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  • Design standards are outdated, so it is essential to understand the limitations of the formulas and design rules coded into planning software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 started his career as a specialist design engineer and over a career spanning 30 years, he held various senior management positions up to board level. He runs a training and consultancy business aimed at helping technical people transition from technical expert to manager and continues to offer training in his speciality field of microwave radio planning. He has written several books including “Help! What’s the secret to leading engineers?”, “Help! I need to master critical conversations” and “Microwave Radio Handy Reference Guide.” He is also the author of the best-selling classic Artech House book “Microwave Radio Transmission Design Guide”, which has sold thousands of copies worldwide and regarded as the de-facto reference book for propagation issues and radio link design.
