The Radiation Safety of 5G Wi-Fi: Reassuring or Russian Roulette?

To the Editor: The impending rollout of fifth-generation (5G) Wi-Fi in mobile phones, augmenting the current fourth-generation (4G) technology toward making global interconnectivity between devices a reality, has been touted as a significant improvement of speed compared to current and previous wireless signaling (1). Less well explored are the potential consequences associated with this need for speed: namely, the substantial increase in biologic exposure to radiofrequency electromagnetic fields from the 1900-2100 MHz associated with 4G to the 3500 MHz estimated median bandwidth of 5G (2).
