About Wireless Network Technology
● Select a Wireless Network Mode

● Identify a Wireless Network
A wireless network connects computers without network cables. Instead
computers use radio communications to send data between each other. You
can communicate directly with other wireless computers, or connect to an
existing network through a wireless access point. When you set up your
wireless adapter, you select the operating mode for the kind of wireless
network you want. You can use your Intel(R) PRO/Wireless Network
Connections adapter to connect to other similar wireless devices that comply
with the 802.11 standard for wireless networking.
Select a Wireless Network Mode
Wireless networks can operate with or without access points, depending on
the number of users in the network. Infrastructure mode uses access points
to allow wireless computers to send and receive information. Wireless
computers transmit to the access point, the access point receives the
information and rebroadcasts it to other computers. The access point can also
connect to a wired network or to the Internet. Multiple access points can work
together to provide coverage over a wide area.
