Microwave radio has been around for over 50 years so why would you spend 2 days in a master-class on this veteran technology? The challenge is that a lot has changed in microwave radio technology, as well as the regulatory framework, but nothing has changed in terms of the physics of the analogue signal over-the-air. With all the confusing often over-hyped claims from many microwave manufacturers, as well as the plethora of misinformation on the internet, it is easy to get confused between fact versus fiction.

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 seminar is for you. You will also get a free copy of the just-published ‘Microwave Radio Handy Reference Guide’.

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  • Design standards are outdated, so it is essential to understand the limitations of the formulas and design rules coded into planning software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

About the presenter
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 (>200 km).  He understands both the technical and commercial challenges to designing, building and operating networks.

His pragmatic approach to the subject will help unravel the mysteries of the many confusing standards, as well as simplify the complexities of radio design with its dependence on complex weather conditions, to equip you to know when, and how, to deploy microwave radio in current real-world networks.

Trevor Manning is the author of Microwave Radio Handy Reference Guide, and is also the author of the classic Artech House book Microwave Radio Transmission Design Guide (second edition).
