Beacon Throttle
The beacon continuously monitors and adjusts its output power in order to maintain a constant signal
strength. Beacon housing properties, battery chemistry and battery voltage impact the beacon’s ability to
maintain this output. Beacon throttle is a measure of the remaining time a beacon will be able to maintain
its output level.
