802.11 back off implementation RRS feed

  • Question

  • Hello, 

    We study the Sora's 802.11 implementation recently. 

    We could not find the code deal with the random back off in MAC. 
    Here is the question: which file contains implementation of back off mechanism?

    Thanks

  • You can refer the function MAC11a_Receive() in SoraSDK2.0\src\umxsdrbrick\mac.cpp.

    Please note that the the back-off implementation is not exactly matching 802.11 standard, because it does not monitor the channel during sending a packet. If it find a missing ACK packet, it will think conflict happens.
