W IRELESS AP/B RIDGE
Introduction
SMC’s EZ Connect Wireless Access Point/Bridge (SMC2682W) is an
11 Mbps wireless bridge that allows two or more remote Ethernet LANs
to be merged into a single virtual LAN. Workstations on each of the
remote LANs may communicate with each other as though they were on
the same physical LAN.
The Wireless Access Point/Bridge can also function as an access point and
provide transparent, wireless data communications between the wired
LAN (and/or within the wireless network) and fixed, portable, or mobile
devices equipped with a wireless adapter employing the same radio
modulation.
This solution offers fast, reliable wireless connectivity with considerable
cost savings over wired LANs (which include long-term maintenance
overhead for cabling).

Hardware Description
Ethernet Compatibility
SMC’s EZ Connect Wireless Access Point/Bridge attaches directly to
10BASE-T (Twisted Pair) Ethernet LAN segments. These segments must
conform to the IEEE 802.3 specification.
The AP/Bridge appears as an Ethernet node and performs a routing
function by moving packets from the wired LAN to remote workstations
on the wireless infrastructure.
Radio Characteristics
The Wireless AP/Bridge uses a radio modulation technique known as
Direct Sequence Spread Spectrum transmission (DSSS), and a shared
collision domain (CSMA/CA). It operates in the 2.4 GHz license-free
Industrial Scientific and Medical (ISM) band. Data is transmitted over a
half-duplex radio channel operating at up to 11 Mbps per second.

Applications
EZ Connect wireless products offer a fast, reliable, and cost-effective
solution for wireless Ethernet client access to the network in applications
such as:
• Remote access to corporate network information
E-mail, file transfer, and terminal emulation
•Difficult-to-wire environments
Historical or old buildings, asbestos installations, and open areas
where wiring is difficult to employ
• Frequently changing environments
Retailers, manufacturers, and banks that frequently rearrange the
workplace or change location
• Temporary LANs for special projects or peak times
Trade shows, exhibitions, and construction sites that need to setup for
a short time period. Retailers, airline, and shipping companies that
need additional workstations for a peak period. Auditors who require
workgroups at customer sites
• Access to databases for mobile workers
Doctors, nurses, retailers, or white-collar workers who need access to
databases while being mobile in a hospital, retail store, in an office, or
on a campus
• SOHO users
SOHO (Small Office and Home Office) users who need quick and
easy installation of a small computer network
• Building-to-building connectivity
Connect detached sites into a single LAN, even when they are
separated by obstacles such as freeways, railroads, or bodies of water
that are practically insurmountable for copper and fiber-optic cable

LED I NDICATORS

LED Indicators
The EZ Connect Wireless Access Point/Bridge includes five status LED
indicators, as described in the following figure and table.
LED Status Description
Power On (Red) Indicates power is being supplied.
Ethernet Link On (Green) Indicates a valid Ethernet cable link.
Ethernet Activity Flashing (Orange) Indicates that the AP/Bridge is
transmitting or receiving data on the
Ethernet LAN.
Wireless Link Flashing (Green) Indicates valid Bridge Master* connection
to wireless stations. The rate of flashing
increases with the number of links.
On (Green) Indicates valid Bridge Slave* connection to
Bridge Master.
Wireless Activity Flashing (Orange) Indicates that the AP/Bridge is
transmitting or receiving data through
wireless links.

System Requirements
Before you install the EZ Connect Wireless Access Point/Bridge, be sure
you can meet the following requirements:
• An A/C power outlet (100~240 V, 50~60 Hz)
• An available RJ-45 (UTP) port on a 10BASE-T Ethernet hub or switch
• Wireless clients with IEEE 802.11b-compliant Ethernet adapters
installed
• A management station (PC) on the LAN running Windows 95/98/
2000/NT/Me/XP with the TCP/IP protocols installed
• Web browser for configuration

H ARDWARE I NSTALLATION
1. Select the Site – Choose a location for your SMC2682W Wireless
Access Point/Bridge. Usually the best place is at the center of your
wireless coverage area, within line-of-sight of all wireless devices. Try
to place the AP/Bridge in a position that can best cover its BSS (refer
to page 25). Normally, the higher you place the antenna, the better the
performance (see page 31 for the maximum distances allowed between
clients and the AP/Bridge.)
2. Attach the Antenna – Screw the antenna into the antenna connector
on the back panel.
3. Connect the Ethernet Cable – The 10BASE-T Ethernet port on the
AP/Bridge can be connected to a network device such as a hub or a
switch. Connect Category 3, 4, or 5 UTP Ethernet cable to the RJ-45
socket on the back panel.
4. Connect the Power Cable – Connect the power adapter cable to the
9 VDC power socket on the rear panel.
Warning: Use ONLY the power adapter supplied with the SMC2682W.

S YSTEM C ONFIGURATION
The diskette labeled “Utility Diskette” that comes with the package
contains a utility program for the EZ Connect Wireless Access Point/
Bridge. Updates may be downloaded from SMC’s web site at:
http://www.smc.com
Warning: Back up your utility diskette and use the copy as the working
diskette to protect the original from accidental damage.
The SMC2682W can be configured over an Ethernet network connection
via its RJ-45 port. Connect the SMC2682W to any Ethernet device such as
a hub or switch. Run the utility program and configure the unit remotely as
described below:
Windows Installation (95/98/2000/Me/NT/XP)
1. Insert the SMC2682W utility disk into the floppy drive on your PC,
and then enter the following command: “A:\utility\setup.” Follow the
on-screen instructions to install the utility program.
2. Run the installed utility, click on “AP/Bridge” and then select “Scan”
from the menu. The program will detect all SMC2682W Wireless AP/
Bridges on the network.
3. If DHCP is turned “ON” (default setting, page 20) and a DHCP
