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 AzureWave 802.11 b/g USB WLAN
Module connects 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.

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 manage 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
“
hand-shake
”
is made between the new access point and the wireless device as the
computer traverses from the coverage of one access point to another.
