About Wireless LAN 1-2
Ad-hoc mode
In an Ad-hoc network, also known as a Peer-
to-Peer network, each workstation in the
network is both a server and a wireless client.
Users on the network can share files,
printers, drives and other peripherals, and
access the Internet using a shared modem,
as shown in Figure 1-1. However, users can
only communicate with other WLAN
computers that are in the WLAN workgroup
and that are within a fixed range.
Infrastructure mode
In an Infrastructure network,
wireless clients connect to an
access point that is connected to
a wired LAN, as shown in Figure
1-2. The access point allows a
user on a wireless LAN to access
an existing wired network, to
connect to the Internet, E-mail,
transfer files, and to share a
printer. Moreover, the access
point manages the bandwidth to
maximize bandwidth utilization.
Flexibility
Adding new users and rearranging office space is convenient as it does not require
any additional wiring.
