I wouldn't hold my breath.

Short range, maybe the next standard after N. For outdoor usage, ptmp, it seems to be hard enough to keep 64 QAM from dropping to a lower modulation.

Even with a -50 signal, high 90's CCQ constantly, the slightest bit of noise will make the link drop to 48 or 36. 128 or 256 QAM would be even more susceptible.
