ADAPTIVE LOCATION TRACKING SYSTEM

摘要

This document presents a location tracking system comprising a plurality of location tracking nodes disposed to cover an area where the location tracking is to be carried out, at least one mobile tag configured to communicate with at least one of said plurality of location tracking nodes at a time for location tracking purposes, and a control apparatus configured to control operational parameters of the plurality of location tracking nodes and the at least one mobile tag. The control apparatus and the plurality of location tracking nodes are configured to carry out an automatic calibration phase during operation of the location tracking system the location tracking nodes transmit and receive test signals between the neighboring nodes, and report measurement results to the control apparatus. The control apparatus then optimizes the operation parameters of the location tracking system on the basis of received measurement reports.

1. A system for tracking location, comprising:
a plurality of location tracking nodes disposed to cover an area where the location tracking is to be carried out; at least one mobile tag configured to communicate with at least one of said plurality of location tracking nodes at a time for location tracking purposes; and a control apparatus configured to control operational parameters of the plurality of location tracking nodes and the at least one mobile tag, wherein the control apparatus and the plurality of location tracking nodes are configured to carry out an automatic calibration phase during operation of the location tracking system, wherein the calibration phase comprises: transmitting a test signal with designated transmission power from one location tracking node; receiving the test signal in another location tracking node and determining the location tracking node that transmitted the test signal from the test signal; transmitting to the control apparatus a measurement report comprising an identifier of at least one location tracking node from which the test signal was received; receiving a plurality of measurement reports from a plurality of location tracking nodes in the control apparatus; and reconfiguring, by the control apparatus, at least some parameters of at least one location tracking node and/or at least one mobile tag on the basis of the received measurement reports.
