As mentioned before, it’s very important that the anchors' clocks are accurately synchronised with each other. We achieve this by putting the anchors in one (or more) synchronisation zones. This is done automatically by the system based on the UWB connectivity between the anchors.

Go to the Anchor connectivity page: https://app.pozyx.io/setup/rollout/connectivity and press the Capture UWB connectivity button:

Now, in the list, it will be visible per anchor how many UWB reliable links they can make with their neighbors:

If at least 2 reliable links can be made, the anchors will be able to synchronize very accurately with each other. If some anchor does not have sufficient neighbors, a warning will be shown, and it is recommended to move the anchor such that it is in view of its neighbors.

Once all anchors have good connectivity, it is expected that they are no longer moved.
