Wi-Fi Direct is an emerging wireless standard that allows you to create a create a connection between any two devices without going through a wireless router. Want to create a Wi-Fi hotspot, connect your computer or smartphone to your printer or stream movies from your tablet to your television? There is a good chance that Wi-Fi Direct is doing the heavy lifting.
How Wi-Fi Direct Works
Imagine that you are in your house or apartment. In this day and age, there is a pretty good chance that you have a Wi-Fi router that acts as your de facto home network. It is the hub of all things connected in your home. The router is the hub, the trunk of the tree with many branches. Those branches can’t really interact with each other except through by going back through the router.
That router hub is essentially the gateway to connectivity, called a wireless access point (WAP). What Wi-Fi Direct does is cut out the trunk of the network. Instead of going back to the hub, two devices using Wi-Fi Direct are given limited wireless access points. The setup for Wireless Direct is much simpler than adding a device to a traditional Wi-Fi network, often taking only the tap of a button or entering a personal identification number or code that is entered once. In this way, Wi-Fi Direct works much like Bluetooth, just with a longer range and more stability.
For instance, if I want to hook my PC, laptop, tablet or smartphone to a Wi-Fi Direct-enabled printer, I just have to click a button once the printer, tell it to find a device (my PC, for instance) and tell it to connect. On the computer, a dialog box will pop up in the printer application and I can enable the connection.
Wi-Fi Direct does this by creating a connection between two devices using a protocol called Wi-Fi Protected Setup (WPS). The Wi-Fi Protected Setup standard is what makes connecting the devices much simpler than adding devices to a traditional wireless access point. WPS was originally created for users to easily set up security for their Wi-Fi networks without being wireless security wizards. Additional protocols have been created to make Wi-Fi Direct more useful such as Universal Plug And Play, Zero Configuration Networking and Devices Profile for Web Services.
What Wi-Fi Direct does is use software within those devices that can perform a variety of functions both simple and complex (a wireless mouse being simple, a smartphone that can share its hotspot, share streaming media and files being complex). This is done through a concept called “software access points” (Soft AP). The Soft AP makes it possible for a device to act both as the both the access point that the Wi-Fi comes from and the client that uses it.
