The Wireless USB Promoter Group has started developing the next version of the Wireless USB specification, dubbed 1.1, that will build on the existing 1.0 standard.

Specification enhancements include further options for first-time association of devices, improved power efficiency, and support for UWB frequencies above 6GHz.

The promoters groupwhich includes NXP Semiconductors, HP, Intel Corp., LSI Corp., Microsoft Corp., Samsung Electronics and NEC Electronicsannounced the work at the Wireless USB Developers Conference held Monday (Oct.1) in Amsterdam, the Netherlands.

The latest version should be finalized during the first half of 2008.

Also at the Conference, NXP revealed it is working with Japanese module maker Murata on a USB module measuring less than 1.5cm? based on its wireless USB controller, ISP3582, the first to receive official certification to the 1.0 specification by the Implementers Forum.

NXP's device combines a Registered PHY from Realtek which has been verified as compliant to the WiMedia PHY specification. The chip is capable of handling data rates at 480Mbps.

Wireless USB is based on the WiMedia Alliance Ultrawideband Common Radio Platform.

At the event, NXP demonstrated a Wireless USB native module that incorporates its Wireless USB native device controller.

"It's great to see a certified solution become available to end manufacturers that is ideal for the ultra small peripherals being introduced in the marketplace," said Jeff Ravencraft, president of the USB-IF.

The venture with Murata is targeted at portable products such as mobile phones, digital cameras, MP3 and personal media players. It will be a Low Temperature Co-fired Ceramic (LTCC) package that can be readily placed in systems easing RF design consideration and shortening time to market, and is scheduled to be sampling in Q1 2008.
