5.3 Revision History

Overview

The Pozyx Anchor captures, preprocesses, and sends location data from tags to a Gateway. It has been designed for optimal Ultra-Wideband performance and comes with
robust casing options (IP20 or IP66-67), making it ideal for industrial environments.
Mounting the Anchor is straightforward with the help of three mounting brackets.
The Anchor works within the Pozyx Enterprise system and requires an infrastructure of Tags, Anchors, switches, and a Gateway to accurately and correctly translate positions in a stream of real-time coordinates.

The Pozyx architecture comprises three main parts:

• A network of anchors and tags. This network consists of two types of devices: tags and anchors. The tag is a mobile device used to track the positions of an asset or person in real-time. An anchor is a signal capturing device on a fixed, well-known position.
• A local gateway. This device is the positioning server and connects to the Anchors via Ethernet. It gathers all the data received from the Anchors and transforms it into a position. By connecting to the gateway, users can receive real-time positioning data.
• The Pozyx web application. The web application is a visual interface to configure and manage the Pozyx system. It can be run locally from the gateway itself or from the Pozyx cloud.

General Technical Specifications

For extensive technical specifications, please consult the Pozyx Anchor Datasheet.

Installing the Anchor

8.1 Mounting Anchors
Mountain brackets allow users to install the Pozyx Anchors security to a wall or ceiling. Three types of mounting brackets are available to mount an Anchor:

• VESA pole mount (90-020-0001)
  

• VESA wall mount (90-020-0002)
  

• VESA ceiling mount (90-020-0003)

The Anchor is mounted with 4 M4 screws on the mounting bracket.
8.2 Connecting Cables
Pozyx Anchors can be connected through Ethernet. Each Anchor has 2 RJ45 100Base-T ports.
They can be used to link up anchors in a sequence which reduces the total amount of wiring required. We call this Daisy Chaining of Anchors.

• The port labeled “1” should be connected to the Positioning Gateway. This can be implemented either by a direct connection to one of the Anchor ports on the gateway or by a connection through an Ethernet switch for large setups.

• The port labeled “2” can be used to connect Anchors in a daisy chain.

To create a chain of Anchors connect the port “2” (OUT in the figure below) of an Anchor to the port “1” (IN in the figure below) of the next Anchor in the chain.
Pozyx recommends using Ethernet cables that:

• Are Pure Copper (Cu). Do not use Copper Clad Aluminum (CCA)
• Are Shielded Foil Twisted Pair (S/FTP)
• Are Cat5e (or better)
• Are AWG24 (or better). Both AWG 24/1 and AWF24/7 are suited.

Warning: It is advised not to use crossover Ethernet cables: all Ethernet cables should use the T568B wiring specified in the TIA/EIA-568 standard.
Warning: For system stability, it is advised to connect only anchors (and network switches solely used to aggregate Anchors) to the ports labeled “Anchor network” on the gateway.
8.3 Powering the Anchor
The Anchor is powered using Power-Over-Ethernet (PoE/PoE+). This option requires an Ethernet switch with PoE capability to be placed between the gateway and the first Anchor in a daisy chain. Each Anchor will provide power on the outgoing Ethernet cable for the next Anchors in the chain. The Ethernet cable that provides power to the Anchor must be connected to the port labeled “1”.

Remark: In general, 4-5 anchors (depending on the installation setup and environment and taking the conditions into consideration) are the maximum for a chain when powered through a PoE Switch, more will cause networking issues. Be sure to use shielded Ethernet cables to eliminate cross-talk.
Warning: It is not allowed to power an Anchor through the Ethernet Port 2.
Warning: Make sure that you use the correct ports to connect the incoming and outgoing Ethernet cables on the anchor.
8.4 Anchor Header
The header 90-010-0102 provides IP66 and IP67 ingress protection to the Anchor. The Ethernet cables enter the Header sideways.

8.4.1 Mounting the IP66/67 header

1. Place the RJ 45 connector on the Ethernet cable according to the T568B convention when using an Ethernet cable without pre-confectioned connectors.
   Warning: Make sure that the RJ45 connectors are suited for the deployed Ethernet cable.

2. Place the Tightening nut over the Ethernet cable.

3. Place the grommets over the Ethernet cable.

4. Pull the Ethernet cable thru the cable glands.

5. Plug the Ethernet connectors into the correct RJ45 jack. Route the Ethernet cables in a crossed way inside the cover as illustrated below.

6. Apply the provided lubricant on the O-rings of the IP66/67 header. Warning: Use only lubricants based on silicone or PTFE. 

7. Push the IP66/67 header onto the Anchor base module, until the clips snap on the base module.

8.  Push the grommets in the cable glands.

9. Screw the tightening nut onto the cable glands until fixed. The maximum torque is 6.0 Nm.

If the header needs to be unmounted, follow the above steps in reverse order.
Warning: To provide IP66/67 protection, the diameter of the Ethernet cables must be tailored to the grommets provided with the header. The standard cable diameter should be 5.4 mm ±10%. Contact Pozyx for other options.
Warning: Make sure that a blind grommet is placed in the right side cable gland if the Anchor is the last in an Anchor daisy chain.
8.5 Best Practices for Anchor Placement
For the most accurate positioning, the following general guidelines apply.

• The Anchors should have line – of – sight to each other.
• An Anchor should be placed each 10 m (1 anchor/100 m2). However, this can vary depending on the environment. On some occasions, it can be more or fewer, but we recommend a maximum anchor separation of 20 m.
• A tag should be surrounded by anchors in all directions. This can be achieved by
  placing an Anchor in each corner of the room in which tags are to be positioned.

8.5.1 specific guidelines for 2D positioning:

• Place the anchors high and in line of sight of the
  Placing the anchor high (on the ceiling or on the walls) increases the chance of receiving a good signal because there are fewer obstructions. Obstructions generally have a negative influence on the accuracy of the range measurements which has a direct effect on the positioning accuracy.

• Spread the anchors around the user. Don’t place them in a straight line. For range-based systems, single range measurement will only give information in a single direction. This direction is exactly the direction from the user to the anchor. Because of this, it is best to spread the anchors such that they cover all directions. If the anchors are all on a straight line, the positioning error will (can?) be very large: A small change in radius (for example due to noise), will result in a very large change in the position of the intersection(s).

• Make sure each anchor sees at least two, but preferably more neighboring anchors at a distance of not more than 20 to 30 meters, or even less in environments with many obstacles

• Place anchors vertically, with the connectors at the top. This keeps the antenna at the bottom

• Materials like metal, water, and wires should stay away from the anchors, especially the antenna: Within a few centimeters from the antenna, there should be no metal at all, not even small screws.

• It is recommended to have a separation of 20 cm between the anchor and walls. Extra mounting equipment can be used to achieve this.

8.5.2 Specific guidelines for 3D positioning:

• Keep to the guidelines from above but place anchors at different heights: The accuracy of the z coordinate will highly depend on the spread in heights of your Ideally, it is advised to place your anchors in the shape of a cube around your positioning zone as shown below. Try to maximize the distance between the lower and higher anchors.

• Twist the base surface of your cube 45 degrees as compared to the top surface:
  

• Keep the same max distance between the anchors as for 2D positioning (10 to 20 m depending on the environment)

• With only 6 anchors, it is possible that the resulting positions will be noisier. The  recommendation, in this case, is to place 3 anchors on the top surface and 3 on the bottom surface
