Not the same technology. You're conflating 5 GHz band WiFi with 5G mobile technology that follows 4G LTE. The 5G mobile has transmissions in the 60 GHz range. Very line of sight. Low latency. Requires LOTS of tower sites as it doesn't travel far or penetrate building well. It's in the ionizing range that can damage DNA. That's the origin of complaints.
5G can leverage MIMO/beam forming techniques to put more signal directly to a device. That's available in current wireless routers in the 2.4 Ghz / 5 GHz with multiple antenna arrays.
Correct, not the same technology, but pretty much the same conspiracy word for word. Just saying.
