Bluetooth 4 ready, devices expected later this year

Bluetooth Special Interest Group (SIG) unveiled additional information on Tuesday about the forthcoming Bluetooth 4.0 specification due out end of Q2 2010 (summer time).

Bluetooth 4 is nearly ready and with it the focus is on battery life, energy efficiency and more devices. Bluetooth 4 combines three specifications in one: classic Bluetooth wireless; high speed Bluetooth; and the new Bluetooth low energy. SIG believes that sensors like pedometers and glucose meters will run on the low energy spec and could potentially run for weeks without needing to be recharged.

Bluetooth 4 also improves the range of reach for the technology. Classic Bluetooth only offers 10M (30ft) of range but with 4.0 devices will be capable of 60M (200ft). The full Bluetooth 4 spec is expected to be completed before June 30, 2010. Bluetooth 4 devices are expected to hit the market in late 2010/early 2011.

Love the idea about those pedometers, would probably make catholic churches a lot safer for young boys.
(lol it's late and I laughed so hard when I read the word "pedometer" so I thought I'd share my thoughts ;P).

Whatever happened to Bluetooth 3?

I was wondering the exact same thing. Last I checked 2.1 was the latest version. never heard of bluetooth 3 ever and now we have 4. Chrome fever?

Windows Phone 7 won't support Bluetooth 3, and here we go....Bluetooth 4 is coming...!!

Did they say they weren't going to support 4? I'm not saying that's what's going to happen but it would make sense that if 4 is going to be ready, they put that in it.

60M range sounds good
but what exactly is 'high speed bluetooth'?
can't seem to find a exact data transfer speed on their website

"It supports theoretical data transfer speeds of up to 24 Mbit/s"

This will be useful, especially the extended range with high speeds. Having used Bluetooth on and off, these are two factors that continue to annoy me.
