Methods and apparatus for multimodal audience detection and identification

A method comprising:

• selecting a portion of a set of signal strength values associated with advertising packets from a device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations;
• calculating a first representative signal strength value based on the selected portion of signal strength values;
• and
• determining a presence of the user based on whether the first representative signal strength value satisfies a threshold.

A non-transitory computer readable medium including instructions which, when executed, cause a processor to at least:

• select a portion of a set of signal strength values associated with advertising packets from a device associated with a user, the advertising packets captured by a multi-axis receiver on a plurality of different signal polarizations;
• calculate a first representative signal strength value based on the selected portion of signal strength values;
• and
• determine a presence of the user based on whether the first representative signal strength value satisfies a threshold.
