# This option allows to create a new AP when a request is captured by an

# by an unknown AP.
# It is unactivated by default for the sake of security.

# Since MinMax is currently the only trilateration method implemented
# in OwlPS, you should define these parameters if you use any of the
# trilateration-based algorithms (InterlinkNetworks, FBCM, FRBHM).

# Algorithm to calculate the similarity, in the signal strength space,
# of two measurements.
# The following algorithms are implemented:
#   - mean: The mean of all the packets in the measurement is
#     computed, then the euclidean distance between the two means is
#     used.
#   - interval: The mean Im and the standard deviation Is of the
#     packets in the measurement I are computed; the closest reference
#     measurement R is the one with the highest number of packets in
#     the interval [Im-Is, Im+Is].
#   - interval2: Derived of the previous one, this algorithm
#     computes the percent of packets in both the intervals
#     [Im-0.674×Is, Im+0.674×Is] and [Im-Is, Im+Is].
#     Assuming a normal distribution, we should find approximately
#     50% of the packets in the first interval, and 68% in the second
#     interval. The closest R is the one for which the percents of
#     the two intervals are the closest to these theoretical scores.
# The default is "mean".

# Smallest possible value for a received signal strength, in dBm. This

# received.

# If disabled, the generated reference points will contain a series of
# packets, better matching the real requests.

# This option allows the calibration requests sent during the
# positioning phase to be added to the calibration request's list. They
# are added to the calibration requests read by InputDataReader during
# the start-up phase. If this option is not activated, the calibration
