Note:
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. To
avoid the possibility of exceeding radio frequency exposure limits, you shall beep a distance of at least
100cm between you and the antenna of the installed equipment. This transmitter must not be co-located
or operating in conjunction with any other antenna or transmitter.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user.

Chapter 1 Introduction
Introduction
The R2 extender is a high-performance outdoor-deployable wireless bridge that provides wireless
connectivity among multiple network locations. 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
and improve distance. The R2 Extender allows for link aggregation by combining multiple links into one
link with greater transmission rate.
The R2 Extender is a multi function communication device that supports Base Station, CPE, PTP and
PTMP connectivity. It allows for local area network (LANs) in different locations (buildings) to be easily
interconnected. The R2 Extender delivers “last mile” broadband connectivity through its PTP and PTMP
capabilities.
The R2 Extender allows to be operated on PTP mode in one card and on bridge in another. And with an
external omni antenna for bridge side may provide users with flexibility in various local coverage
applications.
With high throughput and long-distance transmission, the R2 Extender is an ideal backhaul solution for
Carriers, Service Providers and Enterprises!

Education Broadband Wireless Application
School in remote area or rural areas can be provided with broadband connectivity via local Internet service
providers The relay ability of the R2 Extender allows for multiple hops to be made thus allowing the R2
Extender to reach more remote LOS locations beyond 40Kms or to circumvent natural obstructions like
mountains..

Chapter 2 Hardware Installation
This chapter describes safety precautions and product information you have to know and check before
installing R2 Extender.
Preparation before Installation
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.
3. The equipment shall be installed in RESTRICTED ACCESS LOCATIONS. Access can only be
gained by service persons or by users who have been instructed about the reasons for the
restrictions applied to the location and about any precautions that shall be taken. Furthermore,
access is through the use of a tool or lock and key, or other means of security, and is controlled b
the authority responsible for the location.
4. If you are intended to use an external antenna with the R2 Extender, please contact your
supplier/installer to ensure that your unit is set for you have fulfilled all the local regulatory
requirements. It is the responsibility of the installer/user to check that the equipment as deployed
meets local regulatory requirements.
Chapter 2 Hardware Installation Page 16
Safety Precautions
For your safety and proper installation, please read and follow the instructions below:
ONLY qualified service personnel should service or disassemble this device;
When installing the device, note the followings:
- Do NOT use a metal ladder;
- Do NOT work on a windy or raining day;
- Do NOT install, use or service the device during a thunderstorm, as this may cause a remote
risk of electric shock from lightning;
- 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.
Ground the device properly with grounding wire to protect against lightening;
Use ONLY appropriate accessories for the device.
If the temperatures of the unit surface exceeds the limit, be precautious not to continuous held or
touch the device for a certain period of time.

respectively.
Interface Definition
The R2 Extender currently provides two interfaces at the bottom, which are PoE & Data with a black
plastic cover and RS-232 with a light gray cover that labed “WARNING! No PoE”. Among which, a
black RJ45 waterproof connector will be provided for the PoE + Data interface.

Chapter 2 Hardware Installation Page 22
Do NOT connect PoE powered Ethernet cable to the RS-232 port; otherwise the port
may burnout!
If RS-232 cable is used outdoor, please DO add a surge protector to protect the
equipment circuit!
Strongly recommend to add a lightning arrestor on the RS-232 port to prevent from
lightning attack!
Vent
The vent is designed to exclude vapors and moisture out of the unit as well as repel water, dust, and
dirt by the specially designed membrane, thereby preventing the R2 Extender from electric
malfunctioning.
