Air-Go RTLE (Real Time Location Engine) SDK will enable IOS and Android apps to develop indoor maps that will assist and guide visitors inside public and private indoor buildings (shopping malls, airports, museums, exhibition centers, factory plants, schools). It provides a variety of helpful features such as indoor localization, finding destination, calculating shortest path, guiding and showing paths, storing locations, giving feedback to building management, entering surveys for restaurants and coffee shops or finding nearest services.
