Tom, I believe there is a huge advantage to being able to use HPOL and VPOL at the same time with the same 20Mhz channel and get twice the bandwidth. Its sort of like your personal gps sync within the device. Realistically (for me anyway) I find that if there is strong noise on a give channel and its close enough (same tower / site) than changing the polarity won't help make the freq usable any way. Therefore I argue that MIMO (2x2) allows for BH use the actual more efficient use of spectrum. I do not compare that at all to the same as using two different 20Mhz chunks of spectrum and argue that you can indeed get twice the bandwidth out of the same 20Mhz (or 40Mhz if your environment allows) spectrum.
I'm seeing it right now in my test gear or I'd be a skeptical as the bunch... I like what I see so far but my testing has been somewhat limited. I'll know a lot more this time next month. I'm sure this discussion will do nothing but get more interesting in the near future when the rubber hits the road.
