Intel Demonstrates 220Mbps Variant of UWB
MattyIce writes "InfoWorld has a story about a yet to be approved standard for a high-speed, short distance communications standard. Last year, Intel demonstrated 100MBPS speeds but they have bumped the speed up to 220MBPS this time." Fast stuff, but I imagine it'll be a long time before it comes to market. I haven't even upgraded my wireless network to 802.11g yet!
Technology keeps outdating itself... but some people can never accept it.
My $1000 486 10 years ago has seen a 99.9% decrease in value.
This $20 book published in 1998 has some idiot trying to get $5 out of it.
I've seen organizations rent computers for $30/month/each just to escape this madness.

a high-speed, short distance communications standard. isn't that called shouting?
The Hopi Indians were a tribe of Pueblo Indians. They live in northeastern Arizona. There name is short for Hopituh Shi-nu-mu which means "the peaceful people." The Hopi have different clans named after different animals and food. The Hopi occupied three mesas known as the First Mesa, Second Mesa, and Third Mesa. A mesa is a flat topped hill. The First Mesa is the easternmost mesa. The Second Mesa is in the middle. The Third Mesa is located in to the west. All three mesas can be seen from each other.
Homes
Hopi homes, or pueblos, were made out of adobe (a type of mud) and sandstone. These buildings were several stories high and had no doors or windows. One family's floor was another family's roof. To access these dwellings the Hopi put holes on the roofs of every house. Ladders would stick out of the hole so that the Hopis could get in and out of there houses easily. The Hopi would pull the ladders up when under attack so that no one could get into their homes. The people sat on built-in stone benches and slept on blankets on the floor. A pueblo may be as high as four or five stories.
Food
The Hopi depended on farming, gathering, and hunting for their food. Their main crop was maize (Indian corn). Maize was used for several dishes and other uses. Piki, a bread made out of blue cornmeal, was a special treat to the Hopis. To make piki, the Hopi women would mix blue cornmeal with boiling water to make the batter. Then the women would grease a stone griddle with toasted squash seeds. They would pour this batter onto hte stone griddle and wait a few seconds. When the piki was cooked, the women rolled it up and let it sit out. After some time it would become crispy. This was eaten at special ceremonies. Chukuviki is another special dish made of cornmeal. Moistened cornmeal was made into stiff dough and rolled into crescent shapes. It was then steamed or dipped in boiling water. One place this was commonly eaten was at weddings. Hopis could eat maize on a cob or make it into a drink called pinole, a mix of ground roasted dry corn and cold water. Small stalks of corn could be used for beddings. Pipe bowls were made out of corncobs.
The Hopis also grew squash, pumpkins, gourds, beans, cotton, onions, chilies, and melons. They gathered roots, leaves, berries, nut, seeds, and agave. Agave is an edible wild plant. People could eat its meat, and its juice could be made into a drink. It took two days to bake the agave in a fire pit. The heart of the plant's crown was used to make candy for the boys and girls. Mesquite, which is a small tree with edible pods that ripen in late summer was another food source. They would gather the pods and dry them in the sun. The pods would be pound into a sweet tasting flour, then moistened and made into a cake.
Hopi men hunted deer, rabbits, antelope, mountain sheep, and buffalo. The deer were hunted with bow and arrows. Hopi men would surround the deer. A man would scare the deer close to the hunters where the deer would be shot. Sometimes, hunters would light fire in a ring around the deer which would scare the deer and make them huddle close together where they could be easily caught. The rabbits were driven into nets and killed with hunting sticks which bounced and sometimes killed more than one rabbit. The Hopi asked the animals' forgiveness before killing them and politely told them they were on this earth to be food. Men and women, by working together, provided food for their family.
Clothing
Before coming into contact with white men, the Hopi wore animal skins or clothing made out of cotton. They wore sandals made out of plant fibers or moccasins made out of animal skins. Animal skin robes were worn in the winter. The Hopi also wore jewelry. Unmarried Hopi girls wore their hair in the shape of squash blossoms. Men wore loose-fitting cotton trousers and shirts.
Children
When a baby is born a perfect white ear of corn is placed by the baby's head.
Exactly how far away does this thing work? Does it go through walls, etc? I have never tried a wireless network, yeah I know... stuck in a cave!

When can I use my HDs merely by putting them within 1 meter of my comp? Screw those stupid & ugly flat cables, I want a nice, clean and wireless solution for this and I'm pretty sure allot of people with me.
Hate me!
IEEE hasn't even ratified 802.11g yet!
The article is talking about megabits (Mbps), not megabytes (MBps) as mentioned above. Capitalization matters on that acronym.
The time to market for new wireless technology is connected to your personal networking topology exactly how?
Now you can buy cable from this guy that allows communications faster than light! A mere $325.00/1m, what a bargain! (It seems that Mathew Orman figured out where Einstein was wrong. [But don't they all?])
One line blog. I hear that they're called Twitters now.
Just earlier today I bought a FireWire 6-to-6 pins cable to plug two of my PC's back-to-back, since they're otherwise on different VLANs (one on VPN to work ond one directly on the ADSL link for personal stuff). That worked really nicely, and I'm now experiencing the joy of transfering stuff 4x faster than FastEthernet between the two machines. Cost of the cable: 25 EUR.
Originally the term "Ultra Wide Band" designated a special modulation technique but in February 2003 the FCC approved a standard to define UWB-communication as a communication with a minimal 10-dB bandwidth of 20% of the center frequency.
The original modulation scheme associated with UWB works almost as Pulse Position Modulation (PPM): Within a certain, fixed time slot a very short pulse with high energy is emitted. The position of the pulse is decided by a in advance determined code scheme. Depending of the code scheme and the pulse position, the time slot is interpreted as containing either a 0 or a 1.
The powerfull short pulses can be shown to have a very weak and very wide representation in the frequency domain. Without knowing the coding scheme in a link, a UWB signal is thus seen as noise.
Walls and other obstacles tend to obstruct certain specific frequencies only. Since UWB signals have Ultra Wide Bandwith, UWB communication can theroretically go through all kinds of natural obstacles very easily.
The hard part in UWB is making an antenna, that can actually emit signals with this very high bandwidth. Normal antennas are designed to emit in a narrow band. Thus, to make UWB work flawlessly, a lot of research must be made to make a good antenna.

I was all excited when I saw the MBPS. Now I'm only 1/8 as excited.

You all need to sit down in a room and go over the (b)bits and (B)Bytes thing....
The discone antenna is simple to construct and has very wide bandwidth.

TOWELHEADS AND AYATULLAHS ISSUE ANAL FATWAH.
USE THIS FATWAH TO SHOW THE CHRISTIANS AND JEWS OF THE WORLD OUR TRUE CALLING TO BE ANAL FUCKERS.
Kill all niggers. Kill the jews. The jews are in the way of Allah's plan for the world. All people shall bow before Allah and worship him as Muslims do. All people must engage in anal sex at least once a week.
The article seems to suggest it could be out by 2004-05. Thats just about a year and a half to wait.
The speed seems good enuff to replace cables evarywhere you use them. Cables are essentially used when we have short ranges and large data, exactly what this offers.Imagine wireless monitors, external storage and all sorts of reconfigurable computers (imagine a beouwulf cluster which can be reconfigured by just moving machines around and joining a group).

Dear Professor Linux,
How can I keep from soiling my pink underpanties every time I hear wee French referred to as "cheese-eating surrender monkeys"?
Sincerely,

I see MBps (mega Byte per second) and Mbps (Mega bit per second). A byte is 8 bits. That's an order of magnitude of difference!
The standardized way of writing this unit is Mbit/s or MByte/s. Don't invent your own, use the standard units.

Is there really a market for this kind of thing?
Please, name an application where two devices are less than 1 meter apart, need very high-speed communications, and a $0.10 cable can't be used.

Freedom from wires means freedom from climbing into your attic to run cables from the living room to a back bedroom, and punching holes in the ceiling to drop the cable through.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
But gigabit ethernet cards are cheaper than firewire cards, and CAT5 cable is dirt cheap.
Then you can experience "the joy of transfering stuff [10x] faster than FastEthernet between the two machines." Or better than twice as fast as firewire, have the ability to hook up more than two systems to each other, etc.

Check what these guys do.
approved standard for a high-speed, short distance communications standard We now have a standard for a standard? When did that standard pass?
You have have seen discone antennas sold for scanner aficionados, who need a wide frequency range but usually not directionality.
Imagine a cone, pointy side up, with a disc on top. Take one wire to the disk, the other to the cone.
I'm having a devil of a time finding an explanation of the theory that won't collapse under a Slashdotting. One important point is that a frequency range of 3 to 1 or 10 to 1 is considered pretty good for a practical antenna, which might not be enough for a UWB signal.

This is not a WiFi replacement, it's a cable replacement (like Firewire). UWB cannot be used at range, at least partly because it uses very very low power so as not to interfere with the large number of other devices using the variety of frequencies that it covers (which is a huge swathe).
There is some mention by an Intel person that this might become a part of the Bluetooth standard though.

It's like whispering to your nearest neighbor vs a broadcast shout to everyone in the area, and if your neighbor isn't directly wired, he should in turn route your message further along an overlapping mesh of other wireless nodes.

Your security guy would kill you if he heard that. By bridging your unsecured PC to your VPN'd pc you have opened a door that crackers can use to get into your corporate network. The whole point of a VPN is to have a secured connection between your pc and the corporate lan that can't be used by outside sources.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
For the price of a GbE card, you can get a 4-6 port FW card. Use one machine as a router/server, and you have 5-7 machines at FW speeds. To do that with GbE you'd need a Gb switch, which ain't cheap.
Multiport FireWire cards have all the ports on the same bus, so in that scenario all the machines would share the 400Mbps.

You don't need a switch for gigabit over copper. Assuming the total wiring length is less than 50 meters, all you need is some CAT-5 splitters, which should cost less than a single firewire cable does.

Wow! That's the first time I've heard someone claim that! My experience is quite the opposite (here in the U.S.)... If you want firewire in your new system, you either have to buy the card yourself, or shop around until you find the few systems that come with firewire, and pay significantly more for the feature.
