Digivance®
Street-Level Coverage Solution (SCS)
ADC’s Digivance Street-Level Coverage
Solution (SCS) helps wireless service providers
improve capacity in dense urban areas where
restrictive zoning requirements prohibit
deployment of necessary network equipment.
This digital distributed antenna system (D-DAS)
utilizes patented RF transport-over-fiber
technology to distribute wireless service
between existing cell sites and SCS remote
antenna units. The low power, small-formfactor remote units offer an unobtrusive
design and multiple mounting options that
easily blend into the environment. The
maintenance-free design of the remote
antenna units makes the SCS ideal for
improving capacity in hard-to-access areas
such as tunnels, subways, and urban canyons.

• Supports 800 cellular, 800 SMR, 900 SMR,
and 1900 PCS
• Noiseless (no fans) remote is sealed NEMA
6/IP-67 rated enclosure with passive cooling

compact remote unit
• Remote units mount vertically or horizontally
– inside pole, pole wrap, wall mount, and
strand mount

Digivance® Street-Level Coverage Solution
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, which is typically done by adding new cell
sites. However, with city centers becoming more congested and local government zoning regulations
increasingly more stringent, obtaining permits for new wireless cell sites is becoming nearly impossible.
Extending service to these hard-to-reach areas often requires overcoming major challenges. The
Digivance Street-Level Coverage Solution (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 distributed antenna system (D-DAS) available today. By using patented
technology, the Digivance 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 Digivance SCS technology will be ready.
ADC’s digital RF transport technology is also conducive to 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 overcome fiber availability issues, as well as enable
service providers to deploy wireless capacity in specific dense urban areas in days.
Digivance 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 areas where zoning
restrictions often hinder installation of base stations. Centralization of base station capacity can also be
realized using Digivance SCS. This allows service providers to further benefit by reducing capital
expenditures and annual operating costs.
System Description
The Digivance SCS is an all-digital distributed antenna system (D-DAS) that optically transports RF signals
to difficult coverage areas such as congested city center locations, tunnels, and canyons. One point-topoint RF transport link consists of a host unit and corresponding remote unit. Base station radio
capacity may be simulcast to multiple remotes by using RF splitting and combining capabilities.
The Digivance SCS host unit is typically rack-mounted at the base transceiver station (BTS) site or colocated 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 remote SCS unit. The Digivance SCS remote unit
is positioned at the area requiring coverage and interfaces with an antenna to distribute the RF signal.
The distance between the Digivance SCS host unit and remote unit is typically limited by time delay
requirements of system modulation standards (iDEN®, GSM, CDMA, etc.), and can be as far as 40 miles
or more. With the product’s 25 dB optical budget, the SCS can be deployed in the most challenging
fiber plants.
Element Management System (EMS)
The Digivance EMS provides operational and maintenance capabilities for the SCS product. This EMS
can simultaneously monitor a network of Digivance SCS links by daisy-chaining the alarm interfaces of
up to 24 Digivance SCS host units. Each host unit is connected through a controller area network bus,
and the PC can be connected to any of the host units. The Digivance EMS has the ability to download
software, change parameters, and monitor alarms. It also provides three levels of alarms: software
reporting, LEDs, and external contacts.
In addition, off-site functionality is accomplished through a terminal at the NOC utilizing Digivance EMS
or Digivance - supported SNMP. Through StarGazer®, ADC’s SNMP manager, enhanced GUI, alarm
management and interfaces are provided.

Host Unit
The rack-mountable Digivance SCS host unit is typically located at a BTS or a facility housing a suite of
BTSes. On the forward path, the host unit digitizes the designated RF band and digitally transports it
over single mode fiber to the remote SCS 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 Digivance SCS system can also be managed from an offsite location or NOC. Using a 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 Digivance 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 low power, small-form-factor Digivance SCS remote unit offers an unobtrusive design and multiple
mounting options that easily blend into the environment. Mounting options for the single-band and
dual-band remotes include inside pole mount, pole wrap, wall mount, and strand mount. The units,
which 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.
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 single mode fiber to the
host unit.
In addition to sending alarm notifications to the Digivance EMS software, the Digivance 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:
• Indication of faulty unit
• RF conditions
• Power amplifier fault
• Antenna fault system (VSWR)
