APPARATUS AND METHOD FOR ASSESSING A RELATIVE DISTANCE OF PERSONS AND OBJECTS

摘要

The present invention discloses a method to determine the relative distance between electronic devices, by having a main electronic device communicating with at least two electronic devices in a wireless manner, the method comprising changing in a controlled manner a communication parameter used in the wireless communication between the main device and the said electronic devices, conducting wireless communication between said main device to each of the said other devices after each change of parameter, logging if receiving wireless signals from each one of the said two electronic devices for each said change of the communication parameter in said changed state, determining at the main electronic device that one of the at least two electronic devices is closer or further-away than the other electronic device of the at least two electronic devices in relation to the main device.
