1. A system, comprising:
- a first access point comprising an adjustable power amplifier and an antenna;
a memory comprising encoding and transmitting logic; and
a processor, the processor configured by the encoding and transmitting logic to;
cause the first access point to provide a primary beacon at a first power level; and
cause the first access point to provide a secondary beacon at a second power level, the second power level less than the first power level;
receive a response signal from a receiving device responsive to the secondary beacon; and
determine that the receiving device is within an intended coverage area responsive to receiving the response signal.
