The FCC's release says it's been allocated 5.850 - 5.925 GHz. The press release (it's a PDF) has some background on the service, and also a few notes on things that have to happen before the use of this new radio service can become widespread.
Oddly enough, in my apartment at UTC, we have a double outlet on its own 20 amp circuit, and three other outlets on a second 20 amp circuit in each bedroom, plus a 100 mb lan and a telephone plug in each room.
Only bad thing is there's only one cable TV jack, and it's in the living room. Easily solved with about 50 feet of coax and plenty of splitters...
"Open spectrum" being the status quo in the 2.4 GHz band is sorta true... 2.4 GHz spread-spectrum data applications are secondary in nature to operations by amateur radio operators, and more importantly, television remote pickup stations (i.e. live shots), which occupy that band as three ENG channels.
Being that the TV stations which use those channels for live shots are licensed, they can, and have, taken action against some ISPs whose 802.11 equipment has caused interference to their systems. The SBE (Society of Broadcast Engineers) has lots of information on this.
The biggest obstacle to the "open spectrum" is incumbent users and their investment in current technology... just to displace the lower end of 2 GHz point-to-point users to clear it out for PCS is costing many millions of dollars... according to the PCIA, an average path relocation costs $220,000, and over $250,000,000 has been spent to date to clear that chunk of spectrum for the PCS folks.
Bet AOL is watching closely... think about it - lighter CDs mean each one they mail out weighs less, so they pay less postage, not to mention they can make one every.3 second.
KT-Tech is apparently trying to get into the two-way wireless communication market. One question to ponder: Would we really want cameras on our cell-phones?
Not on my cell phone, but being able to stream video over a narrowband channel has huge implications in the public safety community.
Firefighters and others have been wanting this ability for some time, so they could send back video real-time of natural disasters (like tornadoes) or of hazardous materials incidents, and right now that capability just doesn't exist without reliance on a third party.
"... but brings the wireless providers into the mix (it's probably their cell-phone towers)."
Not really... most of the towers are owned by companies like American Tower, SBA, Signal One, and others who just lease the space to anyone who can pony up enough $$$.
How often? Too often, judging from the news reports over the last few years...
I'm certainly not saying that if it's old it should be replaced - we have a 386 running Netware for MS-DOS at work as a print server... it sits and runs, and works perfectly fine. It's actually the lowest maintenance machine we have!
Old is not bad, but old such that reliability is impaired is bad.
Well, maybe some software should be scrutinized - for example, the software that runs the FAA's outdated and archaic air traffic control systems, or that which runs a CAD system for your local 911 center.
But, as far as engineering "things," be them buildings, tunnels, bridges - minor miscalculations can have deadly consequences. If my OS decides to crap itself, or if Half-Life decides to lock up, my life as I know it isn't gonna change - yes, I'll be a little irritated, but it won't kill or maim anyone like a building collapse or bridge failure could do.
BellSouth requires the domain you use in the from field to resolve to a valid domain, which seems to be a much better solution than just requiring you to use their domain.

Add it all up, I pay more in tax and FCC "fees" than I do for the line itself...

So, open spectrum still has a long way to go...

Isn't technology wonderful?
