Just to throw a question out there to the engineering types. Is this, or could this be a major solution to the "last mile" problem that most of the industry is concerned about? It is mentioned in the article that the user can expect from 1/2 to 3 times T1 data rate speeds which everyone I know would be thrilled with. With out that physical connection to the network.

Yes. Run fiber down the street. Connect each house using UWB. The only threat to this scenario would be for UWB to replace traditional broadcasting technology entirely (which is technically possible, but politically difficult). Were that to happen, fiber would go the way of copper--and so would all those currently-expensive broadcasting licences (not to mention the FCC itself).

Technological revolutions can sometimes be seen as threatening to existing businesses and investments, and therefore cause short to intermediate term devaluations of entire market sectors. Think of UWB as analogous to integrated circuits/personal computers, circa 1970.

In metropolitan areas especially, I envision this technology spreading to hand held PDA's and communication devices (e.g. hand held phones) where each device also serves as a node in a huge interconnected network negating the need for an ISP or cellular service provider and allowing virtually free communication and data services for the price of the device alone. Unless the government jams the frequencies, they won't be able to stop this from happening.

That was my thinking also, excuse while I go do some plotting and scheming. (grin)

Thanks for the ping!

Good article!

I wouldn't go so far as "virtually free", but I can envision a local or city type of Public Utility, with prices low enough to cover upkeep and maintenance of the system.

Possibly this could be a contractual thing with the local cable company providing UWB to the city.
There are many possible options.
The telephone companies may even be receptive, if they could then forego the inconvenience of having to run wire/fiber optic cable to each and every residence.
Consider the cost savings for residential connection alone.
Simple running fiber optic cable down streets or alleys, and setting up transmitter stations at the corner of the block would be sufficient to provide service to a block-wide coverage area.

"Yes. Run fiber down the street. Connect each house using UWB."

Interestingly, I live in an area in far North Raleigh, NC, that is "new" and.....let's just say "upscale". There is fiber to the curb here. Sprint, the local provider, offers (and we use) a high-speed Internet option that uses no modem (it isn't DSL; it isn't cable modem). They literally provide an RJ-45 jack in your home, and you connect directly to their network. They use ONU's (Optical Networking Units) to interface the "copper" from the homes to the fiber. Works like ten champs.

Of course, in the house here, I've set up a wireless network. I opted for 802.11b due to the still-rather-prohibitive cost of 802.11a gear, but mainly because the sustained data rates over "high speed" internet connections are still well within 802.11b range. Still, I love it. :)

I am looking at getting a laptop with High Rate wireless LAN PC card and the associated Gateway.

Uses the popular IEEE 802.11b wireless technology. Good to hear it works as advertised!

The frequencies allocated, and the FCC Part 15 restrictions (particularly the 1W EIRP) will keep UWB devices "short-range" only for now.

The FCC permits quite a few "imaging" applications (think "radar") for automotive and specialized uses. The blurb on telecomms from the FCC Press Release for the FR&O makes it clear that you're not gonna cover too much real estate with these puppies.

You might find this of interest: This is from 2cpu.com:

_______________________________

While prowling for even more news, I stumbled upon a link to an 802.11b networking roundup over at PCStats. 802.11b might not be the latest and greatest, but it's still an affordable means of adding some wireless capabilities to your LAN.

Unlike a wired network, a wireless LAN, or WLAN transmits your data (personal, public, or whatever) through unlicensed airwaves that anyone within range can potentially intercept. There are ways to safeguard that data - and the first such step is enabling 64-bit or 128-bit Wired Equivalent Protocol (WEP).

The laptop owners out there will certainly find such an article of interest. People ask me why I'm still "wired" and I just reply that it probably has something to do with the amount of pepsi I drink (Sorry, that was lame). If you're currently running a wireless network, enable WEP. Read on.

You guys are missing the point. The idea would be for these devices to become part of a huge public peer to peer network. These individual devices would work together to handoff and route digital packets (voice, data or video) between thousands of other individually owned devices. By this method of a packet being handed off from one device to another, a person could communicate with someone else on the other side of a city or the other side of the planet if the world wide web was also used.

I am looking at getting a laptop with High Rate wireless LAN PC card and the associated Gateway.

I've been running 802.11b for about 8 months for my internal network. Since WEP, the security for 802.11, is badly broken, I put an OpenBSD gateway between the wireless access point and the rest of my internal network. The OpenBSD box runs IPSEC as does my laptop, creating an encrypted link across the wireless connection.

Installing the NetGear wireless card on my laptop was as easy as installing the PCMCIA card and letting autodetect find it. I set up IPSEC to start automatically on bootup, as well as the firewall software the keeps anything but IPSEC from connecting to the laptop.

It was a snap. It stays up for weeks at a time while I surf the 'net from in front of the television. Occasionaly I grab the laptop and wander out onto the porch with a beer. But I expected it would work perfectly and stay working perfectly.

You see, I run Linux on my laptop. I have come to expect stability, ease of use and security. And once again, I wasn't disappointed.
