1. A system for adjusting the strengths of signals received from a transmitter based on the transmitter's likely location, comprising:
the transmitter associated with an individual;
one or more receivers configured to receive one or more signals transmitted by the transmitter, the one or more receivers being positioned at respective receiver locations corresponding to one or more respective areas;
one or more processors; and
a memory storing computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to:
receive location information indicative of one or more receiver locations corresponding to the one or more respective areas expected to be visited by the individual;
receive measurements indicative of signal strengths of one or more signals transmitted by the transmitter and received by the one or more receivers;
adjust the received measurements indicative of the signal strengths of the one or more signals transmitted by the transmitter based on the one or more respective areas expected to be visited by the individual,
wherein causing the one or more processors to adjust the received measurements indicative of the signal strengths of the one or more signals transmitted by the transmitter includes one of:
incrementally changing the received measurements by a first predetermined value based on the one or more respective areas expected to be visited by the individual, and
multiplying the received measurements by a second predetermined value based on the one or more respective areas expected to be visited by the individual.
