FlexWave™ – ADC’s Next Generation of Wireless Solutions
for Improving Wireless Capacity, Coverage, Flexibility
and Customer Retention
ADC’s FlexWave™ Prism is the most flexible, scalable and complete solution for addressing coverage
and capacity needs for current and emerging wireless networks. The Prism improves wireless network
coverage and capacity by extending services from existing cell sites, to hard-to-reach areas by
distributing coverage from a centralized radio suite.
Utilizing a centralized distributed architecture, service providers are able to recognize significant
CAPEX/OPEX savings through a shared Base Station Hotel (multiple BTS co-located together), as well as
a shared Remote Radio Transceiver approach. The Prism’s flexibility and scalability offers service providers
an optimal solution for multiple applications such as; dense urban centers, dense suburban areas,
campuses, enterprise buildings, subways and tunnels. The Prism’s distributed architecture and small form
factor allows service providers to cost-effectively increase coverage and capacity in these hard-to-reach
areas.

Overview
With the increasing popularity and reliance on wireless voice and data services, subscribers expect to
have coverage at anytime, anywhere. In addition to increased wireless device usage, wireless service
providers implementing 3G technologies have recognized a reduction in coverage patterns within
existing coverage footprints, opening coverage “holes” within the network. To resolve this issue, it
requires service providers to extend coverage and/or increase capacity within the non-coverage areas.
This has been traditionally accomplished by adding new macro cell towers; however, with city centers
becoming more congested and local government zoning regulations becoming more stringent,
obtaining permits for new macro cell sites is becoming increasingly difficult. The Prism offers service
providers a flexible, small form factor solution to extend coverage and capacity where needed, as well as
support for the increasing number of protocols and frequencies available today and in the future.

Application
The FlexWave Prism uses patented digital-over-fiber technology to distribute RF to desired locations. The
Prism digitizes the entire designated RF band and digitally transports it over dark fiber or millimeter wave
links and reconstructs the signal at full bandwidth, regardless of modulation technology, at the remote
location. ADC’s digital RF transport allows RF signals to be replicated at full dynamic range, independent of
the link length, for improved data throughput. As service providers migrate to 3G and 4G networks, high-
data rate broadband services, networks utilizing a Prism backbone will be ready.
The Prism offers a flexible architecture to distribute wireless coverage and capacity. Its versatility and small
form factor allow service providers to quickly deploy networks in areas where zoning restrictions often
hinder installation of traditional macro cell towers and base stations.
Centralization of base station capacity can also be realized using the FlexWave Prism. This allows service
providers to further benefit by reducing capital expenditures and annual operating costs.

Host Unit
Host Unit
The rack-mountable FlexWave Prism Host Unit is typically located at a Base Station or a facility housing
a suite of Base Stations. On the forward path, the Host Unit receives the RF signals from the BTS and
digitizes the designated RF bands and digitally transports them over single mode fiber or a millimeter
wave link to the Remote Units. On the reverse path, the Host Unit receives the digitized RF signals from
the Remote Unit and converts them back to RF for the BTS.
The Prism Host Unit is completely modular in design. Digital/Analog Radio Transceiver (DARTS) are hot
swappable providing easy upgrades to addtional bands without interrupting existing service.
FlexWave
10/08 • 106969AE
The Prism Host Unit supports up to eight DART cards (supporting up to eight Remote Units) and
is capable of simulcasting signals up to as many as eight Remote Units.
The Host Unit utilizes an embedded element management system for system configuration and network
monitoring. The embedded EMS collects alarm information from both the Host and Remote Units. For
multiple link deployments, multiple Host Units can be networked together at the same BTS site.
In addition to sending alarm notifications to the Element Management System (EMS) through software,
the Prism 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 unit fault condition•

Remote Units
The Prism Remote Units utilize a modular design, which supports up to four bands. Each Remote allows
for future upgrades and easy field access.
Typical mounting options for the Remote Unit include: pole-mount, inside pole-mount, wall-mount, and
sub-terrain vault-mount.
The electronics enclosure of the Prism Remote Unit is fully sealed IP-65 rated, which minimizes
maintenance and is ideal for harsh environments. Fiber, antenna, and power input/output connectors
are all sealed for maximum protection.
On the forward path, the Remote Unit receives the digitized spectrum from the Host Unit and converts
the spectrum back into RF to be distributed via an externally mounted antenna system. On the reverse
path, the Remote Unit digitizes the designated RF spectrum and digitally transports it over single-mode
fiber or MMW to the Host Unit.
In addition to sending alarm notifications to the EMS software, the Prism Remote Unit also features LED
alarm reporting. An LED on the bottom of the Remote Unit will illuminate upon a fault condition.

Alarm and Management System
The FlexWave Prism utilizes an embedded network management for system configuration and network
monitoring. The Element Management System (EMS) utilizes a web based interface or SNMP protocol
for easy accesses to the system.
The EMS provides operational and maintenance capabilities for the Prism system (Host and Remote). The
EMS can be used to set up and monitor status of any Host and any associated Remote Units. The EMS
has the ability to configure the system, view status and parameter settings, download software, change
parameters and monitor system performance and alarms
Access and troubleshooting can also be accomplished on-site at either the Host Unit and/or the Remote
Unit by utilizing a craft interface. Thus, allowing technicians the ability to plug-in a laptop and access all
associated units connected to it.
