The WHOLE of the geographical area is divided into HEXAGONAL shape geometrical area called cell and each cell having its own transceiver. Each BTS (cell site) ALLOCATED different band of frequency or different channel. Each BTS antenna is designed in such a WAY that i cover cell area in which it is PLACED with frequency allotted without interfering other cell signals. The design process of selecting and allocating channel groups for all of the cellular base station within system is called frequency reuse.
