1 INTRODUCTION
This section provides basic description, application, and configuration information about the
Digivance Long-Range Coverage Solution (LRCS) system. Throughout this publication, all
items referenced as “accessory items” are not furnished with the basic product and must be
purchased separately.
2 LRCS SYSTEM OVERVIEW
The Digivance LRCS system is an RF signal transport system that provides long-range RF
coverage in areas where it is impractical to place an Enhanced Base Transceiver Station (EBTS)
at the antenna site. High real estate costs and community restrictions on tower and equipment
locations often make it difficult to install the EBTS at the same location as the antenna. The
Digivance LRCS system is designed to overcome equipment placement problems by allowing
base stations to be hubbed at a central location while placing antennas at remote locations with
minimal real estate requirements. With the Digivance LRCS system, RF signals can be
transported to remote locations to expand coverage into areas not receiving service or to extend
coverage into difficult to reach areas such as canyons, tunnels, or underground roadways.
2.1 Basic System Components
The basic components of a typical Digivance LRCS system and their function are shown in
Figure 1-1. A basic LRCS system consists of a Host Unit (HU) and a Remote Unit (RU). The
HU consists of a single-unit assembly that mounts in a standard equipment rack. The RU
consists of multiple electronic and optical modules that mount in either an outdoor cabinet or an
indoor mounting shelf. Control and monitoring functions are provided by the Digivance
Element Management System (EMS). In addition, various accessory items including a back-up
battery for the RU, a passive Wavelength Division Multiplexer (WDM) system, and an active
Coarse Wavelength Division Multiplexer (CWDM) system are available as accessories.
