Walkbase claims 5m indoor location
Walkbase claims to have a very simple and scalable solution for indoor location that can help RF fingerprint rooms using crowd-sourced data and smart self-learning algorithms. It is building up a database of room fingerprints every time someone uses its technology in an app, Walkbase scans the room for Wi-Fi and other signals and uses the data to define a room. The self-learning algorithm can filter out less reliable information and can adjust when certain Wi-Fi access points go down or move. It claims an accuracy of three to five meters.
