No, you do not always need Wi-Fi for screen mirroring.
While Wi-Fi is often used for screen mirroring, many built-in protocols facilitate mirroring without an active internet connection. These protocols create a direct connection between devices, allowing for screen mirroring to occur even offline.
Here's a breakdown:
- Screen Mirroring Without Internet: Many screen mirroring technologies operate independently of the internet by establishing a direct wireless connection between the sending and receiving devices.
- Protocols That Don't Require Internet:
- AirPlay: Apple's AirPlay can function without an internet connection, creating a direct peer-to-peer connection.
- Cast: Google Cast can also work in a local mode without internet access.
- Miracast: Miracast is designed for direct device-to-device mirroring and doesn't require a Wi-Fi network or internet connection.
Therefore, while some screen mirroring methods rely on a Wi-Fi network and, consequently, an internet connection, many established protocols offer offline capabilities. So, it's possible to wirelessly screen mirror without an internet connection.
