<p>It is indeed excellent news to hear that they achieve such a low
latency. It is worth noting.</p>
<p>In addition to fq_codel, cake and libreqos (acronyms I simply
cite), if I may speculate how to further decrease the latency:</p>
<p>- lower the sat altitudes, maybe at 350km or even at 70km.
These are altitudes where starlink sats seem parked at times,
maybe right before reaching their stable 500km altitudes. It
means they can stay there, maybe for a shorter time than the times
they stay at 500km, but still, for some time.</p>
<p>- make the antennas on the sats more 'wide-angle' so to speak,
such as to make multiple spots on the ground, possible very
distanced, rather than one single spot straight below the sat.</p>
<p>- add sat-to-HAP links. (high-alti platforms, i.e. 20km-to-70km),
sat-to-plane, sat-to drone links (altitudes 500m-20km).<br>
</p>
<p>- add sat-to-other-constellations' sats links.</p>
<p>- have a dynamic IP routing system between sats and HAPS
naturally finding shortest paths, i.e. lowest latencies.<br>
</p>
<p>I think one could target a 1ms latency.<br>

<div>I of course, am very interested in y'all´s external
measurements of how well starlink is doing. For me, it is
fantastic - 30Mbit uploads nowadays, 0</div>
<div>latency on the upload (how?) <a

<div>I also keep hoping that the rest of the ISP industry is now
paying attention and deploying stuff like fq_codel and cake
and libreqos, but, ah well - I will settle for starlink
blowing past a lot of dsl and cable and finding ways to get
their density up.</div>
