VIAVI Solutions E500 Data Center Cabinet LTE Capacity Test The VIAVI Wireless E500 family provide powerful and easy to use network performance test systems based upon the TM500 – the industry standard test mobile for advanced network function and feature validation as well as performance assessment which are widely used by Network Operators, Network Equipment Manufacturers and Chipset Vendors. The system is fully scalable, connecting to tens of base station sectors, emulating tens of thousands of mobile devices and modeling real RF channel conditions. It is upgradable so that each mobile may be configured to support 2G, 3G, 4G technologies, and using advanced mobility models can create inter and intra technology handover scenarios. Real world user data applications can be generated for each mobile allowing true ‘end-to-end’ IP performance analysis. Comprehensive statistics and logging capabilities are also available for trouble-shooting. Benefits y Higher Density and Scalability - High performance system enabling higher number of carriers and UEs y Real-World Network Scenario Emulation – Realworld load emulation by mixing 3GPP features, channel conditions and data traffic for each UE y Leading Edge 3GPP Technologies – First to market and most advanced 3GPP Rel-10/11/12 technologies available today The E500-D Data Center cabinet is the latest generation of E500, which has been specifically designed for supporting highly scalable LTE-A and Multi-RAT network performance and capacity testing with higher density, scalability and flexibility. It is capable of supporting up to 24 Carriers per system with up to 36,000 UEs. With front to back airflow the E500-D cabinet is compatible with centralized data center labs layout, and meets the trend of global labs planning. A set of core test cases supported which the user can use to assess the performance of network features within a loaded network environment, or quality of experience of the subscribers who are with real-world behavior under complex test scenarios of HetNet, C-RAN, Small Cells deployment, FDD/TDD convergence, etc. A good example is that multiple trains arrive at and leave from the platform with subscribers migrating between application data and voice/messaging services.
