What is wifi direct. Wi-Fi Direct what is it? Access point. Initially, it included such organizations

Most likely, you use Wi-Fi every day at home or in a cafe, this technology is used by many people, or Bluetooth (sometimes just a necessary type of connection for a couple of devices). But what if you take the best of them and combine them? It turns out that this is implemented in Wi-Fi Direct. This article will explain what Wi-fi Direct is and how this technology works.

From Wi-Fi to Wi-Fi Direct

Most likely, everyone already knows what Wi-Fi is, if not technical aspects, then at a subconscious level for sure. This wireless communication technology has a wide range of applications, but the most used is Internet access.

Everyday use of Wi-Fi consists of connecting to a router to access the Internet. The router is a physical device that creates an access point, the existence of which can be verified in your smartphone or computer in the list of available connections. When connecting to the network, you need to enter a password and everything is ready, access to the network has been received.

From the history of Wi-Fi Direct

Wireless data transmission of nearby devices, without the use of third-party equipment, is not a novelty for a long time. One of the first and widespread solutions was the introduction of Bluetooth, which appeared in 1998. Bluetooth is a wireless communication standard for connecting peripherals to a computer (wireless mice and keyboards) or telephone (headsets). Such devices do not require fast data transfer. Bluetooth is not a high-speed communication technology by today's standards, and there are connection problems too. Read what Bluetooth is and how it works.

The difference between Wi-Fi and Bluetooth is that this connection is faster and easier to set up. It is because of these qualities that Wi-Fi consists of Wi-Fi Direct - a technology for fast and wireless communication and file transfer between various devices.

The first major company to use Wi-Fi Direct was Intel. The new standard was introduced by them in 2008 in the Centrino 2 platform. Two years later, in October 2010, major players in the network industry market: Marvell, Atheros, Broadcom, Ralink and Realtek, began to release their products. It is quite possible that a Wi-Fi adapter from one of these manufacturers is installed on your computer.

Google's Android OS product received direct support for Wi-Fi Direct from version 4.0, and Xbox one in 2013. The Windows family has supported the standard since Windows 8 on PC.

Wi-Fi Direct, how does it work?

The main idea in the development of Wi-Fi Direct was the ease of setup, the possibility of its support by all types of devices at a data transfer rate equal to the usual Wi-Fi.

It works quite simply: one device is detected by another, in exactly the same way as it detected a wireless network, it connects and the devices are connected. There is no need to adjust visibility, use long numbers, or put up with f issues. Another advantage is the need to support Wi-Fi Direct only one of the connected devices.

When connecting two devices using Wi-Fi Direct, one of them creates an access point, like a router, and the other device connects to it. Features depend on the connected device: you can print to a wireless printer, the photo frame can receive and use photos, send files from your computer to your phone, or play music and movies on your TV. Often, an Android device is used to distribute mobile Internet to other devices, but it will not work to connect to a Wi-Fi network at the same time, because the device is already used as an access point. A positive feature of Wi-Fi Direct is the absence of passwords, the connection is encrypted by WPS (Wi-Fi Protected Setup).

Now you know what Wi-Fi Direct is, and thanks to its easy installation, long range and high data transfer rate, Wi-Fi Direct has an advantage over Bluetooth in wireless data transmission. Perhaps in the future, Wi-Fi Direct will be able to replace Bluetooth, because it simultaneously eliminates both the extra standard and the hardware inside the device. This technology is newer, and replacing one standard with another can take quite a long time.

In this article, we will tell you how to connect your phone to a Sony Bravia TV via Wifi, how to duplicate the display, as well as about the Wi-Fi Direct and Miracast technologies themselves. Modern Sony TVs have many useful options that significantly expand their functionality. This is the ability to display images from smartphones "over the air", without the need for wires - watch photos, videos, listen to music on a large scoreboard, use your smartphone as a remote control and much more. But in order to take full advantage of these functions, it is important to make the right settings.

How to connect your phone to a Sony Bravia TV via Wifi is described in the instruction manual. But, despite the detailed manual, many users encounter various difficulties during the installation process. For example, how to act if the smartphone is controlled not by Android, but by iOS, or what to do if the phone does not have Direct, where can I find the access code from WiF-i in TV, or why did everything follow the instructions, but nothing happens? These questions will also be discussed in this article.

About technologies

Wi-Fi-Direct is an option that allows you to combine mobile gadgets and TV into a single network over the air, bypassing a wired connection via a LAN or the World Wide Web. For their docking, there is no need to use additional equipment and consumables (such as routers, modems, cables, signal splitters and other telecommunications equipment). In this case, the channel bandwidth is identical to the bandwidth of 802.11 devices. In other words, the data exchange rate is the same as when using regular Wi-Fi.

Miracast is a new standard for wireless video transmission. It is based on Direct, but in comparison with it, the technology under consideration has a number of improvements and differences. When creating Miracast, the developers sought to simplify the process of organizing communication as much as possible. And they succeeded very well. Any owner of a smartphone, tablet, laptop and any other Miracast-enabled mobile gadget can play games on a tablet or smartphone and display an image on a large screen, display photos, multimedia content. The TV will display everything that happens on the display of the gadget. And all this "over the air", without wires and with just a few touches.

Surely, many are interested in learning about technology such as Wi-Fi Direct, namely how it works and where this concept is used today.

Definition

Wi-Fi Direct is a feature of Wi-Fi, a standard that allows devices to connect easily.

With this technology, Wi-Fi becomes a way to communicate wirelessly, similar to Bluetooth.

Due to the fact that the technology can be present in almost every device (for example, in a smartphone, camera, printer, PC, etc.), it simplifies the work of many people, since nothing is easier than connecting devices or transferring files via Direct.

Products that have the technology can connect to each other without being connected to a home or office network or other hotspot.

Devices can establish a one-to-one connection, or a group of several devices that can connect at the same time. A set of additional services allows devices to send files, print documents, play media files, and display screens between devices. This technology contributes to the innovative possibilities of developing new applications using direct device connections.

Wi-Fi Direct enabled devices can be used for all kinds of applications - sharing files, syncing data, chatting, playing games, playing audio and video, and more. - in other words, almost everything you do with your devices over Wi-Fi is only easier and without the worries of detecting an Internet connection.

Devices with the technology can create connections with almost any device you have.

You only need one Wi-Fi Direct enabled device to create a connection.

You can connect devices anywhere and anytime, even if you don't have access to a Wi-Fi network. Devices send a signal to other devices around them, letting them know that a connection can be made. Users can view available devices and request a connection or receive an invitation to connect to another device.

Where is used

There are quite a lot of devices where Wi-Fi Direct is available.

Here are just a few of them:

  • smartphones and tablets;
  • printers;
  • cameras;
  • televisions;
  • players;
  • computers;
  • keyboards, mice and other peripherals.

This technology has become very widespread due to its ease of use. Even a novice user has the opportunity to use it. Now, for example, we will look at how Wi-Fi Direct is configured on a smartphone.

A bit of history

The standard we are considering was developed by WECA several years ago. This company is actively engaged in all kinds of technologies related to Wi-Fi.

After developing a full-fledged standard that allows you to transfer the Internet over the air, creating a technology for transferring data between devices was a completely logical step.

To do this, it was necessary to come up with something that would allow using Wi-Fi without routers and routers.

Therefore, they came up with a chip that fits inside a smartphone, tablet or other device. It is, in fact, a mini-router.

In general, WECA is an alliance of the largest manufacturers of Wi-Fi equipment.

Initially, it included such organizations:

  • 3com;
  • Cisco, then called Aironet;
  • Intersil (aka Harris Semiconductor);
  • Agere (aka Lucent);
  • Nokia;
  • Symbol Technologies.

Most of them belong to the alliance today. They support all developments, including the development of Direct.

On Android

To use this technology on an Android phone, you need to do this:

  • Open Wi-Fi settings. Usually in the settings there is a corresponding menu item for this. Turn on Wi-Fi using the switch.
  • At the top right there will be a button called "Wi-Fi Direct". Tap on her. Actually, the presence of this button allows you to determine whether this function is available on your smartphone at all. If it is not there, you can look in other sections of the settings, but, most likely, the function is simply not there.
  • For data transfer do the same on another device Where are you going to send something?
  • Now go to the file manager (the program where you see your files and folders). Go to the functions of the file you want to transfer. To do this, sometimes you just need to hold it down or hold it to highlight, and then click on the button in the form of three dots. There will be an item "Send via". Live on it.
  • Next, you will be asked which way you want to perform this action. Among all the methods, find "Wi-Fi Direct".
  • Select the device to transfer data to. A prompt will appear on the other device and the user must accept it.

In fact, the method of use is exactly the same as in Bluetooth. This technology has been known for a very long time and many have used it. Surely you too. Therefore, you can easily figure out how to use Direct.

If something doesn't work

Many users will not be able to complete the steps described above for the simple reason that their device does not have Direct.

In general, this function can be present thanks to the chip, just like Bluetooth.

If it is not in a smartphone, laptop or somewhere else, then it is simply impossible to configure the function.

You know what Wi-Fi technology is and use it daily. You know what Bluetooth is and use it quite often. The strengths of these two technologies can be depleted and this is called Wi-Fi Direct.

You can use Wi-Fi Direct on a TV only if it is a smart TV and it even has Wi-Fi, this does not mean that you can turn on Wi-Fi Direct - this feature may simply be absent. So the samsung ue55ju6600uxua TV has it, but the Philips 40PFS5709 does not, although both have Wifi.

You can connect on a samsung, sony, hp computer or laptop with Microsoft windows 10, windows 7 or windows 8.1 installed if they support Intel WiDi, via Windows Media or a virtual WI-Fi Direct adapter from Microsoft.

WiFi is fast. Therefore, WiFi Direct technology has been adopted to quickly transfer data between two devices, and it is even much easier to turn it on, configure and use it and can be used for wireless connection.

The first company to introduce WiFi Direct support was Intel: they introduced the first standard, the Centrino 2 platform, in 2008.

Then, two years later, several major players in the networking industry followed suit, such as Marvell, Atheros, Broadcom, Realtek Ralind. It is possible that your laptop's Wi-Fi is from one of these manufacturers.

Google also added support for WiFi Direct on Android 4.0. Blackberry OS received an update to version 10.2, and the first to support WiFi Direct Xbox was the Xbox One, launched in 2013.

Note: Some people confuse WiFi Direct with Ad-Hoc wireless connections.

This connection connects two computers using WiFi, but its speed is limited to 11 Mbps.

How WiFi Direct works

The most important principles that underlie the WiFi Direct standard are very simple. The mode of operation is as follows: the device detects another, as if opening a wireless network. Then enter the password or press the button and you're done, the equipment is connected.

There is no need to set visibility, just enter a numeric key, just like with Bluetooth technology.

In addition, only one of the two connected devices must support Wi-Fi Direct.

To connect two devices via Wi-Fi Direct, one must create an access point like a router, and the other device connects to this access point. This process happens automatically, there is no need to do anything manually.

You can print to a wireless printer and send photos from your phone to your computer, or play music on your TV from your tablet or smartphone.


With this, you can forget about passwords. WiFi Direct technology uses Protected Setup (WPS), which is an easy way to connect two devices using secure wifi.

As with modern routers, simply enter the number displayed on the screen or press the connect button.

With a simplified configuration and faster speeds, WiFi Direct is a much better option than Bluetooth when it comes to transferring files between two or more devices.

Advantages in terms of ease of installation and scope of application, the sea is a useful standard for connecting peripherals.

Some analysts are even predicting the end of the Bluetooth era, even though the technology is new enough that it could be years from now. If you have any questions please use the comments section below. Good luck.

Wi-Fi Direct technology - what is it? This is a state-of-the-art set of software protocols that allows you to transfer files without an internet connection. Devices that support this certificate can connect to each other and send data over a distance of up to 200 meters. The transfer speed reaches high rates - up to 250 megabits per second. It is also worth noting that this network has a high channel security. Wi-Fi Direct technology is very similar to the well-known Bluetooth standard, but it surpasses it in many ways.

The specified method of data transfer greatly simplifies the work of users.

Progress does not stand still, and today you have the opportunity to perform unimaginable operations that you could only dream of before: print files directly from your phone, watch videos from your tablet on your TV screen, send photos from your smartphone to your laptop, share data on your computer openly through TV. And all this without wires, waiting times and multi-step setup.

Features of wireless technology

  1. This set of protocols is developed, certified and maintained by the Wi-Fi Alliance.
  2. After enabling the specified function on the devices, they automatically discover each other.
  3. You don't need a router to create a Direct network. A router can come in handy if you want to access the World Wide Web.
  4. You can create a "1 - 1" or "1 - Many" gadget connection. Paired devices include smartphones, laptops, computers, printers, keyboards, VCRs, routers, scanners, cameras, digital frames, and more.
