Cellular Networks: An Underlying Technology for Mobile Phones, Communication System & Wireless Networking

Abstract

Cellular network is a fundamental technology for mobile phones, personal communication systems, wireless networking etc. This technology is developed for mobile phone to replace high power transmitter/receiver systems. It use very low power with a short range and higher rate of data transmission. Cellular network is arranged into multiple low power transmitters with less than of each 100w. The Cellular network offer very high capacity in a limited spectrum. It has the feature of reusability of radio channel in different cells. It also enables a fixed number of channels to serve an arbitrarily large number of users by reusing the channel throughout the coverage region. In cellular network, the communication is always between mobile and base station (not directly between mobiles).
