NSTALLATION

1. Select the site – Choose a location for your Wireless Ethernet
Adapter. Usually, the best location is at the center of your
wireless coverage area, if possible within line-of-sight of all
wireless devices.

2. Place the Wireless Ethernet Adapter in a position that gives it
maximum coverage. Normally, the higher you place the
antenna, the better the performance.

3. Position the antennas in the desired positions. For more
effective coverage, position the antennas along different axes.
For example, try positioning the antennas around 45 to 90
degrees apart. (The antennas emit signals along the

toroidal plane – and thus provide more effective
coverage when positioned along different axes.)

4. If used in Ethernet Adapter mode, connect the Ethernet cable
to the RJ-45 socket of the device that will communicate over a
wireless connection with an access point.

5. If used in Acces Point mode, connect the SMC2671W to an
Ethernet network device such as a hub or a switch using
category 3, 4, or 5 UTP Ethernet cable and an RJ-45
connector. (See “Hardware Description” on page 3 for MDI/
MDI-X cabling.)

6. Connect the power adapter cable to the 5 VDC power socket
on the rear panel.

Warning: Use only the power adapter supplied with the

SMC2671W.

options are: 1, 2, 5.5, and 11 Mbps. (Default: 11)

Preamble Type The access points and client card drivers have a radio setting

for RF Preamble. If you are not sure whether all the clients and
access point radios in your wireless network support the Short
RF preamble, then leave this setting to the default (Long).

Beacon Interval The beacon signals allow the wireless devices to maintain

contact with each other. They may also carry
power-management information. (Default: 100)

RTS Threshold You may configure the access point to initiate an RTS frame.

If the packet size is smaller than the preset RTS threshold size,
the RTS/CTS mechanism will NOT be enabled. (Default: 2,347
which means Disabled)

Frag. Threshold The Fragmentation Threshold can be set between 256 and

2,346. If the packet size is smaller than the preset fragment
size, the packet will not be segmented. (Default: 2,346 which
means Disabled)

Operation Mode

Mode This may be set to Access Point, Range Extender, or Ethernet

Adapter. (Default: Ethernet Adapter)

BSSID Basic Service Set ID. The MAC address of the access point to

which the adapter is connected in an infrastructure network. In
an ad hoc network, the BSS ID is a random number generated
by the first adapter that communicates with other clients in the
network. The BSS ID of the other clients will then be set to the
same value.

The parameters that follow may be configured in any of the three
modes described above but the user is advised to leave them at
their default settings.

Transmission Rate : Set the data rate transmitted
from the Wireless Ethernet Adapter. The lower the
data rate, the longer the transmission distance.
(Default: Auto)

RTS Threshold : Set the RTS (Request to Send) frame length.
You may configure the access point to initiate an RTS frame. If
the packet size is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will NOT be enabled.

The access point sends Request to Send (RTS) frames to a
particular receiving station to negotiate the sending of a data
frame. After receiving an RTS, the station sends a CTS (Clear to
Send) frame to acknowledge the right of the sending station to
send data frames. The access points contending for the medium
may not be aware of each other. The RTS/CTS mechanism can
solve this “Hidden Node Problem.” (Default: 2347)

Fragmentation Threshold : The Fragmentation Threshold can be
set between 256 and 2,346. If the packet size is smaller than the
preset Fragment size, the packet will not be segmented.

Fragmentation of the PDUs (Package Data Units) can increase
the reliability of transmissions because it increases the probability
of a successful transmission due to smaller frame size. If there is
significant interference present, or collisions due to high network
utilization, try setting the fragment size to send smaller fragments.
This will make the retransmission of smaller frames much faster.
However, it is more efficient to set the fragment size larger if very
little or no interference is present because it requires overhead to
send multiple frames. (Default: 2346)

radio setting for for a long or short RF preamble. Preamble Type
offers a drop-down list with two options: Long or Short. Using the
short preamble can boost your throughput. If you are not sure
whether all the clients and access point radios in your wireless
network support the Short RF preamble, then leave this setting to

Infrastructure Wireless LAN

An integrated wired and 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 permits wireless clients to access
the wired LAN and also increases the effective wireless
transmission range for wireless clients as their signal can be
passed through multiple 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 wireless access point. For wireless PCs that do not need to
support roaming, set the domain identifier (SSID) of 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 wireless network cards, adapters,
and the wireless access point within a specific ESS must be
configured with the same SSID.

Note: If Access Point 2 is replaced by an SMC2671W set to

Range Extender mode then the SMC2671W will not
establish its own BSS, but will repeat data messages
between Access Point 1 and end users, thus extending
the coverage area of Access Point 1.

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 radio telephone 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).

T

ERMINOLOGY

61

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

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

Fragmentation Threshold – In the 802.11 Standard, the MAC
Layer may fragment and reassemble directed MSDUs or
MMPDUs. The fragmentation and defragmentation mechanisms
allow for fragment re-transmission.

Preamble Type – Some access points and client card drivers
have a radio setting for “Short” RF Preamble. If all the clients and
access points in your wireless network have this feature, then
enabling it can boost your throughput. However, if a radio does
not support this feature, then it will not be able to communicate
with any other radios that have this set to “Short.”

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 or
128-bit keys and the popular RC4 encryption algorithm. Wireless
devices without a valid WEP key will be excluded from network
traffic.
