DESIGNING A CELLULAR RADIO
TECHNOLOGY NETWORK
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
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
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
NETWORK PLANNING PROCESSES
