Apparatus, system, and method of communicating an extended range (ER) physical layer (PHY) protocol data unit (PPDU)
For example, a wireless communication device may be configured to generate, transmit, receive and/or process one or more transmissions of an Extra Range (ER) Physical layer (PHY) Protocol Data Unit (PPDU), which may be configured to be decodable by ER wireless communication stations (STAs). For example, the ER PPDU may include an ER preamble. For example, the ER preamble may be configured to include an ER STF (ER-STF), an ER LTF (ER-LTF) after the ER-STF, and an ER Signal (ER-SIG) field after the ER-LTF. In one example, the ER PPDU may include a non-ER preamble, which may be configured to be decodable by non-ER STAs, which may not be capable of decoding the ER preamble.
