As noted above, the super-nodes 410A to 410C may be configured for both longer-range optical communication with other super-nodes and shorter-range RF communications with nearby sub-nodes 420. For example, super-nodes 410A to 410C may use high-power or ultra-bright LEDs to transmit optical signals over optical links 402, 404, which may extend for as much as 100 miles, or possibly more. Configured as such, the super-nodes 410A to 410C may be capable of optical communications at data rates of 10 to 50 Gbit/sec.
This would be roughly hops to cross the Atlantic at the shortest point between the US and EU.
Maybe there is some steering tech to keep nodes where they are needed i.e., solar fan but could it overcome the wind? They apparently get caught in 5mph to 20 mph even in the ideal 18-25km range. Number of balloons to cross the Atlantic or other wide space might be quite high with such movement.
Regardless its interesting as another free space optical tech that could work with LiFi, and maybe Outer Net to spread Safe at least regionally. An Outter net approach would seem inevitable when Safe is at scale and the expense is less of an issue.
