Maximized WiMAX™ data throughput and s ­ imultaneous in-depth analysis of MAC and PHY layers­ By using the R&S®CMW270, engineers can optimize the performance of their mobile station designs. The achievable data rate is basically determined by the capacity of the interfaces involved. To discover possible throughput limitations, communications data handling between the base station and the mobile station must be carefully evaluated. Only application-based testing allows the full functionality of a mobile station to be verified. The test equipment must measure the real data throughput of the device...

Multipath propagation for MIMO applications with minimal hardware expenditure in the lab MIMO in particular requires the testing of mobile stations under real-world multipath propagation conditions to exploit its full benefits. The achievable data throughput is an important criterion for network operators selecting enduser equipment. Moreover, communications data handling between the base station and the mobile station must be carefully evaluated to discover possible throughput limitations. Effects resulting from channel fading have significant impact on the overall performance of the system....

Automated performance and sensitivity m ­ easurements for R & D and benchmarking The evaluation of IP performance as well as sensitivity measurements taking into account all transmission-­ relevant channel and signaling parameters requires a significant test effort in terms of time and technology.
