# How to think about placing UWB beacons?

I’m planning to get some UWB beacons for a trial. We had previously planned to use location beacons (BT) and we used an overlapping isovist strategy to place them. The diagram below show the number of beacons (red circles) that each square can see.

Most squares can see 3 or more beacons.

We’re planning to trial the UWB beacons in the same section of the office. What’s the strategy for locating the wall mounted/ fixed beacons?

In some kind of pure geometrical sense, as long as a few moving beacons can see 3 fixed, they should be able to mesh locate all the others. I’d imagine that this is a bit of a pipe dream and that we’ll need more than that.

The guideline says one every 5 metres on the walls, but that seems like a lot near the edges, and too few in open areas.

This question has been mentioned before, but not answered: Location with UWB Beacons spacing guidelines

To restate the question in a more specific way: How many fixed beacons would you expect to need in the coloured area?

The guideline says one every 5 metres on the walls, but that seems like a lot near the edges, and too few in open areas.

A more accurate description would be a 5 m × 5 m grid, which for your floor plan would mean 2-3 beacons × 3 beacons = 6-9 beacons.
