What is Wi-fi Direct?
When someone mentions Wi-Fi most people will immediately think of surfing the internet, but there’s more to it than just that. The list features on our Android smartphones is quite covering and most of them either just fly by unnoticed when we see them, or we just ignore them. Wi-Fi Direct has been one of those, but we’ll explain to you what it is, why (and for what) you should use it and how to set it up.
Wi-Fi Direct is a certificate of the Wi-Fi Alliance (worldwide network of companies that brings you Wi-Fi), which includes over 600 members such as Apple, LG, Intel, Microsoft and Dell. A host of devices these days are Wi-Fi Direct compatible most notably Tablets, Laptops, Digital Cameras. The Samsung Galaxy S (launched in 2010) was one of the first smartphones to include this feature, and as of Android 4.0 Ice Cream Sandwich, all Android smartphones have this feature included natively.
Wi-Fi Direct can be seen as a sort of second-generation Wi-Fi, as it allows compatible devices which do not have their own internet connection, to establish a mutual connection with ones that do (Hotspots, modems or routers). Wi-Fi Direct lets you can build up a wireless network between multiple devices.
