Jitter

The variation in latency over time, affecting real-time applications like video calls.

What is Jitter?

Jitter refers to the variation in the delay of packet delivery over a network. Ideally, data packets travel at regular intervals, but jitter means they arrive inconsistently — causing stuttering, lag, or lost connections.

Why Jitter Matters

Jitter affects real-time communication like video calls, online gaming, VoIP, y live streaming. It leads to choppy audio, frozen video, and unpredictable connection issues that can frustrate users.

Jitter vs Latency

Latency is the total delay in sending and receiving data. Jitter is the inconsistency in that delay. A connection may have low latency but high jitter, resulting in an unstable experience.

What Causes Jitter?

  • Network congestion or bandwidth overuse
  • Wi-Fi interference or signal degradation
  • Outdated or overloaded routers and modems
  • Inconsistent routing by your ISP
  • Devices competing for resources on the same network

How to Reduce Jitter

  • Use a wired Ethernet connection for greater stability
  • Upgrade your router or firmware
  • Reduce the number of active devices on your network
  • Pause large downloads or cloud backups
  • Contact your ISP if jitter remains consistently high

Preguntas Frecuentes

Jitter under 30 ms is generally acceptable for VoIP and video calls. Lower is better, especially for gaming or real-time meetings.

Jitter causes poor audio and video sync, freezing, or dropped speech during calls — especially noticeable on group calls or screen sharing.

They’re both important. Jitter is more disruptive for real-time applications because it causes erratic performance, even if your latency is low.

Yes. Weak signals, interference, and distance from the router often contribute to jitter. Ethernet connections reduce this problem significantly.

Not always. Jitter is often due to network instability, not just speed. But more bandwidth and better equipment can help reduce it.
