As you may know, Ubuntu Touch is the mobile version of the Ubuntu desktop system, currently pre-installed on Bq Aquaris E5, Bq Aquaris E4.5 and Meizu MX4, but also officially supported on the Nexus 4 and Nexus 7 devices.
Recently, the Ubuntu developers have announced the immediate availability of Aethercast, a feature for connecting the Ubuntu phones to the Miracast protocol, a Wi-Fi Display feature that permits a device to connect to a monitor via wireless.
Since only the Nexus devices can output video via an MHL connection, Canonical had to discover a hardware solution to use external monitors connected through wireless.
Canonical’s biggest plan is to make Ubuntu the first mobile-desktop convergent operating system. A convergent system is an OS that uses the same source code for both mobile and desktop devices and has an interface that behaves different, depending on the screen size, being full-screen only on mobile devices and with adjustable size on desktops.
