802.11n preamble is a type of preamble used in IEEE 802.11 wireless networks. It is used to synchronize a network node and an access point before data is transferred. It consists of a series of short pulses and is used to alert a device that a frame is about to start. The 802.11n preamble is designed to be more robust than earlier preambles, allowing for better reception and less packet loss in environments that have a higher level of interference.
