Bluetooth 4.0 To Reach Devices In Fourth Quarter

Posted by samzenpus on from the roll-it-out dept.

angry tapir writes "The Bluetooth 4.0 wireless specification could start to appear in devices such as headsets, smartphones and PCs by the fourth quarter, said the Bluetooth Special Interest Group. The new specification will be able to be used in lower-power devices than previous versions of the technology, including watches, pedometers, smart meters and other gadgets that run on coin-cell batteries."

    Of course, the act of including Bluetooth transforms them from "run years on a single battery" to "run from outlet to outlet".

    Even with BT 4.0, I'd love to see a power usage comparison, I'm sure IR would easily win.

    seriously, I can watch the battery on my cellphone die when the bluetooth is on.

    That's easy to solve:
    Use IR to turn on the TV, have the TV and remote couple after they both turn on. This way you'd only have to point the remote at the TV to turn it on.

    You can't compete with IR if you need a constant radio link. The beauty of IR is that when no button is being pressed there is no need to transmit or receive anything so it can power down to using a few micro-amps.

    Bluetooth has to maintain a connection between the devices so you are never going to get years out of a single set of batteries like you can with IR.
