A certain area is covered by a cellular radio system with 84 cells and a cluster size of N. 300 voice channels are available in the system. Users are uniformly distributed over the area covered by the cellular system, and the offered traffic per user is 0.06 Erlang. Assume that blocked calls are cleared and the designated blocking probability is 1%.
Determine the maximum carried traffic per cell if cluster size N = 4 is used. Repeat for cluster sizes of 7 and 12.
Determine the maximum number of users that can be served by the system for a blocking probability of 1% and cluster size of N = 4. Repeat for cluster sizes of 7 and 12.
