What is Wi-Fi direct technology - how to use it. Connecting phone to TV via wifi direct

How to use Wi-Fi Direct on Android is a very common question. The fact is that new technologies are constantly appearing in the world that make it possible to simplify people's lives. One of them is Wi-Fi Direct. Since this is a relatively new technology, few people know how to use it and what it is for.

What is Wi-Fi Direct

This is a new standard for wireless communication that allows information to be transferred between multiple devices that support this technology. It is worth noting that you do not need an access point (router) to connect and transfer data. In other words, you can connect two or more devices directly. For example, you can connect two Android phones over Wi-Fi if they support this technology.

It should be noted that this function is supported by almost every modern tablet and smartphone with Android OS. Of course, if we are talking about a budget gadget, then such functions may be absent.

And you don't need to configure anything.

Devices detect each other automatically. In addition to the gadgets we are used to, such as laptops, smartphones, tablets and so on, using Wi-Fi Direct, you can also connect printers, scanners, Smart TVs, digital photo frames, DVD players, etc.

The main thing is that the device is equipped with this function.

Now you know what is Wi-Fi Direct on Android phone. Now you can move on to the question of how this standard works.

How technology works

It should be noted right away that the data transfer rate with a direct connection can reach 200-250 Mbps. At the same time, the range of action with a line of sight is 200 meters and about 50-100 meters in buildings. Also, the level of security of such a communication channel deserves special attention.

To work with this standard, the device must be equipped with an appropriate chip. They are of several types:

• Work in the 2.4 GHz band.
• In the 5 GHz band.
• Working in both bands.

Wi-Fi Direct on Android has some pretty useful features. For example, Device Discovery and Service Discovery. They allow smartphones and tablets (and other devices) to find each other and create a network with each other. In this case, everything happens without your participation.

Moreover, these functions allow you to get information about the capabilities of each gadget on the network. For example, when you want to transfer a video from your tablet to another device, only those that can receive and play this file will be displayed in the list of connected devices.

The developers claim that this standard creates a fairly secure communication channel. However, in fact, this is not the case. As long as we are talking about home use, there is no threat to personal data. But this is not the case if you use this feature in the office. Many users can join the network here. Any Wi-Fi Direct for Windows can act as a proxy, and such a computer will receive all information about any device on the network.

Setting up Wi-Fi Direct on Android devices

To set up Wi-Fi Direct on Android, enter the Wi-Fi wireless settings and turn on the adapter.

You will automatically be taken to the page for finding devices that also support this function. It should be noted that it must also be enabled on other gadgets.

Once your smartphone finds the connection you want, just select it and confirm the connection. Further, the devices will be combined into one network (like Bluetooth). Now you can transfer files or stream sound and picture to other devices. You don't need to configure anything else.

How to transfer files from an Android tablet using Wi-Fi Direct

First, enable this function on the sending and receiving device and connect them as described above. Then open the file manager on the sending device and find the file you want.

Hold your finger on it until a menu appears. Select Send Via. Then select the appropriate option (in our case, it's Wi-Fi Direct).

As you can see, everything is very simple and straightforward. Absolutely everyone can handle this. At the same time, as mentioned above, every modern Android tablet supports Wi-Fi Direct technology.

There is a Wi-Fi Direct application for Android - installing such a program will make using the new communication standard on your phone or tablet easier and more convenient.

In addition to simple data transmission, users can also connect devices such as printers, televisions, audio systems, and so on via this standard. It is important that these devices are equipped with an appropriate chip.

Disadvantages of Wi-Fi Direct

Like any other technology, this wireless communication standard has its drawbacks:

• Clogging the ether... The fact is that when organizing a regular network, all gadgets are connected to one access point. But in the case of Wi-Fi Direct, many separate connections are created. Moreover, participants can be both people (users of tablets, smartphones, laptops, and so on) and gadgets - printers, scanners, televisions, etc. As a result, one multi-storey building can have several tens or even hundreds of networks. Because of this, a real mess is created on the air. At the same time, the networks cannot be controlled. This, in turn, is reflected in the data transfer rate.
• As mentioned above, weak level of protection when it comes to connection in office and public buildings.
• Energy intensity... On the one hand, this feature is very useful and allows you to transfer large files at high speeds. This essentially reduces the time required to transfer information. But this speed requires significant energy consumption.

And given how much this will affect the autonomy of the gadget, it should be understood that you should not get carried away with this function. Smartphones and tablets run out pretty quickly anyway. It should be noted that Bluetooth consumes much less power.

• Long range... It would seem that this is an advantage. On the one hand, it is. On the other hand, cybercriminals can take advantage of this. In addition, given that in this way we litter the air, such a range becomes more negative than a positive quality.
• And finally, it is worth remembering that to use this function Corresponding chip required... Of course, modern phones are equipped with both adapters (Wi-Fi and Wi-Di). But there are still quite a few devices that do not support this technology.

So now you know how to connect Android to Android via Wi-Fi directly. Despite the existing shortcomings, this connection is still widespread. And although it will not supplant Bluetooth, its useful features simplify some tasks.

A couple of years ago, in order to connect a TV or any other gadget to a computer, it was required to find a suitable cable and perform a bunch of settings. This is not the case today. It is enough to have a modern device that supports Wi-Fi Direct and perform a few settings. Therefore, we will consider the current topic on how to enable Wi-Fi Direct on Windows 10 and connect various devices to the system.

What is Wi-Fi Direct?

Wi-Fi Direct is a modern wireless network standard that allows information to be transferred between multiple devices that support this technology. At the same time, to pair the devices, you only need a router, or rather an access point. No adapters or cables needed. The devices find each other on their own.

Today, this function is supported by almost all PCs, laptops, smartphones, tablets and even cameras, printers and other devices.

However, it is necessary to immediately note several features in the operation of this function:

• The data transfer speed with a direct connection can reach 200-250 Mbps, and the range will reach 50-100 meters.
• To work with the Wi-Fi Direct function, the gadget must have a chip. There are several types of this chip: functioning in the 2.4 GHz and 5 GHz bands. There are also devices, however, they are not from the budget, which support operation in both ranges.
• When creating a connection for several devices via Wi-Fi Direct in the office, you need to understand that when you connect a third-party device, data transmission security is not guaranteed. Therefore, this function is recommended to be used at home and only with password-protected Wi-Fi.

Therefore, if your device has this function and you want to connect another gadget to it, it is worth making a few simple settings, which we will now describe.

How do I set up Wi-Fi Direct on my phone?

In order to use the Direct function on your phone, you should do the following:

• Turn on Wi-Fi in the device settings.
• As soon as you activate Wi-Fi, the Direct function appears in the menu. We twist on it to open it.

• We start the search for devices.

• As soon as a new gadget is found, you should select it and confirm the connection.
• To transfer materials to the second device, you should find the file and select "Send via ..." and specify Wi-Fi Direct.

In this way, multiple devices that support the Wi-Fi Direct function can be connected. However, it is important to remember that due to different versions of Android firmware, the step-by-step steps may differ from those presented.

How do I connect my PC to a TV using Wi-Fi Direct?

The way how to connect a computer to a TV, or vice versa, will be different from the above.

• Using the instructions supplied with the LG or Samsung TV, we connect the device to the same router as the PC.
• Now we set up a DLNA server on a laptop or stationary PC. To do this, in the Explorer in the menu on the left, select "Network". A notification appears stating that "Network discovery and file sharing are disabled." Click on this message with the right mouse button and select "Turn on network discovery and file sharing."

• A message will appear. One must choose to create a private network.

• After that, a list of all devices connected to this network will appear in Explorer.

• After DLNA is activated, you need to go to the menu of your TV to view the contents of the connected devices. For example, on LG TVs, you need to select the "SmartShare" section. It will display the contents of folders allowed for viewing in Windows 10.
• Further, to start a movie on your LG TV, you need to right-click on it and select "Play on ..." and select the device model that will be displayed in the list.

This is the standard Direct configuration instruction. In the manual for each TV model, there is a section on Direct. You can use the advice of the TV designers.

For more information on how to connect Android to an LG TV, see the video:

If you do not yet have an access point (router) at home, but you have already acquired a modern TV with the Smart TV function and want to connect your smartphone or tablet to it, then you can use Wi-Fi Direct technology, which allows you to connect devices directly.

In this article I will try to write in detail about how to establish connections between two devices using the "Direct" technology. I will show on the example of an NTS smartphone on Android OS and an LG TV (32LN575U).

If we talk about why they should be connected, then there are several options. For example, to control a TV from your phone using LG's proprietary technology called TV Remote. I have already written about this technology and how to set everything up. Or to transfer media content from a smartphone to a TV, using DLNA technology (I will write about this later).

We need:

• Smartphone or tablet with Wi-Fi Direct support. You can look in the settings, where the management of Wi-Fi networks, etc.
• Wi-Fi Direct TV. You can find out about this in the specifications, call the manufacturer's support, or look in the settings.

Turn on Direct on your phone

Go to the settings and in the section "Wireless Connections and Networks" click on the “ More" (this is so on my HTC One V, you may call these settings differently)... Click on Wi-Fi direct, thereby enabling it. Confirm by turning on by clicking on Ok.

A message appears that the feature is enabled.

Okay, let's go to TV.

Launch Wi-Fi Direct on TV (LG)

Go to settings (there is a special button on the remote for this) and go to the tab Net... Then select the item "Wi-Fi Direct".

Wi-Fi Direct technology - what is it? It is a state-of-the-art suite of software protocols that allows you to transfer files without an internet connection. Devices supporting this certificate can connect to each other and send data up to 200 meters away. The transmission 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 unthinkable operations that you could only dream of before: print files directly from your phone, watch videos from your tablet on the TV screen, send photos from your smartphone to your laptop, openly use data on your computer through the TV. And all this without wires, waiting times and multi-stage settings.

Features of wireless technology

1. This set of protocols is developed, certified and supported by the Wi-Fi Alliance.
2. After enabling the specified function on the devices, they will automatically detect 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. The devices to be paired include smartphones, laptops, computers, printers, keyboards, VCRs, routers, scanners, cameras, digital frames and other equipment.

1. Supported by Windows 7, Windows 8, Windows 8.1, Windows 10 systems and Android platform.
2. Devices with platforms below Android 4.0 do not include this feature.
3. Only those devices that have a special chip can join this function. Most equipment, with a year of release not earlier than 2015, contains this chip. Developers of global tech brands have announced that in 2016 all smartphones will be able to connect wirelessly and support DLNA function.
4. Devices communicate with each other thanks to a peer-to-peer wireless connection "Ad-hoc".
5. After the first successful attempt to connect devices over the Direct network, this process can be repeated where and when it is convenient.

1. 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:

1. Turning on Wi-Fi Direct in the network settings of one device, then the other. The devices will find each other and start exchanging data.
2. After the gadgets find each other, they will ask for a special PIN to confirm the operation. One device automatically generates this code, and on the other it is entered by the user.

Programs to enable new Wi-Fi Direct functions

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

1. The wireless network itself allows devices to send messages and attachments, for example, you can send a video from a tablet.
2. Miracast allows you to view videos, photos, presentations and play games on large TV screens. Configuring 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.

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

1. Wi-Fi Direct Print allows you to send files from your smartphone, tablet or any other gadget to print.

After connecting the Direct function, the device automatically detects compatible equipment and its software to carry out the necessary operations. For example, if you want to play video from your tablet on your TV, you need the preinstalled Miracast software. In the search, your device will display the 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 you connect the devices using a wireless network, you can transfer data and receive files anywhere and anytime without an Internet connection. Keep up with technical progress a step and then you will gain new opportunities for a bright and interesting life.
