ADC Wireless Overview

Digivance NXD and CXD

The Digivance NXD and CXD are fully Digital Distributed Antenna Systems (D-DAS) designed to

pecifically meet a service provider's current network needs and provide a fully flexible path to future

network migration. The NXD and CXD improve wireless networks by extending seamless wireless

coverage from existing cell sites to hard-to-reach areas, or distributing capacity from centralized radio

uites. The NXD is optimized for neutral host deployments.

NXD and CXD Features:

•

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

multiple point-to-point optical RF transport links

• 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)

NXD and CXD Applications Include:

• Wide area and medium range urban and suburban microcells

• Capacity and coverage underlay to existing 2G and 3G sites

• Multi-frequency, multi-operator deployments

• Campus environments and business parks

• Stadium and convention centers
