Systems and methods for signal classification

Abstract

This disclosure describes systems, and methods related to signal classification in a wireless communication network. A first computing device comprising one or more processors and one or more transceiver component may receive a signal transmission packet comprising a physical layer (PHY) preamble. The first computing device may identify within the PHY preamble, one or more signal (SIG) fields, wherein at least one of the one or more SIG fields includes at least a length field indicating a length of the signal transmission packet. The first computing device may determine based at least in part on the length field, that the signal transmission packet is associated with a predetermined communication standard utilized to transmit the signal transmission packet. The first computing device may decode the signal transmission packet based at least in part on the determination that the signal transmission packet is associated with the predetermined communication standard.
