A new phone company wants to provide very cheap voice-only cell phone capability to 200,000 simultaneous users in San Francisco. They transmit only 8kbs per duplex channel using FDMA (frequency division multiple access) and BPSK (1 bit/Hz). The FCC mandates that they use 1kHz of guard band on each side of the channels.
a) For a system of 20 clusters, what total bandwidth do they ask the FCC for?
b) If they use a frequency reuse scheme of 12 per cluster, how many channels are there per cell?
