Technically, the problem is that when you attempt to put together the 
requirements of "high speed", "wireless" and "distance" they become a 
contradiction in terms

And when you also add "high delay" to the mix then it enters the realm 
of engineering fiction.

Reliable high speed data transport in the IP world (TCP in other words) 
assumes low constant delay and extremely low bit error rates.
