design a broadband wireless link that operates in both directions from earth to a LEO satellite that has an orbital height of 150 miles. calculate the gain for a maximum coverage antenna on the satellite, the required number of satellites, and the required transmit power on each end to support 10 MHz wide noise-limited links at 1.5 GHz with a 2 dBi antenna on the handset and noise figures of 0.4 for both the space-borne and handheld receivers. Assume that BPSK modulation is used with a required bit error rate less than 1 in 100,000.
