Abstract
A method and apparatus to enable physical layer MAC layer enhancements while at the same time allowing complete backward compatibility with existing protocols. The method and apparatus determine on a packet by packet basis if a transmission originated from a standard or enhanced node by correlating each packet with a known sequence during the synchronization preamble, before any header or data arrive.
