# preparesCellularRadioForNetworkConnection

Indicates whether the receiver should prepare the cellular radio for imminent network activity.

```
var preparesCellularRadioForNetworkConnection: Bool { get set }
```

## Discussion

Apps that scan video data output buffers for information that will result in network activity (such as detecting a QRCode containing a URL) should set this property `true` to allow the cellular radio to prepare for an imminent network request. Enabling this property requires a lengthy reconfiguration of the capture render pipeline, so you should set this property to `true` before calling [`startRunning()`](/documentation/AVFoundation/AVCaptureSession/startRunning()).

Using this API requires your app to adopt the entitlement `com.apple.developer.avfoundation.video-data-output-prepares-cellular-radio-for-machine-readable-code-scanning`.
