Real-Time Locating System (RTLS)

Intro

Production and Logistics Rely on Real-Time Location With UWB Technology

KINEXON RTLS is a key technology to optimize and automate industrial processes. KINEXON’s Real-time locating system (RTLS) is based on Ultra-Wideband (UWB) technology and is designed for the most challenging indoor and outdoor industrial environments. Therefore it is characterized by the highest precision and maximum robustness. Quick and easy setup and installation ensure efficient scalability — even in large factories and warehouses.


KINEXON Industry tags, anchor and sensors

UWB-Based RTLS Is the "GPS for the Industry“

The digital transformation in production and logistics is progressively gaining ground. However, intelligent process optimization and automation in terms of IoT (Internet of Things) require accurate knowledge of the position, status, and ID of all assets at all times.

Many real-time tracking technologies have significant disadvantages; for example, GPS localization is not precise enough and is limited to outdoor use only. Even WiFi and Bluetooth/​BLE positioning do not achieve the required precision and connection stability.

Our UWB localization technology always wins in these aspects. It locates machines, people, goods and much more precisely, stably and scalably.

KINEXON is a pioneer in the field of UWB real-time locating systems. By combining two decisive functions, we offer the perfect solution for industrial, logistics and intralogistics processes:

  1. First, the collection of all relevant proprietary data such as 3D position (x, y, z), the status of objects as well as their ID, acceleration, alignment, and pressure.
  2. Second, bidirectional data transmission so that objects can send data to each other (e.g. temperature or battery status) and receive data (e.g. commands).

KINEXON RTLS visualizes and networks the spatial context of your assets and makes highly efficient industry and logistics 4.0 solutions possible thanks to the latest precise, simple, robust, and smart UWB real-time locating technology.

The Components of Our UWB Real-Time Locating System (RTLS)

190626 Logistik Usecase with Font Website

Our system consists of three main components:

The tags are attached to all objects or persons that are to be located and tracked. These include parcels, carriers, materials, tools, vehicles, or workers.

The anchor network consists of anchors permanently installed in the respective room, which form a calibrated network. They serve as reference points for the tags. They are also connected to a local or external RTLS server. It processes the time stamps of the received pulses with the lowest possible latency as well as the exact position, status, and ID information and provides the data using various standardized APIs.

UWB pulses transmitted from the tags to the anchor network ensure that the exact positions of all objects and persons within the RTLS are accurately determined. Additional information such as temperature or battery status of an asset can be transmitted to and from the sensors without the need for a separate WiFi.

RTLS With High-Precision UWB Technology

UWB technology is based on the combination of very short pulses moving at the speed of light. The band width of at least 500 MHz allows an exact measurement of the arrival time and thus a high-precision determination of the positions. UWB technology does not interfere with other technologies because the bandwidth (3.25 — 4.75 GHz and 6.25 — 6.75 GHz) differs from WLAN and ISM channels, and the signal strength is very limited. Anchors can cover distances of up to 200 m if there is visual contact.

190627 KINEXON System Methoden TWR

Two-Way Ranging (TWR)

TWR offers maximum precision and positional stability. The anchor sends a UWB signal and the sensor returns it. The distance between the anchor and the sensor is determined by the time required for the UWB pulses. A position can be determined as soon as the distance of a sensor relative to different anchors is available. The TWR method is mainly used for the localization of workers, tools, and navigation of driverless transport systems.

190627 KINEXON System Methoden T Do A

Time-Difference of Arrival (TDoA)

The TDoA position determination is characterized by the lowest energy consumption among the available methods on the market. The sensor transmits a signal which is received by the anchors at different intervals relative to the distance of the sensor. The position of the sensor is determined by the interval differences. Positioning with TDoA is mainly used for the localization of a large number of objects.

190627 KINEXON System Methoden Ao A

Phase-Difference-of-Arrival (PDoA)

The PDoA method (also angle-of-arrival method”, AoA) evaluates the phase difference between the received signals at the two antennas of an anchor. Based on this, the angle of the signal relative to the anchor is calculated and thus the position of the sensor can be determined. PDoA is generally used for position determination when there is a limited infrastructure and additional information is to be used by the sensor signals.
