# Bandwidth

NDI operates most efficiently in a dedicated network with high bandwidth and high availability. This contrasts with unmanaged environments such as the public Internet or networks where video rides along with data without priority.

Gigabit (1000 Mbps[^1]) networks are essential in production workflows. A typical NDI stream consisting of 1080 60P video yields a data rate up to 150 Mbps per stream. This extremely efficient stream is designed to have very low latency and allows multiple streams to be stacked together on a single Gigabit network. Even so, a production environment may require more capacity based on a simultaneous number of NDI streams required.

The following tables are intended to calculate bandwidth needs based on video resolutions and frame rates. It should be noted, however, that NDI is not deterministic. The bandwidth needed for NDI should be based on the determination of the [average utilization required](#user-content-fn-2)[^2].

{% hint style="info" %}
**NDI HX1** is a legacy format that will eventually be discontinued. As such, there are not reference tables for it. Contact our [technical support team](mailto:support@ndi.video) if you have any questions.

[^1]: Mbps (Megabits per second) is a unit of measurement for data transfer speed, with one megabit equal to one million bits. Network transmissions are commonly measured in Mbps.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.ndi.video/all/getting-started/white-paper/bandwidth.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
