Prove the experience — not just the network.
Continuous, 24/7 measurement of radio quality and true end-to-end performance from a single probe — across every operator, slice and private network. Not a one-off drive test: always-on, user-level SLA proof at the lowest cost per monitored point, for neutral-host venues, industrial private 5G and mission-critical RF.
CE & FCC certified · GDPR compliant · Deployed across operators, neutral-host venues, ports, mining and critical infrastructure.
Monitoring the infrastructure doesn't prove the experience.
SLA compliance is decided where people actually stand — at the platform edge, the loading dock, the apron, the pit face. A core dashboard that reports the network is “up” can't tell you what a handset, a user or a connected machine actually gets. The Watchdog measures it directly, continuously, from the point of use.
A dedicated probe for continuous, user-level assurance.
Passive RF metrics
RSRP and RSRQ for every cell and operator the module detects — no SIM required, fully neighbour-aware. SINR, PCI and CQI come from the serving cell once a SIM is attached.
Continuous active E2E performance
Latency, jitter and smart DL/UL throughput against your own targets — scheduled or on-demand.
Automated service-level tests
VoLTE/VoNR call-setup, drop rate and eMOS, plus real-device application QoE such as Microsoft Teams MOS.
Proactive detection
Catch degradation before users complain. UP / DEGRADED / DOWN states auto-raise incidents to your NOC.

Switches the active SIM/eSIM profile automatically between runs, across physical SIM slots or eSIM profiles — no human touch.
Test every operator from a single probe.
| Physical SIMs (multiplexer) | Multi-IMSI SIM | ★ Native eSIM (eUICC) — Recommended | |
|---|---|---|---|
| Profile capacity | Up to 4 slots | 1 SIM, several IMSIs | Up to 10 profiles (SGP.32) |
| Switching | GPIO-serial mux | IMSI re-attach | AT command via on-device LPA |
| MNO attachment | Direct per SIM | Indirect via anchor | Direct per profile |
| Roaming cost | None | Roaming + interconnect | None |
| Remote provisioning | On-site swap | Fixed at manufacture | Over-the-air |
Attach in-country, in every market.
National-SIM compliance where local regulation demands a domestic profile — so tests attach where other probes are rejected.
Standalone probes — or full-stack assurance.
Every Neutroon Watchdog is powered by the Neutroon Platform — templates, KPIs, SLA thresholds, incidents, dashboards and APIs. Deploy standalone for point-of-use assurance, ideal for operators with no infrastructure access required. Or combine with Neutroon's network-infrastructure monitoring for Private 5G/LTE and DAS to correlate user experience with infrastructure health.
Standalone Watchdogs
User-level multi-operator assurance from the probe alone. No core or RAN access required — the typical deployment for mobile operators monitoring third-party coverage.
Watchdogs + infrastructure monitoring
Pair Watchdogs with Neutroon Platform monitoring for Private 5G/LTE and DAS to deliver full-stack assurance and faster root-cause analysis.
Built for the networks people depend on.

Frequently asked questions.
Common questions from operators, neutral-host venues and industrial buyers evaluating the Neutroon Watchdog. Don't see yours? Get in touch.
What is the Neutroon Watchdog?
The Neutroon Watchdog is a multi-operator RF and service-assurance probe that continuously measures radio quality and true end-to-end performance from a fixed location, across every mobile operator, network slice and private network.
How does it test multiple operators from one device?
Two ways: connect up to 4 physical SIMs through the SIM Multiplexer add-on, or use native eSIM (SGP.32) with up to 10 operator profiles. In both cases an automatic rotation engine switches the active profile between test runs — no roaming, no manual SIM swaps.
What's the difference between the indoor and outdoor versions?
The indoor probe is a COTS smartphone in a secure casing — lowest cost, CE/FCC certified. The outdoor probe is a rugged IP67 unit (−40→+85 °C, 7 antennas, PoE, ATEX option). The same Neutroon agent and metrics run on both.
What does the Watchdog measure?
Passive RF scan (RSRP and RSRQ for every detected operator, no SIM), serving-cell RF (SINR, PCI, CQI with a SIM attached), active performance (DL/UL throughput, latency, jitter, packet loss, availability), voice quality (VoLTE/VoNR call-setup, drop rate, eMOS) and real-device application QoE.
What is national-SIM compliance?
Some markets require a domestic operator profile to attach lawfully. The Watchdog supports national-SIM compliance so tests attach in-country where probes without it are rejected.
Which industries use it?
Mobile operators, neutral-host/towercos, ports/mining/logistics, utilities/energy/transport, airports and critical infrastructure, defense, and regulators.
How is it different from drive testing or phone-app tools?
It runs continuously and unattended across indoor, outdoor and rugged-outdoor form factors, adds real-device app QoE, and tests every operator via the SIM Multiplexer or native eSIM — at a far lower cost per monitored point than premium drive-test systems.
Is it available now?
Yes — the Assure tier is in production. Spectrum sensing (Sense) arrives Q3 2026, SDR protocol decode (Decode) Q4 2026, and ML signal classification (Intelligence) in 2027; we are already looking for early adopters for Sense, Decode and Intelligence.
