Abstract
In one exemplary embodiment, a process for detecting a phone includes monitoring wirelessly transmitted traffic between first and second stations. Next, the process determines whether the traffic sent in both directions between the first and second stations are close to each other in term of traffic volume. The process identifies a total frames count of a number of frames of an identical frame size transmitted, where the number of frames is greater than any number of frames of a same size. The process calculates the percentage of the count that was just collected out of the count of the total frames. The process identifies the first station as a phone if the calculated percentage is over a first threshold and the total frames count is over a second threshold.
