# Connecting to the Internet
The Fotokite Sigma system needs an internet connection for the following use cases:
* Over the air software updates ([System Update](/fotokite-live-walkthrough/system-update.md))
* Livestreaming ([Remote Livestream & Remote Control](/fotokite-live-walkthrough/remote-livestream-and-remote-control.md), [Remote Livestream](/system-profile/remote-livestream.md))
* Upload of flight diagnostic logs
{% hint style="info" %}
Basic usage of the system (flight control, video streaming to tablet or [Local Video Streaming (RTSP)](/installation-and-integration/local-video-streaming-rtsp.md)) is possible entirely without internet connection.
{% endhint %}

For more details regarding the Network features of the Sigma System refer to the [Network Integration and Setup](/installation-and-integration/network-integration-and-setup.md) guide.

## Internet over Mobile Data - LTE
Your Fotokite Sigma system comes with a cellular modem and activated global SIM card built in. A Bring Your Own SIM configuration can be requested through Fotokite Support. Learn more in [Cellular Modem & Mobile Data](/system-profile/cellular-modem-and-mobile-data.md#bring-your-own-sim).
By default, there is a data budget of 1GB/month, which is sufficient for software updates and diagnostics. When Livestreaming is activated, the monthly mobile data budget is automatically increased to 50GB. In case you need even more budget this can be arranged with Fotokite Support.\
The cellular connection is only guranteed to work in the country where you purchased your Fotokite system. In case you are traveling to other countries and still want to use Mobile Data, please consult Fotokite support.
This connection will always be active globally as long as there is cellular reception at the systems location.

## Internet over a Customer owned Network
The system can access the Internet via a customer owned network either via Wi-Fi or Ethernet.\
Please refer to the [Network Integration and Setup](/installation-and-integration/network-integration-and-setup.md) Guide for in depth instructions how to integrate your Sigma with your own Network.\
This page highlights the most common case of connecting the System to a Wi-Fi Network.
### Internet over Wi-Fi
The system can be connected to 2.4GHz Wi-Fi networks supporting the WPA2 PSK encryption scheme.\
We currently do not support hidden Wi-Fi networks.
Use System Menu > System Connect > **Internet over Wi-Fi** in Fotokite Live to scan for networks and connect.
Successful connections will be marked as "Saved". A Fotokite system will automatically connect to saved networks in the future. However, the auto connect feature can also be deactivated if this is not required.

{% hint style="info" %}
If you have connection issues, please forget the network (System Menu > System Connect > Internet over Wi-Fi > Options) and try again.
{% endhint %}
**Caveats:**
* Only IPv4 is supported
* The 192.168.2.X IPv4 subnet is used internally by the Fotokite Sigma System. There will be address conflicts if the customer network is configured with an overlapping IP address range. This cannot be changed.
### Internet over Ethernet
The Sigma can also connect to the Internet via a wired Ethernet connection.\
Please refer to the [Network Integration and Setup](/installation-and-integration/network-integration-and-setup.md) guide.

## 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, and the optional `goal` query parameter:
```
GET https://manual.fotokite.com/fotokite-live-walkthrough/connecting-to-the-internet.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
