The LTE standards typically used for IoT are standardized by 3GPP as Cat.1, Cat.1+eDRX, and Cat.M1, and globally chip venders are developing and releasing communication chip.
To measure the low power consumption performance of IoT devices, tests are performed by connecting an Anritsu base station simulator to the IoT device implementing a communications chip via Cat.1, Cat.1+eDRX, and Cat.M1 on the air interface.
Anritsu started development targeting the Cat.1+eDRX communication standard for IoT, as well as the latest Cat.M1 standard at an early stage. Following the base station simulators used in the tests with KDDI this time, Anritsu plans support for radio communications analyzer, and the conformance test system. Anritsu will continue to provide total measurement solutions for R&D and I&M of IoT devices for various applications such as smart home, smart factory, and smart city applications.
