Revision History

Overview

The Enterprise Anchor captures, preprocesses, and sends location data from tags to the Positioning Server. 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 Positioning Server to accurately and correctly translate tag positions in a stream of real-time coordinates.

Figure 1 Pozyx Enterprise System Architecture

The Pozyx RTLS 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 Positioning Server. This device 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 Positioning Server, users can receive the real-time positioning data.
• The Pozyx web application. The web application is a visual interface to configure and manage the Pozyx RTLS system. It can be run locally from the Positioning Server itself or from the Pozyx cloud.

Installing the Anchor

Mounting Anchors

Mounting brackets allow users to install the Enterprise Anchor V2.1 to a pole, wall or ceiling. Three types of mounting brackets are available to mount an Enterprise Anchor V2.1:

• 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.

Connecting Cables

Enterprise Anchors can be connected through Ethernet. Each Enterprise Anchor has 2 RJ45 100Base-T ports. They can be used to link up anchors in sequence which reduces the total amount of wiring required. We call this Daisy Chaining of Anchors.

Figure 2 Pozyx Anchor PoE ports

• The port labeled “1”should be connected to the Positioning Server. This can implemented either by a direct connection to one of the Anchor ports on the Positioning Server 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:

1. Are Pure Copper (Cu). Do not use Copper Clad Aluminum (CCA)
2. Are Shielded Foil Twisted Pair (S/FTP)
3. Are Cat5e (or better)
4. 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 Positioning Server.

Powering the Anchor

There are two options to power an Enterprise Anchor:

• Using Power-Over-Ethernet (PoE/PoE+). This option requires that an Ethernet switch with PoE capability is placed between the Positioning Server and the first anchor in a daisy-chain. Each anchor will provide power on the outgoing Ethernet cable for the next anchor 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 cabling and taking the environmental conditions into consideration) is the maximum for a chain when powered through a PoE+ Switch, more could cause networking issues. Be sure to use shielded Ethernet cables to eliminate cross talk.

• Local power DC jack: This option uses an external AC/DC convertor to power the first anchor in a daisy-chain.
  

Warning: It is not allowed to power an Enterprise 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 Enterprise Anchor.

Anchor Headers

Two types of headers are available for the Enterprise Anchor:

• The header 90-010-0101 provides IP66 and IP67 ingress protection to the Enterprise Anchor. The Ethernet cables enter the header sideways.
  

• The header 90-011-0001 can optionally be used to guide the external cables. The ingress protection level of this solution is IP20. The header allows users to route the cabling upwards from or to the backside of the Enterprise Anchor.

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 header as illustrated below.
   
   Figure 3 Anchor Ethernet cable connection

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 Enterprise 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 7 mm ±10%. Contact Pozyx for other options.

Warning: Make sure that the blind grommet, that is provided with the IP66/67 header, is placed in the right side cable gland if the anchor is the last in an anchor daisy chain.

Mounting the IP20 header

To mount the IP20 header follow the steps below:

1. Place the RJ45 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. Pull the Ethernet cables and the DC power cable (if used) through the appropriate holes in the header. Make sure that the cables will not cross after mounting the header on the Enterprise Anchor base module.

3. Plug the Ethernet connectors into the correct RJ45 jack. When used, also plug the DC plug into the DC Jack of the Enterprise Anchor

4. Push the header onto the Enterprise Anchor base module.

5. Push the cable into the top or rear exit holes in the header.

6. Readjust the header if it moved during Step 5.

Best Practices for Anchor Placement

For the most accurate positioning the following generic 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. In some occasions it can be more or  fewer, but were commend 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.

Specific guidelines for 2D positioning:

• Place the anchors high and in line-of-sight of the user.
  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 on a straight line.

• For range-based systems, single range measurements 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 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). In other words, the error on the range measurements is amplified! This is the same principle as in GPS, where it is called the geometric dilution of precision (GDOP).

• Make sure each anchor sees at least two, but preferably more neighboring anchors at a distance of not more than 15 to 20 meters, or even less in environments with many obstacles. It’s very important that the clocks of the anchor are accurately synchronised with each other, and this happens through UWB. It’s therefor important that not only the tags have line-of-sight to the anchors, but also that the anchors have a line-of-sight with each other.

• 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. Our mounting equipment can be used to achieve this.

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 anchors. 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:
  
  Twisting the base surface will reduce the 3D convex hull of the anchors (e.g. the bottom corners of the cube are outside of the convex hull), but it will generally give you a higher chance of line-of-sight between a tag and the anchors. E.g. when your body is blocking 1 corner of the room it will just block line-of-sight with 1 anchor instead of 2. Furthermore its better for the tag to be surrounded by anchors from as much directions as possible.

• Place the bottom anchors upside down as this will point the antenna upwards (= towards the tags).
