Chapter 1 Introduction
The R2 Extender is a high-performance outdoor-deployable wireless bridge that provides
wireless connectivity among multiple network locations. It supports Base Station, CPE, PTP and
PTMP connectivity. Moreover, the R2 Extender has a built-in 23dBi planar antenna that can
deliver up to a 40Km connection. An external antenna may also be used to improve signal
quality, extend distance and flexible for local coverage applications. With high throughput and
long-distance transmission, the R2 Extender is an ideal backhaul solution for Carriers, Service
Providers and Enterprises!

Chapter 2 Preparation before Installation
This chapter describes safety precautions and product information you have to know and check
before installing R2 Extender.
Professional Installation Required
1. Please seek assistance from a professional installer who is well trained in the RF installation
and knowledgeable in the local regulations.
2. The R2 Extender is distributed through distributor and system installer with professional
technicians and will not be sold directly through retail store.
Safety Precautions
To keep you safe and install the hardware properly, please read and follow these safety
If you are installing an antenna for the first time, for your safety as well as others’, please
seek assistance from a professional installer who has received safety training on the
hazards involved.
Keep safety as well as performance in mind when selecting your installation site, especially
where there are electric power and phone lines.
When installing your antenna, note the following:
Do not use a metal ladder;
Do not work on a wet or windy day;
Wear shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
When the system is operational, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is on.

Connect Up
Before installing the Ethernet cable with a waterproof RJ-45 connector, it is recommended that
the Cat-5 RJ-45 coaxial cable be used for the bridge to power injector connections.
To connect to the hole labeled PoE+Data, open the black cover in advance by using a
coin or a slotted screwdriver and then screw in the body of the gland and tighten.
Slide the sealing nut to the RJ-45 cable from its middle breach and then insert the sealing
into the cable.

Ground the Wire
The R2 Extender is shipped with a grounding wire. The unit must be properly grounded to
protect against power surges. The grounding point can be found on the bottom of the unit. It is
supplied with an appropriate grounding lug for attachment to the ODU.
Power On
To power up the R2 Extender, follow the steps bellow:
Plug a user-supplied Cat-5 Ethernet cable from your wired LAN (or a computer) into the
power injector RJ-45 jack (DATA IN);
Plug a user-supplied Cat-5 Ethernet cable from the R2 Extender into the power injector
RJ-45 jack (P+DATA OUT);
Connect the power module to the power injector and plug the AC cord into an AC power
After being powered on, the device will send out the beep sound lasting about 1.5
seconds, informing you that the R2 Extender is powered up! Wait for about 60 seconds
the system will be initialized and start working.

Make sure PoE is correctly connected to the RJ-45 port on the R2 Extender labeled
PoE+Data. DO NOT connect to the port labeled “Warning!! No POE”, otherwise the
extender will be severely damaged!

Chapter 4 Configuration
Connect the R2 Extender to a Local Computer
If you are configuring the R2 Extender locally (without connecting its power injector to a wired
LAN), connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable.
Assign a static IP address to your PC which is in the same network segment with the R2
Extender. As the default IP address of this unit is, you may choose from to
Test the link status between your PC and the R2 Extender. Start a command prompt and
execute a continuous ping command “ping –t”. If ping to the wireless bridge is
successful (as shown below), open Internet browser and enter the bridge’s IP address in
the address filed and press Enter.

Considering convenient configuration, it is recommended to configure local
and remote R2 Extender respectively on two computers.
TTL time may vary depending on the operating system..

How to Establish Wireless Bridge Mode
The R2 Extender supports four operating modes, which are Base Station, CPE, Peer-to-Peer
(CSMA) and Peer-to-Peer (TDMA). Normally, Wireless Bridge is the typical mode on this unit.
Here we will illustrate how to establish wireless bridge connectivity with R2 Extender.
Enter the user name (admin) and password (password) to login and make configurations.
Due to browser’s security trusted sites, might not able to be opened.
You may choose to continue to the website.
Open “Basic Setup” in “System”, set the IP address of two R2 Extenders in the same
network segment. e.g. local R2 Extender as and remote R2 Extender as
Chapter 5 Troubleshooting
Page 14 and set the IP Subnet Mask on both as
Each IP address is unique within a LAN, otherwise IP collision may occur!
Open “Radio” in “Wireless” and you will find the default operating mode is Peer-to-Peer
(CSMA). Select RF1(WLAN1) or RF2 (WLAN2) as Bridge to make the following
configuration. Here we take RF1 as an example. Se select Peer-to-Peer (CSMA)
operating mode and keep the Channel/Frequency and Bandwidth on both R2 Extenders
identical. Click “Apply” to save settings.

Login the Web-based interface of remote R2 Extender, open “About” in “System” and
record the wireless MAC address of it, either WLAN 1 or WLAN 2 MAC Address.
Login the Web-based interface of local R2 Extender and open “Peer-to-Peer Setup” in
“Wireless”. Select “RF1” , input the WLAN1 or WLAN2 MAC address of the remote one to
“Remote MAC Address 1” field and click “Apply”;
Chapter 5 Troubleshooting
Page 16
The MAC address on the housing of R2 Extender is the ETH MAC address;
therefore it can not be used in Peer-to-Peer links.
The IP address of your PC should be in the same network segment to the one
of bridges.
Use ping to check whether the link between the two R2 Extender is OK.

To get a better wireless connectivity, antenna alignment is strongly recommended after
both R2 Extenders are installed long distance apart.
Login the Web-based interface of the local R2 Extender and open “Peer-to-Peer Setup”

in “Wireless”. Select RF1 and hit “Align Antenna” button, an antenna alignment tool will
popup. Specify the Target RSSI and click “Start” to begin the antenna alignment.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction.
During the adjustment, observe “Current RSSI” in local R2 Extender. Fix the remote
antenna when it reaches your expectation. Usually, RSSI between -60 and -70dBm
indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe
“Current RSSI” in the remote R2 Extender. Fix the local antenna when it reaches your
Congratulations! You have primarily completed configuration on R2 Extender and they can be
put into operation. For more advanced configurations, please refer to the User manual.

Chapter 5 Troubleshooting
This chapter provides troubleshooting procedures for basic problems with the R2 Extender.
Q 1. What if my R2 Extender fails to connect to the remote one?
Ethernet Link: Check the availability of power to the bridge by observing the LED
status on the power injector.
Green: The R2 Extender is connecting to the backhaul network.
Off: The R2 Extender disconnects from the wired network, check whether the power
cord and Ethernet cables to the network and bridge are correctly connected.
Basic Configurations: Mismatched basic settings among bridges are the most
common cause of connectivity fail. If the bridge does not associate with a remote
bridge, check whether in each device are identical.
Security Settings: Remote bridges attempting to authenticate to your R2 Extender
must support the same security options configured in your bridge, such as WEP and
WPA (2)-PSK. If your bridge fails to associate with others, check whether the security
settings are the same as your bridge settings.
Antenna Alignment: If the methods above are all checked to be correct, you can
observe and verify antenna alignment with RSSI value.
Q 2. What if I would like to reset the unit to default settings?
You may restore factory default settings in “Backup/Restore Settings” from “Management”
Q 3. What if I would like to backup and restore my configuration settings?
You may do the backup by generating a configuration file or retrieve the settings you have
backed up previously in “Backup/Restore Settings” from “Management”.
