890Mbps Ultra-WidebandThink that'll handle your HD home networking needs, grandma? ( old news - 12:28PM Thursday Dec 13 2007) tags: business · wireless · hardware · bandwidth · cableUltra-Wideband (UWB) is a radio modulation technique noted for its potential to offer blazing speeds at very short ranges (great for in-home HD distribution over wireless or coaxial). Unfortunately UWB has been bogged down in a standards war for many years. A company named Pulse~LINK has been working on UWB hardware for some time, and recently conducted tests showing their gear may be able to achieve wireless speeds between 500 and 890Mbps: A comprehensive test of UWB products, conducted by octoScope, showed CWave's 1.35 Gbps over-the-air signaling rate delivering 890 Mbps application layer throughput. CWave performance was 15 to 20 times greater than all other wireless UWB products measured in the test, the best of which peaked at around 50 Mbps at close range. A full report was published here (pdf) by EETimes, who offer an additional explanation here: An innovative aspect of the CWave architecture is that any device using the Pulse-Link chipset is capable of supporting wireless, coaxial and power-line transmissions under a single 802.15.3b MAC, enabling HD video transport throughout the entire house on whatever media are available. The isochronous 802.15.3b MAC, with QoS built-in from the ground up, is designed to support whole-home networking of streaming video, multi-channel audio and high data rate networking. Pulse~LINK has also tinkered with taking this idea outside of the home and onto cable networks. They had hoped to increase the bandwidth available to cable providers (to the tune of +1 gigabit downstream, 580 megabits upstream per node). We've not heard of any cable operators signing on to the idea, however. Update: The president of Pulse~LINK stops by our comment section to explain why exactly UWB is a big deal: Today, you can network your PC's. Why not your DVD players, game consoles, High Definition TVs, and the rest? Wouldn't you like to connect those things, but get rid of the rat's nest of wires at the same time.
It takes about 20Mbps to network a High Definition 1080i stream, about 35Mbps at 1080p. If you want trick play (pause, fast forward, rewind), multiply those data rates by four. If you have several rooms and different people watching different programs in different rooms, the data rate requirement goes up from there.

| Re: That's fast... said by OlivierDT  :Another technology that we'll never see But damn... that's fast! Yes it is fast and yet it is yet another great intervention that you can buy some day but won't do you any good unless your exchanging files between 2 computers in your own house.
Because the ISP's wont be offering speeds like that for quite some time for a reasonable rate.
So should they be spending time making things for the future or concentrating on making ISP's raise the bar, giving higher speeds to customers so they can take advantage of there high speed products.
Like 802.11 G standard or N standard who can really take advantage of those kinds of speeds?
Only a home network, you cant download 54mbs or 100mbs on the internet without paying an arm and a leg for a DS3 or OC3.
Whats the motivation. Just like saying buy cat 6 cable its faster than cat5 , but yet cat5 is more than you need its capable of 100mbs.
Whats the motivation?
Great ideas and nice to see technology.
But would be nicer to see providers catch up to it.
otherwise i am happy with a 802.11 B wireless device because that's about as fast as I can connect to the internet and B standard goes farther than G and is more reliable. | |

| Re: That's fast... It's not about connecting two PCs or forwarding data from your ISP. It's about networking the high-definition centric multimedia appliances around your home.
For example, wouldn't it be nice to eliminate the HDMI cable. Or, come out of the HDMI port on your new Blu-Ray or HD-DVD player and being able to enjoy that device from every single HDTV in your home without connecting any new wires between anything.
Today, you can network your PC's. Why not your DVD players, game consoles, High Definition TVs, and the rest? Wouldn't you like to connect those things, but get rid of the rat's nest of wires at the same time.

If you have several rooms and different people watching different programs in different rooms, the data rate requirement goes up from there.
It also takes guaranteed Quality of Service, otherwise our video image breaks up and the video is not synchronized with the Audio. WiFi, Ethernet, etc., do not offer guaranteed quality of service - that's the primary reason you don't use them for networking high quality video.
So, it isn't about your ISP and browsing the internet or checking emails. It's about your entertainment content service provider if you use a personal video recorder in the set top box and want to network your recorded content around the home. And, its about networking all of your DVD's, etc., so that content - protected or personal - located anywhere in your house can be accessed and enjoyed from any suitable HDTV in your house without you having to run new wires or move your appliances
Sound like you might want that? | |

| Re: That's fast... Me too. I have yet to find anything wireless that's truly reliable. Wireless is really convenient but even the stuff I have that works best seems to suffer from some level of intermittent brain-fartiness.
Microsoft wireless keyboard and mouse? LOL. I have to have the receiver less than a foot away from the mouse. Even then I *still* get sporadic "Wireless signal quality is low" messages. The Bluetooth mouse on my mac pro seems to be a much better situation. In fact I think Bluetooth is the only wireless technology I've used that really works well in its specified signal range (although its not without its own share of issues).
Wifi networking. All the 802.11b gear I tried was a joke, always disconnecting and reconnecting. "g" gear seems to have improved the situation dramatiacally, but speeds are still about a third of what's advertised, and the connections suffer from latency spikes. When I've run into crap connections, bigger antennas rarely does any good. The only way for me to use my laptop comfortably was to move an access point into the same room.
In my theater room I had to buy a keyboard rated at 100 feet just to use it about 10 feet away. And even then the damn thing drops characters.
I tried a IOGear wireless "UWB" USB hub. The stupid thing didn't work just 6 feet away, line of sight. . I ended up returning it and purchasing a far more complex, far slower, but more functioning combination of a Belkin Network USB hub and a Buffalo router in client mode.
The thought of HDTV fed wirelessly gives me the hebejebes. With my luck, I can virtually guarantee it would intermittently stop and freeze. Not all the time, but just enough to remind me that wireless will never be as good as a hardwired connection. | |

Seriously, if you're having that much trouble with all these wireless devices in your house, it's your house. There's some flaky gear out there for sure, but there's also a lot that just plain works. | |

@silkroadtech.com | Guess you have no use for file servers, media hubs etc.
I max out my 100mbs internal network daily.
Once I update the desktops I plan on going to 1000Mbps ethernet.
Having those speeds locally and being wireless would be awesome | |

| Verizon Fios is surpassing those requirements to transfer video from stb to stb for the Multiroom dvr option, as well as providing video on demand on a wired network. With the multiroom option you can watch from three other stb and have the dvr record two things at once and be able to watch something you have previously recorded at the same time. Thats 6 things at one time the dvr is doing without missing a beat. Coming this next year High Definition will be part of the Multiroom option and of the Video on demand. Verizon is the leader in this technology. | |

| Re: Wireless Home Theater said by MattE :This would be great for alleviating the rat's nest of wires around almost all electronic devices ... I wonder if the range would be great enough to replace WiFi as the streaming transport from a PC to a media center extender? There is items out there that use wireless technology to your home thearter already. You just have to search for them.
My fear is your going to have so many wireless devices your going to run into each other at some point or you will have to take precausions to make sure all your devices don't use the same frequency or your neighbors.
otherwise your better off with a wired device for 2 reasons 1. no interference.
2. no chemo therapy effect (microwave radiation house effect) | |

| said by MattE :... I wonder if the range would be great enough to replace WiFi as the streaming transport from a PC to a media center extender? Sure. With the bandwidth to burn they would mesh great. Every device would become a micro node. Wired to the 3rd hop is still 225 Mbps. 55 Mbps at 6 hops is still enough for a few HD channels simultaneous, and some fast ast internet. I would think there to be a natural market for the elimination of signal wires, and UWB has the jizm to do the job. | |

| Re: Wireless Home Theater Now if we could only get the movie industry to "allow" us to legally (and easily) move our DVD content from the discs to computers. (By "allow" I mean consumer grade software or devices that don't get sued out of existence by the MPAA.)
Imagine bringing home a new DVD and putting it into your Home Video Server. The HVS rips your DVD to a file and shares it (video, menus, extras and all) with any TV in that home that has a Wireless Home Video Receiver connected to it.
Right now I rarely buy DVDs because they get watched once and then wind up sitting on the shelf in unorganized stacks. It would be much better to be able to put the movie into some sort of home On-Demand system. Unfortunately, the movie industry is so busy worrying about the five people that would pirate the movies to see the income potential of the five hundred who would buy and watch more movies.
