Abstract
A method of predicting positioning performance of a set of N access points in an indoor region includes: obtaining a signal-strength map including signal-strength vectors and corresponding locations in the indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of the set of N access points; and determining a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.

A method of predicting positioning performance of a set of N access points in an indoor region, the method comprising:
- obtaining a signal-strength map including signal-strength vectors and corresponding locations in the indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of the set of N access points;
- and
- determining a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.
An apparatus comprising:
- a processor configured to obtain a signal-strength map including signal-strength vectors and corresponding locations in an indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of a set of N access points;
- and
- an uncertainty module communicatively coupled to the processor and configured to determine a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.
An apparatus comprising:
- obtaining means for obtaining a signal-strength map including signal-strength vectors and corresponding locations in an indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of a set of N access points;
- and
- uncertainty means, communicatively coupled to the obtaining means, for determining a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.
A processor-readable storage medium comprising processor-readable instructions configured to cause a processor to:
- obtain a signal-strength map including signal-strength vectors and corresponding locations in an indoor region, the signal-strength vectors each including N signal-strength indications that each indicate an expected received signal strength from a corresponding one of a set of N access points;
- and
- determine a position uncertainty value using the signal-strength map, the position uncertainty value being indicative of a positioning accuracy at a corresponding point of interest in the indoor region.
