A base station is located at the center of its coverage area. A mobile receiver present in the coverage area receives a power of -80 dBm. The receiver's sensitivity is -92 dBm, The free space path loss between the transmitter and receiver antennas is 100 dBs. The base station transmitter and the receiver antennas have gains of 1 dBi, and 3 dBi, respectively Assume other losses (cable/ connector losses) to be negligible. (a) Calculate the base station transmitter power (in Watts). (b) Whas the fade margin, if any, available in the system? (c) Suppose we need to increase the fade margin to 20 dBs in the system, and the only choice available is to change the transmitting antenna. What will be new transmitter antenna gain in dBi)? n A base station is located at the center of its coverage area. A mobile receiver present in the coverage area receives a power of -80 dBm.
