This work aims to define a model for the relation between the Received Signal Strength Indicator (RSSI) of an Wireless Sensors Network (WSN) and the occupation rate of an indoor ambient.Experimental tests were carried out to identify this model that is able to provide the number of people (occupancy rate) in this ambient as a function of the RSSI variance.The tests were based on the installation of an WSN in a classroom, allowing to collect data related to RSSI variation, considering a point-to-point network.As a conclusion, it was possible to identify a relationship between these variables that determines the ambient occupancy rate.
