Full protocol stack data rates for LTE Category 9 demonstrated
The demonstration was carried out on the CMW500 wideband radio communication tester, which simulated an LTE-Advanced network that 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 CMW500 supports full stack verification from RF up to the application layer.
The test has shown that the LTE-Advanced modem from QTI 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 this 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 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 CMW500 wideband radio communication tester software options for LTE-A 3x Downlink Carrier Aggregation for LTE FDD and LTE TDD are now available.
