Why Benchmarking Gets Done Wrong
Most network benchmarking exercises fail for one of two reasons: they measure the wrong things, or they measure the right things but can't communicate them to decision-makers. A drive test that produces 40GB of raw NEMO logs is not a deliverable — it's a starting point.
A useful benchmark answers a specific business question: Is this network ready for autonomous vehicle operations? Does coverage meet the SLA in building zones C and D? Which vendor's configuration is performing better in the mmWave sectors?
What to Measure
- RSRP (Reference Signal Received Power): The foundational coverage metric. Target > -105 dBm for basic data, > -90 dBm for mission-critical applications.
- SINR (Signal-to-Interference-plus-Noise Ratio): The quality metric. Low SINR kills throughput even in strong coverage areas. Target > 10 dB for reliable high-throughput operation.
- Downlink/Uplink Throughput: Measured under controlled load conditions. Always specify the test methodology — peak throughput means nothing without load context.
- Handover Success Rate: Critical for mobile applications. A single failed handover drops an AGV connection and can halt production.
- Latency (RTT): For time-sensitive applications — robotic control, AR, remote surgery — measure round-trip time under realistic traffic conditions, not idle ping.
- Coverage Holes: Zones with RSRP < -115 dBm or no service. Map these against operational areas to determine business impact.
Vendor-Agnostic Comparison Framework
When comparing vendors or configurations, normalize your data. A vendor running at higher transmit power will always show better RSRP — that tells you nothing about system efficiency. Normalize to equivalent EIRP and compare SINR, handover performance, and throughput-per-PRB.
SIGMET's benchmarking module automates this normalization and generates side-by-side vendor scorecards that are defensible in procurement discussions.
Communicating Results
- For engineering teams: CDF plots, heatmaps, per-sector KPI tables, and failure mode analysis.
- For operations managers: Coverage percentage by operational zone, uptime metrics, and trend lines.
- For executives: A single-page scorecard: green/yellow/red by KPI category, business risk summary, and recommended actions with estimated cost and timeline.
The most technically perfect benchmark report is worthless if a VP can't read it in 90 seconds and understand what needs to happen next. SIGMET generates all three report formats automatically from the same underlying data.
