Wi-Fi Geolocation
Wi-Fi Geolocation is a technique for determining the physical location of a device by analyzing nearby Wi-Fi access points, such as their signal strength, MAC addresses, and known positions. It works by comparing detected Wi-Fi networks against a database of access point locations, often using trilateration or fingerprinting methods. This technology enables location-based services without relying on GPS, making it useful indoors or in urban areas where satellite signals are weak.
Developers should learn Wi-Fi Geolocation when building applications that require indoor positioning, such as navigation in malls, museums, or airports, or for enhancing location accuracy in urban environments where GPS is unreliable. It's also valuable for IoT devices, asset tracking, and analytics that depend on precise location data without constant GPS usage, reducing battery drain and improving performance in dense areas.
