A telecommunications company wanted to streamline their fiber optic network testing process using mobile devices. A Xamarin-based cross-platform native mobile application was developed to allow 2,000 technicians to conduct over 100,000 fiber optic tests in real-time. The application integrated with cloud services and Bluetooth hardware to transfer test results seamlessly from the field to remote engineers for analysis and troubleshooting. This helped the client significantly reduce the time required to detect and resolve network issues.
