Real-time tracking refers to the ability to monitor the location and status of an object or person as it happens. This technology uses GPS, cellular networks, or other communication methods to provide immediate updates. Common applications include tracking delivery vehicles, smartphones, and fitness devices. This system allows users to receive instant information about movement and changes. For example, delivery services can inform customers of their package's exact location, while fitness trackers can provide live data on a user's activity levels. Real-time tracking enhances efficiency and improves decision-making in various fields.
