Specs for minimum ping of some internet technologies:
2G (100–400 Kbit/s) 300–1000 ms
3G (0.5–5 Mbit/s) 100–500 ms
4G (1–50 Mbit/s) < 100 ms
ADSL+PPP (0.1-200 Mbit/s) 40 ms
Cable (2 Mbit/s - 1 Gbit/s) 80 ms
Fibre (1 Gbit/s - 100 Gbit/s) 5 ms
Note that this latency is just the transmission delay, it does not send your data more than a few hundred meters (technically up to 200km for fibre, but usually the actual distance sent is still hundreds of meters).
After that, you should consider that your data is probably being sent at least to the capital of your state, or some other large city, before there is any routing (meaning a packet to your neighbor gets sent to this large city and back). This distance tends to be more than the distance to LEO and back (but of course, your wouldn't be sending it straight up to LEO but at an angle, so the number of satellites makes a large difference. At 4000, it won't be a huge angle).
So this can still beat every technology except perhaps FTTH, which is hugely expensive and not widely spread at all. Furthermore, it can beat every mobile last mile technology.
- ricardobeat 10y agoWhere are those numbers from? I get a consistent 12ms ping with my cable internet (200Mbps) to local cloud servers, and have seen as low as 1-4ms on fiber.
- Benjamin_Dobell 10y agoYeah, I'm pretty sure they're made up, and they lack context. 40ms for ADSL... From where to where are you pinging? Gamers will regularly achieve ~20ms pings to other gamers on the same continent. Where as pinging around the other side of world (under-sea cables) is going to add approximately 150-200 ms. Also FTTH vs. ADSL vs. Cable really shouldn't make much difference with regards to ping (they're all fibre for the majority of the distance). The main reason FTTH (or even FTTN) networks tend to have a quicker ping is because they usually have newer/faster routing hardware running on them.
- candiodari 10y agoYou should try Australia. Undersea cables definitely adds more than 150-200ms (but I guess you mean the Atlantic) to everything here.
- pugz 10y agoHe _did_ say on the same continent. 150-200ms within Australia would be considered pretty slow.
- Benjamin_Dobell 10y agoI have tried Australia... it's where I live ;) ~150ms is how much time it takes for my packets to travel the ocean from Australia to USA. The UK in total is around 350ms (including lots of land routing). That's mostly due to non-optimal routing, it shouldn't be quite that slow.
