FCC on Ultra-Wideband, DSL Services
ibirman writes: "According to Yahoo, the FCC has approved limited use of Ultrawideband (UWB) technology above 3.1 gigahertz. The article states that Sprint PCS among others has been campaigning to keep the minimum above 6 gigahertz claiming "interference". From what I have read, interference is not an issue, so I wonder what their real agenda is? Funny that the article does not mention that UWB could revolutinize high speed wireless networking." There's a Newsbytes story that decribes an upcoming ruling on DSL providers, which would exempt DSL carriers from the open-access requirements in place for most telephone services. There are a few links to statements on the front page of fcc.gov, but I don't see the actual orders for either of these yet.

Larry Fullerton, now of Time Domain, invented a radar and wireless system based on pulses of energy less than a billionth of a second in duration. The scheme is known as ultrawideband. Although ultrawideband pulsed radar has been around for decades, the U.S. Patent and Trademark Office decided in 1987 that Fullerton's system was original enough to be patented.
In the early 1990s, however, Thomas E. McEwan, then an employee at the Livermore lab, came up with a related idea for a "micropower impulse radar" that employed different circuitry and worked at much lower power. His device can function for years on a couple of penlight batteries, he states. He got patents, too, and assigned them to his employer, which started licensing the invention to manufacturers. But McEwan failed to cite Fullerton's invention as "prior art" in his original patent application.
Sprint backed the wrong horse and spent millions in licensing fees to Livermore lab. Their opposition to UWB is pure vindictiveness.
Now Time Domain refuses to license UWB to sprint, putting them at an extreme disadvantage to ATT and other competitors.
Beautiful technology though... this is one of those real "could change the world" technologies like the step from Analog to Digital signaling
If voting were effective, it would be illegal by now.
As you can imagine, this introduces some inefficiencies in routing! The airlines would desperately like to go to "Free Flight", which would allow them to route airplanes as more or less as desired (this is a vast simplification for you aero-nauts out there, and leaves out the problem of hubs entirely).
But Free Flight depends not only on GPS, but the advanced location services that the FAA and other GPS consumers would like to roll out over the next ten years. Those services will require absolutely pure signals on the existing allocated freqs, and possibly more freqs as well.
So they don't want anything messing with the GPS signal.

"Should the FCC reclassify digital subscriber lines (DSL) as an information service as opposed to a traditional wire-line service, it could effectively loosen federal rules that require Bell companies and other incumbent carriers to offer their competitors equal access to the telecommunications networks they control."
What the hell? After the Bells displayed their ability to cut of CLECs like they were batting down baby seals within the existing rules?
What world is the FCC living in?
had a story about this on Morning Edition this morning.

Here's the audio file of the segment:

A commentator on there seemed to think it would interfere with all sorts of things acting like a "layer of jelly" which the poor little GPS device could not operate through.
Most people would die sooner than think; in fact, they do.
