Notes:
Start with a fundamental question of which there are two parts.
First part relates to design of system – concerns the wanted signal:
meets requirement in terms of signal strength, SNR, BER?
e.g. provides service to > 99% of population?
provides service for given % of time; particular time of day; particular season of year?
provide a service free from interference; free from distortion or errors?
To answer, need to know something about the propagation of wanted signal.
