5G/ Network Slicing / Latency

5G networks bring complexity, making end-to-end testing essential to ensure service functionality and performance. Therefore, comprehensive end-to-end testing is required in a multi-vendor 5G environment.

SEGRON provides complete end-to-end testing capabilities for 5G networks, covering all core nodes and interfaces. We enable the validation and assurance of key functions using real end customer devices, orchestrating automated testing through a single platform. In regions with non-uniform network coverage, our solution includes handover verification options to accurately assess user equipment (UE) behavior during interworking with 4G, 3G, and other networks in areas with no 5G coverage. Our capabilities also extend to testing and verifying network slices, fast download speeds, and low-latency scenarios (eMBB, URLLC & mMTC).
