Point-to-Point Radio Link Design


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

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.

Course List :
