Repeat the calculation for Problem 1 assuming typical mobile propagation conditions and a frequency of 800 MHz. What can you conclude about the feasibility of portable communication without repeaters over this distance in an urban environment?

Problem 1

Look at Example 10.1.

(a) Calculate the minimum transmitter power that would give line-of-sight communication at 27 MHz for the maximum distance set by the radio horizon. Assume free-space propagation.

(b) Repeat the calculation for free-space propagation at 800 MHz. Account, physically, for the fact that more power is required at the higher frequency.
