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  • Design standards are outdated, so it is essential to understand the limitations of the formulas and design rules coded into planning software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.

Managing Director, TMC Global
Trevor Manning has had the rare opportunity to see all the facets of designing and operating a microwave radio network. Having worked for both operators and suppliers, in a career spanning 30 years, he has also recently helped to design and build the world’s longest high capacity Ethernet link (>200km). He understands both the technical and commercial challenges to designing, building and operating networks.

    What previous attendees had to say about their experience

    "Enjoyed the delivery and the content. I'd seen the move away from microwave to fibre several years ago and now have a much better understanding of why microwave has its place and should be embraced."

    "Great structure.. the 2 hour format supports knowledge retention as opposed to day long courses."

    "I really enjoyed this course, Trevor is good at sharing his knowledge and experience of microwave in a manner that is helpful and easy to follow."

    "Extremely satisfied. A great bridge between very dry & often difficult to understand theory and real world examples."

    "Very happy overall, learnt some new principles and reinforced others. Thanks Trevor, great work!"

    "I found the sessions both enjoyable and educational. I now have a much better understanding of Microwave."
