Research on EMF from home networking equipment - WiFi routers, mesh systems, and smart meters.
Your home network creates a unique EMF exposure environment that most of us never think about, yet it's where you spend the majority of your time. Unlike the isolated EMF sources you might encounter elsewhere, your home networking equipment operates continuously, creating what researchers call "chronic low-level exposure." WiFi routers typically emit radiofrequency radiation at power levels of 100 milliwatts to 1 watt, broadcasting their signals 24/7 throughout your living space.
