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."
Got a "smart" electric meter? Look at that as a sever station. Data is sent back into the "network" and collected at the meter the sent out as packets.
I bet you could build a device that does inline in your service power that could defeat this. But it would need to be phisicaly in the main circut and wireless coms between the toaster fridge and smart meter base would be another issue. Also smart meters are wireless so basicly a listening device either way.
