DIY LIFI
I’m trying to set up a LIFI system but don’t have clear instructions. Most online guides seem confusing, so I’m considering switching to a wired connection instead.
Ethernet is likely to remain faster according to common knowledge.
The concept isn't overly complex; simply flash a light to symbolize bits. In basic scenarios, one end would have a light and the other a photo detector. The challenge lies in using visible light sources that are extremely narrow in wavelength and much brighter than typical natural conditions. Then the main constraint is how rapidly the light source can adjust its brightness or intensity. Alternatively, you could adapt current tech such as higher-powered IrDA systems.
Yeah... That's not likely to happen. Li-Fi isn't really effective in lab settings with trained researchers, and it wouldn't work well at home either. You'd probably find it simpler to use an Ethernet cable connected to a USB-C adapter and run cables from the ceiling about six inches apart throughout your house for phone use.
The issue with Li-Fi lies in its likely omnidirectional design, which fails when many LEDs blink simultaneously. The receiver side also presents challenges. Essentially, Li-Fi functions like Wi-Fi but uses light instead of radio waves. Still, beyond that, fast free-space optical communication is becoming practical, though you must consider the visible spectrum's constraints and characteristics.
