Introduction

SPEEDLAN 4100 & 4200 Installation and Operation User Guide
1-2 Introduction
Features and Benefits
SPEEDLAN 4100 and 4200 are wireless Ethernet brouters. Similar in function to other SPEEDLAN
products, the 4100 and 4200 differ in how they are installed. Using a unique pole mount design,
the 4100 and 4200 allow up to 300 feet of cable to be run from the connection point to the
network up to the RF device, without introducing loss of any radio signal. This increases the effective
wireless link distance and reduces or even eliminates the need for an amplifier in the system.
The outdoor mounted 4100 and 4200 are connected to the network using an indoor junction box.
This small box combines the Ethernet signal and DC power which is then run over a single Teflon
jacketed Ethernet cable up to the RF device.
These radios operate in the 2400MHz to 2483.5MHz ISM band, contain 11 user selectable RF
channels. The radios use direct sequence spread spectrum with a QPSK modulation, and employ 11
dB of processing gain.
The SPEEDLAN 4100 & 4200 brouters also contain transparent Ethernet bridging and IP routing as
described below.
Transparent Ethernet Bridging with Advanced Filtering for Security and
Network Reliability
SPEEDLAN 4100 & 4200 brouters support what is known as Transparent Ethernet Bridging with no
Spanning Tree or Source Routing support. Since the SPEEDLAN 4100 & 4200 provide network
security between a local LAN and a campus or enterprise wide network, and since using multiple
bridges in a Spanning Tree could compromise this security, the Spanning Tree scenario is not
supported. In addition, the SPEEDLAN 4100 & 4200 can filter packets based on protocol type or
MAC address pairings. These features can add a significant measure of security and network
reliability to a network interconnection.
IP Routing with Advanced Filtering for Security
The SPEEDLAN 4100 & 4200 support IP Routing in addition to bridging. It can be used to add
routing capability when an IP router may be a more appropriate choice.

Introduction 1-3
SNMP Management
SNMP wireless and wired link management may be administered from any Ethernet network or
remotely from the Internet. The SNMP MIB II, Bridge MIB, and Ethernet-Interface MIB come with the
brouters, so you can use SNMP to monitor a number of SPEEDLAN parameters, including RF-signal
quality and noise level.

1-4 Introduction
Wireless Multipoint Protocol
Campus Cell PRC features provide multipoint networking, improved performance, and increased
reliability. In multipoint networks, a SPEEDLAN 4100 acts as a central base station with responsibility
to manage the flow of data within the radio cell. When necessary, packets are repeated or
retransmitted by this brouter, allowing communications between multiple remote networks by using
SPEEDLAN 4200.
Additional Functionality for SPEEDLAN 4100 & 4200
•RF cable loss is negligible
•Brouters can be mounted in more remote locations because Ethernet cable is connected to
the brouters
•Increased RF power to the antenna will mean longer links are possible without using an
amplifier

2-2 Quick Start
System Description
The SPEEDLAN 4100 & 4200 are high speed, long range wireless LAN brouters that provide
connectivity to remote Ethernet networks. For single point-to-point links, a SPEEDLAN 4200 can be
used in each building to create a wireless communication link. For multipoint links, a SPEEDLAN
4100 acts as the central base station, which controls the communication between multiple
SPEEDLAN 4200 brouters acting as CPE. The local brouter communicates with a remote brouter on
another LAN. This effectively creates an extended wireless network, spanning sites situated up to 25
miles apart. This enables a central Ethernet LAN to be connected with one or more branch office
LANs. A single brouter with an omnidirectional antenna, may communicate with multiple brouters to
create multipoint wireless site-to-site connectivity.
Rooftop and Tower Installations Warning
Rooftop, tower and mounted equipment (brouters) installations are extremely dangerous and
incorrect installation can result in death, injury, or property damage. These installations must be
performed by professional antenna installers only.

Installation Steps
Some installation instructions are specific to customers who purchased Installation Kits from Wave
Wireless. To view a diagram of the installation listed below, see Installation Diagram, page 2-8.
The directions below contain installation procedures for the items included in the SPEEDLAN 4100 &
4200 antenna (and amplifier) kit. If you do not have an item included in the instructions below,
contact Wave Wireless.
If you are having trouble and need a full site installation, contact Wave Wireless Networking for
services and fees.
To install the SPEEDLAN 4100 & 4200, do the following:
Step 1.Verifying Line-of-Sight
Before installing the antennas and brouters, make sure a clear line-of-sight exists. Line-of-sight can
be defined as each antenna clearly seeing the other antenna, and seeing the remote locations when
viewing from the central base location. Be sure to look level with the center of origin of the
transmission (i.e., the middle of the antenna). Repeat this procedure from the remote location. Any
disruption of the signal path due to trees, building, or any other obstructions may cause the link to
function incorrectly. If you see any obstructions between two antennas, move one or both antennas
to another location.

Step 2. Mounting the Antenna
Follow the instructions below to mount the antenna.
Note: You can use a 24db grid antenna to achieve a link as long as the remote brouter can
hear it.
a) On a side-building mount, position the bracket so there will be at least three feet (one
meter) above the roof line where the pole is attached. This enables room for the antenna
and reduces signal loss from building reflection.
Note: It is not recommended to mount the antenna onto any unstable object. For more infor-
mation on antennas, see Polarizations on a Grid Antenna, page 2-9.
b) Allow for as much space between the wall brackets as possible while maintaining the
appropriate antenna height. For extended poles, additional wall brackets may be necessary.
c) Assemble the antenna and mount it to the pole using the included U-bolt antenna mounting
hardware. For a semi-parabolic grid type antenna, align the grid to run parallel with the
grid on the tip of the antenna horn. Preferably, the grid should be horizontal (or parallel to
the ground). Make sure all bolts and screws are fastened tightly.
d) Fasten the pole to the brackets. Position the antenna, point it in the appropriate direction,
and tighten the screws. Then, aim the antenna so it is pointed toward the receiving antenna
on the other building. The radio signal radiates from the end of antenna like a wide-
beamed flashlight. For optimal performance, you may need to test your link using both
polarities. This configuration option varies with each location, as well as RF signals that may
be present in the area.

Quick Start 2-5
Step 3. Mounting the SPEEDLAN 4100 or 4200 Brouter
Select one of two options below:
•Option A: Pole Mount
On a pole mount, position the brouter 5 to 10 feet below the antenna. Then, attach the
brouter to the mounting pole using two included U-bolt clamps, one on the top of the
brouter and the other on the bottom of brouter. Make sure you tighten the screws on the
back of the pole mount.
OR
•Option B: Wall or Concrete Mount
On a side building mount, position the brouter 5 to 10 feet below the antenna. Then,
attach the brouter to the wall or concrete by using the concrete or wood mounting screws.
Make sure the brouter is secured.
Step 4. Running and Securing All Cable
The installation kit includes two cables with ready-made connectors to fit your particular installation
needs such as:
•Pigtail (12" adapter from brouter)
•(1) 5-10' antenna cable (attaches to antenna one end and to lightning arrestor other end)
•Lighting arrestor (attaches to pigtail and to antenna cable)
a) Attach the 24" pigtail to the SPEEDLAN brouter to the appropriate port.
b) Attach the 10' length of cable to the antenna. Next, attach the lightning arrestor to the lower
end of the antenna cable.
c) Attach the other end of lightning arrestor to 24" pigtail.
d) Run the main length of the specialized Ethernet cable from the SPEEDLAN brouter to the
indoor junction box located inside the building).
e) Secure the cable with zip ties or cable clamps during this procedure.
When running the cable through walls or obstructions, make sure that there is ample room for
the connector to pass through without being damaged. Also, do not create extra pressure that
would cause the cable to kink or be stretched or cut (i.e., pulling cable through tight locations).

SPEEDLAN 4100 & 4200 Installation and Operation User Guide
2-6 Quick Start
f) Create a proper weatherproofing seal on all outdoor connections by wrapping it with
electrical tape and sealing it with putty. This is the most crucial step of the installation. If this
procedure is not completed, long-term and complex problems could occur. For more infor-
mation on implementing this procedure, see Weatherproofing Connectors, page 2-6.
g) Next, ground the lighting arrestor. For more information, see Grounding the Lightning Arres-
tor, page 2-6.
Step 5. Grounding the Lightning Arrestor
a) Mount the lightning arrestor to a solid surface.
b) Run the grounding wire from the lightning arrestor to a proper ground source such as a
grounding rod or roof ground wire. The lightning arrestor is NOT waterproof.
Step 6. Weatherproofing Connectors
a) Seal the entire lightning arrestor with the black waterproof sealant insulation putty that is
included in the installation kit.
b) Apply two layers of electrical tape to the connector, and leave approximately 3 inches of
cable exposed on either side of the connector. An alternative is to begin at the lowest point,
so the tape overlaps from bottom to top creating a shingled effect. (This creates an effective
barrier against water runoff). Apply this "shingle effect" to each layer of the sealing process.
c) Apply one layer of insulation putty over the top of the electrical tape, and leave at least one
inch of the cable jacket to ensure a good seal. Do not stretch the putty, as this causes thin-
ning and reduces the effectiveness of a good seal.
d) Apply five layers of electrical tape over the insulation putty and extend at least one (1) inch
past the putty. This is the most important step in creating a watertight seal. Make sure that
there are no wrinkles in the tape and the final wrap must be completed from bottom to top.
Step 7. Connect the Wireless SPEEDLAN Brouter to the Power Supply
a) Connect power cord of AC-DC 18 Vdc adapter to 110 or 220 Vac power outlet (the input
voltage of this universal adapter can vary from 100 to 240 Vac).
b) Connect the DC output of the adapter (18 Vdc) to DC jack on the indoor junction box.

Step 8. Connect the Wireless SPEEDLAN Brouter to Customer's Ethernet LAN
a) Connect the RJ-45 connector on a standard Ethernet CAT5 cable to the RJ-45 port (color of
port is white) on indoor junction box.
b) Connect the other end of the Ethernet CAT5 cable to your Ethernet hub, switch or router.
Step 9. Adding Additional Brouters
Repeat the steps above for all of The SPEEDLAN 4100 & 4200 brouters that will be communicating
with this one.

Polarizations on a Grid Antenna
The antenna must be aimed so that when you look out from the center of the antenna it is pointing
toward the receiving antenna on the other building. The radio signal radiates from the end of the
antenna like a wide-beamed flashlight.
Vertical Polarity Horizontal Polarity
In order for the antennas to operate correctly, the polarities must match!
For most applications we have found that horizontally polarized antennas work best. This is because
most other signals that may cause interference are vertically polarized. If you use horizontal
polarization, you can reduce the interference caused by those other signals.
