Based on test plans for IoT integrators, Rohda & Schwarz's IoT carrier acceptance test system offers RF, protocol and performance test cases in a single box.

Since too many IoT devices can overload networks and impair their performance, these devices must be tested to ensure that networks function properly. To this end, U.S.'s largest wireless network operator has published a Host Device Certification Test Plan for manufacturers of IoT-enabled devices. The certification test plan goes beyond the basic requirements set down by 3GPP (the standardisation body for wireless communications) and defines additional requirements for subscriber devices in the network.

R&S TS 290, which offers a flexible test system for Cat 1, is capable of supporting future IoT tests from other network operators, dependent on the required test scope.

The R&S TS 290 test system is made up of an R&S CMW290 functional radio communication tester and the R&S CONTEST sequencer software. The software runs provider-specific RF, protocol and performance test cases—fully automatically and with reproducible results. Users, even those without programming knowledge, can create their own test plans conveniently with the drag-and-drop function.

The R&S CMW290 functional radio communication tester meets the specific requirements of IoT integrators and their typically cost-sensitive applications, according to the company. The tester handles cellular technologies such as LTE as well as WLAN and Bluetooth. For end-to-end application testing, the R&S CMW290 can simulate a cellular network and set up a connection between the application on the device or system and the server. This enables users to verify the correct functioning of platforms with integrated wireless modules in a defined network.

The R&S TS 290 IoT carrier acceptance test system is now available from Rohde & Schwarz.
