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 15 May, according to an Intel spokesperson.

The Wireless USB specification provides for a data transfer speed of 480Mbps (megabits per second) over distances of about 3 yards, and it will work at lower speeds up to a distance of about 11 yards.

A candidate Version 1.0 specification was sent to the Wireless USB Promoter Group on 1 April for a 45-day review.

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

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

NEC expects to have its first products on sale in Japan during the first half of 2006. Intel is planning to boost Wireless USB's transfer speed to 1Gbps by the end of the decade.
