Bluetooth 4.0 Spec Adopted

Posted by timothy on from the so-my-money's-wasted-on-nuclear-batteries dept.

adeelarshad82 writes "The Bluetooth SIG announced the formal adoption of Bluetooth Core Specification Version 4.0, which begins the qualification process for new, low-power devices. Bluetooth 4.0 [zipped PDF of the spec] was formally announced in April, and added a new, ultra-low-power aspect to the short-range personal-area-network technology. According to the SIG, the new 4.0 core specification should allow devices to run on coin-cell batteries for years with a new ultra-low-power duty mode."

    Why do people insist on looking down at those who talk to their friends that just don't happen to be proximate?

    I mean, jeez! There you go, yacking away with your homies and I can't do the same 'cause mine are not beside me?

    What kind of technophobe are you?

    This bit from TFA links has me a bit worried. With the mobility of these devices compared to WiFi, which is relatively non-mobile, what sort of walking interference (Bluetooth vs. WiFi) can we expect from 4.0 devices?

    Moreover, an increased modulation index has actually increased the effective range from 30 feet or so, to beyond 200 feet.
