A new wi-fi connection.

Remember when there was no possibility of a Wi-Fi in coffee chains or large airports or hotels popular? There will ever look the whole day without finding one?

Now, Wi-Fi is everywhere. An estimated half a billion users around the world using Wi-Fi for about 2 billion devices, according to the Wi-Fi Alliance in Austin, Texas, which certifies and promotes the technology standard Wi-Fi.

Yet for all its utility, Wi-Fi is almost too common. Applications and resources such as printers on a network that are open to all, even if you want to share with few. Public hotspots to give you the feeling of swimming in the pool at the end of the day: you're taking a bath together with people with whom would not have shared the elevator. Office hot spots are the same: Would you skinny-dip with every employee and guest office?

Wi-Fi has lacked a point-to-point to allow the direct connection between Wi-Fi for the specific peer-to-peer and controlled access to resources. But before the end of the P2P Wi-Fi could be a reality.

Wi-Fi Alliance is now working on Wi-Fi Directive, which allows users to Wi-Fi to connect to each other without having to dip into the public pool.
