A hidden node occurs when two stations are within range of the same access point, but are not within range

of each other. The following figure illustrates a hidden node. Both stations (STA) are within range of the

access point (AP) or wireless gateway, but out-of-range of each other, so they cannot “hear” each other, that

is they do not know if the channel is currently being used. Therefore, they are considered hidden from each

other.
