These books attempt to give a description of the
various subsystems that play a role in 802.11 wireless
networking in Linux. Since these books are for kernel
developers they attempts to document the structures
and functions used in the kernel as well as giving a
higher-level overview.
</p><p>
The reader is expected to be familiar with the 802.11
standard as published by the IEEE in 802.11-2007 (or
possibly later versions). References to this standard
will be given as "802.11-2007 8.1.5".
