Certified Wireless USB technology from the USB-IF is an extension to the current USB 2.0 standard.
It delivers data transfer rates up to 480Mbit/s, comparable to wired USB 2.0 connections, with a maximum wireless communications range of up to 10m.
Unwiring the cable connection frees users from having to make cumbersome and unsightly wired connections to enjoy high-speed data access and allows users to connect their devices freely wherever they want to use them.
Certified Wireless USB technology will make it possible to expand the range of applications for computers and digital entertainment devices and encourage the discovery of new ways 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 and other industry leaders, NEC Electronics is a core member of the USB-IF, which developed and supports the USB specification.
Since launching volume production of USB 2.0 devices in 2000, NEC Electronics has shipped 100 million-plus units.
Samples of NEC Electronics' uPD720170 and uPD720180 Wireless USB devices are available now starting at US $20 each in sample quantities.
