Great suggestion, but it may not be feasible soon. I’ll share my full thoughts in about half an hour.

It’s not feasible. Several essential elements are missing from the picture. If these objects still exist in orbit, they must connect to a relay for transmission and reception. Imagine a fixed receiver or transmitter at your home, with a satellite device 3000 miles away—like between San Diego and Boston. The most likely delay on a direct land connection would be around 70 milliseconds. AT&T reports about 63 milliseconds between San Diego and New York City. What’s the quickest possible delay for a satellite link? Likely near 70 milliseconds. AT&T claims 63ms between San Diego and NYC. Now, what’s the fastest possible time between a satellite vehicle and its broadcast hub? That could be close to a few hundred milliseconds. Watching live news with rapid blinking is nearly instant—literally seconds. To reach such speeds, the satellite must stay low in orbit: https://www.researchgate.net/figure/Hand..._304557281. SDSN refers to software-defined satellite networking. Being nearer to Earth means better coverage. If you want 63ms, you need to be close enough to the beam center on each side. The graph describes handover—like switching towers when driving. But satellites move constantly, unlike a phone signal. The FCC’s Starlink specs seem overly optimistic: http://licensing.fcc.gov/cgi-bin/ws.exe/...ufferda647. For Ka and Ku bands, VLEO orbits at 2000km, you’d need a low orbit to hit the target. Options include: a) direct land-to-VLEO, b) land-to-VLEO → land, c) land-to-VLEO → LEO → land (longer), d) multiple hops. The data suggests VLEO is for subscribers, LEO connects them. Each switch adds delay. In the Starlink docs, they mention both LEO and VLEO, but mostly focus on LEO for users. Every time the constellation moves, a handover is required. Even under ideal conditions, it can’t beat fiber-optic lines. What I missed was focusing only on AT&T’s fixed points, not subscriber locations. San Diego to Boston shows 69ms; California stays under 20ms. Assuming 25–35ms as SpaceX claimed to the FCC, latency remains higher than land connections. You’ll notice real savings only at much greater distances—like Alaska to Australia—or in rural areas with poor infrastructure. Starlink could work for basic internet, but using it for calls or gaming would be extremely challenging due to weak signal quality. Full transparency: this is based on educated assumptions since no one is currently using Starlink. Past services like HughesNet always offered very slow speeds, and beyond your control, latency often reaches 500ms or worse.

The idea seems uncertain but could work in theory. SpaceX aims to place satellites around Earth so they stay nearly overhead, always providing coverage. Signals would travel between them and then be sent directly to the destination. In this simplified view, the total path length equals the satellite height plus the gap between satellites plus another satellite height. The fastest possible delay comes from dividing that distance by light speed. The graph confirms the satellite path is always slower than a ground route, though at Starlink’s orbit the extra delay stays minimal—just a few milliseconds. Including GEO adds more latency since signals must pass through multiple satellites. Practically, using the same tech in space versus on Earth would only change travel distance, which is a big assumption.

I believe the main challenge lies beyond just reviewing FCC documentation and existing patents. It’s clear that speed limitations are tied closely to the speed of light, making fiber the fastest option. The performance would still lag behind wired connections unless the devices themselves are optimized. The diagrams I found focused on transition phases and mentioned LEO/VLEO satellites operating in Ka-band above 12GHz. Some studies suggest handoff times around 210ms, though these are based on assumptions. If Starlink claims under 40ms at launch, it could match or exceed traditional cable speeds. However, if the handoff delays are accurate, multiple routing paths could exist for data packets. At a minimum, this technology offers a choice—especially for those without alternatives. For urban residents, mounting antennas on buildings is often banned due to structural and safety concerns.
