What does Wi-Fi Direct mean? Wi-Fi Direct: everything you need to know about the new technology

Youtube

Surely, many are interested in learning about such technology 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, a smartphone, camera, printer, PC, etc.), this simplifies the work of many people, since there is nothing easier than connecting devices or transferring files via Direct.

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

Devices can establish a connection one-to-one, or in a group of several devices that can connect simultaneously. A suite of additional services allows devices to send files, print documents, play media, and share screens between devices. This technology enables innovative development of new applications that leverage direct device connections.

Devices that support Wi-Fi Direct can be used for all types of applications - for sending files, synchronizing data, communicating, playing games, playing audio and video, etc. – in other words, almost everything you do with your devices over Wi-Fi, only easier and without the worry of detecting an Internet connection.

Devices with technology can create connections with almost every device you own.

To create a connection, you only need one Wi-Fi Direct-enabled device.

You can connect devices anywhere, anytime, even if there is no access to a Wi-Fi network. The 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 be prompted to connect to another device.

Where is it used?

There are quite a lot of devices with Wi-Fi Direct.

Here are just a few of them:

smartphones and tablets;
printers;
cameras;
TVs;
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, as an example, we will look at how Wi-Fi Direct is configured on a smartphone.

A little history

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

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

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

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

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

Initially it included the following organizations:

3Com;
Cisco, which was then called Aironet;
Intersil (aka Harris Semiconductor);
Agere (aka Lucent);
Nokia;
Symbol Technologies.

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

On Android

To use this technology on a phone with the Android operating system, you need to do this:

Open Wi-Fi settings. Usually there is a corresponding menu item for this in the settings. Turn on Wi-Fi using the switch.

At the top right there will be a button called “Wi-Fi Direct”. Tap on it. Actually, the presence of this button allows you to determine whether this function is even available on your smartphone. If it is not there, you can look in other sections of the settings, but most likely the function is simply missing.

For data transfer do the same on another device– where are you going to send something?
Now go to your 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 select it, and then click on the button in the form of three dots. There will be a “Send via” option. Live on it.

Next you will be asked exactly how you want to perform this action. Among all the methods, find “Wi-Fi Direct”.

Select the device where you will transfer data. 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 out

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

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

If it is not on your smartphone, laptop or anywhere else, then it is simply impossible to configure the function.

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 also the ability to display images from smartphones “over the air”, without the need for wires - watch photos, videos, listen to music on a large display, use your smartphone as a control panel and much more. But to take full advantage of these features, it is important to make the correct settings.

How to connect your phone to a Sony Bravia TV via Wifi is described in the operating instructions. But, despite the detailed instructions, many users encounter various difficulties during the installation process. For example, what to do if your smartphone is controlled not by Android, but by iOS, or what to do if your phone doesn’t have Direct, where can you find the access code for WiF-i on TV, or why did you follow everything according to the instructions, but nothing happens? We will also examine these questions in this article.

About technology

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. To connect them, 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 throughput is identical to the throughput of 802.11 devices. In other words, the data exchange speed 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 in question 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 perfectly. Any owner of a smartphone, tablet, laptop or any other mobile gadget with Miracast support can play games on a tablet or smartphone and display images on a large screen, display photos, and multimedia content. The TV will display everything that happens on the gadget’s display. And all this “over the air”, without wires and with just a few touches.

How to set up Wi-Fi on a Sony Bravia TV

Activating Wi-Fi.Direct on TV is easy. To do this, you need to enable the “Built in Wi-Fi” checkbox, and then Wi-Fi-Dir ect.

You can do this as follows:

Pick up the remote control, find the HOME button on it and click on it. Note! Some users are faced with the fact that after performing this action the TV freezes and nothing happens. In this case, you need to perform a power reset or reboot and then try again. If this does not help, try disconnecting all devices from the TV and performing a factory reset.
Next, you need to go to the “Advanced settings” interface. To do this, follow this path: Settings – NETWORK&ACCESSORIES – NETWORK – Advanced settings.
On the “built-in WiFi” tab Built-in.Wi-Fi, put the icon in the On field.
Also set the Wi-Fi.Direct box to On. Many users are also interested in how to find out the Wifi Direct password on a Sony Bravia TV. This can be done in the same menu in the Show Network (SSID)/Password dialog. When you click on the TV screen, a window will appear with the name of the network and the secret code. This data is subsequently entered manually when debugging the Wi-Fi of the connected mobile device. If the connection was established successfully, a notification about this will appear on the TV receiver monitor.

Now you know how to connect Wi-Fi to a Sony Bravia TV. Immediately after carrying out the steps described above, the TV goes into synchronization mode and waits for binding. Here you can also set synchronization confirmation when trying to communicate with an unfamiliar device: on the remote control, click on the “Options” button and turn on the “Registration notification” item.

How to connect an iPhone to a Sony Bravia TV via Wi-Fi

Activate Wi-Fi Direct on TV using the instructions above.
Go to your iPhone settings and select Wi.Fi, then Dir-ect-xx-BRAVIA.
In the window that opens, enter the WPA key displayed on the TV receiver display and click Join.
Wait while pairing between devices is established. This may take a few minutes.
After this, the settings window will be displayed. If there is a mark for the SSID on the iPhone side, and a dash on the Sony Bravia side, it means the docking has been established.

If the connection is not established, try again, first making sure that the password is entered correctly.

Duplicate iPhone screen on Sony Bravia TV

Unfortunately, not all game and application developers provide AirPlay support for their products, which means that not all streaming videos from applications or the Web are displayed on TV. You can get around this problem by duplicating the content from the iPhone display to the TV screen. To do this, swipe up on the display, expand Control Center, and select AirPlay, then AppleTV.

How to connect your phone to a Sony Bravia TV

Now let's look at the features of connecting devices running Android OS to Sony TV.

As with the iPhone, the first step is to go into the device settings. In it, find the WI-Fi menu and turn on the module, then click on the three dots, then on Wi-Fi-Direct.

After activating the Wi-Fi-.Direct button, the gadget will begin searching for suitable devices. It will take some time. Upon completion, you will be presented with a list of all gadgets available for communication. Select the SSID of your home theater from this list and enter Password. A request to connect a new device will appear on the TV screen. Click “Ok”. Next, the TV receiver performs synchronization and then displays a message about successful pairing.

Don’t forget that you can synchronize no more than ten external gadgets with TV via Wi-Fi Direct. To view the list of gadgets working on your home network, you need to go to the Direct debugging menu on your TV, then press the “Options” button on the remote control and select “Display list of devices.” If you want to delete any of the connections, click on the button located in the center of the remote control. The “Are you sure you want to remove from the list” dialog box will open. Using the arrows on the remote control, move to the word “Yes”, then click on the central button.

How to connect the Internet to a Sony Bravia TV via Wi-Fi if the phone does not have direct? It's simple. On the TV, go to the Wi-Fi-Direct debugging mode, press the “Options” key on the control panel and select “Manual”. In the window that opens, select “Other methods”. A window will appear on the monitor displaying the name of the network and the password required to log in. You need to find this name in the Wi-Fi settings menu of your smartphone and write Password.

How to mirror your phone screen to a Sony Bravia TV

You can install Screen Mirroring only if Miracast technology is supported by both the television receiver and the mobile device. As already noted, a characteristic feature of Miracast is the simplification of technology. And here everything is really very simple.

Depending on the Android version and smartphone model, the steps may differ slightly. In version Android 6.0, to do this, go to settings - “networks and communications” - “wireless display”. Activate the mode. The smartphone will begin searching for available equipment, after which your TV will appear in the list. Click on it - the contact will be automatically established, and an image from your mobile device will appear on the TV screen.

If the connection was not established automatically, do the following: click on the “Input” switch, which is located on the control panel, then “duplicate”, then turn on the wireless display from your smartphone.

Articles and Lifehacks

Previously, only Bluetooth was used for fast file transfer, but today technology such as Wi-Fi Direct has appeared, which is a good alternative to Bluetooth. So, what is wifi direct on a phone?

What kind of technology is this

Any person who has at least once encountered setting up Wi-Fi at home without using the default settings knows about the “ad hoc” mode, created so that two computers connect to each other without the help of a router.

This mode is needed so that you can easily transfer data from one computer to another. What does Wi-Fi Direct have to do with it?

And despite the fact that Wi-Fi Direct is an “ad hoc” mode, adapted specifically for mobile devices, because, as you know, transferring files via Bluetooth can take a significant amount of time, when the new technology allows you to quickly transfer a bunch of new ones from phone to phone songs or photographs.

How does this technology work?

For Wi-Fi Direct to work, you need two modern mobile devices, each of which must be equipped with a Wi-Fi module.
To quickly transfer data, each device will need to create its own access point to which another device can connect.
Moreover, the phone will create the point “on its own,” that is, the user will not have to enter addresses, invent keys, or do any other complex things.
The owner of the phone will simply have to press a few buttons and enter a PIN code, which will make the connection between the phones secure. After all the manipulations done, the devices will be able to easily exchange various data with each other.

In conclusion, we can say that wifi direct was designed specifically to make data exchange between two mobile phones faster, but can this technology completely replace Bluetooth?

That's the question! Although there are prerequisites for this, because wifi direct not only has a high data transfer speed, but also makes it possible to connect several others to one device at once, which would be almost impossible to do using Bluetooth.

Just a couple of years ago, in order to connect a TV or any other gadget to a computer, you needed to find a suitable cable and make a bunch of settings. Today things are different. It is enough to have a modern device that supports the Wi-Fi Direct function and make a few settings. Therefore, let’s consider the current topic of 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 you to transfer information between several devices that support this technology. In this case, to pair devices you only need a router, or rather an access point. No adapters or cables are needed. The devices find each other themselves.

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

However, you should immediately note several features in the operation of this function:

The data transfer speed with a direct connection can reach 200-250 Mbit/s, and the range will reach 50-100 meters.
To work with the Wi-Fi Direct function, the gadget must have a chip. This chip comes in several types: operating in the 2.4 GHz and 5 GHz bands. There are also devices, but they are not budget ones, that support operation in both bands.
When creating a connection for several devices via Wi-Fi Direct in the office, you need to understand that when connecting a third-party device, the security of data transfer is not guaranteed. Therefore, it is recommended to use this function 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, you should make a few simple settings, which we will now describe.

How to set up Wi-Fi Direct on your phone?

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

Turn on Wi-Fi in the device settings.
Once you activate Wi-Fi, the Direct function will appear in the menu. Tweak on it to open it.

We start searching for devices.

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

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

How to connect a PC to a TV via Wi-Fi Direct?

The method of connecting a computer to a TV, or vice versa, will differ from that presented above.

Using the instructions that come with your 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 desktop PC. To do this, in Explorer, select “Network” from the menu on the left. A notification appears stating that "Network discovery and file sharing are disabled." Right-click on this message and select “Enable network discovery and file sharing.”

A message will appear. You need to choose to create a private network.

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

Once DLNA is activated, you need to go to your TV's menu to view the contents of connected devices. For example, on LG TVs you need to select the “SmartShare” section. It will display the contents of folders that are allowed to be viewed in Windows 10.
Next, to start a movie on an 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 a standard Direct configuration instruction. The instructions for each TV model have a section dedicated to Direct. You can use the advice of the TV developers.

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

Wifi Direct- this is the ability for a device with WI-FI, using special programs, to act as an access point or WiFi router.

Modern TVs or tablets, as well as phones, indicate support WiFi and separate support

What is the difference between these 2 wireless connections? Wi-Fi and WiFi Direct ?

What is WIFI Direct

Wifi direct What is this — The answer to this question is as follows: if Wi-Fi Direct support is declared, the device can work as an access point, providing the ability to connect to the Internet via Wi-Fi to other devices. The most used WIFI direct solution in phones. By turning on an access point on your phone, you get the opportunity to connect via wifi to your phone with another phone, tablet, or laptop. In this case, the phone receives the Internet via the mobile network, and distributes the Internet to other devices via wifi.

Wi-Fi standard

There are no global differences, only in ordinary WiFi to connect various devices you need to use a router (separate device); when installing certain software, a router can be made from a tablet or laptop, in which case the computer will act as a router.

The principle of operation of the router consists in the fact that information is received and transmitted through one channel to one device, such as a TV, and through another channel, for example, to a tablet.

The router also routes data transmission. Devices that use only WI-FI can connect to the router using either a passwordless connection or a secure connection; if the router uses a secure connection, then you can connect to it only by knowing the password.

Wi-Fi Direct, what is it?

In this case, if the device supports Direct, it can act as a virtual access point without any additional settings or software changes (password connection is similar to Wi-Fi). To a device that supports, you can connect other devices that only support WI-FI.

Many sites include the advantage of creating a connection to a single network of various devices or directly connecting several devices.

N But in principle this statement is not entirely true. Since one of the devices, usually the most advanced device (tablet or smartphone), acts as a router.

But of course it’s convenient, no one argues, connecting, for example, a printer or TV to a smartphone by pressing one button, it’s very convenient. But nothing can replace a router for constant operation of devices on a single network. Alternatively, you can, for example, connect your tablet to watch a movie on TV or print photos from your smartphone, but this is convenient for a one-time use. But in practice, it is more convenient to buy a router for $15-20 and create a permanent computer network.
