Arthur T Knackerbracket has found the following story:
D-Link and Redmond have put the paddles on 802.11af, charged the machine, and hit the button.
The 2013 amendment to Wi-Fi is an air interface for "white space" frequencies (from 54 MHz to 698 MHz in the USA; Europe and the UK use a more realistic 490 to 790 MHz), with a maximum per-channel 35.6 Mbps (16 channels can be bonded together to get nearly 600 Mbps).
It's primarily a point-to-point link service rather than a user-access technology, and so it doesn't interfere with TV transmissions, 802.11af uses a cognitive radio to sense other spectrum users, and a localisation database to keep track of broadcasters.
Data rate, however, isn't the main story: compared to 2.4 GHz, TV frequencies cover a lot of ground, and that's the angle D-Link and Microsoft are touting.
The standard is designed for links up to 1 km in range, the kind of reach that 2.4 GHz Wi-Fi can only manage with a cantenna.
The two want to use 802.11af for rural/regional services in underserved areas, with a phase-one pilot currently underway in the US.

Meanwhile they're pumping blue pills and pornography into the West Bank settlements, eh?

This radio scheme sounds ripe for software cheating abuse... and also very practical given the massive unused bandwidth recently devalued by over-the-air television's rapid decline. Cable was bad enough, but now with Netflix, et.al. the newspapers have a story to tell to broadcast TV. Broadcast television bandwidth has always been copious and underutilized, and now I think we can all agree that it is unlikely that we will ever have a need for 80+ broadcast channels in a single market area.
