Gauging the Wibree wave

My colleague in London, John Walko, has a good update today on progress on Wibree, a low power variant of Bluetooth promoted by Nokia. Although backers have been fairly quiet since their launch in October, the group is close to launching a final spec that will detail its physical layer and releasing news of perhaps a half dozen new backers. What's more chip designs are being tested now and should be ready to sample before the end of the year, according to the report.

Companies including Dell have complained that Wibree will further fragment an already highly niched personal area network sector. But Wibree backers insist they will complement not compete with Bluetooth.

Wibree aims to use the same basic radio design as Bluetooth, but require a fraction of the power thanks to an approach that keeps transceivers in a sleep mode except for short burst of communications at up to 1 Mbit/s over 5-10 meters. Their aim is to let devices like connected watches and toys operate for a year on their batteries.
