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.
