Preamble:
A preamble is a signal used in network communications to synchronize the transmission timing between two or more systems. Proper timing ensures that all systems are interpreting the start of the information transfer correctly. Part of the frame that is transmitted by an 802.11 station is called the preamble. The original 802.11 specification (which defined only 1 and 2Mbps operation), defined only a long preamble that uses a 128 bit sync field. When the high rate, i.e. 11Mbps, 802.11b standard was created, an optional short preamble using a 56 bit sync field was added. This was intended to improve the efficiency of the wireless network for more
