Note that power consumption is not part of the Bluetooth specification. Compatibility The Bluetooth low energy protocol is not backward compatible with classic Bluetooth protocol. However, Bluetooth low energy technology and Bluetooth technology operate on the same spectrum so the underlying hardware is likely to be similar. A given device may be able to operate as a Bluetooth low energy technology and Bluetooth device using the very same chip and radio hardware, though not simultaneously; this is a Bluetooth 4.0 device. More dual-mode smartphones, laptops and tablets that support Bluetooth 4.0 (which includes both Classic Bluetooth technology and Bluetooth low energy technology) are expected to be released in late 2011 and early 2012. Application profiles The commonly available specification of Bluetooth low energy application profiles has to be expected prior to commonly available appliances. Currently there are hints that application
