Microwave Radio Masterclass

About this seminar

  • Authoritative – dispels industry myths
  • Practical – tutorial examples done using excel-based Microwave calculator
  • Real-world – real-world insights and experiences shared based on legacy and current network experiences
  • In-depth theory – theoretical concepts and insights explained in detail linked to propagation research and field experiences

Why a seminar on a mature technology?

  • Microwave technology is growing, with exciting new developments in mmWave and TeraHertz bands
  • Design standards are outdated, so it is essential to understand the limitations of the formulas and design rules coded into planning software
  • Many myths abound on the internet, and even in mainstream white papers, that are blatantly wrong
  • To apply the new and exciting concepts introduced in modern microwave equipment, a solid foundation in both analogue and digital microwave theory is essential

If you want an up-to-date, authoritative overview of microwave radio that dispels the many myths that have become mainstream in the industry, then this virtual seminar is for you.
