Question 3 [15 points]: A base station transmitter, located at the center of its coverage area, is transmitting 100 mW power. A mobile receiver present in the coverage area receives a power of -80 dBm. The receiver's sensitivity is -95 dBm, The base station transmitter and the mobile receiver antennas have gains of 1 dBi, and 3 dBi, respectively. Ignore cable/ connector and other losses. (a) Calculate the free space path loss (in dBs) between the transmitter and the receiver antennas. (b) What is the fade margin, if any, available in the system? Question 4:[10 points] In a slotted ALOHA network, we have a total of 15 stations and each station transmits 20 frames/sec., on the average. The fame size is 200 bits and the wireless channel supports the data rate of 100 Kbps. Calculate the throughput in the network.
