What is wi

Get connectivity between mobile phones, tablets and TV without the need for Internet and safely. Sounds ideal, but is that possible? Wi-Fi Direct technology is starting to catch on, but many people still don't know how useful it is. To clarify and make the technology for you, in this article we explain everything about this new way of connecting devices.

How does Wi-Fi Direct work?

All portable computers, capable of establishing a wireless connection, with a regulator and an antenna. In theory, it would be easy to create networks between these devices. The protocol so that they "communicate" to each other. This reasoning is what is behind a technology known as Wi-Fi Direct, increasingly common in everything that uses the wireless interface .

Wi-Fi Direct is a connection system between devices that dispenses with the use of a router. Suppose you have a smartphone and a TV with this system. This means that you can connect one device to another without using the router. With that, it is easier to distribute content from one device to another.

On paper, the idea is that Wi-Fi Direct also allows you to discover all the technology support devices in the region. Corresponds to the option of the user for whom you want to connect.

But isn't that the same as Bluetooth does?

Yes, the idea is the same. But this technology is much faster and more secure, given the levels of data encryption that wireless interfaces, such as WPS and WPA2, support.

Does Wi-Fi Direct replace the router?

This pattern was developed to support tasks that are not dependent on the Internet. Suppose you want to print a file that is on your mobile. If your smartphone and printer have Wi-Fi Direct, you can simply send the file wirelessly to the printer. You don't need cables or internet.

You can also share the Wi-Fi Direct network, but this technology is best used in situations where the user shares data over a network directly.

How does Wi-Fi Direct work?

Wi-Fi Direct uses two functions to assign surroundings: direct device discovery and discovery service. The first clues the area where you are to find the devices that have Wi-Fi Direct, listing those so that the user chooses the one they want to connect to. Service Discovery lists services in the area, such as printers and televisions.

The Wi-Fi Alliance, a global entity that brings together manufacturers and developers of standardization and development of wireless interfaces, created this technology that is backward compatible. In other words, even older devices will have the ability to participate in this decentralized network.

Furthermore, the application of this technology by manufacturers should not add manufacturing costs, since the protocol uses the conventional hardware of any Wi-Fi system: controller chips and antennas.

Wi-Fi Direct between different platforms

This technology is part of the global agreement, which governs DLNA, the set of technical standards that establish guidelines for the operation of interfaces that aim to connect different devices and operating systems. So, in theory, Wi-Fi Direct should be able to connect your iPhone to LG TV and your Xbox 360, for example. However, the standard continues to grow in popularity, so connectivity won't always be that simple.
