Bluetooth 4.0 to have low energy requirements

Bluetooth 4.0 takes things down a notch by certifying single-mode low energy devices in addition to dual-mode devices that incorporate both the low energy side of the spec plus either 2.1+EDR or 3.0. In a nutshell, the technology should bring a number of new categories and form factors of wireless devices into the fold since 1Mbps Bluetooth low energy can operate on coin cells -- the kinds you find in wristwatches, calculators, and remote controls -- and the SIG's pulling no punches by saying that "with today's announcement the race is on for product designers to be the first to market."
