Question: 1. Consider free space path loss in your wireless communication systems: Where P t = signal power at transmitting antenna P r = signal power

1. Consider free space path loss in your wireless communication systems:

Where

Pt = signal power at transmitting antenna

Pr = signal power at receiving antenna

= carrier signal wavelength

d = communication distance between antennas Usually there is a minimum requirement of Signal to Noise Ratio SNR related toPr. Please nominate at least two strategies in your communication system in order to increase the communication distance d. Explain why. (1 point) 2. Suppose a 512kbps point-to-point link is set up between the Earth and a rover robot on the Mars. The closest distance between the Earth and the Mars is 55Gm (55*10^9 m), and data travels in speed of light (3*10^8 m/s). (2 points) ]
