Pathloss . V Workshop

5 days instructor led course with case studies..
Course Overview

The offered course is a 5 days intensive Pathloss V link planning tool, which allowed students to develop an intuitive understanding of both the theoretical concepts and their practical application when planning links with Pathloss link planning tool. The Pathloss V program is a comprehensive path design tool for radio links operating in the frequency range from 30 MHZ to 100 GHz. The program is organized into several path design modules.

Key Benefits

Participants of this course will be able to plan microwave point-to-point links using software planning tool Pathloss 5.0, including ability to analyse data from path surveys, create respective profile data and decide upon antenna heights, calculate Performance and Availability percentages of the link and optimise them with respect to the ITU-R objectives as well as cost-effectiveness.

Course Objectives

As a minimum course participants will be able to:

  • Understand General Program Operation and detailed functions of all the Pathloss software Modules.

  • Understand the meanings of different types of terrain data types, Geographic defaults, Datum and Ellipsoids, and their selection criteria

  • Basic procedures to create terrain profiles from primary and secondary terrain data files.

  • Carry out antenna center line calculations and determine the minimum antenna heights which will result in acceptable diffraction loss at the lowest expected value of K with Pathloss diffraction Module

  • Determine the optimal space diversity antenna spacing to avoid simultaneous signal nulls (Reflection Module)

  • Generate Link Budgets and understand the significance of multipath propagation reliability and analyze microwave links

  • Understand and apply fade probability models and how to use the in Pathloss link predictions

  • Calculate diffraction loss of a radio wave propagating over irregular terrain using a number of diffraction models supported by Pathloss program 

  • Conduct Interference calculations down to the composite threshold degradation of the victim receivers due to multiple interferers.
