A mobile telephony operator is given 24 frequency channels, each of which can support 6 users,to operate a mobile phone system in a city with path loss exponent n=3.4. You are their chief engineer and need to design several key parameters for the system. In particular, you need to determine the cluster size, whether omni-directional or sectored antenna should be used, and if
sectored antenna is selected, whether 120° or 60° sectored antenna should be used. The design objective is to maximize the system capacity. Assume that the minimum required S/I for the mobile phone system you used is 14dB, and you would like to have a grade of service (GOS), or blocking probability, of 0.1%.
a) Design the system and give analytical analysis to support your chosen parameters and design.
b) Point out and discuss any issues where the analytical comparison does not address and how
your design compares with the alternative in those issues.
