1.1 About This Manual
This manual is written for those who are involved in the “hands-on” installation of the WNI Global
Digital Radio, such as installation technicians, site evaluators, project managers, and network
engineers. It assumes the reader has a basic understanding of how to install hardware, use
Windows

based software, and operate test equipment.
1.2 Introduction
The Challenger L digital radios provide high capacity transmission, flexibility, features, and
convenience for wireless digital communications networks. The Challenger L series digital point-
to-point radios represent a new microwave architecture that is designed to address universal
applications for both PDH and SDH platforms. This advanced technology platform is designed to
provide the flexibility to customers for their current and future network needs.
The Challenger L series equipment is based upon a common platform to support a wide range of
network interfaces and configurations. It supports links for 16 x E1, E-3, 1/2 x 100BaseTX
Ethernet, and 1 x STM-1. The radio family is spectrum and data rate scalable, enabling service
providers or organizations to trade-off system gain with spectral efficiency and channel availability
for optimal network connectivity. Challenger L series digital radio enables network operators
(mobile and private), government and access service provides to offer a portfolio of secure,
scalable wireless applications for data, video, and Voice over IP (VoIP).
The Challenger L digital radio family is composed of a Challenger L Indoor Unit and Outdoor
Unit (ODU). The Challenger L IDU is designed to be frequency independent, and the ODU is
designed to be capacity independent. The Challenger L IDU allows selection for multiple
capacity options, modulation types, radio frequency channels and transmit output power
levels to accommodate and adhere to world-wide regulatory and spectral efficiency
requirements. The companion ODU, mounted outdoors, can support frequency bands from
7 to 38 GHz.
The Challenger L IDU supports 1+0 and 1+1 protection and ring architectures in a single 1
RU chassis. The modem and power supply functions are supported using easily replacable
plug-in modules. An additional feature of the Challenger L IDU is provision for a second
plug-in modem/IF module to provide repeater or east/west network configurations.
The Challenger L Digital Radio includes integrated Operations, Administration, Maintenance, and
Provisioning (OAM&P) functionality and design features enabling simple commissioning when the
radio network is initially set up in the field at the customer’s premises. Furthermore, a highlight of
Challenger L radio products is scalability and the capability to support a ring-type architecture.
