The Qualcomm® Snapdragon™ X16 LTE modem, a product of Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, supports the combination of up to three downlink carriers on which two carriers can be received separately on four transmission layers (4×4 MIMO) and an additional carrier on two layers (2×2 MIMO). 3GPP 4×4 MIMO mandates four receive antennas on the device side and thus needs four RF connections, which are provided by the R&S CMW5004x4 MIMO functionality.
The R&S CMW500 is the ultimate test platform to simulate and verify the combination of signaling and end to end data transmission on the involved carriers, no matter the 3GPP defined band to be tested. Two of the downlink carriers could even be set up in the 5 GHz unlicensed spectrum, for testing LTE in unlicensed spectrum configurations.The R&S CMW500, in its R&S CMWflexx configuration, is the first test platform that offers a downlink carrier aggregation solution for up to three 4×4 MIMO carriers, for protocol, RF and data performance verifications up to 1 Gbp/s.
