Overview

With increased popularity and reliance on wireless

devices, subscribers expect to have service 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 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 often requires overcoming major challenges

The SCS is a cost-effective solution for extending

or distributing capacity from base stations to

other areas that require coverage

Application

Digivance is the only all-digital DAS available

today By using patented technology, the SCS

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 become available, networks

with ADC’s SCS technology will be ready

ADC’s digital RF transport technology

accommodates enhancements such as free space

optical laser links, millimeter wave links and

xWDM capabilities The xWDM 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 SCS offers all

the benefits of digital

technology in a

maintenance-free,

compact Remote Unit Its

versatility and small size

allow service providers to

quickly deploy networks in

challenging service areas

Centralization of base

station capacity can also

be realized using the SCS

This allows service providers to further benefit

by reducing capital expenditures and annual operating costs Base station radio capacity may

be simulcast to multiple remotes by using RF splitting and combining capabilities The SCS is a cost effective way to solve coverage and capacity problems without assuming the capital expense and time it takes to deploy additional cell sites

System Description

The SCS optically transports digitized 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 and corresponding Remote Unit

The SCS Host Unit is typically rack-mounted

at the base transceiver station (BTS) site or collocated 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 to a SCS Remote Unit The SCS Remote Unit is positioned at the area requiring coverage and interfaces with an antenna to distribute the RF signal The distance between the SCS Host Unit and Remote Unit is typically limited only by time delay requirements

of system modulation standards (iDEN®, GSM, CDMA, W-CDMA, 1xEV-DO, and HSDPA, etc.), and can be as far as several kilometers With the product’s 25 dB optical budget, the SCS can be deployed in the most challenging fiber plants

Host Unit

The rack-mounted SCS Host Unit is typically

located at a BTS or a facility housing a suite of

BTSs On the forward path, the Host Unit digitizes

the designated RF band and digitally transports

it over singlemode fiber to the SCS 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

Remote alarm monitoring and control of the

SCS can be managed from an off-site location

or NOC Using a standard PC with a standard

physical layer protocol, communications can be

delivered to the NOC In addition to sending

alarm notifications to the Digivance EMS through

software, the SCS 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)

• Indication of 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 small-form-factor SCS Remote Unit minimizes visual pollution and offers multiple mounting options that easily blends into the environment Mounting options for the single- and dual-system remotes include inside pole-mount, pole-wrap, wall-mount, strand-mount and sub-terrain vault-mount capabilities The Remote Units can be mounted in a vertical or horizontal position in less than five minutes, are sealed NEMA 6/IP-67 rated enclosures that can be deployed in the harshest environments Fiber, antenna, and power input/ output connectors are all sealed for maximum protection

For installations in areas with significant solar load, ADC offers a solar shield shroud to protect the SCS

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 SCS Remote Unit also features LED alarm reporting An LED on the bottom

of the Remote Unit will illuminate upon a fault condition The LED will display information about the following:

• System mode (active/standby)

• Indication of faulty unit

• RF conditions

• Power amplifier fault

• Antenna fault system (VSWR)

Alarming and Management

ADC's Digivance® Element Management

System (EMS) provides operational and

maintenance capability for the SCS The

EMS consists of a personal computer (PC)

using a Windows® operating system, ADC

furnished Java-based software package;

an ASCII based RS-232 capable terminal,

and RS-232 cables

The EMS can simultaneously monitor a

network of SCS links by daisy-chaining

the alarm interfaces of up to 24 SCS

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 SCS

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:

• 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
