Bluetooth 3.0 prepped for launch on April 21

Bluetooth logoThe Bluetooth 3.0 spec is ready to hit the streets, with the Bluetooth SIG preparing for an official release later this month. The updated specification will enable the transfer of larger files thanks to the incorporation of 802.11n.

Right on schedule, the Bluetooth Special Interest Group is preparing to launch the Bluetooth 3.0 specification on April 21. A list of chip-makers who are on board with the updated spec has not yet been made public, but it's expected to be available when the formal announcement is made later this month.

Bluetooth 3.0 will bring with it dramatically-improved file transfer speeds by using 802.11 technology (not technically WiFi, which is a certified version of 802.11 standards) that will enable the transfer of much larger files. The previous spec was fine for the transfer of more bite-sized data, like contact info or calendar items, but as mobile devices evolve to become our entertainment centers on-the-go, a speed improvement will certainly be helpful for transferring things like video and music collections.

For those curious, the Bluetooth 3.0 + High Speed standard works by using two compatible Bluetooth modules that coordinate a switch to 802.11 (without having to join a WiFi network) to move the bulk files. Once a file-transfer is complete, the devices coordinate a switch back to the slower and backwards-compatible 3.0Mbps rate of earlier Bluetooth releases, which consumes less power and bandwidth.

Once the new standard is announced by the Bluetooth SIG, it likely won't be long before we see devices with Bluetooth 3.0 built-in. Of course, when you have battery-sucking phones like the iPhone that need to be plugged in and synced every day already, there seems like less of a need for such high-speed file transfers, but everyone else using Bluetooth to sync files will no doubt be happy with the improvements.
