Chapter 1: Purpose and Planning
lntroduction to Chapter I is aimed at management and planning staff
Chapter 1 to enable them to assess the suitability and logistic
requirements of the uLink Digital Radio, hereafter
referred to as the uLink.
uLink Product The uLink design philosophy was to produce a range of
Family products, with the data rate dependent purely on the
indoor Unit (lU) and the frequency band dependent
purely on the Outdoor Unit (OU). Thus resulting in a
common lU that can operate with different frequency
OUs, or alternatively, an OU that remains unchanged
while the data rate is altered or upgraded.
Role and The uLink operates in the 2.4 GHz ISM frequency
Purpose 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 uLink can be deployed in
urban and rural networks as an interconnect solution,
Typical applications for the system include:
0 Telecommunioations companies, cellular operators
and private carriers using low cost spread spectrum
El/Tl 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

System Description C
System
Overview
A pLink digital radio relay link (URL) consists ofat
least one complementary pair of uLink stations that may
be extended over longer distances by linking further
station pairs in a multiple hop configuration A single
uLink station comprises an Indoor Unit (Figure I), an
Outdoor Unit and Antenna (Figure 2) The Indoor Unit
(IU) and Outdoor Unit (OU) are interconnected by a
custom cablei Figure 3 is a block diagram of an uLink
DRL.
Features The uLink offers die following key features:
0 T1 and El payload data interface optionsi
- IU is independent of OU frequency band and the C
OU is independent of IU data interfaces.
- Network management features, including remote
performance monitoring and configurability,
SNMP access to uLink via an SNMP agent will be
included in future upgrade products.
0 The equipment is compact and versatile, enabling
fast deployment.
- The system offers high data link reliability.
- Maintenance requirements are minimal.
0 The system provides built-in—diagnostic and test
features.
- Co-locate two (2) antennas on a single mast.

Site Evaluation
When planning a site for a digital radio relay link, it is
ofthe utmost importance that you take the operational
environment of the proposed site into account.
The combined effect of atmospheric environmental
factors such as rain and lightning, atmospheric
attenuation, signal path obstruction, propagation fading,
air temperature gradients, ice build-up, wind and solar
radiation can contribute towards reducing the level of
performance of the system (as measured in terms of its
capability to transfer data without error). In the higher
frequency bands, rainfall is the main attenuation
mechanism which limits error performance. Ice and
snow will obviously have a similar effect. Severely cold,
and excessively warm climatic conditions outside the
scope of the operating temperature range can affect the
function of the system, especially the outdoor equipment
(see Environmental Characteristics on page 18 of this
manual),
Also, if masts are not sufficiently rigid, very strong
winds can affect the antenna beam alignment and
outdoor equipment reliability due to wind force build-
up and/or vibration in the mast mounted equipment.
Non-atmospheric environmental factors such as the
electromagnetic interference due to the presence of
other antennas, path clutter and terrain topography can
also have a detrimental effect on system performance
and should be carefully assessed before and during
installation.
