NXD

Digital Distributed RF

ADC’s Digital Advantage

ADC, a leading solution provider for distributing and enhancing wireless capacity and coverage,

now offers the Digivance NXD. The Digivance NXD is a fully Digital Distributed Antenna System

(D-DAS) designed to specifically meet a service provider’s current network needs and provide a fully

flexible path to future network migration. The Digivance product improves wireless networks by

extending seamless wireless coverage from existing cell sites to hard-to-reach areas, or distributing

capacity from centralized radio suites.

Digivance NXD is a member of ADC's family of digital radio frequency (RF) transport solutions that

include the Digivance CXD, the Digivance Long-Range Coverage Solution (LRCS), Digivance Street-

Level Coverage Solution (SCS), and the Digivance Indoor Coverage Solution (ICS). ADC leverages

its expertise in wireless technologies, as the industry leader in fully digital, multi-frequency digital

DAS network equipment, providing network operators with predictable and highly controllable RF

coverage and capacity solutions.

Features

• Flexible architecture enables macro network coverage to be distributed over individual or

multiple point-to-point optical RF transport links

• Optimized for neutral host operators, able to co-locate multiple operators at a single location

• Digital RF transport is transparent to air modulation standards; e.g., GSM, CDMA, etc.

• Individual modules for 800, 850, and 1900 MHz frequency blocks

• Field upgradeable in single block increments

• Digital simulcasting, system capable of digital switching of radio sectors

• Fully digital transport for precise system settings and management

• Open standard SNMP-based interface, remote control and alarming using commercial Network

Management Systems (NMS)

• Local alarming and control using embedded Element Management System (EMS)

Digivance® NXD Digivance NXD Hub Digivance NXD RAN The Digivance NXD hub is typically located at a remote BTS or a facility building housing a suite of base stations near the area requiring coverage. On the forward path, the system digitizes the designated RF band, electrically multiplexes signals with other RF bands into a single digital link, and transports it over singlemode fiber to the remote unit. The system can also digitally simulcast multiple remotes from a single base station sector.
