Rohde & Schwarz demonstrated the first signaling test solution for WLAN 2x2 MIMO stations in line with the IEEE 802.11ax standard at Mobile World Congress 2019 in Barcelona. In signaling mode, the R&S®CMW270 wireless connectivity tester emulates a WLAN 11ax access point (AP) to which the DUT, a WLAN station, is connected in normal mode. This enables the user to perform measurements under realistic conditions. Using the well-established R&S CMW270, developers can test the RF characteristics of both transmitters and receivers and also determine the data throughput in both directions.
