What is Wireless LAN?
A wirele
ss LAN (WLAN) is a network that
allows access to Internet without the need for any wired connections to the
user’s machine.
What are ISM bands?
ISM stands fo
r Industrial, Scientific and Medical; radi
o frequency bands that the Federal Communications Commission
(FCC) authorized for wireless LANs. The ISM bands are located at 915 +/- 13 MHz, 2450 +/- 50 MHz and 5800 +/- 75

How does wireless networking work?
The 80
2.11 standard define
two modes: infrastructure mode and ad hoc 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. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or
more BSSs forming a single subnetwork. Since most corporate WLANs require access to the wired LAN for services
(file servers, printers, Internet links) they will operate in infrastructure mode.
Example 1: wireless Infrastructure Mode
Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) is simply a set of 802.11
wireless stations that communicate directly with one another without using an access point or any connection to a
wired network. This mode is useful for quickly and easily setting up a wireless network anywhere that a wireless
infrastructure does not exist or is not required for services, such as a hotel room, convention center, or airport, or
where access to the wired network is barred (such as for consultants at a client site).
