1.3.1
Ad-Hoc mode
Ad-Hoc wireless networks bring together workstations and computers to act as servers to all
other users on the network without
complex infrastructure, setup or
administration. Users on the network can
share files, printers. When in ad hoc mode,
the AzureWaveIEEE 802.11 b/g
PCI-Express Wireless Moduleconnects to
another wireless device within its effective
range and communicates with each other
in the same LAN workgroup. Select this
configuration when no access point is
present in your wireless network.
1.3.2
Infrastructure mode
The biggest difference between
infrastructure mode and ad-hoc mode is
that it includes an access point. In
infrastructure mode, an access point
establishes the network that provides
wireless links in the validating range for
clients to communicate with each other
or with a wired network to the internet.
On an infrastructure network, the access
point may manag the bandwidth to
maximize utilization. Infrastructure
networking has the following advantages over ad-hoc networking:
l
Range Extension
Each wireless LAN enabled computer within the range of the access point can communicate
with other wireless LAN enabled computers within the valid range of signal from the access
point.
l
Roaming
A wireless LAN enabled computer can physically move from the operating range of one
access point to another without losing connection to the LAN. A quick association
