An urban area has a population of two million residents. Three competing trunked mobile networks (systems A.B. and C) provide cellular service in this area. System A has 394 cells with 19 channels each, system B has 98 cells with 57 channels each, system C has 49 cells, each with 100 channels. Find the number of users that can be supported at 2% blocking if each user averages two calls per hour at an average call duration of three minutes. Assuming that all three trunked systems are operated at maximum capacity. compute the percentage market penetration of each cellular provider. The total carried traffic is 12 Erlangs, 45 Erlangs and 88 Erlangs for system A, system B and system C respectively.
