The Wireless USB Promoter Group has announced the completion of the Wireless USB specification. The specification will now transition to the USB Implementers Forum (USB-IF) to undertake certification, compliance testing, logo licensing and marketing for Wireless USB.
According to the group, the Wireless USB is the first high-speed wireless personal interconnect technology that combines the freedom and flexibility of wireless technology with the ease-of-use, speed and security of wired USB. Wireless USB delivers the requirements for PC, CE and mobile usage models while preserving and extending the investment in the existing USB infrastructure. It will provide backward compatibility and seamless legacy support through the definition of external adapters, which will help ensure quick proliferation.
Wireless USB is based on the WiMedia MAC Convergence Architecture, utilizing the WiMedia Alliance's MB-OFDM ultra wideband MAC and PHY. It has been designed to coexist with the other upper-layer protocols built atop WiMedia's common radio platform. It delivers speeds equivalent to wired Hi-Speed USB, with bandwidth of 480Mb/s at 3 meters and 110Mb/s at 10 meters. Wireless USB will maintain the same scalable device performance and capability while also addressing new consumer electronics requirements.
The Wireless USB Promoter Group, consists of seven companies: Agere Systems, Hewlett Packard, Intel, Microsoft, NEC, Philips Semiconductors and Samsung. This group has defined the Wireless USB specification with the support of more than 100 contributor members. The group has now transitioned the specification's management to the USB-IF, the governing body of USB specifications.
