Question

Why cellular communication system is an efficient system for mass communications from the technical perspective?

(long answer please)

Answer 1

Answer to the question:

The cellular communication system uses small transmitters which are placed so as to provide best possible optimum coverage for mobile communication. If high power long range transmitters are used for communication, it will be interfered by the buildings and hilly areas. In cellular communication, towers are placed within number of cells, which comprises of relatively smaller area, require less power for transmission and provide good signals for communication. This also helps in reduction of interference and noise in communication. The cellular communication system also allows better use of frequency spectrum by allocating certain frequency range for different channels and not interfering in their transmission thereby giving it multi-channel and multi-user capabilities.
