NETWORK
CONFIGURATION AND
PLANNING
SMCs EZ Connect Wireless Solution supports a
standalone wireless network configuration as
well as an integrated configuration with 10Mbps
Ethernet LANs.
The SMC wireless network cards, adapters,
Access Point and Wireless Bridge can be
configured as:
 Ad hoc for departmental or SOHO LANs
 Infrastructure for enterprise LANs
 Infrastructure for inter-building LANs
Network Topologies
Ad Hoc Wireless LAN (no AP or
Bridge)
An ad hoc wireless LAN consists of a group of
computers, each equipped with a wireless
adapter, connected ia 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.

Infrastructure Wireless LAN
The SMC2682W can also pro ide access to a
wired LAN for wireless workstations. An
integrated wired and wireless LAN is called an
Infrastructure configuration. A Basic Ser ice Set
(BSS) consists of a group of wireless PC users,
and an Aaccess Point that is directly connected
to the wired LAN. Each wireless PC in this BSS
can talk to any computer in its wireless group ia
a radio link, or access other computers or
network resources in the wired LAN
infrastructure ia the Access Point.
The infrastructure configuration not only
extends the accessibility of wireless PCs to the
wired LAN, but also doubles the effecti e
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 Ser ice Set (BSS) is the
communications domain for each Access Point
or Bridge. For wireless PCs that do not need to
support roaming, set the domain identifier
(SSID) for the wireless card to the BSS ID of the
Access Point to which you want to connect.
Check with your administrator for the BSS ID of
the Access Point or Bridge 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 Ser ice Set (ESS). By placing the
Access Points so that a continuous co erage area
is created, wireless users within this ESS can
roam freely. All SMC wireless network cards and
adapters and SMC2682W Wireless Bridges
within a specific ESS must be configured with
the same SS ID.

Infrastructure for Bridging between
LANs
SMCs EZ Connect Wireless Bridge is a high
speed wireless bridge that allows the connections
of two or more remote Ethernet LANs into a
single irtual LAN. To connect the separated
wired LANs, there are two settings for the
Wireless Bridge: Bridge Master and Bridge
Sla e.
Bridges ser ing as local units are connected to
the primary backbone infrastructure and are set
to Bridge Master. Those acting as remote
Bridges, attached to a remote backbone and
communicating ia radio to the local unit, are set
to Bridge Sla e.
Point-to-Point Wireless Bridge
The Point-to-Point Wireless configuration uses
two Wireless Bridge units to connect two
indi idual LANs.

Point-to-Multipoint Wireless Bridge
When connecting three or more LANs (usually
in different buildings), each wired LAN requires
a Wireless Bridge. The local bridge needs to be
configured as a Bridge Master and each remote
unit configured as a Bridge Sla e.
Wireless Bridge with Wireless End Nodes
A Wireless Bridge, when functioning as a Bridge
Master has the capability to ser e the wireless
client nodes within range. The wireless client
de ice can establish radio contact with the
Wireless Bridge Master and ha e wireless access
to all local and remote LANs, workstations and
network resources.

TROUBLESHOOTING
Check the following items before you contact
SMC Technical Support.
1. If mobile users do not ha e roaming access
to the SMC2682W Wireless Bridge Master,
check the following:
 Make sure that all the SMC2682Ws and
wireless de ices in the ESS in which the
WLAN mobile users can roam are
