Point-to-Point Radio Link Design


A set of Courses with Video Lessons, Complementary (pdf) material, Design Examples and Final Test, covering the main topics, from Free Space Propagation and Basic Radio Link Equation, to Path Analysis, Obstructions, Multipath Fading and Rain Attenuation. 

The motivation of this Training Program is to present fundamental phenomena in Electromagnetic Wave Propagation as well as Engineering Rules and Guidelines, as a useful background in the design of Point-to-Point Radio Links.

Following the Courses, you'll get a basic understanding of Radiowave propagation, moving then to applications in Radio Link Design, with the introduction of the most popular models for path obstruction, rain attenuation, multipath etc.  This allows a critical analysis of model options and of computed results.

Finally, at the end of each Course, a design example is presented, using the HERALD Sw, to show a practical application of the previous lesson.
