About the Quick Installation Guide

This Quick Installation Guide is intended to guide professional installers to install

and configure the Wireless Ethernet Extender. It covers procedures to assist you in

avoiding unforeseen problems.

1. Overview

1.1 Introduction

The Wireless Ethernet Extender is a 2x2 outdoor access point. The LWE120A

operates at 2.4-GHz band. Ideally suited for SMB or hotspot networks, this

breakthrough innovation provides superior Wi-Fi network solutions at significantly

lower cost.

In addition, the easy-to-install Wireless Ethernet Extender is also a high-

performance last-mile broadband solution that provides reliable wireless network

coverage for outdoor broadband application.

Chapter 2: Preparing for Installation

2. Preparing for Installation

This chapter describes safety precautions and product information you have to

know. Read this chapter before installing the Wireless Ethernet Extender.

Professional Installation Required

Seek assistance from a professional installer who is well trained in RF installation

and knowledgeable in the local regulations.

Safety Precautions

To keep you safe and install the hardware properly, read and follow these safety

precautions.

1. If you are installing the Wireless Ethernet Extender for the first time, for your

safety as well as others’, please assistance from a professional installer who has

received safety training on the hazards involved.

2. Keep safety as well as performance in mind when selecting your installation

site, especially where there are electric power and phone lines.

3. When installing the Wireless Ethernet Extender, note the following things:

• Do not use a metal ladder;

• Do not work on a wet or windy day;

• Wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt

or jacket.

4. When the system is operational, avoid standing directly in front of it. Strong RF

fields are present when the transmitter is on.

Installation Precautions

To keep the Wireless Ethernet Extender well while you are installing it, read and

follow these installation precautions.

1. Users MUST use a proper and well-installed grounding and surge arrestor with

the Wireless Ethernet Extender; otherwise, random lightning could easily cause

fatal damage to the unit.

WARNING: EMD (Lightning) DAMAGE IS NOT COVERED UNDER

WARRANTY.

2. Users MUST use the power cord and PoE injector shipped in the box with the

Wireless Ethernet Extender. Using other options will damage the unit.

Using the Grounding Wire

The extender has a grounding wire. Be sure to connect the extender, cables, and

PoE injector to earth ground properly during normal use to protect against surges

or ESD.

Ethernet Extender.

Figure 3-4. Grounding point on the extender.

2. Put the grounding wire on the grounding point at the bottom of the Wireless

Ethernet Extender. Then screw the grounding wire to tighten up.

Chapter 3: System Installation

Install the External Antenna

The Wireless Ethernet Extender provides two reverse SMA antenna connectors for

connecting the external antennas.

Figure 3-6. External antenna connectors.

1. Connect your external antennas to the SMA-type connectors on top of the

Wireless Ethernet Extender. For longer distance, we recommend using

higher-gain antennas to best suit the application.

Figure 3-7. External antennas connected to the extender.

WARNING: Users MUST power off the extender first before connecting the

external antennas to it. Do not power on the device without physically

attaching the antenna; otherwise, your extender might be damaged.

2. Bend the antenna to 90 degrees or 45 degrees.

90°

45°

Figure 3-8. Bend antenna.

3. You may turn one antenna 45 degrees to the left and the other 45 degrees to

the right. The tilted antennas couple together much less than if they are both

pointed in the same direction.

NOTE: Align the polarization of the antennas properly. Maximum signal strength

between bridges occurs when both antennas are using identical

polarization.

4. Tighten the connector joint clockwise to fix the antennas.

Figure 3-9. Tighten the connector clockwise.
