Research on electromagnetic radiation from DECT cordless phones, which transmit continuously even when idle.
That cordless phone sitting in your kitchen or living room may seem like a harmless relic from the pre-smartphone era, but it's actually one of the most potent sources of radiofrequency (RF) radiation in your home. DECT phones (Digital Enhanced Cordless Telecommunications) operate at 1.9 GHz, continuously transmitting RF signals between the handset and base station even when you're not making calls.
