Location determination method and location determination system for sensor apparatus placements in building
First Claim
1. A location determining method for sensor apparatus placements in a building comprising:
- transmitting, by a first portable test device, a first test signal through a specific channel at a first location which is a current location of the first portable test device in the building and a potential location of a first sensor in the building;
transmitting, by a second portable test device, a first echo back signal which transmits through the specific channel at a second location which a current location of the second portable test device in the building and is a potential location of a second sensor or an access point in the building if the first test signal is received;
measuring, by the first portable test device, a first channel quality of the specific channel based on the first echo back signal;
determining, by the first portable test device, a first candidate location of the first sensor based on the first location if the first channel quality is higher than a reference value;
storing, by the first portable test device, the first candidate location;
measuring, by the second portable test device, a second channel quality of the specific channel based on the first test signal or a second test signal from the first portable test device;
determining, by the second portable test device, a second candidate location of the second sensor or the access point based on the second location if the second channel quality is higher than the reference value; and
storing, by the second portable test device, the second candidate location,wherein the first location and the second location are inputted by a user or detected based on an indoor positioning technology.

Abstract
A location determining method 200 for sensor apparatus placements in building includes: a step in which a first measuring device transmits a digitally modulated first test packet through a specific channel at a first location in a building (210); a step in which a second measuring device receives the first test packet and transmits a first echo back signal through the specific channel at a second location in the building (220); a step in which the first measuring device receives the first echo back signal transmitted from the second measuring device and measures a first channel quality of the specific channel based on the first echo back signal (230); a step in which the first measuring device transmits a digitally modulated second test packet through the specific channel (240); a step in which the second measuring device receives the second test packet and transmits a second echo back signal through the specific channel (250); and a step in which the first measuring device receives the second echo back signal transmitted from the second measuring device and measures a second channel quality of the specific channel based on the second echo back signal (260).

7. A location determining system for sensor apparatus placements in a building comprising:
-
a first portable test device which is located at a first location which is a potential position of a first sensor in the building and configured to transmit a modulated first test signal through a specific channel, receive a first echo back signal from a second portable test device, measure a first channel quality of the specific channel based on the first echo back signal, determine a first candidate location of the first sensor based on the first location if the first channel quality of the specific channel is higher than a reference value, and store the first candidate location; and the second portable test device which is located at a second location which is a potential position of a second sensor or an access point in the building and configured to transmit the first echo back signal through the specific channel if the first test signal is received, measure a second channel quality of the specific channel based on the first test signal or a second test signal from the first portable test device, determine a second candidate location of the second sensor or the access point based on the second location if the second channel quality of the specific channel is higher than the reference value, and store the second candidate location, wherein the first location and the second location are inputted by a user or detected based on an indoor positioning technology. - View Dependent Claims (8, 9, 10, 11, 12)
