What would happen if an uplink and downlink had equal frequency. I know 'swamping' would occur, but what IS swamping ? Would stationary waves be set up ?
I'm not sure I fully comprehend.davenn said:The local strong signal transmitter would totally desensitise the receiver and as a result the receiver would "hear' little to nothing of the weak signal coming from a distance
ie. the transmitter would "swamp" the receiver
cheers Dave
davenn said:That would also play a part
So it all goes to show why they use separate uplink and downlink freqs so they don't have all those engineering hassles :)

Swamping in satellite communications refers to the phenomenon in which a satellite receiver becomes overloaded with too many signals, causing a decrease in the quality of the received signal.
Swamping can cause interference and reduce the signal-to-noise ratio, leading to errors and degraded performance in the communication system.
The main causes of swamping include high transmit power of the satellite, signal reflections from nearby objects, and interference from other neighboring satellites or terrestrial transmissions.
To prevent or minimize swamping, satellite designers can use directional antennas to reduce the amount of energy radiated in unwanted directions, employ frequency and polarization diversity techniques, and carefully plan the placement of satellites to avoid interfering transmissions.
Swamping can significantly degrade the performance of a satellite communication system, leading to increased error rates, lower data throughput, and decreased reliability. It can also cause interruptions or complete loss of communication in severe cases.
