Limited Warranty Statement: SMC Networks, Inc. (“SMC”) warrants its products
to be free from defects in workmanship and materials, under normal use and
service, for the applicable warranty term. All SMC products carry a standard
90-day limited warranty from the date of purchase from SMC or its Authorized
Reseller. SMC may, at its own discretion, repair or replace any product not
operating as warranted with a similar or functionally equivalent product, during the
applicable warranty term. SMC will endeavor to repair or replace any product

products may be either new or reconditioned. Any replaced or repaired product
carries either a 30-day limited warranty or the remainder of the initial warranty,
whichever is longer. SMC is not responsible for any custom software or firmware,
configuration information, or memory data of Customer contained in, stored on, or
integrated with any products returned to SMC pursuant to any warranty. Products

Introduction
SMC’s EliteConnect 2.4GHz 802.11g Wireless Access Point
(SMC2552W-G) is an IEEE 802.11b/g access point that provides
transparent, wireless high-speed data communications between
the wired LAN and fixed, portable or mobile devices equipped
with a 802.11b, or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with
considerable cost savings over wired LANs (which include
long-term maintenance overhead for cabling). Using 802.11b and
802.11g technology, this access point can easily replace a
10 Mbps Ethernet connection or seamlessly integrate into a
10/100 Mbps Ethernet LAN.
In addition, the access point offers full network management
capabilities through an easy to configure web interface, a
command line interface for initial configuration and
troubleshooting, and support for Simple Network Management
tools, such as SMC’s EliteView.
Radio Characteristics – The IEEE 802.11b/g standard uses a
radio modulation technique known as Orthogonal Frequency
Division Multiplexing (OFDM), and a shared collision domain
(CSMA/CA). It operates at 2.4 GHz for connections to 802.11g
clients.
IEEE 802.11g includes backward compatibility with the IEEE
802.11b standard. IEEE 802.11b also operates at 2.4 GHz, but
uses Direct Sequence Spread Spectrum (DSSS) modulation
technology to achieve a communication rate of up to 11 Mbps.

Introduction
Component Description
Antennas
The access point includes two antennas for wireless
communications. The signal transmitted from both antennas is
identical, but only the best signal received on one of the antennas
is used. The antennas transmit the outgoing signal as a toroidal
sphere, so the antennas should be adjusted to different angles to
provide better coverage. For further information, see “Positioning
the Antennas” on page 2-3.
LED Indicators
The access point includes
three status LED indicators,
as described in the following
figure and table.

Security Slot
The access point includes a Kensington security slot on the rear
panel. You can prevent unauthorized removal of the access point
by wrapping the Kensington security cable (not provided) around
an unmovable object, inserting the lock into the slot, and turning
the key.
Console Port
This port is used to connect a console device to the access point
through a serial cable. This connection is described under
“Console Port Pin Assignments” on page C-4. The console
device can be a PC or workstation running a VT-100 terminal
emulator, or a VT-100 terminal.
Ethernet Port
The access point has one 10BASE-T/100BASE-TX RJ-45 port
that can be attached directly to 10BASE-T/100BASE-TX LAN
segments. These segments must conform to the IEEE 802.3 or
802.3u specifications.
1-5
Introduction
This port uses an MDI (i.e., internal straight-through) pin
configuration. You can therefore use straight-through twisted-pair
cable to connect this port to most network interconnection
devices such as a switch or router that provide MDI-X ports.
However, when connecting the access point to a workstation or
other device that does not have MDI-X ports, you must use
crossover twisted-pair cable.
The access point appears as an Ethernet node and performs a
bridging function by moving packets from the wired LAN to
remote workstations on the wireless infrastructure.
Note: The RJ-45 port also supports Power over Ethernet (PoE) based
on the IEEE 802.3af standard. Refer to the description for the
“Power Connector” for information on supplying power to the
access point’s network port from a network device, such as a
switch, that provides Power over Ethernet (PoE).
Reset Button
This button is used to reset the access point or restore the factory
default configuration. If you hold down the button for less than 5
seconds, the access point will perform a hardware reset. If you
hold down the button for 5 seconds or more, any configuration
changes you may have made are removed, and the factory
default configuration is restored to the access point.
Power Connector
The access point does not have a power switch. It is powered on
when connected to the AC power adapter, and the power adapter
is connected to a power source. The access point automatically
adjusts to any voltage between 100-240 volts at 50 or 60 Hz. No
voltage range settings are required.
The access point may also receive Power over Ethernet (PoE)
from a switch or other network device that supplies power over
the network cable based on the IEEE 802.3af standard.
1-6
Features and Benefits
Note that if the access point is connected to a PoE source device
and also connected to a local power source through the AC
power adapter, PoE will be disabled.

Network Configuration
The wireless solution supports a stand-alone wireless network
configuration as well as an integrated configuration with
10/100 Mbps Ethernet LANs.
Wireless network cards, adapters, and access points can be
configured as:
• Ad hoc for departmental, or enterprise LANs
• Infrastructure for wireless LANs
• Infrastructure wireless LAN for roaming wireless PCs
The 802.11b and 802.11g frequency band which operates at
2.4 GHz can easily encounter interference from other 2.4 GHz
devices, such as other 802.11b or g wireless devices, cordless
phones and microwave ovens. If you experience poor wireless
LAN performance, try the following measures:
• Limit any possible sources of radio interference within the
service area
• Increase the distance between neighboring access points
• Decrease the signal strength of neighboring access points
• Increase the channel separation of neighboring access points
(e.g., up to 3 channels of separation for 802.11b or up to 5
channels for 802.11g)

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 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.

Network Topologies
Infrastructure Wireless LAN
The access point also provides 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.

Network Configuration
Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) defines the communications domain
for each access point and its associated wireless clients. The
BSS ID is a 48-bit binary number based on the access point’s
wireless MAC address, and is set automatically and transparently
as clients associate with the access point. The BSS ID is used in
frames sent between the access point and its clients to identify
traffic in the service area.
The BSS ID is only set by the access point, never by its clients.
The clients only need to set the Service Set Identifier (SSID) that
identifies the service set provided by one or more access points.
The SSID can be manually configured by the clients, can be
detected in an access point’s beacon, or can be obtained by
querying for the identity of the nearest access point. For clients
that do not need to roam, set the SSID for the wireless card to
that used by the access point to which you want to connect.
