Anon shares on Wifi Lightbulbs. Can anybody who knows of this topic shed some light?
If you haven't heard about "LIFI" you will.
Following is a brief explanation:
"At its essence, LiFi operates as a Visible Light Communications (VLC) system, promising unparalleled wireless internet speeds. Central to this system are LED light bulbs. These bulbs emit swift light pulses, imperceptible to the human eye, laden with information. It’s akin to an advanced, hyper-speed Morse code. Devices fitted with the requisite receivers decode this influx of data at breathtaking speeds. Demonstrated potential transmission rates for LiFi have even surpassed 224 Gbps, a pace that dwarfs WiGig, one of the most rapid Wi-Fi technologies."

It has been known for a long time you can do various protocols including Ethernet over the power lines. Several huge US power companies wanted to deliver internet over the power lines, and it's doable, it's main source of attenuation is the type of transformers used on telephone poles. In many areas if you get the power cut on to a new address they have the option of getting internet 'bundled', they refer you to whatever local ISP works with them and get you a wildly better deal on the local internet than you could get going direct to the ISP. Now why is that ISPs let the power company skim off the top of their recurring profit potential? Quid pro quo for not using that infrastructure to deliver internet to homes because that space on their wire is already biing used.
You'd be amazed how much metadata you can get from and put onto that infrastructure. People are probably familiar with Ethernet over power line for bridging connections in their homes over their power sockets going through the breaker in their house as long as it's the right type and on the same circuit. In the last ~20 years there have been regulations dictating what types of circuit breakers must be used in new installations.
There was a guy that made some threatening video using a camcorder with no battery hooked up to the wall for power while recording ~20 years ago. The background static noise on the power line left a distinct pattern in the recorded video and audio of his masked message of threats. They were able to analyze and playback and match that background noise to triangulate him within a very close distance I don't remember if it was blocks or miles based on that match because as it turns out that background noise was being recorded by power companies, presumably as some sort of diagnostic tool similar to an expensive TDR time distance reflectometer device. The details came out in a court document where the evidence was supposedly mistakenly revealed to the public on how they narrowed him down.
I could go on about this for some time but you get the picture.
This is along the lines of what I was concerned about. Is there a device that can scramble the power fluctuation signatures of your home's power consumption? That would potentially also scramble or shift every device in your home that was powered by it (or just brick some of them kek)
May be best to have the entire house behind a double-conversion UPS so all devices use the batteries while the utility power feeds the batteries. I would think there are cheaper solutions though
