A shadowing model is used for determining the coverage of a wireless communication. The shadowing model parameters are Path loss exponent y=-3 d, = 1km L, = -111dB O = 6dB a) What is the probability for the propagation loss at 4 km from the transmitter to be greater or equal with -135dB, i.e. Lpe(4km) > -135DB. We call this probability the coverage at 4 Km. b) If the minimum power at the receiver (P,) for a good reception is -100dBm, and receiver antenna gain (g,) is 6dBi, what is the required ERP at the transmitter for 84% coverage at 4 Km. c) Calculate the ERP from (b) in mW A shadowing model is used for determining the coverage of a wireless communication.
