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 wireless coverage from existing cell sites to hard-to-reach areas or distributing capacity from centralized radio suites The Digivance family offers flexible, scalable solutions to fit various applications from a single building to a campus to a dense urban center
Features:
Flexible architecture enables macro network coverage to be distributed over individual or multiple point-to-point optical RF transport links:
• All-digital transport enables transition to optional capabilities such as free space optics links and coarse wavelength division multiplexing (CWDM)
• Digital RF transport is transparent to air modulation standards; e.g., iDEN®, GSM, CDMA, W-CDMA, 1xEV-DO
• Remote alarm monitoring from the network operations center (NOC) reduces
troubleshooting time
• SNMP support
• Local alarm networking of multiple systems for monitoring and control
• Tri-band solutions within a dual cabinet, supports future band upgrade

Trang 2Overview
With the increasing popularity and reliance on
wireless devices, subscribers expect to have
coverage at any time in any place they may
be This requires service providers to increase
capacity, which is typically done by adding new
cell sites However, with city centers becoming
more congested and local government zoning
regulations becoming 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 other areas that require
coverage
Application
The LRCS is the only long-range RF distribution
solution to offer a fully digital platform By using
patented 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 Digital RF transport allows the
signals to be replicated at full dynamic range,
independent of the fiber length, which improves
data throughput As advanced, high data rate
broadband services are rolled out, networks with
a LRCS backbone will be ready
ADC’s digital RF transport technology
accommodates enhancements, such as free
space optical laser links instead of physical fiber
connections for even faster deployment and
CWDM capabilities The CWDM option allows
multiple transmit and receive paths over a single fiber cable, potentially reducing annual fiber lease costs Free space optical laser links and millimeter wave solutions overcome fiber availability issues The LRCS offers a flexible architecture to distribute wireless capacity Its versatility and small size allow service providers to quickly deploy networks in areas where zoning restrictions often hinder installation of base stations Centralization
of base station capacity can also be realized using LRCS This allows service providers to further benefit by reducing capital expenditures and annual operating costs
System Description
The LRCS transports digitalized RF signals to difficult coverage areas such as congested city center locations, tunnels and canyons 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 enhanced base transceiver station (EBTS) site or co-located with other Host Units at a centralized base station radio (BR) suite The RF signal is transported digitally over fiber optic cable connecting the Host Unit to a Remote Unit The Digivance LRCS Remote Unit is positioned at the area requiring coverage and interfaces with an antenna to distribute the RF signal The distance between the LRCS Host Unit and Remote Unit
is limited mainly by time delay requirements
of system modulation standards (iDEN®, GSM, CDMA, W-CDMA, 1xEV-DO, etc.), which is typically several kilometers

Host Unit
The rack-mountable LRCS Host Unit is typically
located at an EBTS or a facility building housing
a suite of EBTSs 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 EBTS site Host Units can be daisy-chained
together to allow monitoring and control of
multiple links from a single user interface
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
• System mode (active/standby)
• Indicate faulty unit
• 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 typically in 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 signals 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 software, the LRCS Remote Unit also features front panel alarm reporting LEDs on the front panel of the Remote Unit will change color depending on the status
of the unit LED displays provide information regarding the following items:
• Power
• System mode (active/standby)
• Indicate faulty unit
• RF conditions
• Power amplifier fault
• Antenna fault system (VSWR) 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
Trang 4Alarm and Management System
ADC's Digivance EMS provides operational
and maintenance capability for the
LRCS The DigivanceEMS consists of a
personal computer (PC) using a Windows®
operating system, ADC furnished
Java-based software package; an ASCII Java-based
RS-232 capable terminal, and RS-232
cables
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
and software turnkey solution to element
management, as well as a software solution,
where operators utilize their existing element
management network
Host Site Capabilities
The EMS performs the following functions at the
host site:
• Provides real-time information regarding faults
• Displays various system level values (voltages,
RF, power, etc.)
• Records and generates history reports
with time and date stamps
• Adjusts performance related parameters
of the Host Unit and Remote Unit
• Permits placement of Host Unit and
Remote Unit into standby mode
• Allows download of new software
versions to the Host Unit and Remote
Units
Off-Site Capabilities
The EMS performs the following functions at off-site locations such as the NOC:
• Provides real-time information regarding faults
• Displays various system level values (voltages,
RF, power, etc.)
• Adjusts performance-related parameters of the Host Unit and Remote Unit
• Permits placement of Host Unit and Remote Unit into standby mode
The EMS provides real-time data to the operator
at the NOC through an ASCII-based, RS-232-capable terminal The ASCII terminal at the NOC communicates to the PC at the host site through
an RS-232 port
In addition, the operator has the ability to remotely access the EMS over Ethernet, RS-232 to Ethernet connection
