Consider a single cell supporting 300 active users uniformly distributed within the cell and make simultaneous access to the system. The cell is divided into three sectors and each user employs a directional antenna and voice activity provision. The effective Eb/I0 at the input of a conventional receiver is 4.5 dB and the noise contributions from the channel are negligible. Calculate:

i. Maximum number of users in each sector

ii. Processing gain in dB

iii. The processing gain in dB that is required to keep the probability of error for the same total number of active users the same as when the cell sectorization and voice activity monitoring techniques are not used.
