Using Wi-Fi signals is a great way to accurately position connected devices throughout the world in a battery-efficient way. If done correctly, this technology can provide precise location for a wide range of connected devices, including the smallest and most resource-constrained ones. Given the proliferation of Wi-Fi access points (APs) and advances in the technology in recent years, there have also been some key challenges that must be taken into consideration before using Wi-Fi for location.
In today’s world, mobile Wi-Fi APs are the most prolific in the ‘pathological’ categorization. This encompasses APs found across cars, airplanes, buses, trains, and more. It also includes APs such as mobile Wi-Fi (Mi-Fi) devices and smartphones being used as Wi-Fi access points.
