The E600 is a multicavity mode-stirred source-stirred reverberation chamber represents that state-of-the-art in reverberation chamber technology. E600 provides unique up to 8x8 MIMO measurement capabilities of antennas and passive RF front-ends [Efficiency, Correlation, Mutual Coupling, MIMO Capacity, Diversity Gain (ADG, EDG, IDG), loss effects (DGL, CL.MIMO), active MIMO Over-The-Air (OTA) 3GPP/CTIA Figures of Merit for 2G, 3G, 4G and 5G cellular including CA up to 8x8 MIMO x 8DL CC and any wireless LAN system (including 802.11ax) (Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS), MIMO Throughput (TPUT), CQI, MIMO Throughput Sensitivity (MTS), MIMO to Transmit Diversity Threshold (M2TxdT)], time-domain measurements [RMS Delay Spread (RMS DS), Power Delay Profile (PDP), Coherence Bandwidth (CBW), Path Loss (PL), Standard Deviation (STD), TCP/UDP Throughput versus time, path loss or averaged received power in both downlink and uplink (DL/UL) paths], VDT-OTA, Mute% sound acoustic and channel parameters (PDF, CDF, Scatterplot, k-factor, eigenvalues) for AuTs/DUTs of up to 50cm and 50kg, and a wide variety of Rayleigh, Rician, NIST Indoor-Urban, isotropic SCME Urban-Macro#, isotropic SCME Urban-Micro# and other fading environments, all united in one single and intuitive interface for an enhanced frequency range that now covers LTE Band 71. There is no RC in the market more advanced than the E600.

The figure shows LTE-A 4x4 x 2DL CC and LTE-A 2x2 x 4DLCC MIMO OTA TPUT tests using a smartphone and E600 RC, exhibiting 100% total Throughput, in excess of 700 Mbps absolute value for 4x4 x 2DL CC.

Also the figure shows a 5G NR NSA 2X2 MIMO 100 MHz channel BW exceeding 800 Mbps in MAC layer.

Typical testing times are under 1 minute for TRP and 6 minutes for TIS, with typical accuracies under 0.5 dB STD using novel source-stirring (1dB for Band 71).
