Method and apparatus for limiting redundant positioning polling from a mobile device in a real-time location system (rtls)

A non-transient computer readable medium for storing computer instructions that, when executed by at least one processor cause the at least one processor to perform a method of limiting redundant positioning polling from a mobile device in a Real-Time Location System (RTLS) comprising:

• reading a current position of the mobile device;
• establishing a virtual perimeter around the mobile device;
• measuring a plurality of signal strengths from a plurality of access points within the virtual perimeter;
• determining whether the mobile device has moved outside of the virtual perimeter;
• and
• transmitting a plurality of signal strengths from a plurality of access points to a location server when the mobile device has moved outside of the virtual perimeter.
