"For now, Starlink internet cuts off for seconds at a time every couple of minutes" - wait, what?

Coverage is incomplete as they’re not nearly done deploying satellites. Satellite TV comes from single satellites orbiting in geosynchronous orbit, way out there where the orbital period is exactly one day.

Starlink satellites are a swarm which operates in a low earth orbit with a period of around 90 minutes, you’re constantly changing satellites much like a cell phone switches towers as you drive.

A coverage gap would probably lead to multi-minute gaps in service.

Instead I'd guess this is a delay during reorientation of the physical antenna or repointing of the phased array.

The phased array can theoretically be repointed in milliseconds, but in a rush to launch I wouldn't be surprised if it doesn't take a few seconds to lock on to the signal, do channel characterization, and adjust data routing stuff to use the new link. During that time, a bunch of packets are lost, and you then have to wait for the TCP timers to expire before retransmission.

End user ends up seeing a 5 second glitch.

So, does that mean 95% of internet users are facing even worse quality of service? or does it mean that given a very small number of participants so far, starlink is able to allocate more bandwidth to everyone?

I remember reading an analysis here on a previous posting about starlink that under load, it is going to have pretty limited throughput (on top of higher latency). I do not see how that will get solved.

> So, does that mean 95% of internet users are facing even worse quality of service?

The first sentence of the article makes it clear the 95% figure is in reference to speed.

…and only is reported by some users. Full sentence:

“Some of the participants in SpaceX’s public Starlink beta are reporting internet speeds higher than 95 percent of U.S. internet users.”

So the same could be said of regular providers? "Some users report speeds higher than 95% of the other users"...

This really needs more precise wording. What percentage of Starlink users (more than 5%?) and what's the speed difference?

When 4g/LTE was new, a coworker was an early adopter of whatever cellphone that was one of the first to support it. They were getting somewhere ~250 mbps on speed test.

Fast forward to everyone having 4g phones, now in practice I see like 1-2% of those speeds typically.

I have no idea the inner workings of starlink's protocol, but these aspects of wireless seem inevitable. once theres more simultaneous connections than in limited beta, each connection gets a smaller time slice or less frequency band, no?

I do not see how its solved either.

Currently I have rural DSL, approximately 3mbps down, 1 mbps up, but cheaper and reliable. The one person who has starlink beta is posting 200+ mbps screenshots but if everyone here connects I'm skeptical the result isn't slower, less reliable, more expensive than what's already here.

I can see that just over a day. During off-peak hours, I've speedtested around 260 Mbit/s on LTE on my iPhone (it's 10:20 PM on a weekday and I just got 230 Mbit down[0]), but during peak hours (commute hours or lunch rush), it drops to like... 20 Mbit

IIRC initial LTE (UE category 3) only supports max 100Mbps (on spec) by 15MHz bandwidth. So I had measured max 50Mbps on 75Mbps (on spec, 10MHz) network.

"but those interruptions will likely fade as more satellites are launched and coverage becomes more comprehensive."
