A device comprising at least one hardware processor obtains a bandwidth for a communication from a station in a wireless network and a signal strength for the communication from the station, and determines that the communication is a communication related to network maintenance in case the bandwidth is below a first value and an expected bandwidth based on the signal strength is above a second value, and that the communication is a data communication in case the bandwidth is below the first value and the signal strength is below the second value, in case the communication is a data communication, the at least one hardware processor can determine that the station is active.
