An Introduction To Wireless USB (WUSB)

Posted by timothy on from the not-too-technical dept.

An anonymous reader writes "This technical whitepaper by Rafael Kolic, a technology marketing manager in Intel's Corporate Technology Group, introduces Wireless USB (WUSB) and explains how it will impact device performance and mobility. The latest iteration of USB technology, WUSB will offer the same functionality as standard wired USB devices -- but without the cabling."

  1. Interesting concept... by Gleenie · · Score: 0, Redundant

    Wow, you'd think someone would have come up with that already... But wait, I think they did - it's called "Bluetooth".

    Apart from the higher bandwidth I don't see anything in this article that isn't already possible with Bluetooth. And if you _really_ need higher bandwidth then there's 802.11.

    Other than the "not invented here" factor, I can't imagine why Intel wants to invent aome new standard to do the same job as an existing one. Especially since that other one has taken 5 years to start catching on, and is now getting pretty popular. How long would it take for this one to do the same?

    These things are going to eat several times more power than a Bluetooth radio. The article says:
    "The power target for WUSB radio will be introduced at less than 300 mW and drive to a target of 100 mW over time."


    That's the same as lower power 802.11 cards


    Bluetooth chips generally eat less than 40mW, some as little
    as 20mW. I wouldn't put WUSB in a cell-phone, or my keyboard.
