Optimal Uncalibrated RSS Indoor Positioning and Optimal Reference Node Placement Using Cramér-Rao Lower Bound

Table 1

Typical uncertain parameters models when production calibration is run, or when calibration is done at the setup process in situ, or for the uncalibrated scenario. The notation is the value obtained from calibration where is the normal law of mean and variance .

Parameters	Production calibration	In situ calibration	Not calibrated
: AP gain mismatch
: asset gain mismatch		Non Applicable
: room path loss exponent	Nonrelevant
: reference gain
: noise measurement and shadow probability
