Lenular Communication
A communication in which data is transmitted
through wireless broadcasting networks (cells)
is called cellular communication.
The term 'cellular' is derived from the word 'cell.
A cell is a basic geographic unit of a cellular
id communication system. Each cell consists of base
LA station, transmitter/receiver and antenna. These
cells cover different land areas to provide
coverage over a large area.

Answer:
Explanation: cellular network is an underlying technology for mobile phones, personal communication systems, wireless networking etc. The technology is developed for mobile radio telephone to replace high power transmitter/receiver systems. Cellular networks use lower power, shorter range and more transmitters for data transmission.
Wireless Cellular Systems solves the problem of spectral congestion and increases user capacity. The features of cellular systems are as follows −
Offer very high capacity in a limited spectrum.
Reuse of radio channel in different cells.
Enable a fixed number of channels to serve an arbitrarily large number of users by reusing the channel throughout the coverage region.
Communication is always between mobile and base station (not directly between mobiles).
Each cellular base station is allocated a group of radio channels within a small geographic area called a cell.
Neighboring cells are assigned different channel groups.
By limiting the coverage area to within the boundary of the cell, the channel groups may be reused to cover different cells.
Keep interference levels within tolerable limits.
Frequency reuse or frequency planning.
Organization of Wireless Cellular Network.
Cellular network is organized into multiple low power transmitters each 100w or less.
