The problem with IR laser comms is its only p2p, LoS
Cheap, works. Use whatever works. But for moving bandwidth, digging or stringing fiber and copper, or mounting laser... seems hard to beat on cost X speed basis. Maybe source simple IR laser module kit from China if it's still too high at retail due to fancy targeted-to-business-user remarketing bullshit. Generic RF kit, outside of WiFi std, probably isn't exactly cheap yet. Aren't [the rest of] free space optics solutions still big $$$? ...
A nice complement may be possible in the near UV (200 - 350nm, with a peak at about 250nm)
Not if it burns unaware people's eyes out.
the molecular vibrational modes of ozone. Due to atmospheric aerosols beams
Ozone densities at ground level under varying weather conditions... unreliable?
at these frequencies.aimed at low-to-mid angles can be sufficiently dispersed so as to enable no-LoS.
Due to the upper atmosphere ozone these frequencies are greatly darked in most areas of the globe even at noon.
Is this UV / freespace tech at consumer production and price level, links? At Urban/Suburban environments densities distances, you probably want each node able to move at least 100Mbps over two simultaneous physical links to two other nodes for less than around $750 per node. 1 or 10 Gbps is trivial over fiber, and is easy to run to, or around, neighbors. Imagining entire buildings, neighborhoods... linking them up, serving as each other's transit... easily possible. Co-ops already do buildout models, but they're usually not per-node ownership, not mesh protocol'd, and not open to linking up, including due to contractual baloney that does not exist with true p2p. Taking that to fully distributed, open-neighbor to open-neighbor... from apartments, to farmland... that's the next level. Similar to cryptocurrencies... open p2p routing standards, and philosophy and responsibility of individual ownership, needed to prevent problems of centralization... are key. The independent nature sells itself under network effects.
