Understanding
802.11b
IEEE 802.11b is a wireless networking standard created by the Institute of
Electrical and Electronics Engineers (IEEE).
Add-Hoc Mode
Ad-Hoc mode allows wireless devices to communicate directly with each other,
eliminating the need for an access point or any connection to a wired network.
Ad-Hoc mode is also called peer-to-peer mode or independent Basic Service
Set (IBSS). See INFRASTRUCTURE MODE.
BSS
When an access point is connected to a wired network and a set of wireless
devices, it is referred to as a Basic Service Set (BSS). An Extended Service Set
(ESS) is a set of two or more BSS that form a single sub network. See ESS ID.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a procedure that computers on
a network follow to identify each other and make sure that information is
transferred correctly.
ESS ID
The ESS ID (Extended Service Set ID) is an identification assigned to the
access point the Wireless LAN Card connects to. Wireless devices connecting
to an access point must use the same ESS ID. The ESS ID can be up to 32
characters and is case sensitive. See BSS ID.
Infrastructure Mode
In infrastructure mode, the wireless network consists of at least one access
point connected to the wired network infrastructure and a set of wireless end
stations. See Ad-Hoc mode.
