Ultra Low Energy (ULE) is an extension of the Digital Enhanced Cordless Telecommunications (DECT) physical layer specification that supports low power devices. ULE is being promoted by the ULE Alliance as a way to provide sensors, actuators and other smart devices in the Internet of Things (IoT) with two-way transmission capability over a dedicated frequency band of 1900MHz.
ULE supports an advanced family of low-power system-on-chip (SoC) and modular chipset products that provide:
Outstanding range - ULE has over 600 meters of range outdoors, compared to less than 500 meters for Z-Wave and WiFi. Provides superior indoor coverage moving through walls, ceilings
Robust and secure RF channels - all communication in ULE is encrypted with the Advanced Encryption Standard using AES-CCM. There is no un-encrypted mode and no option to switch off encryption as in legacy DECT or other technologies.
Two-way voice and video support - ULE's high bitrate can support data, two-way voice and video.
While the use of internet-connected devices and voice controls is growing, they face reliability and security issues. Mass-adoption of IoT solutions requires a technology with a comprehensive communication range and an interference-free spectrum band that enables high reliability and good user experience. There is already a large install base of 50 million gateways deployed with DECT connectivity for telephony, so it makes sense for these gateways to become IoT hubs -- especially since it only requires a wireless software update. ULE's support of two-way voice corresponds with the market dynamics of voice user interface (VUI)
