1 Introduction

The 3Com Wireless Building-to-Building Bridge lets you wirelessly connect previously
isolated, wired networks scattered across a campus of buildings. You can extend the reach
of any number of wired LANs without needing to physically lay cable between the
buildings that house them.

A wireless local area network (WLAN), can be an extension or alternative to a wired
network within a building or campus. Data is transmitted and received across the WLAN
using radio waves instead of cable. In a wireless LAN environment, no cabling is needed
between nodes for data communication. The 3Com Wireless Building-to-Building Bridge
provides a way to extend the scope of the wireless LAN far beyond the walls of a particular
building.

A 3Com Wireless Building-to-Building Bridge can be used in two network configurations,
or topologies:

Point-to-point communication

■

Point-to-multipoint communication

■

This guide explains these network topologies and their components, and leads you
through the process of installing, configuring, and administering the 3Com Wireless
Building-to-Building Bridge.

Point-to-Point Topology

Point-to-point topology is the simplest way to use your 3Com Wireless Building-to­Building Bridge. Two wireless bridges form a link between the wired LANs in two separate
buildings, as shown in the figure below. This topology typically uses only directional
antennas for communication between the two bridges (see “Antennas and Cables”
on page 3).

1

1 Introduction

Point-to-Multipoint Topology

3Com Wireless Building-to-Building Bridges can be used for communicating among
multiple (two or more) bridges, with each bridge connected to a particular building’s wired
LAN. The next figure shows a bridging network in which four 3Com Building-to-Building
Bridges are used to provide wireless connectivity among four buildings. This topology
typically uses omnidirectional antennas for communication between bridges if bridging is
desired among all buildings in the bridging network without restriction (see “Antennas
and Cables” on page 3).

In this configuration, the wireless bridges make all four wired LANs appear to be
connected by the same Ethernet cable. Using wireless bridges in this manner provides a
cost-effective way to wirelessly link multiple wired LAN networks by eliminating the need
to install cables between buildings.

An alternative point-to-multipoint configuration is shown in the following figure.

In this example, the first building’s bridge is using an omnidirectional antenna while the
other three buildings have bridges using directional antennas. In this case, the three
bridges with directional antennas can communicate only with the bridge using the omni­direction antenna; they cannot communicate directly with each other. The bridge using
the omnidirectional antenna can communicate with the other three bridges.

CAUTION:

possibly result in lower performance than a point-to-multipoint configuration that
uses only omnidirectional antennas.

This alternative, mixed-antenna point-to-multipoint topology, can

Antennas and Cables

You can connect the following types of antennas to the 3Com Wireless Building-to­Building Bridge:

■

■

For best performance, place each antenna outdoors using the mounting hardware
provided with the antenna. Outdoor placement is especially important if the building
consists of metal construction or has metal siding. If necessary, you can mount an antenna
inside a building; however, indoor placement reduces the antenna’s effective range.

The following figures illustrate the different types of antennas and typical examples of use.
See Chapter 2, “Installing the Hardware and Software,” for detailed information about
recommended 3Com antennas.

Omnidirectional Antenna

An omnidirectional antenna provides short-range, point-to-multipoint connectivity for two
or more wireless bridges. Range with an omnidirectional antenna is approximately 1300
meters at 11 megabits per second (Mbps).

Antennas and Cables

Flat-panel directional
Omnidirectional

Flat-panel Directional Antenna

A flat-panel directional antenna provides long-range, point-to-point connectivity between
two wireless bridges. Range can be as high as 4.1 kilometers (km) at 11 Mbps.

1 Introduction

Selecting an Antenna

The following table shows guidelines for selecting antennas based upon their gain
properties (expressed in decibels (dB)). The gain of any antenna is essentially a
specification that quantifies how well that antenna is able to direct the radiated radio
frequency (RF) energy into a particular direction. Thus, high-gain antennas direct their
energy more narrowly and precisely, and low-gain ones direct energy more broadly.
The range estimates listed are those that can be expected between two 3Com Wireless
Building-to-Building Bridges using the listed antenna combinations.

■

Selecting a Cable

Specific cables are available from 3Com for connecting the wireless bridge to an antenna.
In planning your bridging topology, it is important to account for signal attenuation due
to the cable and connectors used between the bridge and the antenna. Using the shortest
cables possible reduces signal loss.

3Com recommends using 50-ft cable with 18 dB antenna (with 10 dB attenuation) for
typical installations.

Cable Options

The following 3Com cables are available for use with the 3Com Wireless Building-to­Building Bridge:

3CWE480A — 6 ft

■

connectors, if necessary.

Outdoor Location

It may be necessary to mount the wireless bridge in an outdoor location. If you place the
bridge in an outdoor location, you should cover it with an optional outdoor enclosure
accessory. To obtain an outdoor enclosure accessory, contact 3Com at http://www.3com.com.
For installation instructions, refer to the procedure provided with the enclosure accessory.

2 Installing the Hardware and Software

Considering Antenna Placement

You can place the antenna either indoors or outdoors. An outdoor location, such as a
rooftop, provides the following advantages:

Fewer obstacles to signal paths between wireless bridges

■

Increased antenna range

■

Fewer multipath problems

■

Proper Grounding

To ensure the physical safety of anyone near the antenna and to prevent damage to
the wireless bridge, follow the building codes for antenna installations in your area.
This approach typically means making certain that antennas and antenna masts are
appropriately grounded to prevent injury or damage from lightning strikes.

Most of the antennas shipped with the wireless bridge do not have an electrical connection
between the mask mount and the coaxial cable shield. However, adding a lightning arrestor
will correct that situation by grounding the outer shield as recommended. In some arrestor
designs, there is also some over-voltage protection for the signal sent down the cable. If you
use such a component, be sure that it is designed to pass signals used in the 2.5 GHz signal
range (many inexpensive units are available with F connectors, but these are typically
designed for cable TV-UHF applications and may degrade the signals in the band used by
the wireless bridge).

Alignment

Position each antenna so that there are minimal obstacles between it and any other
antenna with which it will communicate. While maintaining a direct line of sight between
antennas is not strictly necessary, such an arrangement helps to ensure a strong signal.

Align each directional antenna to point at the antenna with which it will communicate.
If you place two directional antennas at different heights, tilt them up or down toward
each other for optimal signal strength. Make sure that the angle of tilt is identical for each
antenna: the antenna faces should be parallel.

While aligning the antenna, you may want to use the Wireless Bridge Manager Received
Signal Strength Indicator (RSSI) Monitor tool (preferably loaded on a mobile PC that can
be used at the antenna site) to adjust the antenna to achieve the maximum possible
received signal strength. See “Viewing Signal Strength with the RSSI Monitor” on page 36
for more information.

Polarization

Polarization is a physical phenomenon of radio signal propagation. In general, any two
antennas that are to form a link with each other must be set for the same polarization.
If for example, two antennas for a link are linearly polarized, they must both be vertically
polarized or horizontally polarized. If both antennas do not have the same polarization,
the link will either work poorly, or not at all.The situation where one antenna is vertically
polarized and the other is horizontally polarized is known as cross-polarization.

Antenna polarity should be identical for each antenna in a bridging link or network.
Vertical polarization is preferred in most cases. Make sure that every directional antenna is
properly oriented for vertical polarization (according to the polarization indicator shown
on the antenna panel).

Omnidirectional antennas should be vertically aligned in relation to the ground.
