Rohde & Schwarz and Huawei Technologies Co. Ltd. announced the successful demonstration of 1.6 Gbps LTE-A-Pro downlink throughput, using Huawei Balong 765, the industry’s first LTE modem to support category 19 at 1.6 Gbps technology.
In the Rohde & Schwarz and Huawei lab, the 1.6 Gbps download speeds were achieved by using a combination of up to four downlink FDD carriers on which carriers can be received separately on four transmission layers (4 x 4 MIMO) and 256 QAM data modulation. 3GPP 4 x 4 MIMO mandates four receive antennas on the device side, so four RF connections are needed. These are provided by the 4 x 4 MIMO functionality of the R&S CMW500 wideband radio communication tester.
“Both Huawei and Rohde & Schwarz are industry leaders in promoting the evolution of LTE-A-Pro technology. We are delighted to be working together to achieve this new milestone,” says Anton Messmer, VP mobile radio testers at Rohde & Schwarz. “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. The R&S CMW500 in its R&S CMWflexx configuration is the first test platform that offers an eCA solution for up to 8CC downlink, for protocol, RF and data performance verifications.”
“We are very pleased that Huawei has completed the test with Rohde & Schwarz and witnessed together the performance breakthrough in 4.5G industry,” said Ai Wei, fellow at Huawei. “The Balong 765 has become the first modem to support LTE Cat. 19 downlink and Cat. 13 uplink connectivity, enabling mobile broadband speeds of up to 1.6 Gbps. With advanced technologies of 8 x 8 MIMO, 5CC CA, 256QAM, the Balong 765 will help operators boost network capacity and will take consumers to higher-speed and highly immersive experience. Moreover, Balong 765 can help operators to provide reliable connectivity and roll out IoT solutions.”
At Mobile World Congress 2018 in Barcelona from February 26 to March 1, 2018, Rohde & Schwarz will showcase in Hall 6, Booth 6C40 a solution with eight aggregated downlink carriers. So the R&S CMW is the first test platform on the market that supports enhanced carrier aggregation (eCA), since it supports more than five aggregated downlink channels.
