For RF, DAS, and public-safety engineers running in-building and drive-test surveys: Site Survey Pro measures Wi-Fi and cellular properly, in one tool — not a Wi-Fi analyzer with cellular bolted on, or a signal meter that stops at bars. Real SINR, real capacity, and coverage you can prove, not just what a bar graph implies.

WHAT MAKES THIS DIFFERENT

• Real SINR, not just RSRP. Most Wi-Fi/cellular apps can't read cellular SINR at all on modern Android — they show signal strength and nothing about interference. Site Survey Pro reads it directly from the platform's own signal callback, the one surface that actually carries it. Log RSRP, RSRQ, SINR and CQI on a walk test or a drive test.

• Capacity, not just coverage. Every free Wi-Fi app shows signal strength. Almost none show channel utilization — the fraction of airtime actually busy, broadcast by the access point itself. A site at -55 dBm everywhere with 85% channel utilization has a capacity problem no signal reading will ever catch. Site Survey Pro reads it and turns it into a real capacity estimate: how much headroom is left, and roughly how much per device.

• Real PHY rate ceilings. Advertised "legacy" rates top out at 54 Mbps even on Wi-Fi 6 hardware — the real numbers live in parts of the beacon almost nothing decodes. Site Survey Pro reads the actual HT/VHT/HE capability a nearby access point advertises, so your report reflects what the hardware can really do.

• Full LTE and 5G detail. Serving and neighbor cell tracking, NSA/SA state, band and channel ID, RSRP/RSRQ/SINR/CQI, and carrier-aggregation detail where the device exposes it — including CBRS and private LTE/5G bands your device reports.

• Wi-Fi roaming and heatmaps. Track BSSID transitions across a walk and visualize coverage and signal directly on an uploaded floorplan — in-building wireless survey work without a separate scanner.

• Public-safety coverage evidence. Log FirstNet Band 14/n14 against NFPA 1225 / ERCES thresholds on an NFPA grid, classified by area (general/critical) as you walk. A useful supplement to an ERRCS survey — not a substitute for dedicated LMR-based ERRCS testing, which needs equipment no phone has.

• Export everything. PDF client reports, CSV for your own analysis, and KML/GeoJSON/GeoPackage for the GIS tools survey teams already use. A session is never locked into the app.

TWO PLANS, NO ADS, EVER

Field unlocks the complete survey toolkit: Wi-Fi and cellular signal, capacity analysis, roaming, heatmaps, threshold alarms, the client-ready PDF report, and every export format (CSV, KML, GeoJSON, GeoPackage).

Pro adds direct radio diagnostics for engineers on supported rooted hardware: band and technology locking for controlled testing, live signalling decode, and neighbour-cell reads over the modem diagnostic interface.

Both are monthly subscriptions, cancel anytime.

WHO THIS IS FOR

RF and DAS engineers doing venue, building, and in-building wireless surveys. Network and private-5G/CBRS consultants who need a client-ready report, not a screenshot. Public-safety / ERRCS teams gathering FirstNet coverage evidence. IT teams diagnosing a Wi-Fi capacity problem a signal meter can't see. Anyone who has ever wanted an honest answer for why "full bars" still feels slow.

Common uses: 5G and LTE drive test and walk test, Wi-Fi site survey, DAS and in-building wireless acceptance, CBRS / private 5G verification, public-safety (ERRCS/ERCES) coverage checks, and RF signal logging with client-ready reporting.

No ads, ever.
