1. What do you mean by multipath propagation? Explain the effects of multipath propagation briefly. Calculate the median path loss using Okumura’s model for the distance of 30Km with base station antenna height of 30m and mobile station height of 2m in a suburban environment. If the base station transmitter radiates an EIRP of 1KW at a carrier frequency of 900MHz, find the power at the receiver (assume a unity gain receiving antenna).
