Course Objectives

Pathloss 5 program is a comprehensive path design tool for radio links operating in the frequency range from 30 MHz to 100 GHz. It is an advanced planning software to design microwave radio relay links and networks. Transmission engineers working on Microwave network planning uses this software tools to ensure a methodical and thorough approach to their task.

Covering a variety of topics ranging from software installation, upgrade to network design/operations, the objective of this training is to develop knowledge and skills of microwave link design using Pathloss 5 software.

After successful completion of this workshop, participants will be able to

  • Understand microwave transmission propagation theory along with the basic features of Microwave radio system.
  • Calculate Antenna heights as well as multipath and rain related performance using manual data and/or digital terrain models.
  • Analyze path diffractions and multipath reflections and its effects and choose suitable countermeasures.
  • Perform inter-system and intra-system interference calculations and ensure their frequency channels are free from harmful threshold degradations,
  • Generate Link Budgets and understand the significance of multipath propagation reliability to design a large scale Microwave network.
  • Calculate multiple parameters of the link and optimise them with respect to the ITU-R objectives as well as cost-effectiveness.
