Rohde & Schwarz presents world’s first WLAN signaling tester for IEEE 802.11ax

Believed to be the first tester to emulate all IEEE 802.11a/b/g/n/ac standards, including 802.11ax, the Rhode & Schwarz CMW270 wireless connectivity tester can be used in signaling mode to test the RF properties of WLAN stations under real-world conditions.

Before now, the RF properties of WLAN stations (STA) were mainly tested in an artificial remote control operation, the non-signaling mode. IEEE 802.11ax uses OFDMA technology to significantly increase the efficiency of WLAN networks. The available bandwidth is shared between multiple STAs that simultaneously transmit to the access point. This requires precisely co-ordinated timing among all STAs, and power levels need to be individually controlled, explains Rohde &Schwarz.

Based on the established R&S CMW270 wireless connectivity tester, which has a newly extended bandwidth of 160MHz, and using the new hardware option, the R&S CMW-B100H advanced measurement unit, engineers can emulate an 802.11ax access point to test the RF properties and performance of a STA under realistic conditions. The R&S CMW270 can also simultaneously and comprehensively test other devices, e.g. Bluetooth devices, advises Rohde & Schwarz.

Rohde & Schwarz will present the WLAN tester at Mobile World Congress 2018, Barcelona, Spain (Hall 6, booth 6C40), ahead of its availability in April 2018.
