Long range WLAN data unit format
First Claim
1. A method for generating a data unit for transmission in a wireless network, the method comprising:
- generating a physical layer (PHY) preamble, including;
generating a first indicator to indicate at least one of (i) whether the data unit includes data offloaded from a mobile telephony network separate from the wireless network, or (ii) whether the data unit (a) was generated by, or (b) is addressed to, a communication device that supports offloading of data from the mobile telephony network to the wireless network,including the first indicator in the PHY preamble;
generating a media access control layer (MAC) header;
generating the data unit to include the PHY preamble and the MAC header; and
causing the data unit to be transmitted.

Abstract
In a method for generating a data unit for transmission in a wireless network, a physical layer (PHY) preamble is generated. In generating the PHY preamble, a first indicator is generated to indicate at least one of (i) whether the data unit includes data offloaded from a mobile telephony network separate from the wireless network, or (ii) whether the data unit (a) was generated by, or (b) is addressed to, a communication device that supports offloading of data from the mobile telephony network to the wireless network. The first indicator is included in the PHY preamble. Additionally, a media access control layer (MAC) header is generated. The data unit is generated to include the PHY preamble and the MAC header. The data unit is then caused to be transmitted.
