Sometimes people find that the impossible actually is possible. The world used to be flat too :)
... until their understanding increased. I have two radios on my desk that cost less than $500 for the pair including antennas that will do 100MB using MIMO technology. I also find that given the same frequency usage I get double throughput of non MIMO gear. I also find that the non-MIMO gear gets twice the throughput of the Trango gear I had, and that the Trango gear got more throughput than the last generation MOto gear etc.... You get the picture :) I'm calling this stuff a game changer, and its not even the Ubiquity gear (Mikrotik). Price is certainly cheap enough to play with in the near future... We shall see. All things aside, should work very well for PTP BH shots for unlicensed gear. I'd hate to be trying to sell a 10K unlicensed 100-300MB link right now with the industry changes coming about. You could spend $1000 and get two of them running together for redundancy / increased throughput / full duplex etc (I'd use OSPF to do this). The more expensive gear will still have its uses but this gear should fill a large unlicensed void that existed until now...
