• Background operation indicators

Technical Details:

• Supports 4G LTE networks

• Collects RSRP (Reference Signal Received Power)

• Measures RSRQ (Reference Signal Received Quality)

• Tracks SINR (Signal to Interference + Noise Ratio)

• Records CQI (Channel Quality Indicator)

• Captures cell information (eNodeB ID, Cell ID, TAC, PCI, EARFCN)

• GPS location tracking

• Timestamp recording

Perfect for:

• Network Engineers

• RF Technicians

• Coverage Testing

• Network Optimization

• Signal Quality Analysis

• Coverage Mapping

• Network Troubleshooting

• Site Surveys

The app requires the following permissions:

• Location access (for mapping signal strength to locations)

• Phone state access (for reading cellular signal information)

• Storage access (for exporting data)

Note: Continuous use of GPS running in the background can dramatically decrease battery life. The app includes options to customize measurement intervals and background operation to help manage battery usage.

For optimal results:

• Enable high-accuracy location services

• Grant all requested permissions

• Keep the device in a stable position during measurements

• Consider device orientation when analyzing signal strength

Regular updates and improvements are planned to enhance functionality and user experience. Your feedback is valuable in making this tool even better!
