Recent and Previous Mobile Communication

From the year of 1983, the commercial application of AMPS (advanced mobile phone system) has enhanced the growth of the mobile communication system. The cellular concept was a great breakthrough.

Cellular Concept

The advent of cellular operation has developed exponential growth within the personal communication system involving different advancements such as wireless access, integrated circuits, digital signal processing, increased battery life, and so on. The cellular system acts by following the steps below.

An available frequency spectrum is separated into discrete channels to assign within groups to the geographic area where cellular service will cover.

The discrete channels have the capability to be reused within different cells ranging from 2 km. to 50 km.

An RF (radio frequency) transmitter is used within the service area when adjacent cells avoid interference by the operation on different frequencies.
