Low end extension for Bluetooth

Low end extension (LEE) for Bluetooth is a technology to solve a simple mismatch. There are several small devices that could add value by having wireless radio connection to a mobile terminal but cannot bear the power consumption and cost associated with Bluetooth. However, mobile terminals are scheduled to have Bluetooth as the short-range wireless solution. LEE tackles the mismatch by introducing minor additions to the Bluetooth chip in mobile terminals that allows major savings in power consumption and cost in the radios embedded into small devices. Examples of the small devices include wireless sensors, toys, wireless pens etc. This work presents the principles of LEE radio technology and highlights some implementation issues.
