Either the data calculated on the smartphone can be sent to the backend, or a server-based solution can be used. The position data can also be used for analysis purposes. In order to realize an indoor navigation, a client-based solution is required. Especially in airports, railway stations, shopping centres, hospitals, museums, offices and industrial complexes, an indoor navigation app can significantly improve the experience for visitors and employees. An indoor navigation solution makes sense wherever complex structures are to be found. Indoor navigation is a popular application of positioning using Wi-Fi. Sensor fusion – the use of smartphone sensors – can further improve accuracy. The accuracy of Wi-Fi used for indoor positioning varies from five to 15 meters – depending on the preconditions. ACCURACY OF WI-FI FOR INDOOR POSITIONINGĪccuracy depends on multiple factors, for example the number of available networks, reflections for example in corridors and last but not least shielding through walls, ceilings and your own body. When a server-based solution is applied, no app is required, all Wi-Fi capable devices are detected by the infsoft Locator Nodes and Wi-Fi tracking is possible. Optionally, the position data can be sent to a server for further processing. A smartphone app calculates the current position based on the signal strength and MAC address. The strength of the Wi-Fi signals (received signal strength indication, RSSI) and the MAC address (media access control) are significant.įor a client-based solution, the position is determined directly on a mobile device. restrictions for server-based detection via Wi-Fi TECHNOLOGYįor positioning, the so-called fingerprinting method is used. In order to detect smartphones and other mobile devices, their Wi-Fi function has to be switched on, a connection to the network is not necessary, but has a positive influence on latency times and allows the unambiguous correlation of devices. If a server-based solution is more suitable for the project, infsoft Locator Nodes can be installed throughout the building. The calibration of position determination works with a one-time reference measurement in the run-up, where the signal strength of the Wi-Fi networks is determined. For example, existing customer hotspots, cash register systems and routers from shops can be used. In most cases it is easy to install a Wi-Fi positioning system, since Wi-Fi access points already exist in many buildings. SETTING UP AN INDOOR POSITIONING SYSTEM USING WI-FI An additional advantage compared to GPS is the possibility to determine the current floor level. A good alternative is indoor positioning using Wi-Fi. Positioning using GPS does not work reliably inside buildings as there is no visual contact with the GPS satellites. ![]()
