Chapter 1: Purpose and Planning
Introduction
to Chapter 1
Chapter 1 is aimed at management and planning staff to
enable them to assess the suitability and logistic requirements
of the µLink Digital Radio, hereafter referred to as the µLink.
µµLink
Product
Family
The µLink design philosophy was to produce a range of
products, with the data rate dependent purely on the Indoor
Unit (IU) and the frequency band dependent purely on the
Outdoor Unit (OU). Thus resulting in a common IU that can
operate with different frequency OUs, or alternatively, an OU
that remains unchanged while the data rate is altered or
upgraded. This manual covers the OU with integral 18dBi
antenna (EHC,THC referred to as -C), and the OU with N-
Type connector for use with a separate antenna (EHD, THD
referred to as –D).
Role and
Purpose
The µLink operates in the 2.4 GHz ISM frequency band. It
provides a full duplex, point-to-point, digital radio link
supporting user data rates up to 2048 kbit/s. It is used to
transport digital data between two or more sites. Whether the
digital information is voice, telephony, cellular, data or video
as required by various applications, the µLink can be deployed
in urban and rural networks as an interconnect solution.
Typical applications for the system include:
• Telecommunications companies, cellular operators and
private carriers using low cost spread spectrum E1/T1
links to substitute for conventional copper or licences band
microwave links
• Providing last mile leg in urban areas where frequency
bands are congested
• Rural communications
• Corporate Networks
