Abstract
A method is implemented by a sensor device to associate data collected by the sensor device with an accurate time according to a world time standard without having to include a dedicated timing device within the sensor device, thereby reducing the cost and complexity of the sensor device. The method includes initiating a cellular receiver in the sensor device using a programmed carrier frequency, receiving at least one radio frame from a cellular transmitter on the carrier frequency; tagging data collected by the sensor device with a network tag derived from a most recent radio frame of the at least one radio frame in real-time, the network tag including a set of data from the most recent radio frame that is unique to the most recent radio frame.
