Methods, apparatus, and articles of manufacture to locate persons based on adjustable signal strength thresholds

An audience measurement computing system comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the audience measurement computing system to perform operations of assessing location within a media presentation environment, the operations comprising:
• receiving, by a wireless device and from a remote server, a signal strength threshold to set for one or more radio frequency (RF) beacons deployed within the media presentation environment;
• storing, by the wireless device, the signal strength threshold in a memory of the wireless device;
• receiving, by the wireless device and from the one or more RF beacons, a beacon detection signal;
• determining, by the wireless device, that the beacon detection signal satisfies the signal strength threshold;
• and
• based on determining that the beacon detection signal satisfies the threshold, processing the beacon detection signal to determine a location of the wireless device with respect to the one or more RF beacons in the media presentation environment.
