With Notebooks and Netbooks start to come out with Bluetooth 3.0 I am taking this opportunity to recap what it is all about from a collection of links on the net.

April 2009 ...

Bluetooth changed the mobile tech game by allowing us to wirelessly field calls and stream data, but now the latest version will let us move even more data at dramactically faster rate–up to 24 Mbps (the current spec maxes out at 3 Mbps). How is this possible? By partnering the Bluetooth radio with the 802.11 radio–the same 802.11 radio found in our notebooks, portable media players, and phones.

Bluetooth 3.0 + HS will allow users to move large data files (music, video, photos) between a notebook and phone, camera to television, and any other 3.0+HS pairing. So, instead of sending a single image between items, you can move entire libraries.

The Bluetooth SIG states that Bluetooth 3.0 + HS’ Enhanced Power Control will reduce the number of disconnects caused by movement (such as placing a phone into a pockt or purse), and the new protocol will offer increased power savings. In addition, Bluetooth 3.0 builds upon the solid foundation of Bluetooth 2.1+EDR (such as Simple Secure Pairing and security), so it’ll be backward compatible with that signal.

Atheros, Broadcom, CDR, and Marvell have already signed on to build Bluetooth 3.0 + HS chipsets, and products are expected to hit the market within 9 to 12 months.



February 2010 ...

"Key features of the new Bluetooth v3.0 + HS standard include:

o 10 times the transmission speed over previous Bluetooth specifications.

o Expanded capabilities for remote control applications featuring Unicast Connectionless Data (UCD) functionality that enables low power operation and reduced latency for CE remote control applications.

o Enhanced powerful security capabilities with support forthe new Read Encryption Key Size feature that allows Bluetooth applications to ensure an appropriate level of communications security.

o Bluetooth v3.0 + HS is currently shipping in PCs and smartphones. The InConcert Maestro platform that allows application developers to exploit the high speed function in novel ways is available to early access-partners."

SuperSpeed USB seems to be the hot transfer protocol these days, mostly because the coming out parties at IDF and CES went over really well. Tons of companies are voicing their support for the next-generation USB solution, and it should only be a few more months before we see a number of machine shipping with USB 3.0. But a protocol that many seemed to have forgotten about is Bluetooth 3.0.

We get the feeling that it will be brought back to our attention in a big way at Mobile World Congress, which starts in just a few weeks in Spain. Many new cellphone and mobile technologies are expected to be showcased, and Broadcom is a huge player in the mobile space. What's so special, you ask? Broadcom has just announced a huge, sweeping support effort for the next generation of Bluetooth, which promises to hasten transfers between short-range devices. The company has just announced that Bluetooth 3.0 + HD specification has been adopted in their Bluetooth and InConcert combo chips/modules, which means that a whole slew of mobile devices will soon be able to transfer files across short distances at speeds of up to 24Mbps.

Best of all, it's now in production with ODM partners in a mini-PCIe combo module for notebook computers and a combo single chip based SIP module targeting smartphones. To us, that sounds as if BT 3.0 could even make its way over to laptops and netbooks in the short term, which would definitely open up the transfer capabilities. Bluetooth 3.0, USB 3.0 and Intel's Wireless Display Technology could make for a wicked trio--even the promise of these will make it awfully tough to buy into a machine now knowing what is just across the horizon.
