Wireless USB
Overview
Wireless USB
is a short-range, high-bandwidth wireless extension to USB that combines
the speed and ease-of-use of USB 2.0 with the convenience of wireless technology.
Wireless USB
is sometimes abbreviated as "WUSB", although the USB Implementers Forum
discourages this practice and instead prefers to call the technology
"Certified Wireless USB" to differentiate it from competitors.
Wireless USB
is based on the common radio platform,
which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters.
It was designed to operate in the 3.1 to 10.6 GHz frequency range, although local regulatory policies
may restrict the legal operating range for any given country.
Spec
Wireless USB technology offers a solution for high bandwidth, low cost, low power consumption, and physical size
requirements of next-generation consumer electronic devices.
- Certified Wireless USB
is the first high-speed wireless personal interconnect
technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices.
- Certified Wireless USB
will preserve the functionality of wired USB while also
unwiring the cable connection and providing enhanced support for streaming media CE devices and peripherals.
- Certified Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.
Implementation
Wireless USB
(WUSB) personal connectivity will bring the convenience and mobility of wireless
communications to high-speed interconnects for multimedia consumer electronics, PC peripherals
and mobile devices.
With a targeted bandwidth of 480 Mbps, WUSB will feature wireless highdata
throughput with low power consumption for distances less than 10 meters.
The WUSB
interface will deliver the benefits of high-speed wireless connectivity, increased
security, ease-of-use and backward compatibility to customers.
The WUSB
promoters, consisting of Agere Systems, HP, Microsoft, NEC Corporation,
Philips Electronics and Samsung, are committed to preserving the existing USB devices, class
driver infrastructure and investment, look-and-feel and ease-of-use of wired USB. WUSB will
maintain the same scalable device performance and capability while also addressing new
consumer electronics requirements.
The first Wireless USB
implementations will be in the form of discrete silicon that will be
introduced in a number of form factors. These include add-in cards and dongles along with
embedded solutions to support the technology’s introduction and subsequent rapid ramp-up. New
adopter members are welcome to join this group. For more information, visit
