5G Core Testing
Emulate millions of subscribers, slices and fault events long before go-live.
Why 5G Core Validation Matters
A 5G Stand-Alone core is really a cluster of tiny apps (micro-services) that all have to answer thousands of requests every second. If too many phones try to register at once—or a new software release slips in a bug—the whole fabric can stall and customers lose service. Automated “lab storms” with Spirent Landslide let you hit the core with the worst-case load, trigger faults on purpose and watch every KPI in real time, so surprises never reach the live network.
