I'm not sure how LEO regs could be set up or enforced. There's no geographi= c division in LEO itself.=20 Transmission at the earth intentionally might be regulated at national leve= l by the target. That's been traditionally accomplished by regulating earth= endpoints as the jurisdiction. ITU doesn't have a Space member that represents space, and it has no enforc= ement arm. Now the US Space Force could nominate itself as the enforcement arm of the = UN. That won't fly, but Trump could rattle swords.=20 We have a complex Law of the Sea after hundreds of years. But still, it's u= nclear who has jurisdiction over things like radio on the high seas. Situation isn't at all as mature in space. We have some treaties.... -----Original Message----- From: "Dave Taht" Sent: Tue, Oct 16, 2018 at 11:10 am To: dpreed@deepplum.com Cc: "Make-Wifi-fast" Subject: Re: I wonder if UWB is legal in space... I thought that would get a rise out of you. :) I do hope spacex hires an engineer that "gets" that the rest of the solar system is a greenfield environment. Is it really just LEO? I had figured the regs extended to geosync, and any innovation would have to happen beyond the lagrange points. My understanding of the starlink effort is that it's mostly LEO, and I'd hoped for insanely fast sat to sat coms somehow. lasers perhaps.... On Tue, Oct 16, 2018 at 8:06 AM David P.
