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.

RF Safe argues for a transition from microwave-based wireless (cellular/Wi‑Fi/Bluetooth) to light-based communications (e.g., Li‑Fi) to reduce indoor RF exposure. The piece claims chronic, low-level RF exposure may pose health risks beyond heating and calls for a precautionary approach, while also criticizing U.S. legal and regulatory frameworks it says limit local control and rely on older, heat-focused assumptions.
