Another generic, thin-on-facts hype article about the "whitespace". I'm disappointed in Slate. With all the vacuous pieces around, it's difficult to even find out which frequencies are being made available. Here's an article from 2007 with some facts: http://arstechnica.com/hardware/news/2007/04/white-space.ars http://arstechnica.com/hardware/news/2007/04/white-space.ars Basically new mobile devices will be allowed if they can actively dodge TV channels, in the 50-700 MHz range, and use the spaces in between. Truly the only advantage of these lower-than-wifi frequencies, as far as I can tell, is less signal attenuation (over distances and through walls). That means more potential for crowding, too. Plus I assume you need a longer antenna for the longer wavelength. I haven't been able to find any good info about potential data rates. In North America, 900-930 MHz is already unlicensed and used for some cordless phones and wireless transmitters. Remember that big antenna sticking out of your first cordless phone? (Before the fancier 2.4 GHz ones that interfered with your home wifi.) Anyway, new unlicensed bands is exciting, even if no single frequency is unused everywhere in the country, but I just don't get the "super wifi" / "wifi on drugs/steroids" angle without more facts.
