February 8 - Should We Worry About 5G Towers?

Presented by Roopesh Ojha, Ph.D.

The fifth generation wireless technology for digital cellular networks, popularly known as 5G, is rapidly being deployed around the world. The leap in network speeds it will enable have several well-known benefits and, if the past is any guide, the most profound benefits haven't even been imagined yet. 5G uses radio frequencies that are higher than the radio frequencies in current use. In some quarters, concerns have been raised about putative health impacts of these radio waves. In this talk, Dr Ojha will take a look at 5G from the physics perspective as well as the statistics perspective and discuss where the balance of probabilities lies.

Dr. Ojha has worked for the Harvard Smithsonian Center for Astrophysics (including a year operating a telescope at the South Pole) in Cambridge, MA, the Australia Telescope National Facility in Sydney, and the United States Naval Observatory in Washington, DC. He currently works for the Fermi Gamma-ray Space telescope primarily studying the physics of active galactic nuclei - galaxies where the dominant source of energy is matter falling onto a central supermassive black hole. Dr Ojha is known for his ability to communicate science at any level, from highly specialized scientific meetings to elementary school students. He is a regular speaker at local schools, non-profit organizations, and STEM events.
