DECT ULE
The latest DECT variant is DECT ULE, or DECT Ultra low energy. The standard was first discussed in January 2011 and the first commercial products were launched later that year by Dialog Semiconductor. Like DECT, DECT ULE standard uses the 1.9 GHz band so suffers less interference than Zigbee, Bluetooth or Wi-Fi, which all run on 2.4 GHz.
The standard has been created to enable home automation, security, healthcare and energy monitoring applications that are battery powered and can easily connect to the web using the large number of existing DECT enabled modems and be managed using a smartphone app.
