Abstract
A method and system for detecting a hidden node in a wireless local area network having a first station, a second station, and an access point. The first station can send a message, where the message can be sent as a data frame. After receiving the message, the access point can send the message to the second station. The second station can receive the message from the access point. In response to receiving the message, the second station can send an acknowledgement to the access point, where the acknowledgement can be sent as a control frame. The first station can monitor for the acknowledgement sent from the second station to the access point.
