Suppose you have a receiver whose sensitivity is -100 dBm (minimum received power with which it can operate) and a signal is transmitted to it at a power of 1W. At both ends of the link there are antennas with 3dB gains; installed at heights of 5 and 1 meter, respectively. The stage is flat terrain with no obstacles. What is the maximum distance that these transmitters can be separated? Assume an operating frequency of 700 MHz.
Please help with this question, please wite clearly and explain clearly, thanks.

Q1. A link is operating at f=60GHz & 500 MHz bandwidth. The Tx & Rx antennas are square-shaped with 2m and 50cm in dimension, respectively. The Tx-RX distance is 500m. The aperture efficiency is 0.9 for Tx and 0.5 for Rx. The Tx power is 30 dBm and the receiver threshold is -100 dBm with Te-900k for Tx and 700K for Rx.. Calculate (a) the received power (b) the path loss (c) the link margin, and (d) the received SNR.
2. For link to be maintained between a geosatellite and an earth station about 35,786 km apart, calculate the carrier power (in dB) necessary giving the following antenna characteristics: a. 60% efficiency b. 2.5-cm wavelength c. 1.3-m diameter transmitting dish d. 1.0-m diameter receiving dish e. To ensure high service quality, it is suggested that the carrier power at the receiver input must be at least -116dBW.
