Bluetooth 3.0 specification is ready, on the streets, in an amendment to the specification makes it possible to transfer large files, thanks to the integration of 802.11n.

Bluetooth 3.0 on the road, as expected, 21 April, and even if the specification is not available for ultrawideband (UWB), the data was increased by the addition of 802.11 technology.

Using technology 802.11, Bluetooth 3.0, can be much larger data transfers with significantly improved speed of file transfer.

First, a large bandwidth to transfer small files such as contacts and calendar entries, but more and more mobile devices like Media Center, connection speed and a very necessary improvement.

Currently, the specification Bluetooth 2.1 + EDR offers maximum data transfer rate is about 3 MB, the most seamless wireless 802.11n, the new version of the technology about 24 MB. The new specification is also more efficient than previous versions, opens a new era in the field of data transmission with short-range.

In the Bluetooth Special Interest Group (SIG), said in his speech on Wednesday:

The use of radio-802.11 is a natural choice, since he proposes to increase the effectiveness of our members, and consumers – more members of the two radio stations that are already in these devices, as well as consumers with Bluetooth [3.0] to get faster exchange of information, while not changing the way we connected.

In the specifications of Bluetooth 3.0 + High speed through the use of two compatible Bluetooth module to coordinate the transition to 802.11. If you send large files, 802.11n feet and is controlled via a connection Bluetooth, a wireless network is not necessary – for a smooth transition to the user.

Once the file is transferred, the mechanisms for coordinating the return to slow and backward-compatible 3.0Mbps previous version of Bluetooth, which consumes less power and bandwidth.

The new specification, but the lack of ultrawideband (UWB), which is a typical speed of about 480 Mbps. Vice President and Gartner analyst Nick Jones said on Wednesday that it was not for UWB Bluetooth 3.0, due to technical problems.

“There are issues I think the first [UWB] to work, because people expected it would be nice if a few hundred megabits per second data transfer, but his absence is a disadvantage, but not a disaster. UWB has a relatively small area, so if you have a few meters you do not have the hundreds of megabits in any case.

According to the Bluetooth SIG, consumer goods via Bluetooth 3.0, which is expected to be on the shelves to nine months, 12 hours. These products are also computers, mobile phones, digital cameras and camcorders.
