In the US, 70, 80, and 90 GHz are "licensed lite"; you do have to register them. Apologies for envisioning the delicious irony of the database being swamped with trying to track and coordinate 300' links. Not to mention that, if memory serves, there's a fee to register each one of those links.

57-64 GHz, on the other hand, is license-exempt.

The day is going to happen in the "not so distant" future when there will be CMOS based 70 to 90 Ghz radios the size of a pack of smokes. These will only effectively send data about a few hundred feet. These radios will do over 1 Gbps from day one. The idea is to run them back to back from street light pole to pole and have WiMAX, Wifi, 802.11a (insert your favorite client platform radio here) as the client access device to serve a few homes or businesses around the poles.. This gives us a platform for broadband, telephone and cable television all over wireless. This is not a pipe dream. I am about 2 weeks from having my first pole agreement signed. It is going to happen.

The 70 Ghz gear is not going to be a long haul solution. It is going to be a real nice high throughput short haul solution to compete for triple play in cities and even smaller towns eventually. I plan to help prove this as a viable broadband platform in my own community. Now I just wish my friends at Intel would hurry up the development of those CMOS radios! They have all the patents and prototypes today. Bring on the GigE through the air!
