Re:Channel capacity will probably be bad. (Score 1)

But where is the noise coming from? In space there is no friction and if the payload is delivered with light/laser is the any limit to the channel capacity? The Utilization of SATCom uplinks could/would hold back the channel capacity untill future developments in the multiplexing area are resolved. But the satellite to satwllite connection could be unlimited. On the topic of noise the only time we would have the noise problem is when the signal is leaveing and entering the atmosphere and of course when you start using multihops, but the digital signal would be cleaned up at each intermediate hop and a clean signal would be sent to the next destination. How many channels can you put across a beam/pulse of light/laser? Right now it is only determined by the hardware configuration transmitting the signal as light/laser technology is just starting to get tapped and understood. Just a few comments on this interesting subject so let me know what you think.
