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).
