So i guess what we need is for prices to drop for "last mile" deployment
Actually prices are going to go up by at least twice as much, and at least a month wait time for installations.
2.4 GHz is a RF waste land with a dozen APs on 200 foot towers or 120 foot water towers, all within a few miles of each other, and then you have the -70 dBm noise floor from SOHO wireless gear. 5.8 GHz is getting to be the same way, but at least the more tighter beamwidth antennas is helping; as well as 200 watts for the PtP backhaul links.
The next stage is 3.65 GHz and the equipment costs twice as much and each user's radio has to be licensed (it takes about a month for the FCC to process your application).
