Wi-Fi Positioning
Wi-Fi Positioning is a technique that uses Wi-Fi signals to determine the geographic location of a device, typically by measuring signal strength from nearby access points and comparing it to a database of known Wi-Fi networks. It operates similarly to GPS but leverages existing Wi-Fi infrastructure, making it effective for indoor environments where GPS signals are weak or unavailable. This technology is commonly used in location-based services, indoor navigation, and asset tracking applications.
Developers should learn Wi-Fi Positioning when building applications that require accurate indoor location tracking, such as in shopping malls, airports, or large office buildings, where GPS fails. It's also valuable for creating location-aware apps, geofencing, and IoT devices that need to operate in urban or dense environments with abundant Wi-Fi networks. Understanding this concept helps in implementing hybrid positioning systems that combine Wi-Fi with other technologies like Bluetooth or cellular for improved accuracy.
