# preferredPeakBitRateForExpensiveNetworks

A limit of network bandwidth consumption by the item when connecting over expensive networks.

```
nonisolated var preferredPeakBitRateForExpensiveNetworks: Double { get set }
```

## Discussion

When this value is nonzero, the player attempts to limit item playback by the specified bit rate when streaming over an expensive network, such as a cellular data plan. If the system can’t reduce the bit rate to meet this value, it reduces it as much as possible while it continues to play the item.

> Note:
> The value of the ``doc://com.apple.avfoundation/documentation/AVFoundation/AVPlayerItem/preferredPeakBitRate`` property applies unconditionally. This property value has no effect if this property value is less restrictive than the ``doc://com.apple.avfoundation/documentation/AVFoundation/AVPlayerItem/preferredPeakBitRate`` value.
