Question

A transmitter provides 32W to an antenna having 12 dB gain. The receiver antenna has a gain of 3 dB
and the receiver bandwidth is 30 kHz. If the
receiver system noise figure is 8 dB and the
Carrier frequency is 1800 MHz, find the maximum
T-R separation that will ensure that a SNR of
20 dB is provided for 95% of the time. Assume n=4, Sigma =8 dB, and do = 1km.
