Most people shopping for internet look at one number: download speed. If a plan says 500 Mbps, it must be good. But three other numbers matter just as much for remote work, and none of them show up on the marketing page.
Latency is how long a single packet takes to reach a server and come back. Under 50 ms is fine for video calls, under 20 ms is great. Jitter is how much your latency varies over time — high jitter is why calls stutter even when everything else looks OK. Packet loss is the percentage of data packets that never make it. Even 1% packet loss is enough to visibly degrade a video call.
You can check all three by running a speed test that includes ping, jitter, and — where available — packet loss. If your download speed is fine but your jitter is above 30 ms or your packet loss is above 1%, your video calls will feel bad no matter what plan you upgrade to. Fixing those often means better hardware, wired connections, and sometimes a switch to fiber. For a fuller checklist on what to look for in your connection, Remote Rebellion's remote job internet requirements guide covers all of it.
