Home · MNO benchmarking
SigBench is an Android app for MNO benchmark and MNO quality comparison work: log LTE and 5G in the field, record RSRP, RSRQ and SINR, and compare mobile network operators on the same streets — then keep site-visit checklists and photos on the phone.
MNO means mobile network operator — the carrier whose radio network your phone camps on. MNO benchmarking is a structured comparison of those operators using the same methods, in the same places, at around the same time. A useful MNO quality benchmark answers: who covers this corridor, who holds usable quality indoors, and who actually delivers throughput when the cell is loaded.
Marketing coverage maps are often planning layers. Field MNO benchmarking is different: you measure what a handset sees. SigBench is built for that job as a signal benchmark — not a slogan, but a log of RF and optional speed tests that roll up into operator scorecards.
Professional drive-test kits use calibrated scanners and scripted call models. They are the gold standard for acceptance testing, and they are expensive. Many site visits, cluster checks, and independent audits need something lighter: LTE benchmarking and 5G benchmarking with the device customers actually use.
SigBench logs the radio access technology in use (LTE or NR/5G) with each sample, plus serving-cell identifiers, band, and operator code (PLMN). You start capture on the Map tab, walk or drive the route, and optionally run a cellular speed test. That is enough to build an honest MNO quality comparison of who is serving a street, a rooftop, or a venue — and how that serving cell is performing.
SigBench records the same LTE/5G quantities RF engineers already use. It does measure RSRP and RSRQ (and SINR) while logging is on:
| Metric | What it tells you |
|---|---|
| RSRP | Reference Signal Received Power — received strength of the serving cell’s reference signal. Weak RSRP is coverage-limited; the Map trail is coloured by RSRP as you move. |
| RSRQ | Reference Signal Received Quality — strength in the context of interference and cell load. You can have decent RSRP and still poor RSRQ on a busy or polluted carrier. |
| SINR | Signal-to-interference-plus-noise ratio — a practical hint at whether the link can sustain a useful LTE or 5G data rate. |
| Throughput | Optional download / upload / ping tests on cellular (or Wi‑Fi for broadband). Cellular tests feed the operator benchmark; Wi‑Fi tests appear under Broadband. |
Phone chipsets report these values through Android’s telephony APIs. Treat them as consistent handset measurements for comparison, not as a substitute for a spectrum analyser or scanner-based acceptance test.
Live serving-cell readouts, an RSRP-coloured trail, local history, and optional speed tests. Sites surveys (checklists, sketches, geotagged photos, PDF/ZIP) stay on the device.
Operator scorecards rank MNOs by composite score, SINR, RSRP, RSRQ, download speed and sample volume. Hex maps show where each operator is strong or weak.
Free dashboard access is for your claimed phone’s logs. Broader country-level MNO ranking is a premium view. Either way, the method is the same: geotagged RF samples tagged by operator, not a one-off speed-test screenshot.
SigBench is a crowdsourced signal benchmark and a practical MNO field-benchmark tool for people who already visit sites. It is not a 3GPP conformance suite, a MOS voice lab, or a replacement for scanner-based drive testing when a contract requires one. Use it when you need repeatable handset LTE/5G quality in the real network, operator comparison on a map, and a survey pack you can hand to a customer the same afternoon.
A like-for-like comparison of mobile network operators using the same measurements in the same places — typically LTE/5G radio quality (RSRP, RSRQ, SINR) plus throughput and coverage. SigBench turns those samples into maps and operator scorecards.
Yes. While capture is on, the app logs LTE/5G RSRP, RSRQ and SINR, serving and neighbour cell identifiers, band, and operator (PLMN), each with a location. That is the core of the signal benchmark.
SigBench is that app on Android: RF logging for MNO quality comparison, optional speed tests, and on-device site surveys. Get it on Google Play or sideload from the homepage. There is no iPhone app — why iOS isn’t available.
Each sample records the radio technology in use (LTE or NR). You compare operators on whichever RAT the phone is actually using at that location — useful for NSA/SA 5G checks and LTE fallback, not a separate hardware probe per generation.
RF logging uses a random install ID — no name, phone number or IMEI. You can stop capture anytime. Survey photos and checklists are stored on the phone and are not uploaded with the RF stream. See the privacy policy.
