The TM500 is a scalable test system for validating network performance as experienced by end users, across multiple cells and different radio access technologies. Although 4G coverage is rapidly expanding, legacy technologies, such as 2G and 3G, will continue to play a significant role for many years to come. Until now it has been a real challenge to prove that network capacity is adequate in a multi-standard heterogeneous network (HetNet) environment, and that mobile terminals can hand over effectively between different technologies, to ensure a seamless user experience. This is vital to maintain customer satisfaction and reduce churn.
The TM500 from Cobham Wireless is able to measure the complete performance of the network, from RF through to the packet core &ndash this includes interaction with other users, the simulated RF environment and mobility, accurately replicating real-world user behaviour profiles such as web browsing, emails, downloading files, video streaming and Voice over LTE (VoLTE), together with mobility across the radio access network.
A set of core test case scenarios allows the user to assess the performance of network features within a loaded network environment. The TM500 supports multiple real stateful data applications enabling true end-to-end data generation and analysis per emulated mobile device. Test cases can easily be configured for thousands of application data flows, and allocated to different mobile device groups with different traffic profiles.
