Except StarLink cannot possibly provide the same bandwidth, latency, and throughput a fiber connection can. Because of physics.
I can either share my 10G symmetrical connection with nobody, or with 200 others.
And, Fiber costs me $70 a month. Starlink, with worse performance, costs 4x more.
In principle I agree with you, but as a network guy, somewhere, between you and the server you are connected to, the bandwidth is shared. The only question is just where and how much bandwidth (well network throughput) there is to share. I work for a large university and our main datacenter has 10GbE and 25/100GbE connections between all the local machines. But we only have about a 3-5gb connection out to the rest of the world.
Now don’t get me wrong, I’d 100% rather have a symmetrical fiber connection to the ISP than something shared like radio or DOCSIS. I used to live in a neighborhood where everyone had Spectrum and about 5-6 PM the speed would plummet because cable internet is essentially just fancy thinnet all over again. Yes I’m old since I used to set up thinnet :)
PS: I would kill for $70 fiber where I am now. Used to have it but we moved to the sticks and I miss it terribly.
But the difference here is that on a fibre connection the shared portion goes over higher speed trunks which gives you most of that 1Gbps bandwidth. A wireless connection has a limited number of slices in the same band that it can share.
It's the same issue with too many people on a single WiFi connection.
Yep very true.
To me the main benefit of the direct fiber connection is the symmetry. With cable here I’m “supposed” to get “up to” 1000mbs down but my upload speed is at best 40. Moving large files back and forth to work is very painful.
