Consider a cellular system with a total bandwidth of 30 MHz. Each full duplex voice or control channel uses two 25 kHz simplex channels. It is assumed that 1) the system uses a 9-cell reuse pattern and 0.75 MHz of the total bandwidth is allocated for control channels;
2) the system service area consists of 50 cells; 3) the call blocking probability bound is 2%,as given by the Erlang-B formula. If the o?ered tra?c per user is 0.025 Erlangs, calculate:
(a) The tra?c load of each cell and the trunking e?ciency;
(b) The total number of users in each cell and in the system, respectively;
(c) The number of mobile users per channel in each cell and in the system, respectively;
(d) The maximum number of users in service at any instant in the system.
