Cell Phone Tower Leases
Mobile networks offer a number of advantages over other alternatives: increased capacity (service to many users simultaneously), low power consumption (for both individual devices and the base station), wider coverage and low interference. A simple example of a mobile network is a radio system for drivers of old taxis which were supported by multiple transceivers, each managed by a single operator who takes advantage of affordable cell phone tower leases.
In order to realize the mobile network, all base stations contribute directly to the radio signal that is divided into cells. The shape of the cells may be hexagon, a square, round or otherwise, the most common being the hexagon. Of each of these cells identify several operating frequencies (f1 – f6) of corresponding base stations. Same group of frequencies can be reused in other cells, provided that they are sufficiently remote, otherwise they create signal interference, which is undesirable.
