When it comes to wayfinding in indoor environments, the Global Positioning System (GPS) is not competent enough to give an accurate position of where the user is due to the obstruction of signal transmitted between satellite and mobile device. With the rise in usage of mobile devices and many technological advancements including the emergence of 5G, the importance of developing a capable indoor and outdoor localization system has increased. Having knowledge of the occupancy level of buildings and shopping malls has become a very useful tool for people to plan when is the best time to enter malls during the on-going/recent circuit-breaker period. This also provides aid in creating energy efficient buildings. In this project, the author aims to develop a smartphone application that makes use of GPS-based outdoor navigation and then switch BLE-based navigation when the user enters an indoor environment. This is done by using Estimote Proximity iBeacons as access points to measure Received Signal Strength (RSS) between the mobile device and iBeacon. By the end of the development, an experiment is conducted by simulating a user navigating from an outdoor starting position to an indoor environment in which the app will indicate to the user which room the user is in and store the number of occupants in its data base.
