GSM Cells

Mobile phone cellular Network Structure is pretty much what makes up the basis of the GSM system. It has been set up to make sure that customers using their mobile devices are able to do so in the most manageable and efficient way possible. It deals with factors including communication set up, communication registration and the smooth transfer of uninterrupted coverage through the entire cellular Network Structure.

The Network Structure consists of four essential components: radio base stations serving the cellular network; a packet switched network responsible for coping with data coming from mobile devices; a core-circuit switched network which deals with text messages and voice calls; and the public switched network which allows mobile users to communicate with the wider telephone network.

Because there is a finite number of radio frequencies, and because systems other than mobile phone networks use them, the Network Structure requires that a cellular system is used to enable mobile phone companies to serve as many customers as possible without interference being a problem.

The Network Structure is therefore made up of a system of cells which do not function on the same frequency as the cell immediately next to them. However, this does allow for the repeated use of a particular frequency later on in the cell grid.

The range of a typical cell in a built up area is approximately half-a-mile. In more open areas the range of a cell can increase dramatically. In some places the range of a cell in the Network Structure can be as wide as 25 miles.
