CellInfo – Ultimate Signal Analysis & Coverage Tool 📡 CellInfo is the essential diagnostic tool strictly for network professionals and RF enthusiasts. We replace standard coverage bars with raw, engineering-grade measurements of signal strength, network type, and connection quality. I. Real-Time Diagnostics 📊 Instant access to raw metrics across 5G NR (SA/NSA), LTE-A, WCDMA, GSM, and CDMA. The dashboard exposes the core values used by industry professionals: RSRP – True reference signal received power (dBm) RSRQ & RSSNR – Quality and noise ratios Full Cell Identity – MCC, MNC, TAC, Cell ID, eNB/gNB & PCI Dual-SIM Support – Monitor two diverse networks simultaneously Band Info – Frequency bands (e.g., n78, B20) and ARFCN II. Carrier Aggregation & Stats 📈 Understand exactly how your device interacts with the network: Carrier Aggregation (CA): Detect combined frequencies (e.g., B3+B20) for higher speeds. Expert Stats: Track % time spent on 5G vs 4G to verify coverage claims. MOCN Detection: Identify Multi-Operator Core Networks (shared towers). 5G NR Details: Band usage distribution (n1, n28, n78). III. Signal Mapping & Drive Testing 🗺️ Your personal mobile drive-test unit: Live Heatmap: Real-time logging creates a dynamic map of your route. Visual Quality: Pins are auto-coloured by signal strength (Green/Excellent to Red/Poor). Granular Data: Tap pins to view the exact Cell ID, RSRP, and coordinates captured. History Comparison: Load CSV files to compare coverage against previous drives. IV. Professional Diagnostics & Export 🔬 A full suite of comprehensive testing tools: Connectivity Suite: Integrated Speed, Ping, DNS, and Port Scanner tests. Network Score: Automated quality scoring based on jitter and packet loss. Failover View: Monitor WiFi and Cellular status side-by-side. Data Export: Export logs to CSV and CLF 3.0 for desktop analysis. Community: Direct upload support for OpenCellID and BeaconDB. V. Engineering Extras & Advanced Logic 🧠 Exclusive features for deep analysis and battery efficiency: 5G Slicing & URLLC: Detect Android 12+ network slicing and Ultra-Reliable Low-Latency status. Total Aggregated Bandwidth: View the sum of all active carriers (e.g., "100 MHz Total"). Audio Monitor: Hands-free beeps for cell handovers, ideal for safe driving. OLED Dark Mode: True black interface to save battery during long tests. Privacy-Centric: "Fused Location" technology minimizes battery drain and keeps data on your device. Professional 5G NR Analyzers CellInfo sits at the cutting edge of 5G monitoring (Android 10+): CSI-RSRP/SINR: Channel State Information measurements capture true beamformed signal quality, offering higher fidelity than standard SS-RSRP. CQI Reports: Per-subband Channel Quality Indicators (0-15 scale) show how the network grades your connection across frequencies. Modulation Tables: Real-time decoding of the Modulation Scheme (MCS) to verify 256QAM or 1024QAM performance. Timing Advance: Microsecond-level timing measurements to calculate precise distance to the serving tower (Android 14+). CellInfo is constantly updated to support the latest Android APIs and 3GPP standards. Download CellInfo now and map your real signal experience with unmatched accuracy!
