Streetlights are usually within sight of each other. Can't we just add light sensors that point at the neighboring lights and modulate the brightness by a fraction if we want to do messaging?
- amluto 7y agoStreetlights are usually white, which means there’s a phosphor, which drastically limits the modulation frequency. Also, the lights themselves (at least where I live) are owned by the city or PG&E. Good luck getting them to cooperate that deeply with carriers. Also, the lights are off in the daytime. That being said, in the absence of fog and heavy rain, optical communication between light poles isn’t that crazy.
- inflatableDodo 7y agoWas thinking mostly of messaging for the lights themselves, telling lights to tun on or off, checking that they are on or off and also that they aren't misbehaving, that sort of thing, so relatively slow modulation would probably be fine.
