what i know about Preamble
it is a technique to make synchronous between Tx & Rx
it sends a certain byte to make order to Rx to begin to rreceive and process data
for example on data network; computer send this byte '10101011'
so receiving computer when receive 0101... it make attention to be ready
until it receives ' 11' then it begins to process the next bytes
