1月30日的CellInfo: 5G Signal & Maps应用程序分析

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 CellInfo transforms your device into a precise, professional-grade mobile network analysis tool. Download now and map your real signal experience with unmatched accuracy! Professional 5G NR Analysis Tools CellInfo leads the industry in providing professional-grade 5G NR signal metrics directly on your Android device. Our advanced measurement suite includes: CSI-RSRP, CSI-RSRQ, CSI-SINR: Channel State Information measurements that provide more accurate signal analysis than traditional SS-RSRP, especially for beamformed 5G connections (Android 10+). CQI Report: Per-subband Channel Quality Indicators (0-15 scale) showing quality distribution across frequency subbands, available on Android 12+ devices. CQI Table Index: Real-time modulation scheme indicator showing whether your device is using 64QAM (Table 1), 256QAM (Table 2), or 1024QAM (Table 3) for maximum throughput (Android 12+). 5G NR Timing Advance: Precise microsecond-level timing measurements with automatic distance calculation to the serving cell tower, essential for RF optimization (Android 14+). These professional metrics are essential for RF engineers, network planners, and enthusiasts who demand the most accurate and detailed 5G network analysis available on mobile devices.
