Miracast technology made a debut in 2012 with Google adding support for it starting Android 4.2 Jellybean. In simple words, Wi-Fi Direct creates a direct (hotspot) connection between devices. You can skip it, and the devices will connect directly using Wi-Fi Direct. While they work on a Wi-Fi router too, it’s not a necessary part of the connection. Miracast devices use Wi-Fi Direct technology to connect. Most Smart TVs now come with built-in support for Miracast, so you don’t even need a Miracast dongle or stick to mirror content. The cool thing about Miracast is that it’s cheap for the dongle or stick can be from a brand like Amazon or a local brand costing just a few bucks. It’s a technology built inside Miracast supported devices such as dongles, streaming sticks, phones, and laptops. Miracast isn’t a dongle, a stick, or a specific product like Chromecast.
