Mapping From Wi-Fi "Fingerprints" Could Improve Indoor Navigation
With outdoor mapping tools widely available and generally successful (Apple’s recent mapping debacle being the exception that proves the rule), technologists are pushing forward the state-of-the-art in indoor navigation, likely to be a hot area for advances throughout 2013. This week, KAIST, The Korea Advanced Institute of Science and Technology,announced a development that definitely is a step, so to speak, in the right direction: a new method to build a map from Wi-Fi radio signals without accompanying GPS tags or manual inputs of map coordinates. Most current systems need GPS signals to fully interpret the data coming from Wi-Fi routers. Read More
