2.1 About This Manual
This manual is written for those who are involved in the installation and use of the
MDS FOUR.9 Series or MDS SIX.4 Series Digital Radio System, including installation
technicians, site evaluators, project managers, and network engineers. The transceivers are
comprised of a Software Defined Indoor Unit
TM
(SDIDU
TM
) and outdoor unit (ODU). The SDIDU
TM
is a product and trademark of CarrierComm.
This manual assumes the reader has a basic understanding of how to install hardware, use
Windows
based software, and operate test equipment. For the purposes of this manual, the
radios are referred to as the “Digital Radio Series” except where it is necessary to make a
distinction between the models covered or their operating frequency ranges.
2.2 Introduction
The Microwave Data Systems family of digital radios provides high capacity transmission,
flexibility, features, and convenience for wireless communications networks. These radios
represent a new microwave architecture that is designed to address universal applications for
both PDH and SDH platforms. This advanced technology platform provides the flexibility
customers need for their current and future network requirements.
The radio family is based on a common platform used to support a wide range of network
interfaces and configurations. It supports links for 16 x E1/T1, 100BaseTX Ethernet, and DS-
3/E-3/STS-1 (optional, consult factory for availability). 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. The radio family 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 MDS FOUR.9 Series
digital radio family operates in the FCC Public Safety Band of 4.940 to
4.990 GHz, which is generically referred to as the “4.9 GHz band.” It supports three types of user
data payload connectivity as follows:
•
100Base-TX intelligent bridging between two locations without the delay and expense of
installing cable or traditional microwave.
•
Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide
LAN connectivity and offer performance trade-offs between operational bandwidths, data
rates, and distance.
