The Science Behind Invisible Technology
The science behind WiFi, cellular, satellites, broadband, microwaves, Bluetooth, and their real health effects — evidence-based, no fear, no hype.
Explore Topics
- WiFi — IEEE 802.11 evolution from 11 Mbps to 46 Gbps. OFDM, MIMO, beamforming, and why your router is 1,250x below safety limits.
- Cellular & 5G — 1G through 5G evolution. Sub-6 vs mmWave physics, SAR regulations, and the NTP rat study critique.
- Satellites — LEO, MEO, GEO orbits. Starlink constellation, GPS trilateration, and why satellite signals arrive at femtowatts.
- Broadband — Fiber optic, cable, DSL, satellite, powerline, ethernet — how your internet actually reaches you.
