Signal Sense

Signal Sense is a diagnostic suite for technicians, engineers, and power users. Gain deep visibility into cellular, Wi-Fi, and GNSS environments with real-time metrics, historical logging, and advanced network analysis.

📡 CELLULAR MONITORING (5G, LTE, NR)
Direct modem interfacing for unparalleled mobile insight.
• Real-time Metrics: Track RSRP, RSRQ, RSSI, and SINR with high-frequency updates.
• 5G/NR Specialized Support: Capture NR CSI and SINR data (SA and NSA modes).
• Cell Identity: View PLMN, TAC, CI, EARFCN, and Band info for serving and neighbor cells.
• Multi-SIM: Full enumeration and monitoring for dual-SIM hardware.

📶 WI-FI ANALYSIS (Wi-Fi 7, 6E, 6)
Optimize local network performance and identify congestion.
• Spectrum Scanning: Visualize channel overlapping across 2.4GHz, 5GHz, and 6GHz bands.
• Detailed Stats: SSID, BSSID, Link Speed (Tx/Rx), Channel Width, and WPA3 security.
• Network Topology: Full IP details (IPv6/IPv4), Gateway, DNS, and DHCP lease info.
• Signal History: 60-second rolling RSSI charts to pinpoint dead zones.

🛰️ GNSS & SATELLITE STATUS
A comprehensive dashboard for professional satellite analysis.
• Constellations: Monitor GPS, GLONASS, BeiDou, Galileo, QZSS, and NavIC.
• Signal Strength (C/N0): View real-time signal-to-noise ratios for every satellite in view.
• Precision Metrics: Track TTFF, HDOP, VDOP, and PDOP; access raw NMEA sentences.

🛠️ NETWORK DIAGNOSTICS
• Advanced Tools: Continuous Ping (with latency history), Traceroute, and Subnet Scanning.
• Speed Test: High-performance testing via Cloudflare's global edge network.
• Data Export: Export signal logs to CSV for professional analysis in Excel or GIS software.

PRIVACY & DATA CONTROL
• Local Processing: All core signal analysis and logging happen entirely on your device. Your sensitive location and signal data are never transmitted to our servers.
• Optional Analytics: We use anonymous analytics to help improve app stability. This is opt-out by default in the settings; we respect your choice to remain invisible.

PERMISSIONS NOTE:
Signal Sense requires Fine Location, Phone, and Nearby Wi-Fi Devices permissions to access hardware-level metrics. Location is used solely on-device for cell tower and GPS data. Background notifications are used for the optional foreground monitoring service.
