Research on environmental EMF sources - cell towers, 5G small cells, power lines, and smart meters.
## Outdoor / Infrastructure EMF Sources When you step outside your home, you enter an environment where electromagnetic fields come from sources beyond your direct control. Cell towers broadcasting 24/7, power lines carrying electricity to neighborhoods, smart meters collecting usage data, and increasingly, 5G small cells mounted on streetlights and utility poles. These infrastructure sources share a common characteristic: they're part of the built environment around us, installed and operated by utilities and telecommunications companies to serve entire communities.
