WLAN 2x2 MIMO signalling tester to get MWC outing

Multiple input multiple output (MIMO) is a multi-antenna method that uses multipath propagation to boost data rates in wireless communications. The transmit and receive antennas must be spatially separated from each other. The compact design of mobile devices such as smartphones is a limiting factor.

These devices can hold at most two transmit and two receive antennas, which limits transmission to 2x2 MIMO.

This solution also allows users to determine the data throughput in the transmit and receive directions.

In signalling mode, the CMW270 emulates a WLAN 11ax access point (AP) to which the DUT, a WLAN station, is connected in normal mode.

Unlike commonly used non-signalling mode, tests and measurements in signalling mode have the advantage that the user performs them under realistic conditions and does not need wired remote control with device-specific control software for the DUT.

The CMW270 is ideal for more than just signalling tests in line with the IEEE 802.11a/b/g/n/ac/ax WLAN standards.

It can also comprehensively and simultaneously test Bluetooth devices, for example. The R&S CMW270 also supports RF tests for ZigBee and Thread components in line with IEEE 802.15.4.
