Header section- used to synchronize to the beginning of the packet. This consists of a row of 20 bit one’s followed by a single bit zero. The long sequence of one’s gives the receiver time to settle and the decoding software to synchronize. Address- consists of 8 bit data in the byte followed by a single bit one and single bit zero. Receiver checks these bytes to make sure its intended for this receiver. Data- this is same as address, 8 bits followed by a single bit one and a single bit zero. Checksum- consists of 8 bits followed by a single bit one and a single bit zero. This byte makes sure that data the data is received correctly. If it fails data should be discarding. Total of 52 bits to send just a 8 bits data byte. Two bytes will take 62 bits or four bytes will take 82 bits.
