Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which
they may be set up: Infrastructure and Ad-Hoc. Choosing between these two
modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired net-
work or need to share a peripheral, such as a printer, with the wired network
computers, the wireless network should be set up in the Infrastructure mode.
The basis of Infrastructure mode centers around an access point, which serves
as the main point of communications in a wireless network. Access points
transmit data to PCs
equipped with wireless
network card, which can
roam within a certain
radial range of the access
point.
Multiple access
points can be arranged to
work in succession to
extend
the
roaming
range, and can be set up
to communicate with
your Ethernet hardware
as well.
If the wireless network is relatively small and needs to share resources only
with the other computers on the wireless network, then the Ad-Hoc mode can
be used. Ad-Hoc mode allows computers equipped with wireless transmitters
and receivers to communicate directly with each other, eliminating the need for
an access point. The drawback of this mode is in the fact that, in Ad-Hoc mode,
wireless-equipped computers are not able to communicate with computers on
