ipfProximity {ipft}

Estimates the position of the observations from its fingerprints and the access point location usins a logarithmic path loss model

Description

Estimates the position of the observations from its fingerprints and the access point location usins a logarithmic path loss model

Usage

ipfProximity(bpos, rssirange = c(-100, 0), norssi = NA, alpha = 5,
  wapPow1 = -30)

Arguments

bpos

a matrix or a data frame containing the position of the beacons, in the same order as they appear in fingerprints

rssirange

range of the RSSI data

norssi

value used to represent a not detected AP

alpha

path loss exponent

wapPow1

detected RSSI at one meter range

Value

An S3 object of class ipfEstimation, with the following properties: location -> a matrix with the predicted locations errors -> a numeric vector with the errors, if loctest has been provided neighbors -> NULL weights -> NULL

Examples

    ipfEst <- ipfProximity(ipftrain[1:10, 1:168], ipfpwap, ipftrain[1:10, 169:170], alpha = 4)
