The range of a beacon-triggered message can vary depending on a number of factors, including the strength of the signal, the environment in which the beacon is operating, and any obstructions or interference that may be present. Standard beacons have an approximate range of 70 meters.
However, it's important to note that the effective range of a beacon can be significantly reduced by physical obstructions such as walls, trees, or other obstacles that can block or weaken the signal. (e.g. in a leather handbag or with a thick case).
