Research on electromagnetic radiation from wireless baby monitors, typically operating at DECT or WiFi frequencies.
Baby monitors have become essential tools for modern parents, providing peace of mind by letting you keep tabs on your sleeping child from another room. Most digital baby monitors operate using radiofrequency (RF) electromagnetic fields in the 1.9 to 2.4 GHz range - the same frequencies used by cell phones and WiFi routers.
