I gave the video a watch, was definitely interesting.

This seems great for people who are worried about radio waves or wifi signals.

This doesnt use any of that, seems quite ingenious. The video says something along the lines it communicates with light in a form of morse code.

My guess is the light is dimming at such a frequency your human eye cant perceive it.... and its communicating 0's and 1's this way.

Quite ingenious really.....depending on how well it works I could see lots of people choosing to use this instead of wifi.

Those powerlan network adapters blow, even though in theory should work, and requires it to be all on the same circuit.

I get where your going with this and the supposed self assembling nanochips in the shot. (lets hope it wasnt designed by some god ai).

But this provides very little power, and light doesnt penetrate teh skin very far...

5g on the other hand......and why they had to build coverage for 90% of the planet is awfully curious.

However, the depth of penetration in human tissue (skin, muscle and tissues with high water content) for a frequency of 10 GHz which lies in 5G frequency spectrum is about a few mm.

Short-wave visible light penetrates typical tissues to a depth of 0.5–2.5 mm. In this case, both scattering and absorption occur, with 15–40% of the incident radiation being reflected.

Just a bit a more.
