Every year there are more and more new technologies that are designed to improve and make our life easier. One of them is WiFi Direct. What it is will become clear if we take a closer look at the technology itself and the principle of its operation. Devices that support this method of communication are capable of transmitting data at high speeds - up to 250 megabits per second, and over a fairly long distance - up to 200 meters. And the reliability of the network is ensured by a higher degree of channel protection. To build a network on such a basis in a router, there is simply no need.
Key Features
It's worth taking a closer look at WiFi Direct. What's this? This is a new information transfer standard that allows several gadgets to communicate with each other without using a router or other network device. It is not necessary for a person to participate in this process, since the devices are capable of automatically detecting each other. So far, this is not even a standard, but a certification. Currently, two devices can connect wirelessly only with the involvement of a router as an intermediate link. However, a router is no longer required when using WiFi Direct. What it is, and how such a method works, is discussed here.
This method allows you to connect several gadgets at the same time. In addition to devices such as standard laptops, smartphones and telephones, digital photo frames, scanners, printers, VCRs, etc. can be connected to the network, and here the main condition is the presence of an appropriate chip.
As it was before?
Home networks have already experienced the introduction of similar services and protocols several times. Among the existing ones, WiFi Direct is considered the most promising development, which has only one obstacle to development - the reaction of consumers.
Some have the opinion that this standard will soon completely replace the well-known Bluetooth, which is quite popular at the moment. So, if we consider WiFi Direct, what it is will become clear after determining the advantages of such a solution in comparison with traditional Bluetooth. Here we can talk about a higher data transfer rate, an increased distance, as well as a reliable channel security. However, there are also disadvantages that are quite significant.
Characteristics
WiFi Direct chips are worth considering. How to use this technology will become clear later. Cells can be of one of two types: for the 2.4 gigahertz range, 5 gigahertz and simultaneously support both of these values.
The technology has a couple of useful features: Device Discovery and Service Discovery. With their help, gadgets not only find each other and integrate into a network without any human participation, but also allow you to learn about the capabilities of each device. For example, if you need to transfer an audio file from a smartphone somewhere, then in the list of receiving devices there will be only those that are able to accept and use this type of data, and all the others will simply be excluded from it. This allows the user not to scroll through the entire list in search of a suitable gadget, but only to select the one that is displayed.
Difference from other types
A conventional WiFi network assumes the primacy of the access point, which controls all other devices. The WiDi network also has a coordinator, but this function is transferred from one device to another, depending on the power, autonomy, and functionality. So, the list of preferences looks like this: laptops, tablets, smartphones, consoles, followed by peripherals such as printers, audio systems, digital cameras and others.
Flaws
So, now you understand what WiFi Direct is; how to use it is also no longer a question. It is worth dealing with its shortcomings. They are the ones who question the development of technology and its popularity.
Main disadvantages
- Cluttering the air. When the wireless network is organized in the usual way, all devices are connected to one access point. In this sense, we can talk about the big difference between WiFi Direct. How to set up such a network? Pretty simple. Here we can talk about the simultaneous creation and operation of several networks in which gadgets communicate with each other, transferring data. This leads to the fact that, for example, several tens or hundreds of networks will operate in a multi-storey building, creating a real mess on the air, since they all broadcast with different powers and frequencies. Such networks cannot be controlled, which is why they create a real clutter of the ether.
- Poor network security. Despite the fact that manufacturers of WiFi Direct Android devices talk about the better security of such networks in comparison with Bluetooth, in reality everything is different. While such a gadget is used exclusively in the home network, we can talk about its safety, but if you come with it to the company's office, where it will begin to find other devices and connect to them, a problem already arises. WiFi Direct network for Windows can be used as a proxy through which data will be obtained from any device on the network, and even corporate information. It will be difficult for any specialist to control all the networks created by such a device, which will gradually lead to the prohibition of this standard in enterprises. As a result, it may remain popular only for home use, or disappear altogether.
- High energy intensity. On the one hand, it can be used to transfer large amounts of data over long distances and at high speeds. However, modern gadgets drain so quickly that such an additional load may well become a burden.
- Increased range of this technology is not always an advantage. Your network can be hacked from a long distance, it can be wedged into and used against you.
- The use of WiFi Direct requires the use of a special chip as simple WiFi is not suitable for this purpose. At the moment, there are gadgets that are equipped with both chips, but there are not very many of them.
conclusions
The main disadvantage of implementing such a technology is that its support is provided by a separate chip that differs from traditional WiFi. And since at the moment not so many manufacturers include such modules in their devices, users will not want to purchase new gadgets to use this technology.
Wifi has become a novelty and turned everyone's head, but science does not stop at this discovery. Everyone is used to connecting to the Internet without any interfering wires for the computer and not waiting for ages while the mobile Internet downloads something to your phone. Now all of this technology is using Wi-Fi.
A small router that can distribute the Internet to several devices at the same time - these are the technologies of reality. This type of Internet access has already become a habit of the entire planet and it is difficult to imagine your life without using it. When we come to visit someone, our first question will be what is the name of the Wi-Fi access point and the password from it.
Wi-Fi Direct - a few words about technology
Now the Wi-Fi Direct wireless connection (also called Wi-fi Peer-to-Peer) is gaining popularity. Now it will be described in detail what kind of connection it is and how it should be included.
What is this new product for?
It is necessary to exclude the router from the data transmission chain. This means that you can connect one device to another without using a router. If you have no idea what Wi-Fi Direct is, then you need to remember how file transfer via Bluetooth took place. This novelty can be used on almost every new device. It is also possible to enable Wifi Direct on Windows 10. If you have a laptop, then this function will become very convenient.
Wifi direct windows 10 - how to enable
If the adapter supports this technology, then you can enable wifi direct on windows 10 by entering the properties of the network connection.
- Suppose your printer has such a function, then on a computer that supports it, we look for a network and select a printer as a network. You need to connect to it by entering a password. After that, you can safely start printing information. This is the main goal of the technology, which will help you connect directly without unnecessary headaches.
- You can also connect a TV and enjoy watching movies on the big screen without using the router. For such a connection, only a couple of factors are required: the presence of this function on both devices and on your PC, by sharing its folders.
- You can connect not only two devices, but also create entire groups of devices. So, for example, a laptop owner can be connected to a group and use this unique technology to distribute the Internet. There is nothing difficult in connecting, you only need to press one button.
Many computer users say with confidence that soon wifi will not be as popular as wifi direct. Its main advantage is considered to be connected in places with a problematic connection.
Wi-Fi Direct how to transfer files... You have a Samsung Galaxy smartphone and don't know how to transfer files via wifi direct at high speed? In this article, we'll take a look at 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 transmission 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 it accordingly weighs more than one GB and it will take a lot of time to transfer such a movie via bluetooth. And if you transfer 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 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, we activate it, after which we 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. On the receiving device, enable Wi-Fi direct to detect it. When you see the desired device on the screen, to which you need to transfer the file, you need to select it. On the received device, confirm the connection with your Android Samsung Galaxy.
Let's see how to enable Wi-Fi Direct on Samsung Galaxy and how to transfer files to another smartphone or other device that supports Wi-Fi Direct.
For 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. Select the 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 with the signature Wi-Fi Direct.
After confirming that Wi-Fi Direct is turned on, the android will start searching for other devices. To find another device, you need to enable Wi-Fi Direct on that device as well. After you find an available device and select it, a notification will appear on the receiving device. receiving a file via wifi direct, you need to confirm. Then the transfer process from your smartphone to another smartphone or other device will begin.

Manufacturers of mobile devices on the Android platform are increasingly equipping their products with a Wi-Fi Direct chip, but not all owners of modern tablets and smartphones know what it is.
Why do you need this chip and what advantages does it provide you? To understand this, let's first look at what Wi-Fi Direct means.
The programming platform is one of the most important components for smart TV. You can easily find new apps and organize the ones you have installed. Bulgaria has kids, fitness and local development. For example, in the Cook Me app form, you have a complete cookbook with over 200 great classified recipes by country, food and dish, and the morning newspaper reading can also be streamed to TV with a dedicated 24 hours and trust.
It reproduces a much wider color range, up to 4 times the normal color tones. Available in Film Mode, Natural Mode, Game Mode, and Advanced Sports Mode. We never unplug the TV, but in fact, most TVs still draw power even when they are turned off.
Wi-Fi Direct is a new type of data transfer. It opens up the ability to exchange information between multiple devices.
This technology is similar to Bluetooth, that is, there is a direct connection without routers and access points. But, unlike Bluetooth, Wi-Fi Direct has a faster connection speed and a longer range.
Preparing for first use
Before performing these procedures, complete the following steps.
Registering a device
You know this technology and you still use it every day. You know that too, and you still use it quite often. What if you combine all the strengths of the two? In this tutorial, we'll talk a little about this technology and how it works. You use it a lot, of course.It is a wireless communication technology with many uses, the most common of which is Internet connectivity. A router is a physical device that creates an access point or hotspot that you see from your smartphone, phone, or computer when you search for a network to connect.
Thanks to this technology, you can interconnect not only smartphones and tablets, but also other devices equipped with a corresponding chip. For example, the Wi-FiDirect chip is built into most modern TVs, and you can directly connect such a TV to a smartphone, laptop, computer, and so on. Thus, you can create a home network without the involvement of a router.
Connecting to another device
Choose the network you want, enter your passphrase and get it: you have access to the Internet. But there are also cases when you do not need the Internet, you only want to connect two devices and exchange data between them: send a file or print something on a printer. There is a technology to help you in these cases, and it is called.
The need to send unmanaged data to another device without the need for a third device is nothing new. The way it works is also quite simple: the device detects another, as if it were detecting a wireless network. Then enter the password or press the button and the equipment is connected.
Wi-Fi Direct chip is a separate wireless module; due to the fact that this technology is new, such a chip is not yet used in laptops.
Even the most modern and expensive laptops cannot boast of the presence of this equipment, and among smartphones and tablets, not all gadgets support this technology.
When the function is not available
As you already understood from the above, the answer to the question of how to set up Wi-Fi Direct on a laptop is that it cannot be done. A chip is a hardware component: either it is there or it is not. Accordingly, this type of data transfer is not available to laptops.
This procedure is performed automatically, you do not need to do it manually. The services available depend on the types of devices connected: you can print to a wireless printer, send images to a digital photo frame, send files from your phone to your computer, or play music on your TV on your Portable or Smartphone player. Oh, and about passwords: you can forget them. As with modern routers: just enter the screen number or press a button and the connection will be made.
The phone will now automatically detect nearby phones and connect if you want to. On the other phone, you will receive a confirmation message, you accept this connection. Or where you just hang out with friends. In shops, bars and cafes, in a restaurant, you can quickly and easily check your emails, or you can search for everything you need online.
In the absence of a chip, since you will not be able to turn on Wi-Fi Direct on a laptop, you can use alternative data transfer options. To do this, you need an access point to which the devices participating in the exchange of information will be connected.
If you do not have an access point at hand, then you can distribute the network from a laptop to Android by establishing a direct connection.
You will also need to install a program that will share the required data. For example, you can use the following programs to exchange files between your computer and smartphone:
- FTP server.
- Airdroid.
- MyPhoneExplorer.
The first application only needs to be installed on a smartphone. The program will generate an IP address that you need to register on your computer in a browser or file explorer. The rest of the applications need to be installed on the phone and computer, and only then connect the devices. It is a great alternative to Wi-Fi Direct, allowing you to freely share files at high speeds.
How to connect and transfer files
So, you already know what Direct Wi-Fi is. Now let's move on directly to using this function. If your smartphones or tablets are equipped with the required chip, then we turn to the question of how to use the Wi-FiDirect technology.
In fact, everything is very simple. Enter the Wi-Fi settings on your device.
Turn on the wireless adapter.
Now press the "Wi-Fi Direct" button.
The same procedure should be done on the second device. Thus, we have included the required function. The search starts automatically. Now all that remains is to select the equipment to be connected from the list of available connections.
As you can see, everything is very easy and simple. It should be noted that this technology has two convenient functions:
- Device Discovery.
- Service Discovery.
Simply put, gadgets can not only be combined into one network without the participation of intermediaries (routers, access points, and so on), but also determine the capabilities of each device in the network. For example, if you need to send a video, then only those devices that can receive and play it will be displayed in the list of available connections.
Considering all of the above, we can conclude that support for Wi-Fi Direct is the presence in the device (laptop, smartphone, etc.) of the appropriate chip that allows you to create networks without a router and exchange data directly.
What is Wi-Fi Direct: Video
Connecting modern devices, be it a laptop, smartphone or smart TV, is technically not a problem today. Another thing is that if every TV or modern laptop has an HDMI connector, then in smartphones, ultrabooks and similar equipment, the constructive placement of this port is not always justified. This means that it is not always possible to effectively use a wired connection familiar to the user. Yes, and the wired connection, although it works great, still causes some inconvenience due to the length of the cable, the inability to send a file to a new device without having to physically plug the cable into the port.
The exchange of information between devices in this version is possible only through a cord. And when there are a lot of them, this is not only inconvenient, but also leads to a breakdown of the port over time due to constant cable reconnections in order to transfer the file. Therefore, a universal wireless technology Wi-Fi Direct was developed, which allows you to establish a full-fledged network connection between devices. It is also very convenient to include them in the general network due to the provision of the maximum data exchange rate.
The ability to include any equipment in the home network
Wi-Fi Direct allows you to wirelessly connect between any devices that support this technology. Smartphones manufactured by Samsung can be easily connected to a modern smart TV of LG brand in order to configure it to display information stored in a mobile device.
But, the ability to use the TV as an additional display is not the only function of this technology. Wi-Fi Direct is the ability to connect gadgets such as cameras, printers to the receiving device to print the desired file without using wires. Gaming and any certified mobile devices that have an antenna for a Wi-Fi connection have the same capabilities. Today this sign can be found on household appliances made by Samsung, Sony, LG and other well-known companies.
Wireless antenna - the norm for modern technology
This wireless technology offers to configure any modern TV brand LG or Samsung to receive and display information on the screen without using a cord. At the same time, in order to connect the devices to the network via a wireless connection, you need to make a couple of clicks, and then it works without interruptions.
Wi-Fi Direct creates a separate channel between devices that is separate from the standard office wireless network. In addition, in order to connect the devices to this network, it is enough that the Wi-Fi Direct connection is supported only on an LG TV or, for example, a Samsung smartphone. The rest of the equipment is connected to them using standard modules, where there is a wireless antenna that works on standard protocols.
The ability to watch a video file format in HD quality on anything
You can take advantage of Wi-Fi Direct wireless connectivity to work with any type of application. Transferring any necessary file, synchronizing data, using the TV as a second monitor, connecting a media player, turning on the display of a network resource on a large screen - all this allows the considered option of wireless communication. Devices that support this protocol allow you to create a separate working group and take advantage of the benefits that come from this.
Antenna for wireless communication today is implemented in hardware in almost every modern media device. And after Samsung and LG have launched more than one smart TV on the market, which has an antenna for wireless communication, connecting it to the latest Samsung smartphone or LG laptop is easy and very convenient. Now any video file in HD, 3D and others format can be studied not through a small display of a mobile device, but on a high-quality large screen of a modern smart TV.
The capabilities of our smartphones are growing, and with them. Already today we can store files of a rather large size on a smartphone, but it is quite problematic to share them. or cellular data doesn't provide enough speed. This is why many manufacturers have been equipping their smartphones with Wi-Fi Direct for several years now. Colleagues from PhoneArena explained how to use it to transfer large files between smartphones or between smartphones and computers.
Some Android devices do not require additional applications to work with Wi-Fi Direct, but even on them it will be easier to use the function with the application.
Install the application from this link, launch it and immediately proceed with the selection of the files you want to transfer. You can select files by type as well as select entire folders for transfer. Once you find the file you want and decide to transfer it, the app prompts you to make sure both devices are on the same Wi-Fi network.
The next screen of the app will guide you to pair the two devices. If the SuperBeam application is installed on the second Android smartphone, then it is enough to simply scan the QR code. You can also navigate in your browser to the IP address specified in the application and access the selected files. This can be done both on another smartphone and on a computer. Download files of any size with maximum speed.
