A wireless communication company is installing a base station near one of Kuwait's major highways. Drivers and residents make phone calls at a rate of 30 calls/min, the inter-arrival time of calls is exponentially distributed. The call duration is also exponentially distributed with an average of 3 minutes. Each call occupies a channel with 40 Hz bandwidth for its duration. During testing, a base station with 25 channels was blocking callers with a probability of 0.1163. Design the bandwidth of the system in He such that a subscriber trying to make a call anytime will NOT be blocked with a probability of 0.9 or more?
