9 About Wireless LANs
This Chapter provides some background information
about using Wireless LANs (WLANs).
9.1 Modes
Wireless LANs can work in either of two (2) modes:
• Ad-hoc
• Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired
(Ethernet) LAN. Wireless Stations (e.g. notebook PCs with
wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to
connect Wireless Stations (e.g. Notebook PCs with wireless
cards) to a wired (Ethernet) LAN. The Wireless Stations can then
access all LAN resources.
Access Points can only function in "Infrastructure"
mode, and can communicate only with Wireless
Stations which are set to "Infrastructure" mode.
