The versatile Wireless Ethernet Bridge can make any wired Ethernet-equipped
device a part of your wireless network. At home, use the Wireless Ethernet
Bridge to connect to game consoles, set-top boxes, or computers into your
wireless network to share your high-speed network connection. In the office,
convert your Ethernet-wired printer , scanner , camera, notebook, or desktop into
a wireless networked device.
It’s completely driver-free, so it works on any platform and under any operating system! Since there are no drivers to load, setup is a snap—just plug it into
your device and configure the network settings through your web browser.
You can also use the Wireless Ether net Bridge as a kind of “cable-less cable”
to connect remote areas together. Maybe Shipping is all the way across the
warehouse from Receiving. Or maybe you want to set up a home office in your
detached garage. With a Wireless Ethernet Bridge in the garage, and another
one (or a Wireless Access Point) in the house, you’re connected—with no
cabling hassle.

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 network 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 (see Figure 3-1).
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.
Ad-Hoc versus Infrastructure Mode

Chapter 3: Planning You r
Wireless Network
Network Topology
A wireless LAN is exactly like a regular LAN, except that each network device
in the LAN uses a Wireless Ethernet Bridge to connect to the network without
using wires. Computers in a wireless LAN must be configured to share the
same radio channel.
The Wireless Ethernet Bridge provides LAN access for wireless network
devices. An integrated wireless and wired LAN is called an Infrastructure configuration. A group of Wireless Ethernet Bridge users and an access point compose a Basic Service Set (BSS). Each PC equipped with an Wireless Ethernet
Bridge in a BSS can talk to any computer in a wired LAN infrastructure via the
Bridge.
An infrastructure configuration extends the accessibility of a Wireless Ethernet
Bridge to a wired LAN, and doubles the effective wireless transmission range
for two Wireless Ethernet Bridge PCs. Since the access point is able to forward
data within its BSS, the effective transmission range in an infrastructure LAN
is doubled.
The use of a unique ID in a Basic Service Set is essential.
The Wireless LAN infrastructure conf iguration is appropriate for enterprisescale wireless access to a central database, or as a wireless application for
mobile users.
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Ser vice Set (ESS). This continuous network allows users to roam freely within an ESS. All Wireless
Ethernet Bridge PCs within one Extended Service Set must be configured with
the same SSID.
Selecting a feasible radio channel and optimum access point position is recommended. Proper access point positioning combined with a clear radio signal
will greatly enhance performance.

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 that in Ad-Hoc mode, wireless-equipped computers are not able
to communicate with computers on a
wired network. And, of course, communication between the wireless-equipped computers is limited by the distance and
interference directly between them.
Figure 3-2 shows a typical scenario of four Wireless Ethernet Bridges in ad-hoc
mode. Figure 3-3 shows a typical wireless bridging scenario using two Wireless
Ethernet Bridges. Each wireless network is connected to a Wireless Ether net
Bridge through a switch. A separate notebook computer is equipped with a
wireless PC card and can communicate with both wireless networks as long as
it has the same SSID and channel as both wireless networks.

II position if you are connecting the Bridge to a hub or switch.
3. Plug the other end of the Ethernet network cable into the RJ-45 port on the
PC you wish to use to configure the Bridge.
4. Plug the supplied power cable into the Power port on the back panel of the
Bridge. Then plug the other end into an electrical outlet.
5. Proceed to the next section, “Chapter 5: Setting Up the Wireless Ether net
Bridge.”
6. After configuration, unplug the Ether net network cable from the PC, and
plug it into the RJ-45 port on the Ethernet-ready network device you wish
to add to the wireless network.
The hardware installation is complete.

a PC on your wired network. You can also set up the Bridge through one of
the PCs on your wireless network. Click the Next button to continue or the
Exit button to exit the Setup Wizard.
3. The screen shown in Figure 5-3 displays a list of Wireless Ethernet Bridges
on your network, along with the status information for each Bridge. (If you
have only one Bridge on your network, it will be the only one displayed.)
Select the Bridge you are currently installing by clicking its name in the
Selection box. Write down the IP address of the Wireless Ethernet Bridge,
so you can use it to access the Web-based Utility later. Click the Yes button
to continue or the Exit button to exit the Setup Wizard.

6. The Basic Settings screen will now appear. Enter your wireless network’s
SSID, and select the Channel at which the network broadcasts its wireless
signal. Enter a unique Bridge Name for the Bridge. Then click the Ne xt button to continue or the Back button to return to the previous screen.
• SSID - The SSID is the unique name shared among all points in a wireless
network. The SSID must be identical for all points in the wireless network.
It is case-sensitive and must not exceed 32 alphanumeric characters, which
may be any keyboard character (do not use any spaces). Make sure this setting is the same for all points in your wireless network.
• Channel - Select the appropriate channel from the list provided to correspond with your network settings, betw een 1 and 11 (in North America). All
points in your wireless network must use the same channel in order to function correctly.
• Bridge Name - You may assign any name to the Bridge. Unique, memo-
rable names are helpful, especially if you are using multiple bridges on the
same network.
