Wireless USB 1.1 under development

Posted on Thursday, September 20 2007 @ 19:14:20 CEST by

EE Times writes Wireless USB 1.1 is under development and is expected to be more than twice as fast:
The wireless USB initiative announced today its targets for a version 1.1 of its specification. The new version raises throughput targets from 480 Mbits/second to 1 Gbit/second over three meters.

Katagiri of NEC said the throughput targets are a stretch because most companies are still shipping first-generation wireless USB devices only hitting rates of 40 Mbits/second.

"We have to make the protocol more efficient," Katagiri said. "If we go for a Gbit we will need to deliver at least 500 Mbits/s," he added.

The 1.1 spec will support band groups at 6 GHz and above in addition to the 3-4 GHz bands supported by wireless USB 1.0. It aims to lower power consumption by an undisclosed amount. It also will adopt the techniques of near-field communications for letting two devices identify themselves to each other with a simple contact.
