Types of Indoor Positioning Technologies

The precise indoor location of assets in a building allows for the improvement of internal logistic processes as well as personnel management, making it a vital tool for enhancing efficiency while lowering expenses. Different Indoor Positioning Systems are used for different purposes.

Fremont, CA: Even when people are not outside, accurate indoor positioning systems (IPS) based on public sensors and user consent can deliver some level of location-based information. An (IPS) is a network of devices that can be used to find persons or items in situations where GPS and other satellite technologies are inaccurate or fail completely. Multistory structures, airports, alleys, parking garages, and underground places are all examples of this. The accuracy of current IPS technologies is weak, especially in multi-level buildings. The deterioration of the GPS signal caused by the structure's concrete walls is frequently the cause.

Types of indoor positioning technologies

Bluetooth low energy (BLE)

BLE technology can detect a person's or object's general location, allowing continuous asset tracking with at least room-accurate location using BLE sensors/beacons. The Angle of Arrival (AoA) method of position calculation enables far more exact localizations, but it comes at a considerable expense in terms of sensor infrastructure and hardware. Because of the cheaper costs and ease of use, BLE and Beacons have emerged as the best indoor locating technology.

WiFi-based systems

WiFi-based systems distribute readings to several WiFi access points using WiFi transmitters as tags. These readings are used by information algorithms to calculate the source's location. Eventually, the location data is sent to a cloud environment. Systems that use WiFi and TDOA (time difference of arrival) technology provide a high level of precision m,k, but they can be costly.

UWB

Ultra-Wideband (UWB) systems use three-dimensional positioning to attain extremely high accuracy. Due to the extraordinarily wide UWB signal and the capacity to emit a very wide pulse over a GHz of spectrum, continuous, highly accurate asset tracking is conceivable. In the past, UWB-based systems have had the highest accuracy. Despite the low cost of UWB tags, due to the tags' limited ranges, every location requires at least three readers. A UWB system is substantially more expensive than a BLE solution because of this.
