Wi-Fi Direct, what is it and what is it for

Wi-Fi Direct is a new system of connection between multiple devices that does not require the intermediation of a wireless router, here's how it works

More and more devices are starting to use Wi-Fi Direct. This term refers to a specific technology that allows two different devices to establish a direct, peer-to-peer Wi-Fi connection without the need for a wireless router.

In practice, with Wi-Fi Direct we'll be able to connect two smartphones to each other a bit like we do with Bluetooth, that is, without the need to use other devices. Wi-Fi Direct gives mobile devices an easy way to communicate with each other using standard Wi-Fi protocols. Compared to the classic router, it is much easier to use because it doesn't require installation and we won't have to enter any password to connect, since the connection with Wi-Fi Direct happens automatically. In addition to smartphones, some peripherals, such as mice and keyboards, can also communicate via Wi-Fi Direct.

Other uses of Wi-Fi Direct

Wi-Fi Direct can be used to remotely connect to a printer without it having to be part of an existing wireless network. There is support for Wi-Fi Direct apps on Android, although it must be said that very few programs have adopted it at the moment.

How it works

Wi-Fi Direct uses the same technology as "standard" Wi-Fi. Simply, it can also work as an access point so that other Wi-Fi equipped devices can connect. This is a feature already seen with technology called Wi-Fi Ad-hoc, only with Wi-Fi Direct there is no need for difficult synchronization and installation to use the service. Locating another Wi-Fi Direct device nearby is very easy, just check the list automatically created by the device. The big doubt about Wi-Fi Direct is its security. As we said, in fact, there are no PINs or passwords and users must hope that manufacturers use adequate security standards, such as the WPS connection method. While at the moment the encryption system used is WPA2.
