ULE - Ultra Low Energy is a wireless communication standard, which is used to create wireless sensor and actuator networks. The primary application areas of ULE based devices are home automation, home security, climate control. ULE originated from the DECT technology (thus it is often referred to as DECT ULE). In May 2013 ETSI released the specification of the ULE standard (Technical Specification TS 102 939-01). The basic ULE wireless network uses a “star network topology”; i.e. there is one main device, called “base”, which controls the network; the “base” is wirelessly connected to “nodes”, which usually are devices with dedicated functions, such as sensors, remote controls, actuators, smart meters, etc. Some examples of node devices – door locks, smoke detectors, motion detectors, remote controls, gas and electricity meters, baby monitors, elderly care, etc. ULE enables simultaneous data and voice communication; this means that sensors are not limited to indicating the event, but also enable voice interface. A good example is a pendant device for elderly care, which in case of emergency enables person carrying it not only indicate of an emergency situation, but also communicate with a remotely located caretaker, or service station as with regular cordless phone, but all with the simple press of a button. The ULE technology is promoted by the ULE Alliance, a non-profit organization, located in Bern, Switzerland. == ULE Evolution from DECT == Enhancements were made to the DECT transport layer level by ETSI Technical Group DECT to adapt it to the requirements of the ULE wireless sensor networks: * Low power operation, which enables ULE devices to operate on batteries for extended time period of years * Extended security – ULE is using strong 128 bit AES encryption scheme vs. 64 bit encryption of DECT Similarly to DECT, ULE uses a dedicated radio frequency, outmatching other technologies, such as Zigbee, Z-Wave, Bluetooth and others in terms of stability. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ULE - Ultra Low Energy」の詳細全文を読む スポンサード リンク
