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 utilizes “white
space” spectrum in the 470–608 MHz
(TV channels 14–36) and 614–698 M
(TV channels 38–51) frequencies in
order to provide reliable, high-speed
broadband for applications where
traditional microwave solutions will not provide adequate RF
performance.
The syst
em 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 poor
performance; even for links between devices that are
theoretically in range. SC-FDE allows installations that are
more flexible, even without line-of-sight. Additionally, the RuralConnect® uses a proprietary
adaptive equalization system, allowing the system to correct for multipath fading. This ensures
reliable connections even in mountainous, forested, built-up areas where strong signal
reflections are common.

Our i
nternational 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.
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.
To ensure it never operates above the authorized power limit, the radio includes an internal RF
sensor just before the RF output switch. This sensor reads the actual RF power output. The
radio then adjusts the output across its operating band, according to the power limit set by the
FCC. All power controls are factory set; no user control is available.
