Hidden node problem
（重定向自Hidden node）
![Station A can communicate with Station B. Station C can also communicate with Station B. However, Stations A and C cannot communicate with each other since they cannot sense each other on the network, because they are out of range of each other.](/Images/godic/202501/18/Wifi_hidden_station_problem.svg5903.png")

In wireless networking, the hidden node problem or hidden terminal problem occurs when a node is visible from a wireless access point (AP), but not from other nodes communicating with that AP. This leads to difficulties in media access control sublayer.
