RadioMonitor

RadioMonitor – A mobile signal measurement & logging (drive test) app built for telecom technicians. 📱 FULL NETWORK LOGGING • Supports 1–2 SIMs, continuously logs to a CSV file on device storage • Serving cell info: Band, PCI, EARFCN, eNodeB/Cell ID, TAC, TA, RSSI, CQI, FDD/TDD duplex, VoLTE, Roaming, carrier name • 4G LTE signals: RSRP, RSRQ, SINR, CQI • 5G NR (NSA & SA): SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP/RSRQ/SINR, NCI, gNodeB ID, NR Band, NR-ARFCN • Neighbor cells (2G/3G/4G/5G) with per-cell signal levels • Carrier Aggregation (CA): combined multi-carrier bandwidth • GPS: latitude, longitude, accuracy, speed, heading 🗺️ VISUAL MAP • Live measurement trail on the map, color-coded by RSRP/RSRQ/SINR/CQI • Replay recorded logs on the map with road and satellite base layers • Import planning site DB from CSV/XLSX: sector wedges drawn by azimuth, one color per sector • Connecting line from your position to the serving sector, with distance in meters • Match the serving cell against the planning DB, red alert when serving on a wrong PCI 📊 AUTOMATIC ANALYSIS & PDF REPORT • Per-session KPIs: average/min/max RSRP, RSRQ, SINR, % of samples within thresholds, handover count • Automatic detection of: prolonged weak-signal areas, negative SINR interference, ping-pong handovers, PCI mod-3 conflicts, 3G/2G fallback, out-of-service events • Export detailed PDF reports to Download/RadioMonitor 🚀 BUILT-IN SPEEDTEST • Ping, download & upload tests via Cloudflare servers, with bufferbloat detection • Speedtest results are automatically attached to each RF log row for later analysis ⚙️ EXTRAS • Home-screen widget for instant signal monitoring • Stable background logging with WakeLock, selectable measurement interval 1–10 s • Vietnamese / English interface, clean modern light theme Ideal for network operations engineers, RF optimization teams and site survey staff who need a fast, pocket-sized measurement tool without dedicated hardware. Permissions: Location (read cell info and log GPS coordinates), Phone/SIM state (read signal status), Storage (write log files and reports).

• Map: link line from your position to the serving sector, with live distance • Sector wedges resized to 50 m, one color per sector • Map stays smooth with large planning DB files • Serving cell card: Site – Sector – Cell name, incl. 5G NSA (NR + LTE anchor) • Session analysis (KPIs, weak signal, ping-pong) + PDF report export • Speedtest results attached to RF log rows
