Geofencing
Geofencing is a location-based service that uses GPS, RFID, Wi-Fi, or cellular data to define virtual geographic boundaries, known as geofences. It triggers automated actions, such as notifications or data logging, when a device enters or exits these predefined areas. This technology is widely used in mobile apps, IoT systems, and logistics for real-time location tracking and context-aware functionality.
Developers should learn geofencing to build location-aware applications that enhance user engagement, automate processes, and improve security. Key use cases include mobile marketing (sending push notifications when users enter a store), fleet management (tracking vehicle movements), and smart home automation (adjusting settings based on user proximity). It's essential for apps requiring real-time spatial awareness and personalized experiences.
