Ultra-low-power Bluetooth on the way

8 replies · 2,647 views · Started 25 April 2010

The Bluetooth SIG has announced that the 'much anticipated' v4.0 update to the Bluetooth protocol (incorporating the Bluetooth low energy technology pioneered by Nokia in Wibree) will be finalized and sent to manufacturers by the end of June. Bluetooth 4.0 could theoretically be powered for years by a coin-celled battery, has faster transfer rates, and has an increased range that can extend up to 200 feet and beyond (at higher power, obviously). Bluetooth v4.0-enabled devices should come on sale around the end of 2010.

Read on in the full article.

So this is the only kind of innovation Nokia is capable of nowadays? Where are my animated wallpapers?!?!? I want.. no, I NEED them now!

I thought developing bluetooth standards was not primarily Nokia's responsibility. In fact if you read properly, the article also starts with "Bluetooth SIG has announced". Nokia just took the lead in developing a new version and also demonstrated the new version of bluetooth on one of their handsets. Plus if they can add something that can actually consume less energy in our otherwise current power hungry handsets, whats wrong with that?

It seems that people just keep waiting to take a shot at Nokia...

One thing I am curious about though. The article says that v4.0 has been announced and will be implemented soon. The last bluetooth version I know of is v2.1. What happened to v3.0? Where did that disappear?

v3 is still happening; should be in handsets soon. It allows faster Bluetooth by piggy-backing on 802.11 (WiFi) PHY. v4 (low power) adds low power. Users of low-power probably aren't going to also want high-speed (battery eating) so v3 and v4 users are orthogonal to each other, which is why development looks like it is happening in parallel (which it is, really), i.e. both v3 and v4 are going ahead, but users probably want features of one or the other.

Malerocks, yeah, I was trying to be humorous... sorry, I think its clear any form of humor is not my strenght. 😊
