Precise indoor navigation requires innovative technologies that can adapt to the specific challenges of these environments. Here are some key technologies that can be used for indoor navigation:

QR Codes:

QR codes are two-dimensional barcodes that can be scanned by smartphones or cameras. Indoor navigation using QR codes requires certain codes to be placed in relevant locations. Users scan these codes to receive instructions or location information. QR codes offer a simple and cost-effective solution.

Bluetooth (BLE):

Bluetooth Low Energy (BLE) beacons are small, energy-efficient devices that continuously emit signals. Smartphones and other devices can receive these signals and determine the exact position in the room based on the signal strength. BLE is particularly suitable for precise indoor localisation and navigation.

WLAN (Wi-Fi):

WLAN-based indoor navigation utilises existing Wi-Fi networks in buildings. The position of a device can be determined by triangulating the signal strengths of different Wi-Fi access points. WLAN is well suited to larger areas and offers a greater range.

RFID (Radio-Frequency Identification):

RFID technology uses radio frequencies to exchange data between a reader and an RFID tag. In indoor navigation systems, RFID tags can be placed at strategic points and readers can recognise the tags to determine the position. RFID is particularly suitable for precise and cost-efficient indoor localisation.

Inertial navigation systems:

Inertial navigation uses sensors such as gyroscopes and accelerometers to track the movements of a device. This technology is good for determining directional changes and distances, but can be prone to cumulative errors.

Ultrasonic technology:

Indoor navigation systems can use ultrasonic waves to accurately determine the position of devices. By measuring the time of flight of ultrasonic signals, precise distances can be calculated. Ultrasound is well suited for environments where other technologies may be limited.

Selecting the optimal technology depends on several factors, including accuracy requirements, cost, infrastructure and specific venue requirements. A combination of several technologies is often used to ensure comprehensive and reliable indoor navigation.
