Bluetooth 4.0 will expand Bluetooth functionality to watches and other gadgets that run on coin-cell batteries.
Good Gear Guide reports that Bluetooth 4.0 may show up in devices such as headsets, smartphones and PCs by Q4 2010. Bluetooth SIG's Executive Director, Michael Foley, says that in addition to the high-speed capabilities introduced in Bluetooth 3.0, Bluetooth 4.0 will include a low-energy specification for transmitting small bursts of data over short ranges.
According to Michael Foley, Bluetooth 4.0 radios will consume roughly the same amount of power as Bluetooth 3.0 radios when used to sync smartphones with laptops or listen to music with wireless headphones. However, the new low-energy specification will expand Bluetooth functionality to watches, pedometers, smart meters and other gadgets that run on coin-cell batteries.
