Network Topologies

Ad Hoc Wireless LAN

An ad hoc wireless LAN consists of a group of computers, each
equipped with one wireless adapter, connected via radio signals as
an independent wireless LAN. Computers in a specific ad hoc
wireless LAN must therefore be configured to the same radio
channel.

An ad hoc wireless LAN can be used for a branch office or SOHO
operation.

ETWORK CONFIGURATION AND PLANNING

Infrastructure Wireless LAN

The SMC2735W can also provide access to a wired LAN for
wireless workstations. An integrated wired/wireless LAN is called
an infrastructure configuration. A Basic Service Set (BSS) consists
of a group of wireless PC users, and an access point that is directly
connected to the wired LAN. Each wireless PC in this BSS can talk
to any computer in its wireless group via a radio link, or access
other computers or network resources in the wired LAN
infrastructure via the access point.

The infrastructure configuration not only extends the accessibility
of wireless PCs to the wired LAN, but also increases the effective
wireless transmission range for wireless PCs by passing their signal
through one or more access points.

A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
the following figure.

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) is the communications domain for
each EZ Connect Wireless Access Point. For wireless PCs that do
not need to support roaming, set the domain identifier (SSID) for
the wireless card to the SSID of the access point to which you
want to connect. Check with your administrator for the SSID of the
access point to which he wants you to connect.

A wireless infrastructure can also support roaming for mobile
workers. More than one access point can be configured to create
an Extended Service Set (ESS). By placing the access points so that
a continuous coverage area is created, wireless users within this
ESS can roam freely. All SMC wireless network cards and adapters
and SMC2755W Wireless access points within a specific ESS must
be configured with the same SSID.

ROUBLESHOOTING

Check the following troubleshooting items before contacting SMC
Technical Support.

Adapter Installation Problems

If your computer cannot find the EZ Connect Wireless CardBus
Adapter or the network driver does not install correctly, check the
following:

• Make sure the adapter is securely seated in the CardBus slot.
When you insert the wireless adapter into the notebook’s slot,
a click should be heard if the adapter is properly inserted.
Check for any hardware problems, such as physical damage to
the card’s connector.

• Try the card in another CardBus slot. If this also fails, test your
computer with another SMC2735W wireless card that is known
to operate correctly.

• When operating under Windows NT, make sure a CardBus
adapter and socket services driver is installed in your computer.
Also check for resource conflicts using the Windows NT
Diagnostics utility.

• Make sure your computer is using the latest BIOS.

• If there are other network adapters in the computer, they may

be causing conflict, remove all other adapters from the
computer and test the wireless adapter separately.

• Check for a defective computer or CardBus slot by trying the
adapter in another computer that is known to operate correctly.

ROUBLESHOOTING

Network Connection Problems

If the Network LED on the CardBus adapter does not light, or if
you cannot access any network resources from the computer.
Check the following:

• Make sure the correct software driver is installed for your
operating system. If necessary, try reinstalling the driver.

• Make sure the computer and other network devices are
receiving power.

• The access point you are using may be defective. Try to use
another access point.

• If you cannot access a Windows or NetWare service on the
network, check that you have enabled and configured the
service correctly. If you cannot connect to a particular server,
ensure that you have access rights and a valid ID and password.

• If you cannot access the Internet, ensure that you have
configured your system for TCP/IP.

If your wireless station cannot communicate with a computer in
the Ethernet LAN when configured for infrastructure mode, check
the following:

• Make sure the access point that the station is associated with is
powered on.

• Make sure your wireless station is configured with the same
operating radio channel as the access point.

• If you still cannot connect, change the access point and all the
stations within the BSS to another radio channel.

• Make sure the BSSID is the same as the access point for a
station with roaming disabled, or the SSID is the same as the
access point for a station with roaming enabled.

Maximum Distance Table

Important Notice

Maximum distances posted below are actual tested distance
thresholds. However, there are many variables such as barrier
composition and construction as well as local environmental
interference, that may impact actual distances and cause you to
experience distance thresholds far lower than those posted below.
If you have any questions or comments regarding the features or
performance of this product, or if you would like information
regarding SMC’s full line of wireless products, you can visit SMC’s

ERMINOLOGY

The following is a list of terminology that is used in this document.

Access Point – An internetworking device that seamlessly
connects wired and wireless networks.

Ad hoc – An ad hoc wireless LAN is a group of computers each
with LAN adapters, connected as an independent wireless LAN.

Backbone – The core infrastructure of a network. The portion of
the network that transports information from one central location
to another central location where it is unloaded onto a local
system.

Base Station – In mobile telecommunications, a base station is the
central radio transmitter/receiver that maintains communications
with the mobile radiotelephone sets within its range. In cellular
and personal communications applications, each cell or micro-cell
has its own base station; each base station in turn is
interconnected with other cells’ bases.

BSS – BSS stands for “Basic Service Set.” It is an Access Point and
all the LAN PCs that are associated with it.

CSMA/CA – Carrier Sense Multiple Access with Collision
Avoidance.

ESS – ESS (ESS-ID, SSID) stands for “Extended Service Set.” More
than one BSS is configured to become an Extended Service Set.
LAN mobile users can roam between different BSSs in an ESS
(ESS-ID, SSID).

ERMINOLOGY

Ethernet – A popular local area data communications network,
which accepts transmission from computers and terminals.
Ethernet operates on a 10 Mbps base band transmission rate, using
a shielded coaxial cable or over shielded twisted pair telephone
wire.

Infrastructure – An integrated wireless and wired LAN is called
an Infrastructure configuration.

Roaming – A wireless LAN mobile user moves around an ESS and
maintains a continuous connection to the Infrastructure network.

RTS Threshold – Transmitters contending for the medium may
not be aware of each other. RTS/CTS mechanism can solve this
“Hidden Node Problem.” If the packet size is smaller than the
preset RTS Threshold size, the RTS/CTS mechanism will NOT be
enabled.

WEP – “Wired Equivalent Privacy” is based on the use of 64-bit,
128-bit or 152-bit keys and the popular RC4 encryption algorithm.
Wireless devices without a valid WEP key will be excluded from
network traffic.
