What is wi-fi direct in the phone. What is Wi-Fi direct technology - how to use it. Wi-Fi Direct will replace conventional Wi-Fi
Wi-Fi Direct how to transfer files. Do you have a Samsung Galaxy smartphone and don't know how to transfer files via wifi direct at high speed? In this article, we will see how this is done on almost all androids.
If your Samsung Galaxy smartphone supports Wi-Fi Direct function, then you can transfer large files at high speed, if you compare the transfer speed of Bluetooth and wifi direct, then the bluetooth is resting. You can transfer files via Wi-Fi Direct not only from phone to phone, but also from phone to computer or from smartphone to laptop or tablet. The main thing is that the transmitted and received devices supported the wifi direct function.
This function is very useful on those smartphones that do not have a memory card, for example, you want to transfer a movie in good quality from a computer to a smartphone, and accordingly it weighs more than one GB and it will take a lot of time to transfer such a movie via bluetooth. And if you send the same file from computer to smartphone via Wi-Fi Direct, then it will be much faster. The main thing is that both devices must support this function.
You can pre-establish a connection between the two devices from which you want to send and receive a file. To do this, go to the settings and select the Wi-Fi item. Next, activate it, and then click on the menu in the form of three dots.
Next, a menu will open where we select Wi-Fi Direct and look for available devices. Turn on Wi-Fi Direct on the receiving device to discover it. When you see on the screen the desired device to which you want to transfer the file, you need to select it. On the receiving device, confirm the connection with your android Samsung Galaxy.
Let's see how to enable Wi-Fi Direct on Samsung Galaxy Android and how to transfer files to another smartphone or other device that supports Wi-Fi Direct.
Using an example, we will see how to transfer a file from the gallery via wifi direct:
Open the gallery and select any photo, video or just a picture by touching it, after which you will see a menu at the top of the screen with possible actions for the selected file. Choose an icon that allows you to transfer the selected file in various available ways. See the attached screenshot below.
In the menu that opens, select the icon labeled Wi-Fi Direct.
After confirming the inclusion of Wi-Fi Direct on the android, it will start searching for other devices. To find another device, you need to turn on Wi-Fi Direct on that device. After you find an available device and select it, a notification will appear on the received device receiving a file via wifi direct, needs to be confirmed. Next, the transfer process from your smartphone to another smartphone or other device will begin.

Wi-Life comment: this technology is intended for personal use or use in small groups, and, it can be said, speaking on this topic, we are somewhat deviating from the main direction of the resource. Nevertheless, Wi-Fi Direct may well become a common and convenient addition to corporate Wi-Fi network infrastructures, so we decided to cover this topic on our website.
The Wi-Fi CERTIFIED Wi-Fi Direct™ mark marks devices that support a new technology that allows devices to connect directly. This makes it possible to significantly simplify tasks such as printing documents, sharing documents, synchronizing and displaying information. Devices bearing this mark can communicate with each other directly and without the need to join a traditional WiFi-standard home or office network.
Mobile phones, cameras, printers, computers, gaming devices can now connect directly to transfer content (transfer) and share applications quickly and easily. Connecting devices certified as Wi-Fi Direct is very simple and is done at the touch of a button. In this case, only one device is required to support Wi-Fi Direct. Any other wireless equipment can be used to connect to it and then exchange data. All WiFi Direct connections are secured with WPA2, which is the most advanced wireless security technology in Wi-Fi (). Wi-Fi Direct allows devices to communicate directly with each other without an access point, and there is no need to look for an Internet connection.
In what cases is it usedWi- fidirect
Devices with Wi-Fi Direct can be used for all types of applications - share content (collaboration with information), synchronize data, communicate on social networks, play games, listen to music or watch videos, etc., i.e. do all the same things you do with Wi-Fi devices today, only easier and without the need for an internet connection. Wi-Fi Direct certified devices can form connections with virtually all certified and standardized Wi-Fi devices that your friends or acquaintances already have. You only need one WiFi Direct enabled device to form a group. Now networks based on the Wi-Fi standard are not just an access medium with the main task of accessing the Internet, but it ensures that you interact with your friends everywhere.
According to recent research, users around the world said they would like to use Wi-Fi Direct to chat, share photos, display photos from portable devices on a monitor or TV screen, use video chat, and play video games together outside the home, for example , in public transport.
How WiFi Direct works
It is important to reiterate that the use WiFi Direct possible without the presence of any network WiFi. All you need is at least two devices. You may see available devices and request to connect with them, or you may receive an invitation message to join from another Wi-Fi Direct device.
In this case, the search functions for devices and services are used. Wi-Fi Direct: Wi-Fi Direct Device Discovery and Service Discovery , which allow users to set available devices and services before establishing a connection. For example, if the user wants to print a document, then he can find out which Wi-Fi networks the printer supports.
A Wi-Fi Direct certified device can establish peer-to-peer connections such as P2P, and can also participate in infrastructure-like scenarios. WiFi Direct devices can join standard networks Wi Fi like regular Wi-Fi devices. WiFi Direct devices can form point-to-point (one-to-one or peer-to-peer) or point-to-multipoint (one-to-many) topologies. The last option is similar to the BSS model.
Devices can participate in the Group as certified for WiFi Direct , and just having the usual WiFi certification. However, only the device can form and maintain a group. WiFi Direct. Regular Wi-Fi devices can only be clients in this group.
When two or more Wi-Fi Direct certified devices establish a connection, they form WiFi Direct group using technology Wi-Fi Protected Setup (simplified establishment of a secure connection in Wi-Fi ( approx. Wi- life. en) and state-of-the-art security mechanisms WiFi . For safe use Wi-Fi Protected Setup either press the corresponding buttons on both devices at the same time, or enter PIN -the code. After that, you can start doing whatever is necessary.
Р2Р technologies (Peer - to - Peer ) play an important role in cases where a fast connection is needed.
Let's take a look at some examples of using Wi-Fi Direct to provide additional user experience:
A student in a hostel needs to print out the assignment before coming to the audiotorium. Her laptop is authorized to access the university's Wi-Fi network, but she is not authorized to connect and use her printer to the Wi-Fi network. In this typical situation, a student can print documents on the printer directly using Wi-Fi Direct and at the same time check mail through the university's Wi-Fi network.
Friends have gathered for a party, film each other on the cameras of their smartphones and share photos with everyone.
-An employee of the company was on a business trip with his tablet or lightweight netbook, and then, upon arrival, in a simple way, synchronizes the files he created with his corporate laptop
In all these cases, Wi-Fi Direct will be an excellent technology that makes life easier.

A couple of years ago, in order to connect a TV or any other gadget to a computer, it was necessary to find a suitable cable and perform 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, we will consider the current topic of how to enable Wi-Fi Direct on Windows 10 and connect various devices to the system.
What is WiFi Direct?
Wi-Fi Direct is a modern wireless networking standard that allows you to transfer information between multiple devices that support this technology. At the same time, to pair devices, you only need a router, or rather an access point. No adapters or cables needed. Devices themselves find each other.
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 rate 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, it is necessary that the gadget has a chip. This chip is of several types: functioning in the 2.4 GHz and 5 GHz bands. There are also devices, but they are not from the budget, which support operation in both ranges.
- When creating a connection for multiple devices via Wi-Fi Direct in the office, you need to understand that when you connect a third-party device, the security of data transfer 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, you should perform a few simple settings, which we will now describe.
How to set up Wi-Fi Direct on your phone?
In order to apply the Direct function on the phone, you should do the following:
- Turn on Wi-Fi in the device settings.
- As soon as you activate Wi-Fi, the Direct function will appear in the menu. Tweak it to open it.
- We start searching 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, you can connect multiple devices that support the Wi-Fi Direct function. However, it is important to remember that due to different versions of Android firmware, the step-by-step procedures may differ from those presented.
How to connect PC to TV via Wi-Fi Direct?
The way how to connect a computer to a TV, or vice versa, will differ from the above.
- Using the instructions that come 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 desktop PC. To do this, in Explorer, select "Network" in the menu on the left. A notification will appear stating that "Network discovery and file sharing have been disabled." Right-click on this message and select "Turn on network discovery and file sharing."
- A message will appear. You need to 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 content of connected devices. For example, on LG TVs, you need to select the “SmartShare” section. It will display the contents of the folders allowed for viewing 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 the standard Direct setup instruction. The manual for each TV model has a section on Direct. You can use the advice of the TV developers.

Articles and Lifehacks
Previously, only Bluetooth was used for fast file transfer, but today there is technology such as Wi-Fi Direct, which is a good alternative to Bluetooth. So what is wifi direct on a phone?
What is this technology
Anyone who has at least once encountered the Wi-Fi setup at home, without using the default settings, knows about the “ad hoc” mode, designed to allow two computers to connect to each other without the help of a router.This mode is needed in order to be able to transfer data from one computer to another without any problems. 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 pack of new files from phone to phone. songs or photos.
How this technology works
- Wi-Fi Direct requires two modern mobile devices, each of which must be equipped with a Wi-Fi module.
- For fast data transfer, each device will need to create its own access point, to which the other device can connect.
- Moreover, the phone will deal with the creation of the point "independently", that is, the user will not have to enter addresses, invent keys or do any other complicated things.
- The owner of the phone will simply have to press a few buttons and enter a pin code that will make the connection between the phones secure. After all the manipulations done, the devices will be able to exchange various data with each other without any problems.
It's a question! Although there are prerequisites for this, because wifi direct not only has a high data transfer rate, but also makes it possible to connect several others to one device at once, which would be almost impossible to do with Bluetooth.
Each method of transferring files between devices has its drawbacks: Bluetooth cannot transfer large amounts of data, a USB cable is not at hand when you need it, Wi-Fi speeds can be too slow, and mobile Internet traffic is limited. But we found the best solution - using Wi-Fi without an Internet connection.
WiFi Direct function
If you need to transfer files from one smartphone to another, you can use the built-in Wi-Fi Direct function. Let's see how it works using two Android phones as an example.
Open your smartphone settings. Go to the Wi-Fi (WLAN) section. It is not necessary to connect to the Internet. Go to the Wi-Fi Direct tab - it may be hidden in the additional menu.
When transferring files between phones from different manufacturers, communication breaks and other errors may occur, so sometimes you have to use third-party software.
If you want to transfer files between phones, computers and tablets, use or special applications for transferring data via Wi-Fi. Lifehacker talked about one of these programs. available on Windows, Linux, macOS, Android and iOS. But this is not the only option.
SHAREit
To transfer files, you need to install SHAREit on both devices. The app is available for all platforms for free.
After installation, run the program. On the sending device, press the Send button and select a file or application. On the receiving device, click "Receive". A radar will appear in the center of the screen, displaying the icon assigned to another device on the network. Click on it to connect and start the file transfer.
When moving data from the phone's memory to a computer, you need to select the "Connect to PC" mode. Otherwise, there are no changes. A search screen will appear asking you to select the icon of the receiving device.
Filedrop works in a similar way. The application must be installed on all devices that will participate in the file exchange.
Run the program to establish a connection. Usually pairing is set up automatically, but sometimes you have to enter a four-digit code. On the phone, you can see it by clicking on the button in the upper right corner. On - by right-clicking on the program window.
If you are transferring data from your phone, click on the box icon. A simple manager will open in which you can select a file to send. When moving data from a computer, you can simply drag it into the program window.
File transfer is also available through the Filedrop website. When opened in a browser, the main page displays devices running the application connected to the same Wi-Fi network.
But here you can encounter failures: some devices are not detected or do not accept files. When working with applications, such problems were not found.
Instashare
The Instashare program once solved the problem with transferring files on Apple devices. However, after the mass distribution of the AirDrop function, the existence of Instashare only within the Apple environment no longer made sense. Therefore, the developers have made the application cross-platform.
Instashare works just like SHAREit and Filedrop. The only difference is that you have to pay for the program on a PC. Apps for iOS and Android can be downloaded for free.
To move data between iPhone and Android smartphones, there is - they all also use the Wi-Fi Direct function.
