1.5 Network Configuration
The following part will depict the possible wireless LAN PC card network configurations, which
helps you to get a better understanding of how the wireless LAN products work together in a
wireless network.
The wireless LAN products can be configured as:
Ad-hoc (peer-to-peer) Mode
This is the simplest network configuration with several computers equipped with the PC Cards
that form a wireless network whenever they are within range of one another. In ad-hoc mode,
each client is peer-to- peer, would only have access to the resources of the other client and
does not require an access point. This is the easiest and least expensive way for the SOHO to
set up a wireless network.
