WTTR + for coax. In an interview with Sean Buckley, Small said “The other thing that we have separately talked about is we’re exploring the use of That technology can work over coax or twisted pair so that’s an essential companion way to deliver service where a property does not have Cat 5 or Cat 6.” DirecTV has millions of lines with an antenna on the roof and either coax or ethernet cable throughout the building. Their first homes, in Minneapolis, are only offering 100 megabits. They want to use and take that to 500 megabits or more.

AT&T continues to be coy about whether they will turn their trials into volume deployment. They have vendor proposals on the table; is ready to go. As Century says, it works as promised.  It's not very expensive, according to the quotes I'm hearing. Vendors are forward pricing to win the business. Century has made the leap to; 12 telcos are in early deployments, 60+ in trials. When I saw AT&T was doing WTTR (wireless to the roof), I assumed it would be So far, it isn't.
