Positioning Sensors for Indoor Localization
Indoor positioning can encompass a variety of technologies. Get to know different indoor positioning technologies including tips and techniques for the implementation and suitable applications.
Indoor navigation using Wi-Fi achieves accuracies of 5-15 metres. A server-based approach using Wi-Fi technology will determine the position of devices with activated Wi-Fi (e.g. smartphones, tablets) and Wi-Fi tags.
Bluetooth Low Energy (Beacons)
Beacons are small Bluetooth radio transmitters. They are suitable for both indoor navigation systems and asset tracking applications. Beacons are available in different forms, are scalable and very portable.
Ultra-wideband is defined as a short-range radio communication. The accuracy is less than 30 centimeters, which is significantly higher than with beacons or Wi-Fi. Latency times are very low and height differences can be determined precisely.
RFID is a form of wireless communication that uses radio waves to identify objects. The position of the objects to be tracked cannot be determined permanently, but only at the time of reading.
Technologies for indoor positioning can be augmented with an imaging system, e.g. cctv cameras. This can offer decisive advantages, especially in logistics and the security sector.
