Research on electromagnetic radiation from cellular base stations, including 5G millimeter wave and sub-6 GHz deployments.
Cell towers and 5G infrastructure have become the invisible backbone of our connected world, but they're also one of the most significant sources of radiofrequency (RF) electromagnetic fields in our environment. These towers emit RF radiation across a broad spectrum, from 600 MHz to 39 GHz, with the newer 5G networks operating at both traditional frequencies and much higher millimeter wave bands. What makes this exposure particularly concerning is its involuntary and continuous nature.
