Beacons vary in their range. The smaller battery beacons tend to have smaller 30m to 50m ranges to make the most of battery life. Larger battery beacons tend to have ranges up to 100m. Then there’s longer range beacons with ranges over 150m.
One thing to understand is what can block signals. In our experience, when a signal gets blocked, there’s no point trying beacons with longer ranges in the hope they will push the signal through the physical obstructions. Longer range beacons only work long range when there is unobstructed line of sight.
