RANReplay

RANReplay is a web + desktop app for network engineering teams to capture, sanitize, and replay real 5G/NSA/SA problem scenarios in a lab or simulator. It ingests device logs, modem traces, and network-side counters, then builds a time-aligned “session timeline” showing handovers, RRC state changes, QoS flows, and latency spikes. With one click, teams can export a reproducible test recipe (traffic model + mobility pattern + RF assumptions) to validate fixes before rolling them into the live network. An AI assistant helps summarize root-cause hypotheses and highlights the smallest set of signals needed to reproduce the issue, but the core value is deterministic replay and shareable artifacts. This is not consumer-facing; it’s a pragmatic tool for operators, private 5G integrators, and vendors who waste days trying to recreate intermittent field failures.
