> building a few towers to broadcast WiMAX Easier said than done. It might be workable in dense urban areas where there are already lots of tall buildings, but getting approval to build towers in many residential areas is like pulling teeth. To support peak usage hours when everyone is at home HD streaming hulu and netflix, even with WiMax, you will need way more (i.e. smaller) cells than wireless carriers have today, which means lots more towers. Plus you'll need fiber going to all of these small cell towers, which means you're half way to FTTN anyway. I think wireless internet might fit some niche situations well, but I'm skeptical there is significant capital or long terms savings in the general case. Not to mention that it will never be able to compete with fiber on latency or bandwidth.
