14.1
, 14-1 IEEE 802.11
IEEE has defined the specifications for a wireless
LAN, called IEEE 802.11, which covers the physical
and data link layers.
Topics discussed in this section:
Architecture
MAC Sublayer
Physical Layer
14.2
, Note
A BSS without an AP is called an ad hoc
network;
a BSS with an AP is called an
infrastructure network.
