A spacecraft located 100,000 km from the earth is sending data at a rate of R bits/s. The frequency band is centered at 2 GHz, and the transmitted power is 10W. The earth station uses a parabolic antenna, 50 m in diameter, and the spacecraft has an antenna with a gain of 10 dB. The noise temperature of the receiver front end is T0 = 300 K.

1. Determine the received power level.

2. If the desired = 10 dB, determine the maximum bit rate that the spacecraft can transmit.
