What is direct WiFi?
In recent years, manufacturers have been touting the availability of direct WiFi as a wireless communication technology on their mobile devices (smartphones, tablets and more ...). But do you know what exactly it is? What is the difference between direct WiFi and WiFi?
Definition
To begin, you should know that the direct Wifi is a wireless communication technology or bluetooth audio transmitter that allows you to connect devices together without cables. So far, nothing very new compared to other technologies such as Bluetooth for example. On the other hand, it should be noted that apart from the fact of being able to exchange data, WiFi Direct makes it possible to connect two devices, for example a Smartphone and a TV, in order to display the data stored on the Smartphone to the screen. television, or several devices on the same device as is the case with printers, keyboard or mouse connected to a compatible computer among others, and this via the WiFi connection.

What sets conventional WiFi apart from direct WiFi is the fact that it is no longer useful to use a router for both devices to connect, which further facilitates the connection between the two devices. Yes, but why not just use Bluetooth? First of all, be aware that anything that can be transmitted through the conventional WiFi network can also be transmitted via direct WiFi . Examples include sharing photos, printing documents from your phone to a printer, and so on. You can see on the video below the operation of this technology. |
As a result, you are certainly wondering what is the point of having direct WiFi if you already have the Bluetooth or NFC connection? Everything is really a matter of practice. The NFC needs other equipment to work well, and the distance is very limited. Bluetooth for its part often does not need anything to communicate two compatible devices, but its ability is limited, and the distance is also limited. For its part, the WiFi direct allows to transfer data over a very large distance, and if a router is installed, this distance can be increased, and especially it will be possible to transfer large files through the direct Wifi.
To conclude, I will say that with NFC, Bluetooth, wireless charging, WiFi direct, we can imagine that the cables will soon be obsolete.
