The Science Behind Wireless Signals
To understand whether WiFi 6 poses any health risks, we must first look at the science behind wireless signals.
What is Electromagnetic Radiation?
WiFi uses radio waves, which are a form of electromagnetic radiation (EMR). This type of radiation exists in a range of frequencies. For context:
| Type of Radiation | Frequency Range |
|---|---|
| Radio Waves | 3 kHz to 300 GHz |
| Visible Light | 430 THz to 750 THz |
| X-Rays | 30 PHz to 30 EHz |
WiFi 6 primarily operates at 2.4 GHz and 5 GHz, which are significantly lower frequencies than harmful radiation types like X-rays or gamma rays.
Non-Ionizing Radiation and Its Safety
Electromagnetic radiation is divided into two primary categories:
- Ionizing Radiation – Includes X-rays and gamma rays, which have enough energy to remove tightly bound electrons from atoms, potentially causing cellular damage and increasing cancer risk.
- Non-Ionizing Radiation – Includes radio waves, microwaves, and visible light. This type lacks the energy to ionize atoms or molecules, making it largely considered safe at low intensities.
WiFi 6, like its predecessors, operates in the non-ionizing range. The World Health Organization (WHO) and other health authorities, including the Federal Communications Commission (FCC), have established guidelines on exposure limits to non-ionizing radiation, and current WiFi technology operates well within these safety parameters.
What Do Studies Say About WiFi and Health?
Research on the health implications of WiFi exposure has been ongoing for over two decades. While early studies raised concerns about various adverse effects, more comprehensive and recent research has generally concluded that:
Most Studies Find No Direct Link to Health Problems
