Comprion First to Offer Validated PSM and eDRX Tests for Mobile IoT Devices

December 04, 2018 / Ken Briodagh

The mobile network standardization body 3GPP recently introduced two new features, PSM (Power Saving Mode) and eDRX (extended Discontinuous Reception), to minimize power consumption of IoT devices and extend battery power up to ten years. In IoT applications such as container tracking, intelligent meters, or agriculture sensors, the devices do not need to send or receive data continuously. “Being an important member of the mobile ecosystem, we felt the need to test the UICC interface for devices that support PSM and eDRX in order to prevent unpleasant surprises when the devices go live in mobile networks,” said Oliver Wruck, Director MNTS, Comprion. PSM and eDRX Features In PSM, the device can switch to a sort of power-off mode for an agreed amount of time. If the device must transmit data, it can wake up without the need of reattaching to the network and the necessary signaling. eDRX makes it possible to considerably extend the time interval during which the device is not ...
