Commsolid and Rohde & Schwarz demonstrate wake up signal test for improved power efficiency in NB-IoT devices

Rohde & Schwarz and Goodix (CommSolid) are first to demonstrate exhaustive test functions for the newly introduced NB-IoT wake up signal (NWUS), the latest 3GPP Release 15 feature for NB-IoT devices to further reduce power consumption. For NB-IoT long-term monitoring applications, this wake up signal can be leveraged to enable either far longer battery life without upgrading the battery, or as a way to reduce battery size while retaining the device’s service life.

The test and measurement equipment expert Rohde & Schwarz and the cellular IoT company CommSolid by Goodix have partnered up to demonstrate the effectiveness of the NB-IoT Release 15 feature wake up signal in reducing the power consumption of NB-IoT devices. Test functions newly implemented on an R&S CMW290 Functional Radio Communication Tester are employed to outline the difference in power consumption for NB-IoT devices with and without the wake up signal technology.
