Systems and methods for power management in a beacon

A method for power management in a beacon, comprising:

• determining a program density of a signaling program;
• determining an initial driving voltage using the program density;
• determining a current setting for an emitter using the initial driving voltage, the current setting enabling the emitter to repeatedly execute the signaling program for a predetermined amount of time while being powered by a power source;
• adjusting the initial driving voltage to a start-up voltage based on a first comparison comparing a start-up current through the emitter with the current setting and a second comparison comparing a start-up power source voltage with a minimum power source voltage;
• executing the signaling program using the start-up voltage;
• and
• adjusting the start-up voltage to a signaling voltage based on a third comparison comparing an execution current through the emitter with the current setting and a fourth comparison comparing an execution power source voltage with the minimum power source voltage.
