Indoor Navigation Technologies – For Indoor GPS TrackingThis system is made possible by technologies such as Wi-Fi, Bluetooth technology, UWB (Ultra wide-band), etc. This helps users of a large facility navigate and wayfind effortlessly within the venue without having to depend on GPS, which doesn’t work accurately indoors.
Wi-Fi SignalsWi-Fi signals are used to find out the exact location and guide people to their desired location. This method is also used for ‘fingerprint’ access points to gauge signal strength and helps in detecting the wireless access point.
Light PatternsThe microchips in LEDs have been used for a light pulse to transmit the information by flicking rapidly and detect Smartphone signals to determine a precise location.
Magnetic FieldsUsing magnetic fields for positioning and navigation helps to determine the accurate location. Likewise, upgrades also help by fingerprinting through the magnetic field to create a better result as well.
RFID TagsRFID tags are used as a real-time locating system than as an indoor positioning system only. Any device which comes in range by, the RFID tag identifies them and locating them becomes easy.
Beacon / iBeaconThis system if blended with beacon technology results in identifying the exact location of a person or an asset within the facility. Beacon technology is possible through Bluetooth low energy technology, for transmitting signals and identifying the information as well. A Smartphone can detect signals and helps in tracking the assets around.Apple’s beacons are called iBeacon technology. Such beacons are used as part of an indoor navigation system due to the new audio feature.

3D Indoor Maps3D indoor maps are gaining acceptance in facilities such as health care centers, warehouses, and spaces spread over large areas and have multiple assets/people to track and render images of. A recent study explains how 3D indoor maps can be developed using Microsoft Kinect V2.0.
