Field notes
The phone scans Bluetooth advertisements and Wi-Fi beacons in short duty cycles, then scores hits against vendor identifiers such as company IDs, service UUIDs, address prefixes, and payload tags. The companion radio adds an external antenna and faster Wi-Fi sweep; its four antennas are sampled in sequence, with the strongest signal selecting a front/right/rear/left sector. The page shows a phone-only scan and describes a per-unit calibration certificate; the performance figures are the site's own report.
