Abstract

A method and system comprises receiving a signal over an air interface. A binary sequence is detected in the signal. A legacy signal (L-SIG) field of a physical layer protocol data circuit (PPDU) is decoded based on the detected binary sequence and based on decoding the L-SIG field, two spoofing symbols which directly follow the L-SIG field is checked in the PPDU, wherein the two spoofing symbols comprise binary phase shift keying (BPSK) symbols. Based a presence of the two spoofing symbols, a long range portion of the PPDU is processed; and based on an absence of the two spoofing symbols, the PPDU is processed as a legacy PPDU.
