# Synchronizing via Wi-Fi

## Synchronizing via Wi-Fi

Mapeo Desktop can synchronize data via Wi-Fi with other <img src="/files/sz1WZdsujIFD7iZcMkYS" alt="" data-size="line"> computers or <img src="/files/jHKAm1YaXkCXEWggHByy" alt="" data-size="line">smartphones that use Mapeo. This is a good sync option when devices are near each other and it works with **no internet connection**.&#x20;

Requirements:

* **Both devices need to be connected to the same** <img src="/files/ntRMR42fWz6FCGgGA1ot" alt="" data-size="line">**Wi-Fi network**\
  For devices to sync, both need to be connected to the same Wi-Fi network. This Wi-Fi network does not need to have an internet connection. <br>
* **Both devices must be using the same configuration**\
  It is only possible to synchronize with devices that use the same [configuration](/complete-reference-guide/customization-options/custom-configurations.md#about-custom-configurations). For more on how to import configurations, see [Importing configurations to Mapeo Desktop](/complete-reference-guide/mapeo-desktop-installation-setup/importing-configurations.md).

To synchronize, follow the steps below:

## Connect to Wi-Fi

Connect both Mapeo devices to the same Wi-Fi network. In offline environments, a local Wi-Fi network can be created using a <img src="/files/8p0Gg8YshcjHDKJKy9Hf" alt="" data-size="line">mobile wireless router or a third device capable of serving as an offline <img src="/files/UzsE5bWaPrfCJxz7Ltc6" alt="" data-size="line">hotspot.&#x20;

For more on how to create a local Wi-Fi network or connect to Wi-Fi, see\
[I want to create local Wi-Fi networks](/complete-reference-guide/troubleshooting/solving-sync-issues/creating-local-wi-fi-networks.md)\
[I want to connect to Wi-Fi](/complete-reference-guide/troubleshooting/solving-sync-issues/connecting-to-wi-fi.md)
{% endhint %}

## Enter Synchronize mode

In order to synchronize, both devices must have the **Synchronize** screen open.

In <img src="/files/J7DJz0EhOaiOgQRUbNm6" alt="" data-size="line">Mapeo Desktop: Click on **Synchronize** in the **Mapeo modes** panel.

![](/files/dIPuxXqSvPrrYuyncEne)&#x20;

Devices available for syncing will be listed on the **Synchronize** screen. <br>

{% hint style="info" %}
Remember that in order for a device to appear in the list, it must be connected to the same Wi-Fi network, have the **Synchronize** screen open, and be using the same project configuration. \
\
You can confirm which configuration Mapeo Desktop is currently using by consulting the white bar at the bottom of the **Synchronize** screen.\
\
For troubleshooting on this step, see [I have sync issues](/complete-reference-guide/troubleshooting/solving-sync-issues.md).
{% endhint %}

## Start synchronization

Once available devices appear in the list, confirm the identity of the device you plan to synchronize with by consulting the unique identification number on the other user's device.

{% hint style="info" %}
To see the unique identification number of a Mapeo Mobile device, check the right side of the navy blue bar on the **Synchronize** screen in Mapeo Mobile.
{% endhint %}

In Mapeo Desktop, click on the **SYNCHRONIZE** <img src="/files/VtHzeTnhgSjCdEbm0Tke" alt="" data-size="line"> button below the device name to begin the exchange of data.&#x20;

{% hint style="warning" %}
**Important**: Keep the **Synchronize** screen open on both devices until the synchronization process is complete.
{% endhint %}

## View synced observations

To learn about viewing and managing synchronized data:

* In Mapeo Desktop, continue to [Viewing observations](/complete-reference-guide/mapeo-desktop-use/using-mapeo-desktop-to-manage-mapeo-mobile-data/viewing-observations.md)
* In Mapeo Mobile, see [Syncing data via Wi-Fi](/complete-reference-guide/mapeo-mobile-use/wifi-sync.md#view-synced-observations)
