Content optimization of a physical layer preamble |
摘要 |
Embodiments of the present invention provide for content optimization of a physical layer preamble. In one embodiment of the invention, a method for encapsulating a payload for transmission through a network is disclosed. The method comprises the step of programming a legacy physical layer length value in a legacy physical layer preamble. The legacy physical layer preamble is configured such that it can be received by any legacy stations that may be on the network, and such that a separate physical layer length value can be derived from the legacy physical layer preamble. Using such a system, content optimization of a physical layer preamble is provided. |

1. A method for encapsulating a payload for transmission through a network comprising:
programming a legacy physical layer length value in a legacy physical layer preamble, wherein said legacy physical layer length value is expressed in units of bytes, wherein said legacy physical layer preamble is configured to be properly received by a set of stations on a network, even if a legacy station is in said set of stations; reappropriating a separate physical layer length field in a separate physical layer preamble to carry an alternative quantum of information, wherein the separate physical layer length field is originally appropriated to include a separate physical layer length value that is derived by dividing the legacy physical layer length value by a legacy number of bytes per symbol and subtracting a number of symbols in the separate physical layer preamble; forming a packet for transmission on the network, wherein the packet includes the payload, the legacy physical layer preamble and the separate physical layer preamble; and transmitting the packet to the network. |
