    You're right. Sorry for not checking the actual links and thanks for
    finding the articles on the Archive.<br>
    <br>
    The material is the blogs is in the CWNA 5th Edition Study Guide.
    Note, however, that the OFDMA DL explanations don't really explain
    what products (at least those that have enabled OFDMA) are doing.<br>
