to the “Basic Wireless Settings”

section. To use Wi-Fi Protected Setup, select Wi-Fi Protected Setup.

Proceed to the “Wi-Fi Protected Setup” section.


Wireless Network Mode From this drop-down menu, you can select

the wireless standards running on your network. If you have Wireless-G

and Wireless-B devices in your network, keep the default setting,

Mixed. If you have only Wireless-G devices, select Wireless-G Only.

If you have only Wireless-B devices, select Wireless-B Only. If you do

not have any wireless devices in your network, select Disabled.

Wireless Network Name (SSID) The SSID is the network name

shared among all points in a wireless network. The SSID must be

identical for all devices in the wireless network. It is case-sensitive and

must not exceed 32 characters (use any of the characters on the

keyboard). Make sure this setting is the same for all points in your

wireless network. For added security, you should change the default

SSID (PCC Academic Wireless Community) to a unique name.

5.4 Network Troubleshooting


In spite of careful planning on how to make the network run in normal

process, still error and malfunction will almost be part of the network upon

implementation in the future. Whenever users will encounter any problem in

the connection or in transferring file they may:

Ask assistance to the ITC technical staff for they have a more

understanding about this thing.

Refer to the users manual which created by the researcher and look for

the possible error and solutions.

Check the personal devices; somehow it is the wrong way of using the

device (laptop) that causes malfunction.

To avoid destructive files like viruses, the personal device must consist

of anti-virus and updated every week.

If cannot connect to the network, go closer near to the access point,

distance can affect the signal receive by your device.

Unable to copy or download files, check the connection of your device

if it is really connected to the network.

Possible Error


Error: Your computer cannot connect to the Internet.

Solution: Follow these instructions until your computer can connect to the

Internet:

• Make sure that the Router is powered on. The Power LED should be

green and not flashing.

• If the Power LED is flashing, then power off all of your network devices,

including the modem, Router, and computers. Then power on each

device in the following order:

1. Cable or DSL modem

2. Router

3. Computer

• Check the cable connections. The computer should be connected to one

of the ports numbered 1-4 on the Router, and the modem must be

connected to the Internet port on the Router.

Error: Your computer cannot access the server pc.

Solution:


Check if you correctly type the computer name of the pc you want to

access.

Verify your connection status, are sure that you are connecting to the

right WLAN.

Check signal status, maybe your out of the hotspot.

Error: No Signal Receive.

Solution:

Make sure that your device (laptop) is working properly

Check USB Wi-Fi maybe its loosen (for non Wi-Fi ready laptop)

Go closer to the hot spot (open grounds)

Wireless Disclaimer

The maximum performance for wireless is derived from IEEE Standard

802.11 specifications. Actual performance can vary, including lower wireless

network capacity, data throughput rate, range and coverage. Performance

depends on many factors, conditions and variables,

including distance from the access point, volume of network traffic, building

materials and construction, operating system used, mix of wireless products

used, interference and other adverse conditions.
