# @ohos.net.sharing (Network Sharing)

The Network Sharing module allows you to share your device’s Internet connection with other connected devices by means of Wi-Fi hotspot, Bluetooth, and USB sharing. It also allows you to query the network sharing state and shared mobile data volume.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
