1. Introduction
1.1. Scope of Manual
The purpose of this manual is to provide professional planning and installation personnel with
the appropriate information and procedures required to install and operate the RuralConnect®
TV White Space Broadband Radio and accessory equipment. In order to avoid harm to persons
or damage to the product, please ensure that you have read and understand the safety,
unpacking, and installation sections before proceeding.
1.2. Overview
The RuralConnect® TV White Space
Broadband Radio is designed to utilize
“white space” spectrum in the 470–608
MHz (TV channels 14–36) and 614–698
MHz (TV channels 38–51) frequencies
in order to provide reliable, high speed
broadband for applications where
traditional microwave solutions won’t provide adequate RF
performance.
The system uses state of the art Single Carrier Frequency
Domain Equalization (SC-FDE) to provide protection against
signal fading caused by multipath interference (phase-shifting)
while offering a robust clean transmit spectrum. Reflections
from trees, buildings and hills are inevitable for long range
wireless links. These reflections arrive at slightly different
times, causing deep fading across the channels used by white
space systems. Without equalization, this fading causes
performance; even for links between devices that are
theoretically in range. SC-FDE allows more flexible installations
where obstructions and foliage are known factors. Combined with a proprietary adaptive
equalization system, SC-FDE allows the system to correct for multipath fading. This ensures
reliable connections even in mountainous, forested, and/or built-up areas where strong signal
reflections are common.
Figure 2: RuralConnect® CPE Unit
In the U.S., the RuralConnect® is only available with a 6 MHz channel bandwidth. The system is
fully compliant with FCC Part 15H regulations.
Our international models ensure worldwide compatibility, regardless of the TV broadcast
technology in use. International users must ensure compliance with their regulatory authorities.
For export only, international models are available in both 6 MHz and 8 MHz versions.
2. Pre-test and System Planning
2.1. Proper Handling
You must follow precautionary measures when handling RuralConnect® devices. Improper
handling of your equipment may cause damage and void your warranty. The electronic
Page | 7
PRELIMINARY RELEASE
*** This is a confidential document. Do not distribute. ***
components of the RuralConnect® equipment are sensitive to electrostatic discharge (ESD).
Use adequate ESD protection, such as an anti-static wrist strap, whenever handling the
equipment. It is also important to avoid the use of conductive tools.
2.2. Grounding
A ground is a low impedance electrical connection to the earth utilized for energy dissipation.
Grounding the RuralConnect® is very important for safety reasons, as well as protecting the
system from damage due to lightning and/or static charge build up. Since lightning strikes and
surges are high-current and high-frequency events; short, straight ground wires (not coiled or
looped) must be used. Choose the largest diameter ground wire your ground connectors will
accept for good electrical conductivity. We recommended a #8 gauge copper wire or larger.
Utility company grounds, grounding rods, well casings, and cold water pipes constructed of
continuous metal are strongly recommended. A note of caution: sometimes repaired and/or
extended metal cold-water pipes include PVC sections hidden behind drywall. PVC will disrupt
conductivity and render the pipe unacceptable as a ground. Conductivity is often poor in desert
areas, so multiple ground rods may be required (preferably bonded together to make a suitable
connection). The impedance of your grounding should never exceed 5 Ohms. Carlson
recommends maintaining a ground with less than 3 Ohms. Undesirable grounds include, but are
not limited to, sprinkler pipes, PVC pipes, conduit, and buried wire. Never use an unverified
ground.
In order to prevent electric shock, always disconnect the remote power source and all cables
from the system prior to removing the grounding connection.
2.3. Lightning Protection
Poorly grounded lightning protection is the same as having no protection at all!
Lightning is one of the most dangerous, yet most common, natural hazards for a RuralConnect®
system. It is absolutely essential to install and maintain adequate lightning protection for your
equipment. Verified ground connections are imperative for lightning protection to work correctly.
Primary lightning protection is located outside the enclosure. Install primary lightning protection
with a good ground on all RF and/or data connections that have even a moderate outdoor line
build-out. Best practices dictate all lines entering or exiting a building need protection. You must
use protection on both ends of the cables between buildings! Contact your sales representative
for detailed specifications and usage information for the primary lightning protection solutions
available from Carlson.
In areas with frequent lighting activity, augmenting the client station install with a nearby
lightning rod is strongly recommended. Lightning can be unpredictably strike, might miss the
antenna mast altogether, and make contact with underlying wiring/cabling instead. Lightning
discharges into the lowest impedance path to ground, i.e. earth. In many cases this will be the
master ground in the primary AC panel, unless nearby grounding is installed.
2.4. Cable Recommendations
Use of proper high-quality cabling is important to ensure the best performance for your
RuralConnect® system. Carlson extensively researched and tested cabling before selecting
those offered for RuralConnect® customers. It is recommended that you use only Carlson
approved cables. Discuss your cabling options with your Carlson Sales Representative.

2.4.1. RF Cables
Carlson carries professional-grade RF coax cables that provide greater durability and less
attenuation/loss than those readily available. We offer and recommend well-insulated 75-Ohm
broadband coaxial cable with gas-injected foam polyethylene insulation. For short jumper
connections, use 18 AWG RG-6/U cables with a solid .040” bare copper conductor. For longer
runs, use 14 AWG RG-11 cables with a .064” bare copper conductor.
Only use cables with 100% solid copper center conductors. Lower-quality copper-clad
conductors have decreased performance and can lead to failures.
75-Ohm cabling used for RuralConnect® installation cannot exceed 150-feet (45.72 meters).
Terminate all coax cables with weather-sealed 75-Ohm F-type compression connectors with
PVC jackets. Do not use crimp-type connectors.
Avoid cable bends as much as possible; do not put more than a 90-degree bend in any cable
run.
2.4.2. Data Cables
Network performance is greatly affected by the quality of the data cabling used. Carlson carries
and recommends shielded, grounded, outdoor Category-5 or higher twisted pair cable.
2.5. Recommended Tools
These are the tools needed to set up a RuralConnect® system. Make sure you have them
handy to ensure a seamless installation.

CPEs connect to a Basestation via a UHF radio signal. Due to
the unique propagation characteristics of signals in the UHF
band, good connections are generally possible even if there is a
non-line-of-sight path to the Basestation. Once a link to the
Basestation is established, CPEs provide network access via a
standard Ethernet connection.
The bottom plate of the CPE has an RF port, Ethernet port and
four (4) RSSI LEDs.

After making your desired changes, click the “Save Changes” button to apply them.
Use the “Mute” button to disable the radio on the Basestation. Place a check into the box to
enable this feature. This will disable the Basestation radio. Your RuralConnect® network will not
function with this feature enabled.
5.6.1. Modulation Modes
The performance of each RF link is determined by the
signal quality and the modulation mode used. These
drop-down menus allow you to select the modulation
mode for both the uplink and downlink of each CPE.
You can only change the setting for one station at a
time. After making changes, press the “Save Changes”
button. The changes will be applied and the Cell
Control tab will reset.
Complex modulation types are at the top of the list,
followed by simpler modulation types and various
forms of forward error correction (FEC). Complex Figure 30: Modulation Settings
Page | 21
PRELIMINARY RELEASE
*** This is a confidential document. Do not distribute. ***
modulations, such as quadrature amplitude modulation (QAM) provide a mechanism for higher
bit rates, and thus more available throughput. These complex modulations, however, have a
negative impact on the receive threshold of the radio, the signal level at which the link is
unreliable.
Modulation modes are in order of net bit rate, with the highest bit rate at the top of the list. The
effective throughput of an RF link is based on the net bit rate, less the PHY and link-layer
overheads. Modulation modes in Cell Control include acronyms for modulation types and
abbreviations for FEC types. “Conv_Punct”, a 3/4 punctured convolutional coding rate, provides
25% FEC, reducing the available payload to 75% of the gross bit rate. “Conv” is a 1/2
convolutional coding rate. This 50% FEC produces a reliable communications channel, while
reducing the available payload to 50% of the gross bit rate.
Basestations will commonly use “Qpsk_1_Conv” for the Uplink and Downlink modulation modes.
This modulation mode provides a good link reliability and provides enough bandwidth for system
controls
Set your CPE stations with the modulation mode that meets the needs of the installation and
application. Stronger signal-to-noise ratios will allow the use of higher modulation modes,
providing higher throughput. An SNR of 25 or greater will allow the use of QAM16 with FEC,
while an SNR of 30 or greater is required before you can disable FEC (“QAM16_None”).
For troubleshooting RF links with errors and/or poor signals, select a lower modulation mode.
An “Adaptive Modulation” button is available, which will enable dynamic control of the link
modulation mode, to maintain link stability in varied conditions. Although this is useful feature, a
fixed modulation type will provide better performance.
5.7. Station Properties
From many areas around the OMC, you can click on the “Id” or “Name”
hyperlink of a station to open a “Station Properties” pop-up window.
Clicking the ID will open a new webpage. Clicking the Name will open a
