Dual-Band 800/1900 MHz Systems
Coverage and Customer Retention
ADC, a leading solution provider for distributing and enhancing wireless capacity and coverage, offers the Digivance® Long-Range Coverage Solution (LRCS) The LRCS improves wireless
networks by extending seamless wireless coverage from existing cell sites to hard-to-reach areas or distributing capacity from centralized radio suites As part of the Digivance family of digital radio frequency (RF) transport solutions, LRCS is fully compatible with ADC’s Digivance Indoor Coverage Solution (ICS) The Digivance family offers flexible, scalable solutions to fit various applications from
a single building to a campus to a large city center area and beyond
The LRCS provides a platform for transporting and distributing both 800 and 1900 MHz wireless capacity from base stations to remote sites such as dense urban areas, canyons, tunnels, highways and large open facilities It allows radio capacity to be centralized in base station hotels, which can
be inexpensively located up to several miles away from the desired area, making more effective use
of capital expenditure and reducing annual operating costs
The dual-link 800/1900 MHz system affords service providers the flexibility to either overlay a 1900 MHz network or to grow an existing 800 MHz network with 1900 MHz deployment capability when needed The LRCS also enables service providers to add radios to meet ever growing capacity needs without any upgrade to the Digivance system
Features:
• Flexible architecture enables macro network
coverage to be distributed over individual or
multiple point-to-point optical RF transport
links
• Digital platform enables transition to new
capabilities such as free space optics links
and coarse wavelength division multiplexing
(CWDM)
• Digital RF transport is virtually transparent
to air modulation standards; e.g., CDMA,
iDEN®, GSM, TDMA, 1xRTT, 1xEU-DO, etc
• Remote alarm monitoring from the network operations center (NOC) reduces troubleshooting time
• Local alarm networking of multiple systems for monitoring and control
• Dual-link cabinet services both 800 and
1900 MHz networks in one outdoor enclosure
• 800 or 1900 MHz electronics can be deployed separately, allowing a pay-as-you-grow approach to network overlays Single-Band Cabinet LRCS Dual-Band Cabinet LRCS

Overview
With the increasing popularity of wireless devices,
subscribers expect to have coverage at any time,
in any place This requires service providers to
increase capacity and coverage, which is typically
done by adding new cell sites However, with
city center areas becoming more congested and
local government zoning regulations becoming
increasingly more stringent, obtaining permits for
new wireless cell sites is becoming increasingly
more difficult Extending service to these
hard-to-reach areas can be quite challenging ADC’s
LRCS is a cost-effective solution for extending or
distributing capacity from base stations to areas
that require coverage
Application
The LRCS is the only long-range RF distribution
solution to offer a fully digital platform Using
patented digital RF transport technology, the
LRCS digitizes the entire designated RF band,
digitally transports it over fiber, and reconstructs
the signal at full bandwidth, regardless of
modulation technology or data rate Digital
RF transport allows the signal to be replicated
at full dynamic range, regardless of the fiber
length, which increases the capability for
data throughput As advanced high-data rate
broadband services are rolled out, networks with
a LRCS backbone will be ready
The LRCS offers a flexible architecture to
distribute wireless capacity Its versatility and small
size allow service providers to quickly deploy
networks in dense urban areas, where zoning
restrictions often hinder installation of base
stations
ADC offers a single- and dual-band system, which
can be deployed with either 800 or 1900 MHz
electronics When deploying a dual-band system,
the other frequency can be deployed when
needed, thus allowing service providers to defer
capital expenditures until absolutely necessary
Centralization of base station
capacity can also be realized
using the LRCS, allowing service
providers to further benefit by
reducing capital expenditures
and annual operating costs
ADC's digital RF transport
technology accommodates
enhancements such, as
free space optical laser and
millimeter wave links instead of physical fiber connections and xWDM capabilities The xWDM option allows multiple transmit and receive paths over a single fiber cable, thus reducing annual fiber lease costs Free space optical laser links and millimeter wave solutions overcome fiber availability issues, as well as enable service providers a means to deploy wireless capacity in specific dense urban areas in just days
System Description
The LRCS optically transports digitized RF signals
to difficult coverage areas such as tunnels, canyons, large open structures such as stadiums, and congested city center locations One point-to-point RF transport link consists of a Host Unit, Remote Unit, and element management software
The LRCS Host Unit is typically rack-mounted
at the base transceiver station (BTS) site or collocated with other Host Units at a centralized radio suite The RF signal is transported digitally over two fiber optic cables that connect the Host Unit and Remote Units Optionally, the wave division-multiplexing (WDM) feature allows transport over a single fiber In either application, the link can also be configured for diversity operation, which requires an additional fiber The LRCS Remote Unit is positioned near the area requiring coverage (up to several kilometers from the Host Unit) and interfaces with an antenna to distribute the RF signal The distance between the LRCS Host Unit and Remote Unit is limited only
by time delay requirements of system modulation standards; i.e., iDEN®, GSM, CDMA, TDMA, 1xRTT, 1xEU-DO, etc
Multiple LRCS links can be readily deployed
as a system to distribute capacity and provide coverage to larger areas, such as an entire city center area The Digivance Element Manager System (EMS) provides operational and maintenance capabilities for up to 24 Digivance LRCS links

Host Unit
The rack-mountable LRCS Host Unit is typically
located at a remote BTS or a facility building
housing a suite of base stations near the area
requiring coverage On the forward path, the
Host Unit digitizes the designated RF band and
digitally transports it over singlemode fiber to the
Remote Unit On the reverse path, the Host Unit
receives the digitized signal and converts it to
RF The Host Unit also collects alarm information
from the Remote Unit
For system deployments, multiple links can be
networked together at the same BTS site Host
Units can be daisy-chained together to allow
monitoring and control of multiple links from
a single user interface Local monitoring and
control functions can be performed either directly
through the Host Unit or via a PC
Remote alarm monitoring and control of the
LRCS system can also be performed from an
off-site location or NOC Communications to
the NOC can be performed using a PC with a
standard physical layer protocol In addition to
sending alarm notifications to the EMS through
software, the LRCS Host Unit also features front
panel alarm reporting LEDs on the front panel
of the Host Unit will change color depending
on the status of the unit LED displays provide
information regarding the following items:
• Power
• Mode of system (active/standby)
• Indicate which unit is at fault
• RF conditions
Furthermore, alarm contact closures provide
major and minor alarms The Host Unit has two
alarm contacts that either report system operation
is seriously affected (major alarm) or system
operation is degraded (minor alarm) The Host
Unit operates on DC power
Remote Unit
The LRCS Remote Unit is an outdoor cabinet that is either pole-mounted or mounted on the side of a building On the forward path, the Remote Unit receives the digitized signal from the Host Unit and converts the signal back into
RF to be distributed via an externally mounted antenna On the reverse path, the Remote Unit digitizes the designated RF band and digitally transports it over singlemode fiber to the Host Unit In addition to sending alarm notifications
to the EMS through software, the LRCS Remote Unit also features front panel Remote Unit will change color depending on the status of the unit LED displays provide information regarding the following items:
• Power
• Mode of system (active/standby)
• Indicate which unit is at fault
• RF conditions
• Power amplifier fault
• Antenna fault Furthermore, alarm contact closures provide a final level of alarming capability at the Remote Unit Major and minor alarms are reported through these contact alarm closures The Remote Unit is powered by an AC source

The EMS can simultaneously monitor a
network of LRCS links by daisy-chaining
the alarm interfaces of up to 24 LRCS
Host Units Each of the Host Units
are connected through a controller
area network bus, and the PC can be
connected to any of the Host Units The
EMS has the ability to download software,
change parameters, and monitor alarms
The EMS provides three levels of alarms:
software reporting, LEDs and external contacts
Using a laptop PC, the EMS can also be used
for field test and troubleshooting at each
Remote Unit Additionally, off-site functionality
is accomplished through a terminal at the NOC
using a PC with a standard physical layer protocol
for the communications
ADC offers a complete EMS hardware
