The US May Finally See Widespread 'Super Wi-Fi' Deployment (siliconvalley.com)

The end of the FCC's spectrum auction last week "should give a clear indication of how much space will be available in each TV market for Super Wi-Fi," according to the Bay Area Newsgroup. An anonymous reader quotes their report: [T]he technology has promised speedy internet for rural citizens and to help urban dwellers get connected in buildings and rooms that are now twilight zones for Wi-Fi signals... And because the spectrum is regulated and largely reserved for television signals, Super Wi-Fi transmissions don't have to contend with interference from random devices like microwaves or cordless phones, as do signals in other wireless bands. Super Wi-Fi signals generally won't be as fast as regular Wi-Fi signals, but for many customers, they'll be faster and provide better service than what they'd get otherwise...

It's widely expected that there will be plenty of room for Super Wi-Fi in rural areas where there are few television signals, which is why companies like Cal.net and Q-Wireless have pressed forward with the technology even before the auction closes. The big question is whether regulators will preserve sufficient space for Super Wi-Fi in areas like New York and Los Angeles where there are lots of broadcast stations and in cities like Detroit and San Diego that have to share the airwaves with cities from other countries. If there's not enough space in those areas, Super Wi-Fi, in this country at least, will likely be relegated to rural areas.

    Because rural WiFi crowding is such a problem...

    So, Mr. Snarky City Guy, you really don't have any idea what you're talking about, do you? The problem isn't WiFi congestion in rural areas, it's the lack of any affordable infrastructure able to get broadband out to those areas in the first place. Having your WiFi busy on your property when your neighbor's WiFi is a quarter mile away is NOT a problem. But if neither of you can actually get those routers to connect to the internet because there's no there there, what's the point? There are millions of people who live where poor DSL, at best, is the broadband they can get - no matter what they're willing to pay. That, or laggy, expensive, very much capped satellite service with dial-up upload speeds. No cable, no fiber, no T-1 to your business ... just dial-up, and perhaps some 3G mobile coverage if you're lucky.

    This broadband desert starts happening just a few miles outside of most towns. You know, where the people who grow your food live.

    Rural WiFi is not the same thing your home WiFi, although it does use the same frequencies and technologies.

    Rural WiFi is used by wireless ISPs (that is, the rural equivalent to your urban cable modem or DSL connection). This is accomplished with directional antennas that concentrate the signal so that it can span five to 10 miles. They do this because it is prohibitively expensive to string fiber (or copper) when there are only a few customers per mile. Because the signal is so weak by the time it gets all the way to the receiver, interference anywhere along the "line of sight" path is more difficult to filter out.

    An urban dweller needs maybe a 500-foot circle of no interference. The rural need is a non-interference rectangle 500 feet wide by maybe 10 miles long, stretching from his roof-mount antenna all the way to the ISP antenna which likely is mounted on a grain elevator in a nearby town.
