Geosynchronous is ~ 36000 km. Medium is up to 22000 km, and LEO is about 200 km. I think LEO will do most of the observation and defence, and MEO and geosynch will be more comms and control.OK. This is pretty interesting!
Here's an article published 1 December 2023, in which Jeff Schrader (Lockheed Martin) discusses working with Intel on neuromorphic processors (albeit under the misspelling "neomorphic") for distributed command, control, autonomy, and on-board decision-making.
That Schrader refers to this as enabling “top-level smarter systems” and “working with Intel” confirms that neuromorphic is no longer speculative, but rather it’s under active evaluation. Lockheed is testing solutions now. So, if Intel is in the running, BrainChip could be considered as a complementary or competing solution, particularly for ultra-low SWaP edge AI.

There will be a lot of LEOs, fewer MEOs and a large handful or two of geosynchs.
I saw somewhere that they have tested laser comms between LEOs. This would be harder to tap into than wireless, but would require good stability control.
Australian laser company BluGlass (BLG) has a MoU with Advanced Energetics who make directed energy weapons (short burst high power lasers).
