The other problem with satellites is latency (the time it takes the signal to move from point A to point B). Telecom satellites orbit 26,000 miles above the equator, so the minimum time for the round trip will be ~0.3 seconds but much longer at higher latitudes. Using cables it’s usually less than 0.025 seconds.
Do both signals move at the theoretical speed of light, or are they limited by air/cable friction factors?
Ivy Bells- the sequel.
Close enough to the speed of light as to make no difference. The chief limiting factor is the number of gateways. Each router on a network acts as a repeater, so it takes a bit of time to process the signal and re-transmit. The more “hops” in a connection, the slower the transmission. You can see the effect by using the tracert command in Windows.

Now that right there is FUNNY!
If these are private and owned by corporations, then Obama's declaration that the "internet" is a utility to be federally regulated amounts to a 5th amendment taking. He's either taking the servers, storage, and cables outright and nationalizing them, or he needs to pay fair price for the property takings.
If he is 5th amendment taking for "public use," he should be sued in court to explain that use. I bet in that case, the Kelo case would come back to haunt us, as that ruling transformed "public use" into "public good." Public use meant direct use, as in a highway, school, or civic building. Public good meant indirect use, as in the tax benefits of other owners using the property in allegedly more profitable ways.
Obama will claim public good of a nationalized internet, but won't pay a dime for taking control of private assets.

No. Fibre runs around 2/3c. The light doesn’t travel straight along the fibre, it bounces back and forth within the fibre cable.
Thanks! Great information.
Just tried it; interesting data.

We have the same provider. Mine is Verizon DSL and this morning speed tests from four different test sites had me at .37Mbps. I pay for 1Mbps.
I live 41 miles from the White Hut and yet the only other provider in my area is Comcast and they are using the same equipment as when it was owned by Adelphia about 11 years ago. My neighbors who went to Comcast from Verizon say they made a mistake as their Internet speed is no better than the bad Verizon DSL and costs more.
I should just go back to dial up.
Gives me a new appreciation for the services available here, where 3mbps is considered slow and is dirt cheap. My connection is rated 30mb down/5mb up and consistently tests >90% of rated speed. I’m paying $45/month, while 10mbps can be had for ~$30.
Porn cats, if ya know what I mean........
Fascinating stuff, love to learn things on FR, good post!
Their reputation is so toxic that here in the midwest they are using the alias "Xfinity" now.
I checked Comcast and they want $84.99/month for 25Mbps, which our neighbors tell us is a total fraud. Verizon DSL told me they have no intention of upgrading my area so we will not get any higher DSL speeds. I asked about FIOS as they just put in all the equipment and fiber two homes from mine at the intersection of our cul de sac and the Verizon FIOS people said that even though the equipment is there they will not let the ten homes on our street have FIOS.
We are literally stuck with two companies that will not service us at all and yet we live in the Washington DC area.
AFAIK, these cables have been laid by private communication companies. Learn More.
Start contributing to the local Democrat party. I suspect you’d see that problem fixed pretty quick.
