The measurement method introduced here is the Murata-original MIMO-OTA (Over the Air) evaluation specific to noise evaluation.
This evaluation method has the following merits.
A reverberation chamber is required to measure the Total Isotropic Sensitivity (TIS) that is total receiving sensitivity (formal evaluation). Reverberation chamber is one of evaluation systems recommended by the 3GPP system.
The measurement result in the following figure shows that the receiving sensitivity is more improved as the value decreases.
