RF safety issues: why so controversial?
The dramatic increase in man-made radio frequency (RF) fields in the environment has led to public health concerns in many parts of the world. Specifically, questions have been raised on the safety of exposure to RF energy emitted from radar, television and radio broadcasting systems, microwave ovens, video display terminals, and most recently, mobile telephones and base stations, such as Wi-Fi, and 2 to 5 G. Wearable RF gadgets are prevailing. Wireless power transmission is a newer subject, which can involve high intensity exposures. The IEEE EMF database now has more than 7500 original, peer-reviewed papers useful for public health risk assessment of RF exposure. Even there has been 70 years of research, and WHO indicated that scientific knowledge in this area is now more extensive than for most chemicals and current evidence does not confirm the existence of any health consequences from exposure to low level electromagnetic fields, controversy on RF safety continues. Two international groups, IEEE and ICNIRP have been addressing this issue for decades. While the goal of both groups is to provide limits that protect against established or known adverse health effects, there are groups that advocate more stringent exposure limits based on possible biological effects, at limits that are impossible to implement without serious consequence. Both biological and engineering complexities make the validity of many studies questionable. Samples of RF biological effects studies will be shown. In this presentation, research, standards, regulation and risk communication concerning RF safety will be addressed.
Presenter: Dr. C-K Chou, IEEE International Committee on Electromagnetic Safety TC95 Chairman
Broadcast Radio Technology in the US – Where We Are and Where We Are Headed
It seems appropriate in 2020, the year of the 100th anniversary of radio, to offer a status report on US broadcast radio technology, where it is today and where it is headed. In this session Mr. Layer will provide an overview of current AM and FM-band broadcast technology, focusing in particular on hybrid (over-the-air plus internet) and digital radio services, and including some of the technical work being done within the National Radio Systems Committee (NRSC, a technical standards-setting body co-sponsored by the National Association of Broadcasters and the Consumer Technology Association). Following this, the focus will shift to a look ahead, at how over-the-air services are expected to evolve and at the growing influence of streaming audio services on broadcasting.

Future of Broadcast TV
Over the last 25 years Standards Developing Organisations (SDO) like ATSC or DVB have provided the necessary specification for the transition from analogue to digital TV. Analogue Switch Off has happened in many parts of the world. Now, with HD and UHD being specified as well, what will be the future roadmap for broadcast media technology and how can SDOs provide the technology for next generation broadcast?

Broadcasting's Bright Future
Presenter: Paul Shulins, President of Shulins' Solutions
The Broadcast landscape is changing rapidly, and today’s engineers are learning new skills as the technology evolves. There is more emphasis on data delivery today and we are constantly finding better ways to deliver content to our audiences. What does this mean for the young engineers embarking on a career in broadest engineering? During this webinar I will reflect on my career in broadcast engineering, sharing experiences and observations, helping us to recognize trends and react to them wisely. Using practical experience examples like facility consolidation, adopting new technology such as HD Radio and using tools for ratings metrics, I will review some of the innovations I have been a part of, the results of those advances, and how the career has been so rewarding. I will discuss why broadcasting is here to stay, and why I believe we have the most efficient way of distributing content. For anybody interested in Broadcast Engineering this discussion will be a positive experience. A question and answer period will follow the presentation
