Many of you are familiar with Wi-Fi and Wi-Fi hotspot and have been making use of these two wireless network technologies almost on daily bases to share internet networks and other resources, but not many of you might know much about the Wi-Fi Direct and how it really works.
So we have decided to throw more light on those 3 keywords especially the Wi-Fi Direct in order to enable those with little or no knowledge about it to get to understand what it truly represents.
Starting with Wi-Fi, we believe that Wi-Fi is now becoming a popular house hold name and that you can find on many consumer electronics devices that you and I use on daily bases.

You can as well want to liken Wi-Fi Direct as the way Bluetooth works but with much faster means of transmitting data and again with Wi-Fi Direct, only one of the Wi-Fi devices need to be Wi-Fi Direct compliant to establish that peer to peer connection for data transfer.
One of the features in your smartphone that requires the use of Wi-Fi Direct is the Wi-Fi Display that allows you to screen cast.
