The problem with WISP deployments is without exclusive use of spectrum (which you have to win at auction from the FCC vs Verizon/at&t/etc) you can't do LTE-type deployments where you can count on a low noise etc. Beyond that, keep in mind that LTE 30-50Mbps is dependent on the spectrum set on a sector. If everyone ditched the local MSO & Telco for LTE it would get so overloaded that everyone would be saying it sucks and switching back to the MSO. Generally speaking you are left to deal with licensed microwave in the ~$10k per link for ~260Mbps or unlicensed microwave in 2.4/5.8Ghz where you have to deal with noise from every WiFi router and other random junk. Depending on how many other devices are out there you get less than 1 Mbps to 200 Mbps depending on spectrum availability. The technology for WISP deployments is fairly mature, to the point that if you are using straight-up WiFi you are doing it wrong. If you want to learn more, the current market leaders in the US for unlicensed microwave are Cambium (former Motorola)'s PMP series and Ubiquiti's AirMax series. Check them out. Anyway, there just isn't enough spectrum available to do a robust city-wide WISP network with significant uptake.
