Reliable

With the Eliko UWB RTLS you can say goodbye to positioning reliability gaps even in challenging industrial environments. More than seven years of development and piloting in real environments have already been put in to enhance the reliability, robustness, and stability of the system. Additionally, UWB itself has superior performance in multipath and reflections, penetrates obstacles and has no interference issues with other radio waves.

Tailored to your needs

The highly flexible system enables you to configure it based on your requirements. You can choose the accuracy level, refresh rate, communication mode, system setup, features, integration, support level and more to tailor it to your use case needs. The system’s state-of-the-art localisation method allows more options for advanced configurations than similar solutions on the market. We have also customised the standard hardware.

Cost-efficient

We ensure that you get a reliable positioning network with a fair value. Eliko’s system is based on a unique UWB design that enables us to optimise the anchor count. Additionally, we can combine multiple positioning methods in different places of the tracking area. As a result, with the Eliko UWB RTLS system you may need up to half the infrastructure hardware than is typical to ensure the precision you need. This also lowers the installation and maintenance costs.

How it works

Watch our introductory video about how the Eliko UWB RTLS works.

The Eliko UWB RTLS system consists of anchors, tags, a server and the ranging software. The mobile tag uses ultra-wideband radio technology to communicate with the anchors that are placed around the tracking area. The tag chooses anchors based on self-learning algorithms from which the distances are calculated. Based on the distances measured, the coordinates are calculated in the server using state-of-the-art ReCalc and self-learning algorithms.

System components

Key components of the Eliko RTLS system are anchors, tags, a server and the RTLS software. Read below about how it all comes together in a standard setup or the first development kit.

Eliko RTLS Server

The Eliko RTLS Server is an Ubuntu Linux machine with multiple roles.

  • It creates the RTLS anchor network;
  • Calculates coordinates;
  • Connects the Eliko RTLS with any third-party information system through API commands;
  • Hosts the Eliko RTLS Manager.

Eliko RTLS Manager

The Eliko RTLS Manager is an easy graphical user interface to provide a clear overview of the system.

  • You can use it for initial system setup, basic configurations, and visualisation.
  • Additionally, you can access and manage the system through a well-documented representational state transfer (REST) interface. It provides much broader options for advanced configurations.

Optional Add-ons

We use the following add-ons to set up the system:

  • PoE switch
  • PoE extender
  • Wi-Fi repeater
  • USB charging dock
  • Different mounting options for tags and anchors

Key features

1

Choose an accuracy level

You can set up the system based on your accuracy needs starting from 3 cm down to room-level proximity. Accuracy is subject to anchor count: increase or decrease the density of anchors based on your accuracy needs and environment.

2

Set update rates

You can set suitable update rates for your tags from once per minute up to 300Hz (Hz- times per second). The system enables you to set different update rates for standing and moving.

3

Create geofences

The geofence feature enables you to create digital zones around moving objects and people or static areas. So you can use the system for applications that keep employees safe by creating digital safety zones and anti-collision systems. Geofences also enable you to trigger other events, such as stopping a machine or sending a notification about an arrival at the production area.

4

Trigger events

You can use the tags for applications where you need to trigger real-time notifications. For example, send alarm notifications to tags to flash LED on the tag, to make the tag vibrate or to trigger external devices. With its two-way communication and absolutely lowest latency, Eliko UWB RTLS is suitable for demanding applications.

5

Configure through API

The system’s API friendliness makes it ideal for developers demanding flexibility. It’s a TCP / IP-based connection with API commands in NMEA standard data format, which enables to integrate it into any other system. Learn more from the API overview.

“Our main challenge before using the Ultra-Wideband tracking system was tracking in darkness to project the lighting precisely on the dancer. The infrared systems for artists on stage can easily get confused when we need to track more than one target, so we were searching for something not visual or infrared. We liked that Eliko’s UWB-based RTLS had a very high refresh rate and was very accurate.”

Eric Brucker
Lead Engineer at the Curtis R. Priem Experimental Media and Performing Arts Center (EMPAC) in Troy, New York

“We studied several real-time tracking systems with different technologies and, in the end, we decided to implement the UWB RTLS from Eliko. For us, it had the best location tracking results, the easiest configuration and the best cost-efficiency ratio.”

Frequently asked questions

How many anchors do I need?

The number of anchors you need to cover the tracking area heavily depends on the environment of the area, as conditions are rarely ideal. Therefore, we cannot guarantee any one-size-fits-all rule. The best way to find out the approximate number of anchors needed for your tracking area is to contact our RTLS experts and provide us with the floorplan of the area and some pictures if possible. The preliminary setup for tracking can then be drafted based on the information provided.

In general, for 2D positioning, the minimum number of anchors needed is 3. However, we recommend 4 anchors for additional reliability and optimal precision. For 3D positioning, at least 4 anchors are required. With 4 anchors you can cover about 50×50 m (~2500 m2) in ideal conditions. In a difficult non-line-of-sight (nLoS) situation more anchors are used to provide the best precision possible. If your layout does not allow a standard easy setup, contact us for guidance.

How does the UWB technology work?

Like Bluetooth and Wi-Fi, ultra-wideband (UWB) is a short-range, wireless communication protocol that operates through radio waves. But unlike its counterparts, it operates at very high frequencies — a broad spectrum of GHz frequencies — and can be used to capture highly accurate spatial and directional data.

Does Eliko RTLS work both indoors and outdoors?

Eliko RTLS, which uses ultra-wideband (UWB) radio technology, works both indoors and outdoors. Therefore, while primarily an indoor positioning system, it is also suitable for temporary outdoor applications. The Wi-Fi anchors enable the quick and convenient setup of the system without having to worry about cabling.

For permanent outdoor installations, UWB regulations should be checked, as such installations may be prohibited depending on the country or region. Learn more about the current status of regulations from UWB Worldwide regulations or contact us for in-depth information about UWB regulations.

The required level of water resistance should also be considered when planning an outdoor application.

How much does it cost?

We ensure that you get a reliable positioning network with a fair value. Eliko RTLS is based on a unique UWB design that enables us to optimise the anchor count. Additionally, we can combine multiple positioning methods in different places of the tracking area. As a result, with the Eliko UWB RTLS system you may need up to half the infrastructure hardware than is typical to ensure the precision you need. This also lowers the installation and maintenance costs. The infrastructure costs start from 2 EUR per m2, depending on the tracking environment and accuracy needs.

What is the difference between ToF and TDoA methods?

ToF – time-of-flight, sometimes called ToA – time-of-arrival.
TDoA – Time difference of arrival.

Both the ToF and TDoA methods rely on measuring the time it takes for the radio waves to travel a certain distance in the air. The difference between ToF and TDoA lies in the distances we actually measure and how we use them to calculate the position of the tag.

Read more about their pros and cons on our blog post:
