Is there any harm though? There is at least one other AP manufacturer
that really wants to test this feature, so I guess there will be products
on the market soon enough that support VHT in 2.4Ghz band.
Some day soon-ish, we'll benchmark this in an isolation chamber & over-the-air to see
how it actually performs.
Thanks,
Ben
