About WiFi Routers EMF

  • -Your WiFi router is the silent workhorse of modern connectivity, broadcasting radiofrequency (RF) electromagnetic fields 24 hours a day to keep your devices online.
  • -Operating primarily at 2.4 GHz and 5.8 GHz frequencies, these ubiquitous devices emit the same type of radiation as cell towers and cell phones, just at lower power levels.
  • -What makes routers particularly significant as an EMF source is their constant presence in our homes and offices, often positioned in central locations where we spend the most time.
