Extremely Simple Sensor Radio Protocol for Processorless Implementationx

Low end extension (LEE) for Bluetooth is a technology that enables devices very limited in power consumption, processing capabilities and memory to connect themselves to mobile terminals and other devices that currently feature a Bluetooth radio. Obviously, there are a number of small-sized devices that could add value by having wireless radio connection to mobile terminal but cannot bear the power consumption and cost associated to Bluetooth. LEE introduces minor additions to the Bluetooth chip in mobile terminals in order to allow major savings in power consumption and cost in the radios embedded into small devices such as wireless sensors and terminal enhancements. This paper presents the principles of LEE radio protocol, addresses the system capacity and elaborates the protocol implementation
