UeSIM is the complete solution for all LTE/LTE-Advanced/LTE-Advanced Pro testing needs. UeSIM allows full load of multiple LTE sectors with a single system. On each sector, thousands of simulated mobiles can concurrently generate load over the radio interface. Load & stress and functional testing over the radio interface encompass complete LTE protocol stacks and their applications. UeSIM can stress and monitor both the FDD/TDD radio interface and the Core Network. The available features support Carrier Aggregation (up to 8 carriers) over any FDD/TDD 3GPP band, Logical Cells configuration, eMBMS, VoLTE, 2×2/4×4 MIMO (with CA), IoT and more. Both RF and optical CPRI interfaces are supported. All configurations are fully scalable to test any eNodeB configuration, regardless of size.
