Bluetooth low energy or Bluetooth LE or(BLE) branded as Bluetooth SMART since 2011 is a wireless computer network technology which is aimed at novel applications in the healthcare, fitness, security, and home entertainment industries. Compared to "Classic" Bluetooth, BLE is intended to provide considerably reduced power consumption and lower cost, whilst maintaining a similar communication range (see table below).
Bluetooth LE was originally introduced under the name Wibree by Nokia in 2006, but it was merged into the main Bluetooth standard in 2010, when the Bluetooth Core Specification Version 4.0 was adopted.

Famous quotes containing the word energy:
“Reckoned physiologically, everything ugly weakens and afflicts man. It recalls decay, danger, impotence; he actually suffers a loss of energy in its presence. The effect of the ugly can be measured with a dynamometer. Whenever man feels in any way depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with the ugly, they increase with the beautiful.”
—Friedrich Nietzsche (1844–1900)
