The Mobile phone is two-way radio. When you are going to talk into a mobile phone it picks up your tone of voice and converts the sound to radio frequency power or radio impression, the radio impression travel through the atmosphere until they reach a receiver at a close by base location, the base location then sends your call through the phone network until it reach the person you are calling.

While you are received a call on your mobile cellphone. The message movements through the phone network until it reaches a base station close to your phone. The base station then sends out radio waves that are detect by a receiver in your telephone, wherever the signal are altered back into voice or records.

This is depending on the tools and machinist. The frequency that every operator utilize is whichever (1) 900 MHz (2)2100 MHz (3)1800MHz

The base stations are designed for a number of different purposes, such as to provide reporting to a broad area or to increase power in a heavily overcrowded area.

The base stations are divided into three cell.

1-The microcells this are use to develop the power of the main network, particularly in areas where the volume of calls is too high, such as in airports and shopping centers. They release less power than the microcells and have a collection of only a few hundred meters.

2-The microcells, this are the main configuration for mobile phone networks and work up to a theoretical 22-mile range, in reality they generally coat a much smaller area, probably as tiny as a mile or two, for the reason that the signal power is reduced by buildings, trees and features of the landscape.

3-Picocells, This are located in buildings and give devoted coverage and power to a very tiny area such as a particular floor in a building.
