(b) Consider a cellular network in City A with a cluster size of N=9, a Grade of Services (GoS) of 2%, 60 channels allocated to a cell, and a traffic intensity per user, A., of 0.01 Erlang. (i) Calculate the traffic intensity offered by each cell if the system deploys 120 sectoring. (4 marks) (ii) Calculate the number of subscribers that a cluster can offer. (3 marks) (iii) Criticize the number of users that can be supported in City A if the telecommunications provider reduces the sector size of each cell from 60 to 1200 sectoring. Calculations should be used to support the answer, and your assumptions should be stated. (6 marks)
