Rohde & Schwarz achieves LTE-A 3x Carrier Aggregation Category 9 IP throughput using the R&S CMW500
Utilizing a new Qualcomm Technologies LTE-Advanced modem, Rohde & Schwarz has successfully demonstrated the ability to sustain full protocol stack data rates for LTE Category 9. This milestone gives mobile operators a clear path to the commercial launch of LTE-A 3x Carrier Aggregation.
Munich, December 12, 2014 – Rohde & Schwarz announced today that the company has extensively tested the user plane throughput of Category 9 in compliance with 3GPP Release 10 for LTE-Advanced. Utilizing a device based on the latest LTE-Advanced modem from Qualcomm Technologies, Inc. (QTI), a wholly owned subsidiary of Qualcomm Incorporated, the R&S CMW500 wideband radio communication tester simulated an LTE-Advanced network, which carried data on three downlink carriers to the device under test. As the only available test platform that combines RF and protocol tests for Category 9 devices, the R&S CMW500 supports full stack verification from RF up to the application layer.
The test has shown that QTI?s LTE-Advanced modem provides stability and support for the aggregation of three downlink component carriers, each with a bandwidth of 20 MHz and a 450 Mbps user plane data rate in the downlink. User equipment based on QTI?s LTE-Advanced modem will enable mobile operators worldwide who have acquired additional segmented spectrum to offer higher peak data rates to their subscribers in future applications. The test also showcased benefits across the entire supply chain and speeds up the commercial launch of LTE-Advanced 3x Carrier Aggregation functionality.
The R&S CMW500 is the perfect choice for test labs seeking maximum flexibility in T&M equipment. The wideband radio communication tester offers the performance necessary for advanced testing of the required 450 Mbps data rate up to the IP level for Category 9, as well as Category 10 in the future. It also supports three 20 MHz component carriers in the downlink ? including 2×2 or 4×2 MIMO ? without any restriction when it comes to placing bands in the spectrum and the bandwidths used. Until now, scenarios for LTE-Advanced Carrier Aggregation were usually implemented with two component carriers, each with a bandwidth of up to 20 MHz and a total data rate of 300 Mbps in the downlink (Category 6). Devices operating to Category 9 performance standards make it possible to increase the downlink throughput by up to 150 Mbps.
The R&S CMW500 wideband radio communication tester software options for LTE-A 3x Downlink Carrier Aggregation for LTE FDD and LTE TDD are now available from Rohde & Schwarz.
