| Abstract | The channel capacity of the present Metroliner telephone system is analyzed and methods are proposed to increase that capacity without increasing the overall bandwidth. To determine the number of channels required, calculations have been carried out using two available mathematical models: the Erlang Model and the Waiting Model. Three criteria have been used: (1) the probability that no channel is available; (2) the mean waiting time; and (3) the probability of having to wait at least t minutes. |
