CELLULAR CONCEPT

MOBILE NETWORK

CELLULAR CONCEPT

Mobile network uses the concept of cell

A cell is the basic unit of the network

A cell depicts a mobile network wireless coverage

A cell is graphically hexagonal in shape

WHAT IS CELLULAR

RADIO

A term associated with wireless

communication signals

It is an electromagnetic wave

It uses electromagnetic energy

It is radiated from the source

It is transmitted by the antenna

It can take various patterns

All wireless communicating devices are

radio

CELLULAR TECHNOLOGIES

Mobile technologies has evolved the

years

When you think of technology think of

generation

Cellular mobile technologies are:

First generation 1G

Second generation 2G

Third generation 3G

Fourth generation 4G

Fifth generation 5G (emerging

generation)

PRE-PLANNING PROCESS

This involves collection of input requirements

Determining the demographic pattern of the area

Determining the terrain, and topographic pattern of the area

Performing theoretical coverage, and capacity plan

Performing traffic estimation

DIMENSIONING

Determines the technology of equipment

Determines the types equipment suitable for the network

according to collected requirement

Determines the type of network

It precedes network rollout

SITE SEARCH

This involves a team of some peopleThey perform the site look-out

Suitable for an appropriate location the equipment

More than one sites are foundThey are referred to as candidate sites

Page 9: HOW TO DESIGN A CELLULAR RADIO TECHNOLOGY NETWORK

SITE SELECTION

Primary candidate is selectedSelection is based on the input

requirements

Selected site must be free of obstructionIt must not be located on a too low and too

high terrain

Page 10: HOW TO DESIGN A CELLULAR RADIO TECHNOLOGY NETWORK

SITE SURVEY

This aspect involves a team technical body

known as TSS

The combination of site surveyors and RF

engineers

Determines the suitability for its intended

purpose

Performed based on the result of the

propagation model

Site survey is based on the land area
