Cell Signal Monitor

Cell Signal Monitor

GSM signal level on Android

This is a program designed for monitoring and logging GSM network signal levels. It supports both GSM and UMTS standards, providing detailed tracking capabilities for network performance analysis.

Please note that neighboring cells are only displayed when operating within a GSM network. The graph visualizes the dynamic changes in signal strength for the current cell as well as surrounding base stations, specifically for GSM connections.

This tool is particularly useful for analysis in areas with weak or unstable signal reception, helping users understand and evaluate coverage quality in challenging environments.
