5G Testing
Ensuring every slice, signal & service performs—before your subscribers ever notice.
Key Challenges at a Glance
5G Core
Signalling storms from mass UE registrations or slice activations can saturate the control plane in seconds. Once the SBA micro-services buckle, calls drop and PDU sessions fail.

Open RAN
Eleven new open interfaces must interoperate at sub-millisecond latency. Any RU, DU or CU software update can break links—and lab RF realism is notoriously hard to reproduce.

Cloud & Virtualization
Containerised network functions must crash-recover and resynchronise state in seconds. Across hybrid clouds, autoscaling limits and noisy neighbours put SLAs at risk.

Three Targeted Solutions
5G Core Validation
Spirent Landslide hammers the 5GC with millions of simulated UEs, slice loads and fault events, all triggered by APNT’s CI/CD hooks, proving every micro-service before launch.
Detect overload thresholds before subscribers do
5G Open RAN Testing
A single rig blends Vertex fading with RU/DU/CU models to drive every O-RAN split, replay field logs and run RIC apps under real-world RF, exposing interop gaps fast.
Find interop defects days—not weeks—after a vendor drop
Validate xApp/rApp behaviour under realistic RF impairments
Reduce field-trial time & cost with repeatable lab playback
5G Cloud Assurance
