Bluetooth 3.0 Red-Lines Transfer Rates

Tokyo — Next-generation Bluetooth technology, which will accelerate peak transfer speeds to 24Mbps from the current 3Mbps, will be available in consumer products in nine to 12 months, the Bluetooth special interest group (SIG) said in adopting the new spec.

The Bluetooth Core Specification Version 3.0 + High Speed (HS), also called Bluetooth 3.0, will enable bulk

synchronization of music libraries between PC and music player or phone, bulk downloads of pictures from a phone to a printer or PC, and speedier transfers of video files from camera or phone to computer or television, the group said. In mobile devices, 3.0 technology will reduce power consumption because of enhanced power control is built in, the group added.

Products incorporating Bluetooth 3.0, based on the IEEE 802.11 radio protocol, will be backward-compatible with products incorporating earlier Bluetooth versions. Like the current Bluetooth 2.1 + EDR version, the new version includes Simple Secure Pairing and built-in, automatic security.

“Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers,” said SIG executive director Michael Foley. “Members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN [personal area network].”

Compared with other wireless technologies, Bluetooth 3.0 is more than twice as fast as the first wireless area network technology, IEEE 802.11b Wi-Fi, but slower than 802.11a/g.
