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.

3. Users MUST power off the Wireless Ethernet Extender first before connecting
the external antenna to it. Do not switch from a built-in antenna to the external
antenna from WEB management without physically attaching the external
antenna onto the unit; otherwise, the Wireless Ethernet Extender might be
damaged.

Connect up
1. The bottom of the Wireless Ethernet Extender is a movable cover. Grab the
cover and pull it back harder to take it out as the figure shown below.
Figure 3-1. Removing the bottom cover from the extender.
2. Plug a standard Ethernet cable into the RJ-45 port.

Chapter 3: System Installation
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.
1. Remove the screw on the grounding point at the bottom of the Wireless
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.
Figure 3-5. Tighten the grounding wire.
3. Connect the grounding wire to earth ground.

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.
