Introduction
>>> 1.1 MSI PC54AG – Wireless 11a/b/g PCI Card
PC54AG (MS-6845) Wireless 11a/b/g PCI Card, compliant with IEEE802.11a/b/g, is
a high-efficiency wireless adapter for wireless networking at home, in office or in
public places. The data transmission rate can be up to 54 Mbps and auto-negotiated
to 54, 48, 36, 24, 18, 12, 9, 6 Mbps (IEEE802.11a), 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5,
2, 1 Mbps (IEEE802.11g), or 11, 5.5, 2, 1 Mbps (IEEE802.11b).
With PC54AG (MS-6845), you can roam between conference room and office without
being disconnected the LAN cables; in addition, sharing files and printers can be easy
tasks.
The PC54AG (MS-6845) is available to Microsoft Windows operating systems
(Windows
Ad-hoc mode (computer-to-computer, without an Access Point) or Infrastructure
mode (computer-to-access point, an Access Point is required).

>>> 1.2 How PC54AG Works
Ad-hoc Mode : An Ad-hoc network is a local area network, especially one with
wireless or temporary plug-in connections. Therefore, some of the network
devices are part of the network only for the duration of a communications
session. Users in the network can share files, print to a shared printer, and
access the Internet with a shared Gateway or Access Point. In this kind of
network, new devices can be quickly added; however, users can only
communicate with other wireless LAN devices that are in this wireless LAN
workgroup, and are within range.

Infrastructure Mode : The difference between Infrastructure network and
Ad-hoc network is that the former one includes an Access Point. In network
environment, the Access Point can manage the bandwidth to maximize
band-width utilization. Moreover, the Access Point enables users on a wireless
LAN to access an existing wired network, allowing wireless users to take
advantage of the wired net-works resources, such as Internet, email, file transfer,
and printer sharing. The scale and range of the Infrastructure networking are
larger and wider than that of the Ad-hoc networking.
