Abstract
Here we calculate the dwell time at different locations for the wireless client device when it was stationary and also do path tracing to track the movement of client device from previous locations to current location. For segments of the path where the client was not stationary we can use Point Smoothening techniques like Moving Average to filter the noise in the location computed using different algorithms like trilateration from the RSSI values for the client device from different Wireless Access Points. Now with the help of path tracing of the client device and maintaining the dwell time of the client device at each point in the path, we calculate the average dwell time for all points in the area or site per client device which helps us to generate Heat Map for the area or the site.
Description
Device Path Tracking for generating Heat Maps
In this invention we have a wireless network deployment at a site consisting of different areas. For each wireless client device in the network we compute its exact location in the area or site and periodically (typically 3 to 10 seconds) keep tracking the location where the client device is. It is possible that the client device is stationary or it moves to a different location. We calculate the dwell time at different locations for the client device when it was stationary and also do path tracing to track the movement of client device from previous locations to current location. For segments of the path where the client was not stationary we can use Point Smoothening techniques like Moving Average (which is a calculation to analyse data points by creating series of averages of different subsets of the full data set) to filter the noise in the location computed using different algorithms like trilateration from the Received Signal Strength
Indicator (RSSI) values for the client device from different Wireless Access Points. Now with the help of path tracing of the client device and maintaining the dwell time of the client device at each point in the path, we calculate the average dwell time for all points in the area or site per client device. Depending upon the range in which the average dwell time value per client device lies for a given point in the area, we use different colour codes for different ranges to mark those points in the area or site and generate what we call is the Heat Map for the area or the site.
Claims
1. In this invention we have a wireless network deployment at a site
consisting of different areas. For each wireless client device in the network we compute its exact location in the area or site and periodically (typically 3 to 10 seconds) keep tracking the location where the client device is. It is possible that the client device is stationary or it moves to a different location. We calculate the dwell time at different locations for the client device when it was stationary and also do path tracing to track the movement of client device from previous locations to current location. For segments of the path where the client was not stationary we can use Point Smoothening techniques like Moving Average (which is a calculation to analyse data points by creating series of averages of different subsets of the full data set) to filter the noise in the location computed using different algorithms like trilateration from the Received Signal Strength Indicator (RSSI) values for the client device from different Wireless Access Points. Now with the help of path tracing of the client device and maintaining the dwell time of the client device at each point in the path, we calculate the average dwell time for all points in the area or site per client device. Depending upon the range in which the average dwell time value per client device lies for a given point in the area, we use different colour codes for different ranges to mark those points in the area or site and generate what we call is the Heat Map for the area or the site. The above novel technique of generating Heat Maps for different areas in a site using Path Tracing mechanism for a client device is the claim for this invention.
