Wi-Fi based location systems

Wi-Fi-based location systems determine a device’s position by analyzing signals from nearby Wi-Fi access points, which are fixed routers or transmitters. When a device connects or detects these signals, its location can be estimated by measuring the strength and timing of the signals relative to known access point locations. This allows for indoor positioning where GPS signals are weak or unavailable, such as in shopping malls or airports. These systems are cost-effective, utilizing existing Wi-Fi infrastructure, and provide fairly accurate position data for navigation, asset tracking, or context-aware services within indoor environments.
