We all know that a traditional Wi-Fi network is based on the presence of a wireless access point or a router and these access points basically perform three functions: physical support for wireless and wired networking, routing between devices on the network, and adding and removing devices from the network. But what would you say if one told you about a technology, a Wi-Fi technology, which does not require any router or AP, you would get pleasantly surprised. That is what the new age technology called Wi-Fi direct is all about.
Wi-Fi direct is a standard, which has been developed by Wi-Fi Alliance. The standard allows two or more devices to interact directly without the presence of wireless access points or routers. The said devices can then perform several tasks such as printing, syncing, share files and many more. With Wi-Fi direct enabled devices you can play games with your partner without the physical connection between the two devices of yours. And when I say devices they could be anything from smartphones to laptops to cameras to printers to projectors to TVs.
But one has to keep this fact in mind that the Wi-Fi direct has not been developed with the intention of replacing the existing standard because the Wi-Fi direct has its own set of bottlenecks such as it is not as secure as the normal standard, then it is a little difficult to control and regulate.
The main function of Wi-Fi direct is mobile sharing with less effort. Let us take an example: if we have to display some of the pics that is on our mobile phone to our Wi-Fi direct enabled TV, with the help of the said standard we can do the same without getting involved in the quagmire of passwords and establishing connection, which we need in the older standard.
