While it is possible to connect a Phone or Tablet wirelessly through the WiFi Hotspot functionality, using a USB tethering solution is actually recommended. Disabling the WiFi Hotspot will reduce any interference in the reception of the signals from the Air SBC.

* Connect your Android smartphone or tablet via USB to the Ground SBC.
* Enable USB-Tethering in the options of your smartphone (note, some smartphones don't support this out-of-the box or seem to have this function disabled, you may need a 3rd party app to make USB-Tethering work with your device)

You can now connect using the [QOpen.HD](/open-hd/master/ground-station-software/qopen.hd-recommended.md) app or any other ground control software.

## 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://openhd.gitbook.io/open-hd/master/advanced-setup/usb-tethering.md?ask=<question>&goal=<endgoal>
```

`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.
