3. Assume a receiver is located 10 km from a 150 W transmitter. The carrier frequency is 6 GHz and free space propagation is assumed, Gt = Gr=1. 1. Calculate the transmit power in dBW and in dBm. 2. Find the power at the receiver in Watts and dBm. 4. There are two types of trunked system, Blocked calls cleared also known as M/M/m/m queue and leads Erlang B formula, and Blocked calls delayed leads to Erlang C formula, describe the mathematical model of the first type queue, M/M/m/m. Give a mathematical expression on the probability of blocking.
