Overview

• Discover the invisible wireless world around you with Network Survey.

• This powerful, open-source Android application empowers you to effortlessly log, analyze, and visualize the signals that keep us connected.

• Whether you are troubleshooting a connection, conducting research, or simply curious about the airwaves, Network Survey turns your device into a sophisticated diagnostic tool.

Comprehensive Signal Tracking

• Capture precise, detailed records of Cellular networks, Wi-Fi networks, Bluetooth devices, and GNSS constellations.

• Monitor signal strength, network configurations, and device data in real time.

• Save your data locally in versatile GeoPackage or CSV formats for deep offline analysis.

Real-Time Streaming and Integration

• Broadcast your network findings live using MQTT or gRPC protocols for immediate remote monitoring.

• Seamlessly integrate your data stream with external systems and custom dashboards.

• Access setup guides for gRPC servers (via GitHub) and Mosquitto MQTT brokers to get started quickly.

Advanced Cellular Insights

• Log detailed performance data for your active serving cell as well as surrounding neighbor cells.

• Isolate and analyze specific cellular protocols by temporarily locking your device to your desired network mode.

• Utilize built-in diagnostic calculators to instantly convert LTE Cell IDs to eNodeB and Sector IDs, or LTE PCI to PSS and SSS.

Specialized Features and Privacy

• Enable Call Detail Record (CDR) logging to automatically document call events to a organized CSV file.

• Rest assured with transparent privacy practices; background location permission is used solely to allow the app to start tracking immediately upon booting your device.

FAQ

Q: In what formats can I save my surveyed network data for offline analysis?

A: To make your offline analysis as smooth as possible, Network Survey allows you to save your logged data locally on your device in either GeoPackage or CSV formats. These versatile configurations make it incredibly easy to import your records into various geographic information systems (GIS) or spreadsheet software for deeper inspection later on.

Q: Can I monitor my network data remotely in real time?

A: Yes, you absolutely can. The app features powerful real-time integration capabilities, allowing you to broadcast your live network findings to external systems. You can use either the lightweight MQTT protocol or the high-performance gRPC framework to stream your data directly to custom dashboards or remote monitoring tools.

Q: Where can I find resources to set up my own gRPC server or MQTT broker for data streaming?

A: Getting your streaming environment up and running is quite straightforward because the project provides excellent integration guides. You can access detailed setup instructions for gRPC servers through the Network Survey Messaging repository on GitHub, and you can find comprehensive setup resources for the popular Mosquitto MQTT broker online to quickly start receiving your live feeds.
