Bluetooth 4.0 finalized: low power mode & boosted range
Bluetooth 3.0 may still be a rarity on devices, but the Bluetooth Special Interest Group (SIG) arenÃ¢â‚¬â„¢t letting that stop them from whipping ahead with the next spec in line. Bluetooth 4.0 has been finalized, and it delivers both a new low-energy mode suited to indecently frugal devices like watches, sensors and remotes, together with a boost in potential range. While the SIG expect most devices to stick with the regular 30 foot/10m range, Bluetooth 4.0 theoretically supports up to 200 feet and beyond.
That, they say, will help wireless sensor manufacturers build their mesh-style networks, and the fact that the specification allows for ultra-low-power hardware thereÃ¢â‚¬â„¢ll be less battery changing or charging too. Of course, weÃ¢â‚¬â„¢ll have to wait a while to actually see devices using the new standard: Bluetooth v4.0 hardware isnÃ¢â‚¬â„¢t expected to reach the market until late 2010 or early 2011.
