A rogue base station is an attacker station that duplicates a legitimate base station. The rogue base station puzzles a set of subscribers trying to get service through what they believe to be a legitimate base station. It may result in long disturbance of service. The exact method of attack depends on the type of network. In a WiFi network, which is carrier sense multiple access, the attacker has to capture the identity of a legitimate access point. Then it builds frames using the legitimate access point's identity. It then injects the crafted messages when the medium is available. In a WiMax network, this is more difficult to do because WiMax uses time division multiple access. The attacker must transmit while the rogue base station is transmitting.
