LOW-Earth Orbiting have more advantageous in Mobile based communication devices like PDAs, Cell phones and automobile communications. The LOW-Earth Orbiting is a satellite of orbit of few hundred miles. It takes very less time for taking the round trip, as are the power requirements for earth-bound communication devices. The LEO earth orbit moves very fast due to their orbit. So due to this reason the fleet surface is needed to maintain the communications. When LOW earth orbit moves out of area the other one moves in.
