To be able to increase the capacity of the system, frequencies must be re-used in the cellular layout (unless we are using spread spectrum techniques). Frequencies cannot be re-used in adjacent cells because of co-channel interference. The cells using the same frequencies must be dispersed across the cellular layout. To serve hundreds of thousands of users, the frequency must be reused and this is done through cells. The area to be covered and subdivided into radio zones or cells. Base station positioned at the center of the cell. Data communication…
