IT is true.  That symmetrical aspect - upload speed similar to download bandwidth, compared to a higher ratio ul/dl - is a great benefit in fiber and ADSL for home users.  Maybe the latency ratio could also be considered. > > > Also the SLA.

I suppose it is not yet possible to compare the SLA of starlink Community gateways, since the starlink Community gateways seem not to be deployed already.  But I dont really know. Alex PS: I am not sure what you mean by the SLA aspect (service-level agreement).  Maybe you mean a form of higher reliability and stability of the user link. Ku band (12GHz-18GHz) is what typical starlink uses to end users. Starlink Community gateways might also use Ku band, I think. However, the photos show these spheres of 'teleports' which probably use something higher than Ku.  I dont know what freqs these teleports use; and dont know either whether the Community gateways will use that Ku, or use the D-band (120-170GHz) recently reserved by 'ESSAFI II for starlink at ITU. Then there is this Starlink Direct which promisses data (maybe higher bandwidths?) to unmodified smartphone users in year 2025, which might also be used for communities, albeit much smaller ('tethering' WiFi technology).  That is at 2.6 or 3.6 GHz (unmodified smartphones). JIOSpace fiber seems to be at MEO altitudes and also for unmodified smartphones,, hence around 2.6 or 3.6GHz. Do you think the 'SLA' of smartphones is high? > > > _______________________________________________ > Starlink mailing list > Starlink@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/starlink
