RADISYS SOLUTION BRIEF | Radisys 5G Software Suite – Empowering Test & Measurement Solutions
Scalability
Scalability of the solution is paramount, specifically for UE test solutions. Radisys software solution enables
test solutions to measure performance and scalability of gNB/ eNB by emulating hundreds of users.
Visibility
Test solutions provide visibility on the System-under-Text (SUT). Visibility parameters such as KPIs,
counters, and logs are must for the users to understand how the SUT is performing under different
environment. Radisys solutions offer standard and custom counters and KPIs. Additionally, extensive
logging throughout the solution offers good visibility into the state of the whole system.
