But it's not. This requires - at present - a databasing system that can methodically lower interference between nodes and divvy up the bandwidth between different houses. Because the frequency penetrates so well and has so much distance capability, interference is a constant and potentially crippling problem. That also causes major issues with country borders, since it is easily possible to interfere with transmissions of another base station from 100+ miles distance.
The article makes it all sound like you just buy some device, plug it in and whallah, you're online at up to 600Mbps. Not to mention that 600Mbps refers to "air speed," which means all the signalling, all the channel boundaries being removed, all the error correction data, all the retransmissions, etc. In other words, nothing like 600Mbps to the end user. But hey, don't let that get in the way of $ale$ amirite?!
