CellInfo – The Ultimate Mobile Signal Analysis & Coverage Tool 📡

CellInfo is the essential diagnostic app for anyone who needs accurate, engineering-grade mobile network data. Whether you're an RF engineer, field tester, or power user, CellInfo replaces guesswork with real measurements of signal strength, network type, and coverage quality.

I. Real-Time Diagnostics

Get instant access to raw technical metrics across all major technologies: 5G NR (SA/NSA), 4G LTE/LTE-A, WCDMA, GSM, and CDMA. The dashboard exposes the core values used by professionals:

• RSRP – true signal strength
• RSRQ – signal quality under interference
• RSSNR – noise level
• RSSI & ASU readings
• Full MCC, MNC, TAC/LAC, Cell ID, eNB/gNB info
• Dual-SIM support with parallel monitoring
• Background monitoring via a lightweight notification

II. Historical Stats & Expert Analysis 📈

Track long-term behaviour to understand real coverage performance:

• Network Type Statistics – see the percentage of time spent on 5G, 4G, 3G, and more
• Expert View – full band and aggregation analysis
• Carrier Aggregation detection (e.g., B20+B3)
• MOCN identification for shared networks
• 5G NR band usage distribution (e.g., n1, n28, n78)

III. Signal Mapping & Drive Testing 🗺️

Visualise signal strength in real time:

• Real-time logging generates a dynamic drive-test style map
• Points are auto-coloured using industry dBm ranges (Excellent to Poor)
• Tap any map pin to view: Cell ID, eNB:ID, PCI, MCC/MNC, Band, RSRP/RSRQ/SNR, and precise GPS coordinates
• Load supported CSV files to compare past logs and historical coverage

IV. Diagnostics, Processing & Export 🔬

CellInfo includes a full suite of testing and professional data tools:

• Network Diagnostics Screen – quality scoring (e.g., 89/100) based on stability, latency, and speed
• Speed Test, Ping Test (Latency/Jitter), DNS Test, Port Scan
• WiFi + Cellular status shown together for failover awareness
• Advanced CSV Processing – filter by MCC+MNC, Cell ID, PCI, Band; auto-summaries for strongest/weakest per cell
• Flexible Logging Modes for custom data capture
• Export to CSV and CLF 3.0 formats
• Built-in upload support for OpenCellID and BeaconDB
