Bluetooth SIG Announces Low-Energy Adoption
Today the Bluetooth Special Interest Group announced that it has formally adopted Bluetooth Low Energy technology, which is part of the Bluetooth 4.0 core specification. By dropping energy requirements of Bluetooth devices, it will allow improvements such as: ultra-low peak, average and idle mode power consumption; the ability to run for years on standard coin-cell batteries; low cost; multi-vendor interoperability; and improved range. Manufacturers can use current Bluetooth (Bluetooth 2.1+EDR or Bluetooth 3.0+HS) chips with the new low energy stack. The Bluetooth SIG also points out that Bluetooth low energy can send very small packets at 1Mbps, can hop across frequencies, has latency of just 3ms, and is secure. The Bluetooth SIG expects devices using Bluetooth low energy to be available by the summer of 2010.
