That will provide several day's reading and a precis of things already degubbed to routine usage . I at first failed to take note of the fact that E-M-E is * NOT * a mere doubling of the path losses for one way but a much more complex figuring . Also I was misinformed as to the concept of bandwith being limited by distance . POWER demand , Beam dynamics and system noise budget as affected by the first 2 factors are the speed bump . Now if we traded both bandwith and power for complexity and low tech arguably a large enough lunar helio mirror array could provide optical comms with telescopes as receptors . Oren " I bet that converging Ham Radio , Open Source advocacy , SciFi Fandom and some loose cash could stand the established order on it's ear for all our betterments " _________________________________________________________________ Learn how to choose, serve, and enjoy wine at Wine @ MSN. http://wine.msn.com/
