RCA’s 2018 Technical Symposium and Awards Banquet Was a Great Success!

For those that were able to make the Technical Symposium and the Awards Banquet, both were great events!  At the Technical Symposium 74 attendees watched 9 presentations.   The slide decks will be up on this Website in a few days.   Dr. Rappaport’s keynote was both excellent and moving on his life and career in wireless.  

Pictures from the Technical Symposium:

The 2018 Awards Banquet’s Keynote Speaker was Dr. Ted Rappaport.  Dr. Rappaport has over 100 U.S. or international patents issued or pending and has authored, co-authored, and co-edited over 200 papers and 20 books in the wireless field, including the classic Wireless Communications: Principles & Practice (translated into seven languages).  He is the David Lee/Ernst Weber Professor of Electrical and Computer Engineering at the NYU Tandon School of Engineering   He is a pioneer in RF propagation, wireless systems simulation, and 5G networks. His research has influenced international standards bodies for three decades.

Here’s an article from the EDN Network about Dr. Rappaport and his early involvement with amateur radio which led to his life’s passion for wireless.

We had speakers or panels on 5G Technology, 5G Market Rollout, FirstNet, the Internet of Things (IoT), the impact of the 2017 solar eclipse on propagation, the challenges of data on HF links, and the impact of the radio school at Harvard during WWI.  Click here for more information on the 2018 Technical Symposium including the slide decks and a link to the videos

 RCA at the Dayton Hamvention Youth Forum

Carole Perry’s annual Youth Forum is one of the most well attended events at the Dayton amateur radio festival.  Carole features a number of school-aged youth who have become interested in STEM (science, engineering, technology, and math) through their experiences with amateur radio.  This was the 31st Youth Forum hosted by Carole Perry and RCA!
