1 INTRODUCTION
This section provides basic description, application, and configuration information about the
Digivance single band 800 MHz Long-Range Coverage Solution (LRCS). Throughout this
publication, all items referenced as “accessory items” are not furnished with the basic product
and must be purchased separately.
2 SINGLE BAND SYSTEM OVERVIEW
The Digivance single band SMR 800 MHz LRCS is an RF signal transport system that provides
long-range RF coverage in areas where it is impractical to place a Base Transceiver Station
(BTS) at the antenna site. High real estate costs and community restrictions on tower and
equipment locations often make it difficult to install the BTS at the same location as the
antenna. The Digivance LRCS is designed to overcome equipment placement problems by
allowing base stations to be hubbed at a central location while placing remote antennas at
optimum locations with minimal real estate requirements. With the Digivance LRCS, RF
signals can be transported to one or more 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 Components
The basic components of a single band Digivance LRCS system and their functions are shown
in Figure 1-1. A single band LRCS system consists of the Host Unit (HU) and the Remote Unit
(RU). Control and monitoring functions are provided by the Digivance Element Management
System (EMS). On an optional basis, each HU and RU system may be ordered either with or
without reverse path diversity. In addition, various accessory items including a back-up battery
kit (for the RU), a Wave Division Multiplexer (WDM) module (for the HU and RU), network
cables (for connecting multiple HU’s together), and EMS cable (for connecting the EMS
computer to the HU) are available separately.
