SOLAR SYSTEM

Detailed explanation-1: -9. Why are techniques like frequency reuse and spatial isolation carried out? Explanation: at times there is more traffic than there are transponders to handle it. For that reason, numerous techniques have been developed to effectively increase the bandwidth and signal-carrying capacity of the satellite.

Detailed explanation-2: -Technique for using a specified range of frequencies more than once in the same radio system so that the total capacity of the system is increased without increasing its allocated bandwidth.

Detailed explanation-3: -This technique employs use of narrow beamwidth antennas. Each of these antennas focuses on narrow region of the earth and hence will results into increase in capacity of the cell. This is because different earth stations can use the same frequencies.

Detailed explanation-4: -1 Answer. The explanation is: The original signal being transmitted from the earth station to the satellite is called the uplink, and the re-transmitted signal from the satellite to the receiving stations is called the downlink. Usually, the downlink frequency is lower than the uplink frequency.

Detailed explanation-5: -The downlink frequency in the C-band transponder is about. Statement A: Satellite communication uses different frequency bands for uplink and downlink. Total band of frequencies allocated for satellite communication is spread over. More items
