Rain reduces the speed and increases the latency (I'm actually not sure why the latency increases, it's not like the signal has to go further) but, it still works.
- bodhiandphysics 5y agoBecause it needs to repeat messages more till you get a clear message through
- martinald 5y agoNot sure about that? In a UDP based ping it's fire and forget so wouldn't repeat, so would show as packet loss not increased latency. Unless the physical layer is using more FEC and using longer "timeslots" to get to transmit the payload. But even that seems unlikely to cause major latency increases?
- wmf 5y agoThey may be using link-layer ARQ which resends corrupted packets instead of dropping them.
- aero-glide2 5y agoMaybe the dish is connecting to farther away satellites closer to the horizon due to packet losses on the first satellite?
- jcrawfordor 5y agoIt's vanishingly rare for radio-based networks to actually rely on high level IP behavior for redelivery, as it's much faster to fix these issues on the single radio link than to wait for things to go round trip. The data link protocol typically has its own reliable delivery implementation that will result in multiple retries. This results in increased latency in poor network conditions. 802.11 behaves similarly.

- whoisburbansky 5y agoDoes your latency measurement account for dropped packets? Rain-caused attenuation could cause more packets to be dropped, increasing latency if you measure it as an average over total packets sent, instead of just across packets that get delivered?
