an idea that might be useful.. you may split the outgoing channel from incoming channel ; it's usually the sending/outgoing that is slow/difficult (small device not able to transmit too far, think a phone in a rugged mountain). Some satelite-internet providers work this way, using satelite for the send direction and some other usual channel for the receiving. good luck
