Building a map without accompanying GPS tags or manual inputs to interpret the data coming from Wi-Fi routers is virtually impossible. Addressing the issue, the Korea Advanced Institute of Science and Technology (KAIST) is all set for a new method to develop a map from Wi-Fi radio signals without GPS tags. Employing software embedded in Smartphone apps to upload a Wi-Fi fingerprint, the new mapping system links the geographic coordinates of home and office addresses to the Wi-Fi fingerprints gathered by the Smartphones.
Furthermore, the mapping system combines the information gathered from different users to create a collective Wi-Fi radio map of a particular geographic area. Developed to become the basis of indoor navigation or indoor location-based services, the mapping from Wi-Fi “Fingerprints” could bring about a revolution in indoor navigation.
