Researchers at UC Santa Barbara propose a framework to sense occupancy attributes of an area, such as speed of a crowd traversing through the area, the total number of people in the area, and the rate of arrival of people into the area, using only the received power measurements (RSSI) of two WiFi links. They developed a mathematical model to relate these parameters to the occupancy attributes of interest. They tested the technology in different locations, with different wall properties and with several different numbers of people — up to and including 20. They showed a counting accuracy of 2 people or less 100 percent of the time with only one WiFi link… read more. Open Access TECHNICAL ARTICLE
