Abstract: We spend 90% of our time indoors. Buildings became larger and more complex (international airports, subway stations, shopping malls or hospitals for example). Our behaviour has changed. Given the possibilities of ubiquitous technology, we are used to finding out what our position is whenever we want – so far almost exclusively outdoors, however. We have little data on where and how people move indoors. There are various technologies for Indoor Positioning, but none of them dominates the market because of the very different requirements of the large range of applications. With Bluetooth Low Energy (BLE or Bluetooth Smart), a new technology has entered the market, and using it for Indoor Positioning is currently at the forefront of developments. Common positioning methods based on BLE include lateration, angulation, fingerprinting and proximity solutions. Most of them are based on the Received Signal Strength Indicator (RSSI). The RSSI correlates with the distance between transmitter and receiver antenna. However, the link is not as continuous as mathematical models suggest. The RSSI is influenced by many variables, some of which can be controlled and others not. This paper sums up general BLE positioning methods and the challenges they face with RSSI. Keywords: Indoor Positioning, Bluetooth Low Energy, Received Signal Strength Indicator, beacon Published Online: 2016/06/29 07:05:59 Object Identifier: 0xc1aa5576 0x0033fe91 Rights:https://creativecommons.org/licenses/by-nd/4.0/
GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.
