Bluetooth 3.0 Networking
Bluetooth 3.0 specification provides increased data transfer speeds of up to 24MBps...
The Bluetooth 3.0 spec is ready to hit the streets, The updated specification will enable the transfer of larger files thanks to the incorporation of 802.11n.
Bluetooth 3.0 hit the streets as predicted on April 21st, and although the specification is missing the anticipated ultrawideband (UWB), data transfers have been increased by the incorporation of 802.11 technology.
Using the 802.11 technology, Bluetooth 3.0 will be able to handle much larger data transfers with dramatically improved file transfer speeds.
The previous spec was great for transferring smaller files like contact info and calender items, but as mobile devices become more like media centers, speed and connectivity improvements come much needed.
The previous Bluetooth 2.1 + EDR spec offer maximum data transfer speeds of around 3MB, by switching seamlessly to use 802.11n wireless, the new version of the technology provides around 24MB. The new spec is also more efficient that previous versions, ushering in a new era in short range data transferring.
The Bluetooth Special Interest Group (SIG) said in a statement on Wednesday:
Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers — members get more function out of the two radios they are already including in devices, and consumers with Bluetooth [3.0] products will get faster exchange of information without changing how they connect.”
The Bluetooth 3.0 + High Speed specification works by using two compatible Bluetooth modules that coordinate a switch to 802.11. When the transferring large files, the 802.11n kicks in, and connection is managed over Bluetooth, no actual wireless network is necessary – the switch will appear seamless to the user.
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.
The new specification is, however, missing ultrawideband (UWB) feature that would have taken its transfer speeds to around 480Mbps. Gartner vice president and analyst Nick Jones said on Wednesday that UWB was left out of Bluetooth 3.0 due to technical problems.
“I believe there were issues of getting [UWB] to work as well as people had expected, it would have been nice to have multiple-hundreds-of-megabits-per-second data transfers, but the lack of it is an inconvenience, not a disaster. UWB has a relatively small range, so once you get more than a few meters away you don’t get the hundreds of megabits anyway.”
According to the statement released by the Bluetooth SIG, consumer products using Bluetooth 3.0 are expected to hit shelves in from nine to 12 months’ time. These products are likely to include PCs, mobile phones, digital cameras and camcorders.
