Indoor navigation is the indoor version of google maps where individuals can navigate from point A to point B in an indoor setting. This includes apps on smartphones that provide users with a floor map and interactive step-by-step blue dot navigation.

Individuals can search for locations and their position will be constantly updated. Indoor navigation systems are used in various buildings such as hospitals, malls, airports, museums, offices, and stadiums.

With the help of indoor navigation, users can find specific gates at an airport, stores, elevators, and hospital wings.

As a result, this improves a customer’s experience because their visit will be less stressful. No one wants to panic that they’re going to miss their flight at an airport due to not being able to find the right gate.

Furthermore, this navigation system decreases staff costs as customers will be less reliant on asking for directions and use their smartphones instead.

Different Types Of Indoor Navigation Systems

WiFi

This indoor navigation system depends on tags that are WiFi transmitters. Various WiFi access points in a building receive these transmitters. The time and strength of each reading are calculated by the indoor navigation systems.

Despite being effective, WiFi systems require a range of access points to remain accurate. Therefore, it can be less cost-effective and energy-efficient than other systems.

Ultra Wide-Band

An ultra wide-band or UWB system works by transmitting a wide pulse over a GHz of the spectrum while listening for chirps from ultra wide-band tags. A quick and immediate burst is created to allow ultra wide-band readers to report a specific time measurement.

Acoustic

Acoustic indoor navigation systems work similarly to UWB. The only difference is instead of radio signals, it relies on sound. Receivers detect the sound and locate the tags.

Infrared

Infrared utilizes infrared light pulses to discover signals within a building. In this indoor navigation method, infrared receivers are installed in every room. Whenever an IR receiver reads a device, the IR tag pulses. Infrared systems are installed in the ceiling which may cause issues in open spaces where receivers will read the same pulse without identifying which reader is closest.
