    NEC Electronics today expanded its suite of Wireless USB devices with the introduction of the µPD720171 Wireless USB host controller. Building on the company's first host controller (part number µPD720170), the new µPD720171 controller for PCI Express bus interfaces, enables high-speed, wireless data transmission between PCs that have MiniCard or Half-Minicard expansion cards and PC peripheral devices such as wireless hubs, printers, external storage equipment and digital cameras. The new host controller also provides laptop computer connectivity through an ExpressCard slot. Providing greater throughput and higher performance than previous host devices, the µPD720171 controller enables consumers to enjoy wireless lifestyles while maintaining wired USB functionality and ease of use.


    "As the consumer appetite for wireless connectivity increases, the industry is requiring reliable, standardized interface solutions that can transmit data at speeds equivalent to wired USB connections," said Yoshiyuki Tomoda, Group Manager, SoC Systems Division, NEC Electronics Corporation. "By providing these performance levels, our new µPD720171 host controller is helping bring the industry closer to mainstream adoption of advanced wireless technologies."

    Certified by the USB Implementers Forum (USB-IF), the µPD720171 controller conforms to the Wireless USB 1.0 specification and also to the Wireless Host Controller Interface (WHCI) specification developed by Intel with support from Microsoft, NEC Corporation, Philips, Texas Instruments and other experts in Wireless USB technology.

    Capabilities of Wireless USB
    Developed by the USB-IF, Wireless USB technology is an extension of the current USB 2.0 standard, which has been hailed as the next-generation interface standard for computers and multimedia consumer electronics devices. Products based on Wireless USB technology can transfer up to 480 megabits per second (Mbps) of data, comparable to wired USB 2.0 connections, within a maximum range of 10 meters. NEC Electronics' new controller can transfer up to 480 Mbps within a maximum range of three meters.
    Unwiring the cable connection frees users from having to make cumbersome and unsightly wired connections and enables them to enjoy high-speed data access wherever wireless connectivity is possible. Wireless USB technology is currently making it possible for designers to expand the boundaries of computing and digital entertainment to discover new ways for consumers to enjoy digital media.

    NEC Electronics has played a central role in making the current USB 2.0 standard one of the most successful interfaces in the history of personal computing. Along with Intel Corporation and other industry leaders, NEC Electronics is a core member of the USB-IF, which developed the USB and USB 2.0 specifications and is currently developing the USB 3.0 specification. Since launching volume production of USB 2.0 devices in 2000, NEC Electronics has shipped an industry-leading 150 million units worldwide.

    Pricing and Availability
    Samples of NEC Electronics' µPD720171 Wireless USB host controller are available now at US$10.00 each (pricing and availability are subject to change). Reference boards are also available upon request. More information about NEC Electronics' lineup of Wireless USB solutions can be found at http://www.necel.com/cwusb/en/newproducts.html.

    Although a great concept... nearly all USB devices I use need a power supply. So we drop the USB cable to go wireless, but then need to add a power supply, e.g. keyboard, iPod, mobile phone, VoiP handset, etc.

    Any device that has a PSU, IMO, is better connected on TCP/IP than wireless USB, e.g. printer, scanner, external HDD.

    Nonetheless, I'm sure there are lots of applications.

    I hope it wont be as buggy and security problematic as bluetooth though. PS. Always hated bluetooth. Lets hope wireless USB kills it once and for all.

    apart from my printer (Laserprinter with USB) none of my USB Devices need external powersupply, even my scanner runs of usb power.
    It would make no sense when it comes to USB devices with no battery inside, the passive one's even if they use the usb power when they are connected

    Build a wireless usb mini-pci x card with wifi ndraft on it and sell it as upgrade for older Notebook that would rock :D and a small reciver wicht converts normal usb singnal to wireless in the size of a usb plug! that would make any usb drive upgradeble (wich is Battery powered ;) )

    Is it safe? like we use w-lan WPA2 and not WEP any more, is there anything with encryption?

    That is very cool. Soon we have ourselves wirelessly transfered monitors in the future if USB prevails over Firewire's return.
