Software enables R&S CMW500 to perform LTE-A 3x carrier aggregation
In the test, R&S also utilised a current LTE-A modem from Qualcomm, Inc. According to R&S, the test has shown that this 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 Qualcomm’s LTE-A modem will enable mobile operators to offer higher peak data rates to their subscribers in future applications, provided they have acquired the frequency spectrum. The test also showcased benefits across the supply chain and speeds up the commercial launch of LTE-Advanced 3x Carrier Aggregation functionality.
The CMW500 is the suits the demand of test labs seeking high 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.
