# 2.3 Setting Up Devices on a Local Area Network (LAN)

#### 2.3.1 Why Set Up a LAN?

The real-time image transmission for drone surveys has two parts:

Drone to Remote Controller (Get3d Reaction APP): The DJI M3E drone's built-in O3+ module handles this wireless transmission.

Remote Controller to Modeling Computer: Users need to set up a local Wi-Fi network (LAN) on-site for this connection. Currently, it uses short-range UDP and TCP protocols.

#### 2.3.2 How to Set Up a LAN

To ensure smooth real-time transmission of drone images for processing, you'll need a local Wi-Fi network (LAN). Here are some devices you can use to set one up:

l Wireless network adapters

l Mobile phone Wi-Fi hotspots

For detailed instructions on setting up a LAN with each device, refer to section 3.1.1.1.

## 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://docs.get3d.ai/user-help-center/get3d-reaction/essential-prerequisites-for-product-usage/2.3-setting-up-devices-on-a-local-area-network-lan.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.
