Radio comms tester adds IEEE 802.11ac signalling

Article By : Rohde & Schwarz

The R&S CMW500 wideband radio communication tester can be used to measure LTE-WLAN traffic offloading or analyse coexistence interference in the DUT.

Rohde and Schwarz' CMW500 wideband radio communication tester now emulates WLAN networks in line with the IEEE 802.11ac standard.

Many manufacturers of WLAN components limit their device and component testing to conventional WLAN access points. But this doesn't allow, for example, coexistence tests on devices that simultaneously communicate over WLAN and other wireless technologies. If users have unlimited access to the protocol stack, as provided by the new R&S CMW-KS656 software option, they can easily eliminate incompatibilities. The ability to upgrade the stack to meet future requirements makes it a safe investment.

In signalling mode, users can now use the R&S CMW radio communication tester to analyse more than the RF characteristics of transmitters and receivers. They can test applications and the speed of a WLAN connection under realistic conditions in accordance with the IEEE 802.11ac standard.

Coexistence interference occurs when multiple wireless technologies are operated in parallel, such as when WLAN and a mobile network are both enabled on a smartphone or tablet, according to the company. The R&S CMW500 wideband radio communication tester can be used to analyse even very complex sequences, for instance to measure LTE-WLAN traffic offloading or analyse coexistence interference in the DUT.
