Related Products
11-Mbps Wireless Outdoor Bridge is part of a family of wireless networking
products that can provide an integrated solution for your wireless networking needs.
• For indoor applications: Access points, wireless workgroup bridges, wireless
Ethernet clients, and wireless adapters with various bus interfaces (PCMCIA,
USB, and PCI).
• For outdoor applications: The 11-Mbps Wireless Outdoor Bridge connects
two independent Ethernet LANs via a radio link, making expensive outdoor
cabling unnecessary. High-gain directional antennas provide the greatest
possible transmission range.
• Management tools: 11-Mbps wireless products support the industry-standard
Simple Network Management Protocol (SNMP) and the SNMP-based
WLAN Management System, a powerful set of utilities for managing not
only devices but whole networks and inter-networks.

WLAN Management System
WLAN Management System is a powerful network management system that is fully
compatible with the industry-standard Simple Network Management Protocol
(SNMP). It features:
• Automatic discovery of all compatible devices that are configured within the
same subnet.
• Individual and batch-mode remote management of compatible devices,
including Multi-Monitor, Batch-Upgrade, Batch-Reset, and Batch-Load
Default functions. Batch-mode operation is ideal when deploying multiple
compatible products.
• A friendly end-user interface with a consistent look and feel.
Automatic Discovery of Compatible Devices
A powerful auto-discovery algorithm is built into WLAN Management System.
With a simple click on the Auto Discovery icon, all compatible devices within the
subnet will be discovered. This discovery feature is based on the following
techniques:
• DHCP client and IP recovery: The Outdoor Bridge has a built-in DHCP
client, and will request an IP address from a DHCP server so that SNMP
management can be carried out. Should there be a failureof the DHCPserver,
the Outdoor Bridge will auto-assign itself an IP address (see next) and then
automatically negotiate for a new IP address when the server recovers.
• Auto-IP: When the Outdoor Bridge cannot get an IP address from a DHCP
server, it will auto-assign itself an IP address of 169.254.x.x and a subnet
mask of 255.255.0.0. A Windows-based system configured as a DHCP client
will use the same algorithm to assign itself an IP address in the same subnet.
When the DHCP server comes back on line, users may need to renew their
stations’IP settings as described below; otherwise, Windows may continue
to use the previous IP address instead of executing the auto-IP procedure.

WLAN Management System Hardware and Software
Requirements
System requirements for installing and operating the WLAN Management System
are:
• An x86-based microcomputer running Microsoft Windows 95, 98, Me, NT
4.0, 2000, or XP
• Microsoft Internet Explorer 4.01 or later
• A connection to an Ethernet network
Particular versions of Windows have the following additional requirements:
1. On Windows 95, Microsoft DCOM95 must be installed. You can obtain
DCOM95 from the following Microsoft Web page:
http://www.microsoft.com/com/dcom/dcom95/download.asp
DCOM95 can also be found on the Microsoft Visual Basic 5.0 CD-ROM
(Enterprise, Professional, or Standard edition), in the directory
\Pro\Tools\DCOM95.
2. On Windows 98 (with the exception of Windows 98SE, which already
includes this component), Microsoft DCOM98 must be installed. You can use
the following link to download it:
http://www.microsoft.com/com/dcom/dcom98/download.asp
3. On Windows NT 4.0, Service Pack 4 or later must be installed.

Terminology Used in this Guide
BSSID, MAC ID
The BSSID (Basic Service Set ID) is a factory-set ID unique to each wireless
networking product. It is identical to the MAC ID (Media Access Control ID). It
allows each device to be identified on the wireless network.
ESSID
An Extended Service Set ID (often referred to as Service Set ID, or SSID) identifies
the wireless LAN domain that a bridge is in. A domain is generally composed of
wireless bridges in communication with each other via radio links. You can type an
existing domain name or create a new one that contains up to 32 characters. The
SSID is case-sensitive.
Regulatory Domain
11-Mbps wireless products use the license-free ISM (Industrial, Scientific, and
Medical) band to communicate through radio waves. Different countries offer
different radio frequencies to be used as the ISM band. There are four frequency
bands defined by IEEE 802.11: Japan (2.471 to 2.497 GHz), USA, Extended Japan,
Canada, and Europe (2.4 to 2.4835 GHz), Spain (2.445 to 2.475 GHz), and France
(2.4465 to 2.4835 GHz). To use 11-Mbps wireless products in a country not listed
above, check with your government’s regulating body to find the correct frequency
band to use. All 11-Mbps wireless products are supplied preset to the country of
sale’s frequency band.
WEP
WEP stands for Wired Equivalent Privacy. It is an encryption scheme that provides
secure wireless data communications. WEP uses a 40-bit or 128-bit key to encrypt
data. In order to decode the data transmission, all wireless clients on the network
must use identical keys.

How to Use this Guide
This user’s guide gives complete instructions for installation and use of the 11-Mbps
Wireless Outdoor Bridge.
Wireless Outdoor Bridge is supplied with factory set default network settings. Use
the WLAN Management System tool to change the default settings before
introducing a new bridge to an already-established wireless network.
The WLAN Management System is a simple-to-use, yet extremely powerful,
SNMP-based utility for online central configuration and network management from
a remote station on the same subnet. A trap management program is also provided to
monitor/diagnose the Outdoor Bridge.
Read through the next section ‘Planning the Network’, in order to get the best
possible performance from the 11-Mbps wireless network.
Step 1: Plan the wireless network See “Planning the Network,” for details.
Step 2: Pre-configure the bridge
before installing it into
an existing Ethernet
network
See “Hardware Configuration,” for details.
Step 3: Install the bridge into the
Ethernet network See “Installing the WLAN Management
System,” for details.
Step 4: Make online
configuration and
manage the bridge via
the WLAN Management
System utility
See “Using the WLAN Management System,”
for details.

Planning the Network
The Wireless Outdoor Bridge is used to connect two separate networks via radio
waves. A typical application is shown below.
Figure 1. Typical application scenario
The bridge connects to your existing wired or wired/wireless local area network as
shown below (Figure 2).

Hardware Configuration
Before adding a Wireless Outdoor Bridge to an existing Ethernet network, you need
to carry out basic configuration, e.g., set the SSID, security (WEP) parameters,
bridge mode (including the peer bridge’s MAC address), channel number, and IP
address in order to make the bridge compatible with the existing network.
Figure 4. Wireless Outdoor Bridge Solution Installation

11-Mbps Wireless Outdoor Bridge

Pre-configuration can be carried out through WLAN Management System. As long
as the outdoor bridge and the management station are on the same physical Ethernet
LAN, WLAN Management System’s Kick Start function will find the outdoor
bridge and let you set basic parameters. Make connections as follows:
step 1. Using the supplied Category 5 waterproof cable, connect the waterproof
connector port of the outdoor bridge to the ODU port of DC injector.
step 2. Using Category 3 or higher UTP or STP cable, connect the RJ-45 port of
DC injector to a 10- or 10/100-Mbps Ethernet hub or switch, and connect
the management station to a hub or switch on the same LAN.
step 3. Connect the output cord of the power adapter to the DC injector’s DC
input jack, and plug power adapter into an AC outlet to power up the
outdoor bridge (see Figure 4 and Figure 5).

11-Mbps Wireless Product Placement Guidelines
A few tips to mention that are particularly significant in a radio wave
communications system:
1. Radio waves reflect or refract from buildings, walls, metal furniture, or other
objects. This could result in performance degradation due to the fluctuation of
the received signal.
2. Microwave ovens use the 2.45 GHz frequency band. 11-Mbps wireless devices
also functions in the 2.4 ~ 2.5 GHz band, and therefore shares some of the band
with microwave ovens. This means that when a nearby microwave oven is in
use, it may interfere with 11-Mbps wireless signals, resulting in performance
degradation on the wireless network.
Antenna Alignment
For the best performance, adjust the position of the antenna until an optimal signal
quality results (see Antenna Alignment Utility for details).
