Today at the Wireless USB Conference in San Jose California, Wireless USB 1.0 which is based on the WiMedia MAC Convergence Architecture was approved.

“As the developer of the ultra wideband technical specifications, the WiMedia Alliance will work together with the USB-IF to advance the industry toward rapid consumer adoption of the Wireless USB technology,” Kursat Kimyacioglu, vice president of the WiMedia Alliance told The NewsFactor.

At the conference, Alereon showed off a prototype that could transmit data at 480 megabits per second. I chatted with the company CEO Eric Broockman, and got the lowdown from him. I also learnt the man maintains a weblog, Life Without Wires.

Here are excerpts from that little chat….

OM: Eric, can you bring us up to speed on what is Ultra wideband? It gets a tad confusing, because UWB is used in context of many different applications.
Eric Broockman: It is easy to get confused. In short, UWB is any radio transmission that is 500 megahertz wide. Just like you have many flavors of broadcast radio – AM, FM and Satellite, you have many different forms of UWB.

UWB uses the 3.1 GHz to 10.6 GHz part of the wireless spectrum. FCC has so far approved 3.1 to 4.7 GHz for UWB in three swathes of 528 MHz. Right now US is the only country where UWB is legal but we are hopeful that by end of the year few more large economies will come online as well.

wireless landscape

OM: As a consumer, why should I really care? What does wireless USB do for me?
EB: Well it’s about convenience really. Consumers can connect cameras to printers without worrying about cables. There are many such applications.

OM: I have heard that is going to be used a way to stream video inside the home, and connecting say DVD players with flat screen televisions?
EB: We don’t think that really is the killer application for wireless USB. Its more of a cable replacement technology, and that’s a big enough market. I think for streaming video, the industry will gravitate towards 802.11n.

OM: When can we expect to see the products actually come to market?
EB: We expect production chips in the third quarter, and by early Christmas you can expect some products to come to market. It would be safe to say that 2006 is going to be breakthrough year for wireless USB.

OM: Any more details you can offer?
EB: I think the initial products will come in the dongle/adapter form factors, but very quickly they will go under the hood.

  1. A few comments. First off, how do they expect to sell 6 million UWB units when we are nearly halfway into Y2005? Have they looked at the rampup numbers for Bluetooth?

    Wireless USB sounds great but I have to wonder whats going to happen when the hackers get a hold of the devices. Remember when WEP was cracked and shown flawed? Now imagine a similar scenario for WUSB. It will be interesting to see how it plays out.

  2. Intel, Alereon Show 480 Mbps Integrated UWB

    With a MAC from Intel and a PHY from Alereon, 480 Mbps UWB is shown: The two companies have collaborated on this demonstration, showing high-speed ultrawideband. The MAC (Media Access Controller) is the network side; the PHY (for physical layer), the …

  3. 802.11n and Wireless USB

    Technologies such as Wireless USB and 802.11n could allow us to control multiple displays from a single computer, lowering the total hardware cost of retail kiosk and signage deployments.

  4. All About Wireless USB

    Hey! Are you coming apart at the seams to learn all you can about wireless USB? Then perhaps you should take a couple of minutes and allow this article to get you up to speed….

  5. I do agree, the hacking aspect of it is quite troubling. i don’t know the details myself because i have not had a chance to read the spec in details. the pdf is linked but will put this one on the back burner to be honest.

  6. What about power? Will all our wireless USB devices need batteries?

  7. Good post…did he have anything to say regarding Bluetooth, especially in its next incarnation?

  8. They have lowered the power requirements enough that the dongles will work. so no batteries required for wireless usb purposes.

    michael,

    he did point out that the two technologies, bluetooth and wusb will co exist. for instance bluetooth can do audio, while wusb cannot do that among a couple of other things

  9. Don’t understand: how is UWB a “cable-replacement technology”, but not for connecting, say, DVD players to screens. Does this mean emphatically no streaming media?

    apparently there are some start-ups which are attempting to do video-over-wusb using their own properitary chips but even they are thinking about connecting monitors to pcs to begin with. i think the QoS of HDvideo means that it will be a while before the video signals can be sent over wusb
