Consider the following Wireless Transmitter/Receiver pair: Antenna Gain = 6dBi Antenna Gain 6dBi Transmitter Receiver RX TX Cable Loss -8dB Cable Loss - -8d8 The cable loss on each side is 8 dB (or -8 dB gain), and the transmitting and receiving antennas each have a +6 dBi gain. The transmitter is configured for a power level of 150 mW. Suppose the transmitted signal has a frequency of 5 GHz and the distance between the transmitter and receiver is 0.5 km. INFR3720U Assignment#4 Due Date: March 20, 2022 (11:59pm) a. What is the transmitter EIRP in dBm? (10 Marks) b. Assuming Free Space Path Loss as the only signal impairment in this system, what is the minimum RSSI in dBm that the receiver RX should be able to detect? (10 Marks) c. If the distance is increased to 3 km, how much the transmitter power level (in mW) should be increased in order to maintain a minimum RSSI of -85 dBm at the receiver? (10 Marks) d. Suppose we keep the transmitter power at 150 mW, and instead replace the antennas on the transmitter and receiver with parabolic dishes with a gain of 15 dBi each. How far the distance could be extended while maintaining a minimum RSSI of -85 dBm at the receiver?
