PRISM SYSTEM OVERVIEW
ADC’s FlexWave
®
Prism is a compact radio head utilized for precision and macro
gap coverage, which supports up to four frequency bands, while delivering
high-performance coverage with end-to-end management. FlexWave Prism is
ideal for enhancing outdoor and indoor coverage in urban, suburban, canyons,
tunnels, campuses, stadiums and other public venues.
A Prism system offers the following features:
• ADC’s patented RF-over-fiber transport eliminates installation-dependent gain
or fiber length adjustments
• Improved manageability for installation and upgrades
• Smaller size to ease placement and zoning approvals
• 4G readiness with Four Band remote, which is ideal for incorporating 2G and
3G services with needs of 4G technologies such as LTE
• The unique capability to support digital RF as well as baseband compatibility
into a single fiber pair and remote radiating point
• Support for millimeter wave backhaul
• With its unique use of wideband digital RF transport, FlexWave Prism delivers
reliable and consistent performance in all environments. Signals are not
affected by reflection, dispersion, or frequency attenuation over fiber.
FlexWave Prism delivers a reliable signal at every remote location.
The ADC FlexWave Prism family of products is a Distributed Antenna System
(DAS) that provides ADC’s patented technology—bidirectional transport of
digitized RF spectrum over fiber. The high-speed digitalization of a wideband
portion of spectrum allows for transport of RF signals over extended distances,
without the RF degradation that normally results when analog systems are
impacted by optical effects. The basic function of the FlexWave Prism platform is
to transport via fiber optic cable RF signals from a Base Transceiver Station (BTS)
to an antenna interface allowing communication to a mobile device. Multiple BTS
communication paths are allowed over a single Prism system.
A very basic Prism system consists of a Host Unit (Host) and a Prism Remote Unit
(PRU).
• The Host is a three rack unit high chassis with multiple cards that mounts in a
standard equipment rack.
• The PRU consists of multiple electronic and optical modules mounted in an
outdoor enclosure.
On an optional basis, the Prism system supports reverse path diversity. In
addition, various accessory items such as a passive Wavelength Division
Multiplexer (WDM) system and a Coarse Wavelength Division Multiplexer (CWDM)
system are available as accessories.
Control and monitoring functions are provided by the FlexWave Element
Management System (EMS).
