@stman @50htz @vidak @theruran @forthy42 merely doubling the baudrate per wavelenght compared to #RONJA can yield 100MBit/s at 5 wavelenghts, whilst offering us better link budget & range.

Not to mention #IrDA as a protocol could be repurposed as a diagnostics / link renegotiation channel and even as ultra-long-range / narrowband & broadcasting (PtMP) solution (see #IrLAN)…

Note that the maximum possible range achieveable under lab conditions will be way better than the real-world outputs, simply because not only does humidity and rain exist, but where it doesn't (i.e. deserts) thermal stress and expansion is moving things out of optimal alignment over the day...

  • And in a lab you don't have things potentially disturbing it.

Of notable value may be the #IrLAN stack, given that it's designed to tunnel #Ethernet through a 4Mbit/s FIR link.

  • I'm pretty sure that the same can be applied to visible light without much of an issue...
