At MWC2018, ZTE reached a milestone by successfully completing the implementation of a DL Cat-18 device. Verified by Rohde & Schwarz, ZTE demonstrated its new 1.2 Gbps Smartphone with a test setup based on R&S CMW500 mobile communication tester. The smartphone supported download speed up to 1.2 Gbps by using 3CC downlink carrier aggregation with 4x4 MIMO and 256QAM modulation.
The ZTE 1.2 Gbps Smartphone supports the combination of up to 3CC downlink carriers on which carriers can be received separately on four transmission layers (4x4 MIMO) using a modulation of 256QAM. The R&S CMW500 mobile communication tester from Rohde & Schwarz was used to verify the proper functionality of the mobile device.
The R&S CMW500 is the ultimate test platform for simulating and verifying the combination of signaling and end-to-end data transmission on the involved carriers, regardless of the 3GPP-defined band configuration to be tested. For testing LTE in unlicensed spectrum configurations, the downlink carriers could even be set up in the 5 GHz unlicensed spectrum. This is important for 3GPP features such as License Assisted Access (LAA). The R&S CMW500 in its R&S CMWflexx configuration is the first test platform that offers enhanced carrier aggregation (eCA) capabilities for up to 8CC including 4x4 MIMO, for protocol, RF and data performance verifications.
The test setup including ZTE 1.2 Gbps Smartphone and the R&S CMW500 wideband radio communication was demonstrated at the recently concluded MWC2018 in Barcelona from February 26 to March 1, 2018.
