Frequently Asked Questions

Anchors

Is there a limit on how many anchors I can add to the system?

You can add as many anchors as you need to the system. Although the server has a limit on how much data it can manage, it is possible to add an additional server to the system if needed.

How do anchors communicate with the server?

There are two ways in which anchors can communicate with the server: data transmission is enabled through Wi-Fi or Ethernet cables.

What are the power options for anchors?

Eliko RTLS anchors have Ethernet and Wi-Fi connectivity options.

What is the coverage of anchors?

An anchor’s range is up to 70 meters, so with 4 anchors you can cover up to 50×50 meters (~2500m2). You can expand the tracking area by installing additional anchors in the new area.

How many anchors do I need to cover the area? Are there any rules for calculating the number of anchors needed to cover a specific area?

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 them 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.

What are anchors?

Anchors are reference devices that are placed around the tracking area. They enable you to measure the distance from a tag to calculate its location coordinates. Anchors are installed on the walls, ceiling or other support structures.
