Wireless Network question?

Hello Friends,

Assume that we wanted to deploy an analog FM AMPS system with half band of 15KHz rather than existing 30KHz. Also assume that in analog FM carrier to interference ratio (C/I) requirement is inversely proportional to the square of the bandwidth (4 time increase in C/I for dividing the band into two).
a) What is the required C/I in dB for the 15 MHz per channel if the required C/I for the 30 KHz systems was 18dB?
b) Determine the frequency reuse factor K needed for the implementation of this 15KHz per user analog cellular system.
c) If a service provider had 12.5MHz band in each direction (up-link and down-link) and it would install 30 antenna sites to provide its service, what would be the maximum number of simultaneous users (capacity) that the system could support in all cells? Neglect the channels that are used for control signaling.
d) If we use the same antenna sites but a 30KHz per channel system with K=7 (instead of the 15KHz system) what would be the capacity of the new system?
If someone could help me out with this problem, I would really appreciate it!

Thanks And Regards
Steve Knight
