    Yes, 802.11 implies 802. You can get a nice overview of ieee802 and
    its subclasses and media-types here:

     http://standards.ieee.org/getieee802/portfolio.html
     http://standards.ieee.org/getieee802/download/802-2001.pdf

    You've got the ieee802 base framework, the ieee802.1 bridging and
    management, the ieee802.2 logical link control and the various MAC
    and PHY types in 802.3 to 802.16 (with the exception of 802.10 which
    is an encryption layer for all 802 media).

    The most known and important of the 802.1 generic classes are 802.1d
    for bridging, 802.1q for virtual LAN's and 802.1X for port based access
    control. Those apply to all 802 subclasses be it Ethernet (802.3)
    or Wireless LAN (802.11).
