In one aspect, a method is described. The method includes detecting a first data packet transmitted through a wide area network (WAN), the first packet representing media presented at a client device of a plurality of client devices at a media exposure measurement location, each client device having a respective device identifier; detecting, within a monitoring interval, one or more second data packets transmitted through a local area network (LAN), each of the one or more second packets specifying a candidate device identifier, where the monitoring interval comprises a time window from the detection of the first packet; generating a score for each candidate device identifier based on a number of the second packets detected within the monitoring interval; based on the score, selecting, from the candidate device identifiers, a target device identifier; and storing data correlating the first packet with the target device identifier.

Monitoring encrypted network traffic data

Methods, apparatus, systems and articles of manufacture are disclosed to determine virtual WiFi data rate. An example disclosed herein includes a control frame receiver to capture control frames from a user device. The example disclosed herein further includes a bitrate calculator to calculate a bitrate for each control frame by dividing a bitmap of a control frame by an amount of time between the control frame and a previously captured control frame. The example disclosed herein further includes an interval timer to control a length of time that the control frames are captured before calculating the virtual bandwidth. The example disclosed herein further includes a virtual bandwidth calculator to calculate the virtual bandwidth after the length of time, the virtual bandwidth calculated by dividing an average bitrate from the control frames by the length of time.
