On December 14-16, 2015, Guangzhou -China Mobile Communications Corporation held the 2015 Global Partner Conference at the Poly World Trade Center Expo in Guangzhou. As a close partner of China Mobile, Rohde & Schwarz actively participated in the development of certification and test cases related to the mobile research and terminal company warehousing tests. This time, China Mobile demonstrated the latest terminal test system at the terminal Shining 4G+ booth, namely the LTE international roaming system and the downlink carrier aggregation terminal verification system based on the R&S CMW platform, which received wide attention and unanimous approval from the leaders and industry insiders.
The LTE international roaming test system builds the airport scenes of important global visiting countries by collecting real network parameters, and in the laboratory through the network simulator R&S CMW500 real analog terminal in the international roaming environment function and performance, especially the terminal's first arrival in the roaming ground Network delay, call, SMS, Internet and other basic business performance, is the world's first LTE international roaming test system.
The downlink carrier aggregation terminal verification system simulates the dual-carrier aggregation scenario of the existing network through two network simulators R&S CMW500, verifies the throughput of different fading scenarios of the terminal and the long-term stress test, and then smoothly upgrades to support the TDD-LTE carrier aggregation downlink 3CC and Upstream 2CC test. The system hardware can be compatible with the international roaming or protocol conformance test system. Under the existing hardware platform, the NS-IOT carrier aggregation test can be supported only by a small amount of investment in the upgrade software.
