Assume that the allocated spectrum for a cellular system is 25 MHz in bandwidth, for a single link, and that each channel uses 200 kHz.
Also, assume that 50% of the users generate a traffic of 0.25 Erlang/user, while the other 50% generate 0.02 Erlang/user.
For cluster sizes N = 3, 4, and 7, compute the maximum number of users per cell, at blocking probability 0.02.
