5G Open RAN Testing

Validate every RU, DU & CU under real-world RF, mobility and xApp control before a single tower goes live.

Why Open RAN Testing Matters

Open RAN lets you mix-and-match radio vendors, but that freedom adds eleven new “open” interfaces that all have to talk in real time. A tiny mismatch in timing, an RF impairment the lab didn’t catch, or an xApp that over-tunes power can drop user throughput in seconds. Spirent’s wrap-around testbeds recreate every interface, every radio condition and every RIC decision in the lab, so multi-vendor surprises never make it to the field.

How the Test Workflow Looks

1
UE & Channel Emulator
Generates thousands of virtual UEs and realistic fading / mobility.
2
RU / DU / CU Under Test
Drives each open interface (Fronthaul, Midhaul, Backhaul) at scale.
3
RIC & Closed-Loop Apps
Runs xApps / rApps that steer traffic, power & hand-overs in real time.
4
KPI Dashboard
Live pass/fail for throughput, EVM, latency & interop—exported to Grafana.
Outcomes You Can Count On

Key Benefits

Open_RAN-1
Interop Without Guess-Work

Confirm every RU, DU & CU combination meets O-RAN specs and vendor SLAs before integration costs mount.
Open_RAN-1
Accelerated Releases
Pre-built test libraries plug into any CI/CD pipeline, shrinking vendor drop validation from weeks to days.
Open_RAN-1
True RF Realism
Vertex fading recreates Doppler, multipath and high-speed mobility—no expensive drive tests required.
Open_RAN-1
RIC Confidence
Wrap-around RIC tests show xApps and rApps optimise QoE without breaking latency budgets.
Open_RAN-1
Lower Field-Trial OPEX
Replay lab-captured logs to reproduce—and fix—issues fast, cutting truck rolls and pilot-site costs.
