Concepts of Wireless Networking - Old Questions

6. Consider a cellular system with 416 radio channels available for handling traffic. Suppose 21 of their channel are designed to control channels. Let the average channel holding time of a call be 3 minutes, the blocking probability during busy hours be 2%, and the frequency reuse factor be 9.

a. Determine the number of calls per hour.

b.Determine the signal to channel interference ratio in dB.(3+3)

[At 2% blocking probability with 44 available channel, the traffic load is 34.683 Erlanas]
