Development of a mobile application for measuring the signal of a cellular network

Vegatel approached ItFox with the task of developing a mobile application to measure the quality of cellular signal in hard-to-reach areas. The application was intended to automatically scan available networks and cell towers, providing users with information about signal quality. This would allow them to identify weak signal zones and contact Vegatel for improvements. The main challenge was obtaining deep data from the phone's GSM module, as users only see the general signal level, while specific digital indicators are required for analysis.

Implementation
ItFox chose to develop the application natively for the Android platform using Kotlin, as this was the only way to access all necessary APIs for signal analysis. The application provided users with detailed analytics, including noise and interference levels. The team developed the interface based on detailed feedback from the client and created several prototypes. After verifying the hypothesis about data retrieval, the development of functionality began: screens with a list of stations, a map of towers, and marketing elements. During the testing phase, client-provided cases were taken into account, ensuring high quality and reliability of the application. After successful testing, the application was published on Google Play.

Result
The cellular signal measurement application received a wide market response, with over 100,000 downloads and more than 5,000 positive reviews. This indicates high user satisfaction and the success of the offering. The application became an important tool for Vegatel, allowing them to attract new customers and increase sales. Users gained a convenient way to find information about nearby cellular towers and options for improving signal quality, contributing to the growth of Vegatel's customer base.
