Version 1.0 of the Wireless USB specification, which is being promoted as the successor to the USB data transfer method between electronics devices, should be approved by mid-May, Intel said last week.

The Wireless USB specification is for 480Mbps transfer speed over distances of about three meters and it will work at lower speeds up to a distance of about 10 metres.

A candidate Version 1.0 specification was sent to the Wireless USB Promoter Group on April 1 for a 45 day review, said Jeff Ravencraft, technology strategist for Intel's Communications Technology Lab, at a press event during the Intel Developer Forum (IDF) Japan 2005, on Friday.

"The new news is...we'll have the specification finalized on or about May 15," he said.

Version 1.0 of any technology is a key specification that enables developers to start product design. The Wireless USB Promoter Group, which is authorizing the specification, consists of Agere, HP, Microsoft, NEC, Philips, Samsung, and Intel.

Consumers can look forward to a handful of Wireless USB products appearing in shops in the US by the end of this year, with many more products following in the first half of 2006, Ravencraft said.

NEC Electronics expects to have its first products on sale in Japan during the first half of 2006, according to Yoshiyuki Tomoda, senior manager at the company's PC Peripheral Systems Division.

Intel is planning to boost Wireless USB's transfer speed to 1Gbps before the end of the decade, said Brad Hosler, Wireless USB architect at Intel's Communications Technology Lab.
