The correct deployment of anchors is crucial for optimum system performance. Please follow this section closely to ensure best positioning performance possible. Below are listed several points that should always be kept during the deployment process.
Always keep a clear line of sight between the master anchor and neighbor anchors within location cell.
The master anchor should always have a clear line of sight to at least three other anchors in its vicinity. It is not required to ensure line of sight between all anchors in the system just in the same location cell. Each location cell should have its own master. Master selection is done via RTLS Manager.
Deploy the anchors above the objects that are being located.
The anchors use a wireless synchronization, this means that they need a clear line of sight between each other. Therefore, it is best to mount them above any moving objects including the objects that are being localized.
Mount the anchors ideally at the same height in each location cell.
The best approach is to mount the anchors at the same height within the location cell. If given venue does not allows it try to keep them at least roughly within the same level, max. 100 cm difference. The absolute height should not exceed 6 meters above Tags, applies for Anchor 1.4.
Keep anchors separated from walls or ceiling.
Always mount the anchors on holders provided with them. Never place the anchors right on the wall or ceiling as it may affect the anchor’s antenna radiation pattern and decrease its radio performance.
Keep a square geometry during the deployment.
Due to dilution of precision phenomena, the best approach is the "squaring" the location cell. The ratio between the two sides should not be higher than 3:1 to achieve highest possible accuracy.
Try to maintain a direct line of sight between the tag and the anchors.
- Find a spot with minimum body mass for Tag placement on a person
- Find the highest point with minimum metal shielding for asset deployment.
Anchor 1.4 - always orient the anchors best radiation to the center of the room or the location area.
The anchor’s radiation should be oriented to the spots where tags will be located to ensure maximum signal coverage. The antenna has a different ideal radiation depending on the anchor type, see the figures below. The rule of thumb is that the Anchor 1.4 has the best antenna radiation on the side where the LED is located. Anchor Vista OmniLight is not sensitive to its orientation, it has equal truly 360 omni performance.
