    66If you have questions about the 802.11 Reference Design that aren't address below or elsewhere in this user guide, please post to the [/forums forums] and we'll answer as quickly as possible.
    77
    8 == What parts of the 802.11 standard are implemented? ==
    9 Our implementation focuses on the OFDM PHY and DCF MAC. We tried to choose a subset of these specifications which are feasible to implement and provide the most utility to wireless networking researchers. We plan to continue developing the design in the coming months. Feedback is welcome on which features in the standard would be most useful in future releases.
     8== What is this design good for? ==
     9We hope this design will be a valuable starting point for wireless researchers looking to extend the 802.11 MAC and PHY and evaluate their extensions experimentally.

    11 The IEEE 802.11 standard is huge ([http://standards.ieee.org/getieee802/download/802.11-2012.pdf 2700 page PDF]). Implementing the entire standard on WARP is infeasible, and frankly not all that useful as a research tool.

    13 The specifics of the current implementation are discussed in the [wiki:../PHY PHY] and [wiki:../MAC MAC] pages of this user guide.
    1411
    1512== What hardware is supported? ==
    … …  
    1815Previous generations of WARP hardware are not supported, as the design requires tools and FPGA features which preclude porting to Virtex-II Pro or Virtex-4 FPGAs.

     17== What parts of the 802.11 standard are implemented? ==
     18Our implementation focuses on the SISO OFDM PHY and DCF MAC specified in IEEE 802.11-2012. We tried to choose a subset of these specifications which are feasible to implement and provide the most utility to wireless networking researchers. The current design will inter-operate with commercial 802.11g-compatible equipment in real-time.

    2024== How is the WARP 802.11 Reference Design licensed? ==
    2125
    22 The source code and models for the 802.11 Reference Design are distributed under the terms of the [wiki:../License Mango Reference Design License]. For any questions about the license terms please contact [http://mangocomm.com/contact Mango Communications].
     26The source code and models for the 802.11 Reference Design are distributed under the terms of the [wiki:../License Mango Reference Design License].
    2327
    2428It is our intention that users should be free to do the following with the 802.11 Reference Design
    25  * Use the Reference Design on Mango hardware for teaching and academic research
    26  * Modify the Reference MAC and PHY source code
     29 * Use the Reference Design on Mango hardware for teaching and research
     30 * Modify the Reference Design MAC and PHY source code
    2731 * Publish results from experiments using the Reference Design
    2832 * Share customized versions of our MAC and PHY with other users of the Reference Design
    2933
    30 Please note that the license requires this design only be used on hardware manufactured by Mango Communications. We recognize this requirement diverges from true open source. It is the only approach we can conceive that justifies the significant investment of resources to develop and support a complex design distributed at no cost. We want to provide hardware and reference designs that enable great research. We can't do this as free IP suppliers for competing platforms.

    33 == What encryption schemes are supported? ==
    34 None.
    35 
    36 This could be an interesting future extension, but is way outside our areas of expertise. As best we can figure, it also isn't necessary for most MAC/PHY experiments.
