This RF Safe commentary argues that wireless communications “took a wrong turn” by prioritizing radiofrequency/microwave transmission over light-based approaches, citing Alexander Graham Bell’s 1880 photophone as an alternative model. It suggests that widespread, continuous RF exposure in modern environments is undesirable and proposes light-based, room-scale wireless as more biologically compatible. The piece also speculates about a historical association between Heinrich Hertz’s close-range RF experiments and his later fatal illness, while acknowledging there is no controlled evidence proving causation.
