Connection via wi-fi direct. What is Wi-Fi Direct and how does it work? How to connect PC to TV via Wi-Fi Direct

The computerization of everyday life has introduced the technical terms Wi-Fi and Bluetooth into everyday life. Now even people who are far from computer technology have an idea about devices that support Wi-Fi and Bluetooth. With their help, several devices are connected to the Internet and data is exchanged wirelessly.

Today we will talk about one of these technologies.

What is WiFi Direct?

Wi-Fi Direct combines the advantages of Wi-Fi and Bluetooth. Wi-Fi wireless technology, which is mostly used to access the Internet, is, unlike Bluetooth, high-speed. Another advantage is that it is easier to set up. Wi-Fi Direct, unlike Wi-Fi, does not specialize in Internet access, but in wireless data transfer between devices without a router. The number of such devices is not necessarily limited to two in most cases. Note that you cannot use a Wi-Fi Direct hotspot and a Wi-Fi network at the same time.

Wi-Fi Direct transfers data much faster than Bluetooth. When connecting via Wi-Fi Direct, unlike Bluetooth, you do not need to think about finding the connected device in the visibility zone. The established connection is encrypted according to the Wi-Fi Protected Setup standard and does not require password protection.

Support for one or another Wi-Fi Direct device is physically implemented by the presence of a special chip in it. Because the technology is new, this chip is only found in smart TVs and the latest smartphones and tablets. Windows operating system supports Wi-Fi Direct from version 8, and Google Android OS from version 4.0.

Connecting the TV to a mobile device via Wi-Fi Direct

Such a connection is convenient, for example, for transferring and viewing video files from a smartphone or tablet on the TV. Another option is remote control of the TV. Obviously, the devices to be connected must support Wi-Fi Direct. The connection establishment initiator sends a communication invitation to the selected device from the list of discovered ones. It remains to confirm the connection. As a rule, mains-operated or stationary devices are selected as the "master" device.

As an example, let's take a look at the specific steps to establish a connection between an LG Smart TV and an HTC One V smartphone.

In the "Wireless connections and networks" section of the smartphone settings, click the "More" button.
In the Wi-Fi Direct tab that appears, click OK. The message "Wi-Fi Direct is enabled" should appear.
In the TV settings, go to the "Network" tab.
Select Wi-Fi Direct from the list of networks that appears.
In the pop-up window, turn the switch to the "On" position.
After detecting the Android device, answer "Yes" to the "Request connection" question. In the same window, check the box next to "Connect automatically without prompting" to speed up subsequent connections.
Once your phone is connected, it will prompt you to press OK to accept the request from the TV. After such a press, a message will appear on the TV about establishing a connection with the Android device.

As you can see, setting up a connection via Wi-Fi Direct is very simple and available to any user.

Application and prospects of Wi-Fi Direct

Using Wi-Fi Direct technology, it is convenient to transfer files from a computer to a smartphone, watch videos and play music on a TV. It is expected that this interface will be equipped not only with laptops, tablets and smartphones, but also with printers, mice, headsets, digital and video cameras, game consoles.

Fans of Wi-Fi Direct predict the complete displacement of Bluetooth in the near future. Yes, wireless data transmission using this technology is significantly superior to Bluetooth in terms of speed, range and ease of deployment. But Wi-Fi Direct is not without its drawbacks. These include high power consumption, which can quickly drain a smartphone. True, recently there has been a development of energy-saving modes for use specifically in Wi-Fi Direct.

Another disadvantage is the potential for mutual interference with extensive use of Wi-Fi Direct in an apartment building. From this point of view, it is much more comfortable to use this technology in a country house or country house.

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.

Supported by Windows 7, Windows 8, Windows 8.1, Windows 10 and Android platform.
Devices with a platform below Android 4.0 do not contain this function.
Only those devices that have a special chip will be able to join this function. Most vehicles with a year of manufacture not earlier than 2015 contain this chip. Developers of global tech brands have announced that in 2016 all smartphones will be able to connect wirelessly and support the DLNA function.
The devices communicate with each other thanks to a peer-to-peer wireless connection “Ad-hoc”.
After the first successful attempt to communicate devices over the Direct network, this process can be repeated where and when convenient.

To prevent unauthorized intrusion into your network, the technology includes the Wi-Fi Protected Setup application.

How to establish a direct network connection

There are two simple ways to connect equipment to each other:

By turning on the Wi-Fi Direct function in the network settings of one device, then another. Devices will find each other and start exchanging data.
After the gadgets find each other, they will request a special PIN code to confirm the operation. One device automatically generates this code, and on the other, the user enters it.

Programs to enable new Wi-Fi Direct features

Having established the connection in one of the two methods proposed above, you will need a special program to carry out the desired operation. There are 4 services developed by the builder:

The wireless network itself allows devices to send messages and attachments, for example, you can send a video from a tablet.
Miracast allows you to view videos, photos, presentations and play games on large TV screens. Setting up this feature on Windows 10 and 8 is easy, since Miracast is built into them: Devices-Projector-Add a wireless display. On Windows 7, it is hardly possible to enable the specified service; it is easier to use an HDMI cable for connection.

DLNA service for viewing files from one device on another. With this program, you can connect a PC on Windows 7, 8 or 10 to a TV, open access to files and set up a special utility for such a connection on the TV.

Wi-Fi Direct Print allows you to print files that are on your smartphone, tablet or any other gadget.

After connecting the Direct function, the device itself determines the compatible equipment and its software to carry out the necessary operations. For example, if you want to play videos from your tablet on your TV, you'll need Miracast pre-installed. In the search, your device will display gadgets supported by this service.

Today we got acquainted with such a set of software protocols as Wi-Fi Direct. This certificate has great prospects, since it eliminates the need to work with a router. Once connected devices using a wireless network, you can transfer data and receive files anywhere and anytime without an Internet connection. Do not lag behind technological progress a single step and then you will gain new opportunities for a bright and interesting life.
