Abstract-Through this paper we will discuss of wireless telecommunication systems. Compare

between this technology in many Feature and IEEE standards 802: light fidelity (Li-Fi) is a data

transmission technique which uses illumination or light -emitting diodes (LEDs) for sending the data.

Worldwide Interoperability for Micro wave Access (Wi-MAX) is a wireless communications

purposed to extend 30 to 40 Mb/s data rates, wireless fidelity(Wi-Fi) is a nearby area wireless

technology, that enables an electronic device to hook up to the internet using 2.4 GHz UHF and 5

GHz SHF radio station waves. Bluetooth is permits users to hook upcomputing and

telecommunication devices without private cables and ZigBee technology is the wireless that

everyday devices use to connect to one another.

Keywords:Wireless telecommunication, Li-Fi, Wi-Fi, Wi-Max, ZigBee, Bluetooth.

I. INTRODUCTION Cellular networking is an essential productivity tool for mobile workforce. With cellular networking,

we and our employees can stay linked to the company`s information resources nearly anytime,

everywhere Wireless networking is employed to meet many needs. May be the most frequent to

hookup laptop users who travel from position to another. Also use of wireless networking that .

These applications may include point-to-point communication, broadcasting, point-to-multipoint

communication, cellular system and other wireless sites, and so on [1].

The wireless local area network(LAN) can operate in the infrastructure method. This method lets you

connect wirelessly to cellular network devices within a fixed range and area of coverage. The gain

access to point has a number of antennas that allow you to interact with wireless nodes. In

infrastructure mode, the wireless access point changes airwave data into born Ethernet data [2],

acting as a bridge involving connected LAN and wireless clients. Connecting multiple access items

via a wired Ethernet, backbone can further expand the wireless network coverage. Like a mobile

computing device moves out from the range of one access points it moves into the selection of

another. As an effect wireless clients can widely roam in one access point domain to a different one

and still maintain seamless network interconnection [3].

II. LITERATURE REVIEW

Rahul R. Sharma et al. [4],[11] defined li-fi is transmits data using light emitting well suited for high

density wireless data than Wi-Fi , it has many application , It used in places that do not allow radio

frequency accessible like aircraft and hospitals and Internet anywhere, speed up to 1G . ATIS

Telecom Glossary, Brute [5],[6] talked about Wi-Max,this technology aims to provide a

telecommunications service over long distances and connectivity between multiple locations without

the use of cables, many applications use Wi-Max are mobile phones and service access to the

Internet's global network. And AkshitAggarwal,Swati Singh [7],[8]specifiedWi-Fi is transmit data by

RF as Data Transfer Medium, allows an electronic device to reciprocation data or hook up to the

internet using 2.4 GHz UHF and 5 GHz SHF radio waves.In [9] identified ZigBee is working for

long periods without the need for providing electrical energy between short periods, It does not need

a long time to start working. Using different frequencies as ranked in countries such as 902 MHz and

868 MHz and can be proceed in mesh (peer-to-peer) sites larger than is possible with Bluetooth. In

[10]defined Bluetooth is Radio communications designed to transmit data over short distances from

one meter to meter percent and consumption of small amounts of energy this technique is used

heavily in data transfer between mobile devices and in the peripheral accessories for PC.

IV. DISCUSSION After review all technologies, we found:

1. li-fi is transmits data using the spectrum of visible light, has achieved a new breakthrough, well

suited for high density wireless data than Wi-Fi, coverage range10m in bounded area andconfine

radio interference issues, free band that does not need license, It used in places that do not allow

radio frequency accessible like aircraft and hospitals and Internet anywhere, speed up to 1G [4].

2. Wi-Max, this technology aims to provide a telecommunications service over long distances and

connectivity between multiple locations without the use of cables [5]. More applications that use this

technology are mobile phones and service access to the Internet's global network and partnership in

the use of certain applications from more than one location. The expansion of this technology has led

to the evolution of digital phone technology IP Telephony, which depends mainly on the domestic

and international networks and connection lines T1 connections ,but is very costly than Wi-Fi[6] .

3. Wi-Fi is a local area wireless technology, which allows an electronic device to reciprocation data

or hook up to the internet using 2.4 GHz UHF and 5 GHz SHF radio waves. It depend on (IEEE)

802.11 standards. It is better for common wireless coverage within buildings [7], Point to point

Network Topology. It is transmit data by RF as Data Transfer Medium, was developed to be used for

mobile processing devices, such as clients, in LANs, but now increasingly used for further services,

including Internet and VoIP phone access, video gaming, and basic connectivity of consumer

electronics such as televisions and DVD [8].

4. ZigBee networking technology is working for long periods without the need for providing

electrical energy between short periods. Consume low power. As well as specially designed for uses

that need to provide a high degree of service, so there is a direct replacement in the event of a

hardware failure.Has a low data transfer This is enough to transfer the value of the sensors.It does

not need a long time to start working. Using different frequencies as ranked in countries such as 902

MHz and 868 MHzand can be proceed in mesh (peer-to-peer) sites larger than is possible with

Bluetooth. Compliant cellular devices are required to transmit 10-75 m, with regards to the RF

environment and electric power output consumption necessary for a given application, and turn on in

the unlicensed RF worldwide [9].

5. Wireless Bluetooth technology is Radio communications designed to transmit data over short

distances from one meter to meter percent and consumption of small amounts of energy this

technique is used heavily in data transfer between mobile devices and in the peripheral accessories

for PC. It Permits users to hook up a variety of computing and connection devices so easily, without

having to purchase additional or proprietary wires. It does not affect the barriers of the transmitter

[10].

V. CONCLUSION On this paper discussed wireless telecommunication technologies and each of these techniques (Li-

Fi,Wi-Max,Wi-Fi,ZigBee,Bluetooth) usefulnessdifferentiate to other. Some these techniques is

characterized in many features like speed, data rate, security and so on.
