Wifi direct why is it needed. Wi-Fi Direct what is it? Access point. Who is the boss in the group?

Miracast is a technology that was developed by Microsoft for wirelessly transmitting images and sound to the display of a TV and other gadgets. This feature is available for all devices that have an appropriate Wi-Fi adapter. This article will describe the process of enabling Miracast in Windows 10, as well as solving some problems associated with its operation.

Miracast wireless technology provides accurate image transmission without the need for an HDMI cable to various devices that support this function. Disadvantages include unfinished functionality and rare crashes.

Method 1: Keyboard shortcut

Setting up and running Wi-Fi Direct using a keyboard shortcut can take just a few minutes. This process is a bit similar to connecting a computer to another device via Bluetooth.

Now you can enjoy high-quality picture and sound on another device without the need for cables.

Method 2: System “Options”

You can also connect everything via "Options" systems. This method differs from the first only in its implementation, but you get a similar result.

That's how easy it is to add a device via "Options" and use the capabilities of Miracast.

Solving some problems

Enabling Miracast in Windows 10 is quite easy, so you shouldn't have any difficulties. In addition, this technology is supported by most modern devices, which makes image and sound transmission much easier.

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 benefits does it provide you? To understand this, let's first look at what the phrase Wi-Fi Direct means.

The software platform is one of the most important components for smart television. You can easily find new applications and organize the ones you have installed. Bulgaria has children, fitness and local developments. For example, in the form of the Cook Me app, you have a complete cookbook with more than 200 excellent classified recipes by country, food and dish, and reading the morning newspaper can also be transferred to the TV with special 24 hours and trust.

It reproduces a much wider color range, up to 4 times greater than conventional color shades. Available in Movie Mode, Natural Mode, Game Mode and Advanced Sports Mode. We never unplug the TV, but the reality is that most TVs still use electricity even when they're 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 or access points. But, unlike Bluetooth, Wi-Fi Direct has faster connection speeds and a longer range.

Preparing for first use

Before you perform these procedures, complete the following steps:

Device registration

It is a wireless communication technology with many uses, the most common being Internet connectivity. A router is a physical device that creates a hotspot, or hotspot, that you see from your smartphone, phone, or computer when you are looking for a network to connect to.

Thanks to this technology, you can connect not only smartphones and tablets, but also other devices equipped with the appropriate 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. This way you can create a home network without a router.

Connecting to another device

Select the network you want, enter your passphrase and get it: you have Internet access. But there are also cases when you don't 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 that will help you in these cases, and it's 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 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; Because this technology is new, such a chip is not yet used in laptops.

Even the most modern and expensive laptops cannot boast of having this equipment, and even among smartphones and tablets, not all gadgets support such technology.

In what cases is the function not available?

As you already understood from what was written above, the answer to the question of how to set up Wi-Fi Direct on a laptop will be that it is impossible to do. A chip is a hardware component: either it is there or it is not. Accordingly, this type of data transfer is not available for laptops.

This procedure is performed automatically, you do not need to do it manually. The available services depend on what types of devices are connected: you can print to a wireless printer, send pictures to a digital photo frame, send files from your phone to your computer, or play music on your TV on a portable player or smartphone. Oh, and about passwords: you might forget them. As with modern routers: simply enter the screen number or press a button and the connection is made.

Now the phone will automatically detect nearby phones and connect if you want to do so. On the other phone you will receive a confirmation message, you accept this connection. Or where you just meet with friends. In shops, bars and cafes, in restaurants you can quickly and easily check your emails, or you can search for everything you need online.

If you don’t have a chip, since you won’t be able to enable Wi-Fi Direct on your laptop, you can use alternative data transfer options. To do this, you will need an access point to which the devices involved in the exchange of information will be connected.

If you don’t 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 necessary data. For example, to exchange files between a computer and a smartphone, you can use the following programs:

• FTP server.
• Airdroid.
• MyPhoneExplorer.

The first application needs to be installed only on your smartphone. The program will generate an IP address, which must be registered on your computer in a browser or file explorer. The remaining applications need to be installed on the phone and computer, and only after that the devices must be connected. This is a great alternative to Wi-Fi Direct, allowing you to freely share files at high speed.

How to connect and transfer files

So, you already know what Direct Wi-Fi is. Now let's move on to using this function. If your smartphones or tablets are equipped with the required chip, then we move on to the question of how to use Wi-FiDirect technology.

It's actually very simple. Go to your device's Wi-Fi settings.

Turn on the wireless adapter.

Now click on the "Wi-Fi Direct" button.

The same procedure should be done on the second device. Thus, we enabled the function we required. In this case, the search starts automatically. Now all that remains is to select the equipment you want to connect from the list of available connections.

As you can see, everything is very easy and simple. It is worth noting that this technology has two convenient functions:

• Device Discovery.
• Service Discovery.

Simply put, gadgets can not only be united into one network without the participation of intermediaries (routers, access points, etc.), but also determine the capabilities of each device on the network. For example, if you need to transfer a video, the list of available connections will only show those devices that can receive and play it.

Considering all of the above, we can conclude that Wi-Fi Direct support means the presence in the device (laptop, smartphone, etc.) of an 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 structural placement of this port is not always justified. This means that it is not always possible to effectively use the wired connection that is 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 cord into the port.

In this version, information exchange between devices is possible only through a cord. And when there are a lot of them, this is not only inconvenient, but also leads over time to damage to the port due to constant reconnections of the cable in order to transfer the file. Therefore, a universal wireless communication technology, Wi-Fi Direct, was developed, which allows you to establish a full network connection between devices. It is also very convenient to include them in a common network due to the provision of maximum data exchange speed.

Ability to connect any equipment to your home network

Wi-Fi Direct allows you to wirelessly connect any devices that support this technology. Samsung smartphones can be easily connected to a modern LG smart TV to configure it to display information stored in the mobile device.

But the ability to use a 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 in order to print the desired file without using wires. The same capabilities are available for gaming devices and any certified mobile devices that have an antenna for Wi-Fi connection. Today this sign can be found on household appliances produced by Samsung, Sony, LG and other well-known companies.

Wireless antenna is the norm for modern technology

This wireless communication technology allows you to configure any modern LG or Samsung TV to receive and display information on the screen without using a cord. At the same time, to connect devices to the network via a wireless connection, you need to make a couple of clicks, and after that it works without failures.

Wi-Fi Direct creates a separate channel between devices that operates separately from the standard office wireless network. In addition, in order to connect devices to this network, it is enough that 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, which have a wireless antenna that operates on standard protocols.

The ability to watch a video file in HD quality on anything

You can take advantage of Wi-Fi Direct wireless connectivity to work with any type of application. Transfer any necessary file, synchronize data, use a TV as a second monitor, connect a media player, enable display of a network resource on a large screen - all this is possible with the wireless communication option under consideration. Devices that support this protocol allow you to create a separate one and take advantage of the benefits that flow from it.

A wireless communication antenna is now implemented in hardware in almost every modern media device. And after Samsung and LG launched more than one smart TV on the market that has an antenna for wireless communication, connecting it to the latest model of a Samsung smartphone or a laptop made by LG is easy and very convenient. Now any video file in HD, 3D and other formats can be studied not through a small display

Each method of transferring files between devices has its drawbacks: it is impossible to transfer large amounts of data via Bluetooth, a USB cable is not at hand when you need it, Wi-Fi speed may be too slow, and mobile Internet traffic is limited. But we found the optimal solution - using Wi-Fi without an Internet connection.

Wi-Fi 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's 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, connection interruptions 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 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 application is available for free on all platforms.

After installation, launch the program. On the sending device, click the Send button and select the 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 establish a connection and start transferring the file.

When moving data from the phone memory to a computer, you need to select the “Connect to PC” mode. Otherwise there are no changes. A search screen will appear where you need 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 file sharing.

To establish a connection, launch the program. Usually pairing is set up automatically, but sometimes you have to enter a four-digit code. On your 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're transferring data from your phone, tap the box icon. A simple manager will open in which you can select a file to send. When moving data from your computer, you can simply drag it into the program window.

File transfer is also available through the Filedrop website. When you open it in a browser, the main page displays devices running the application connected to the same Wi-Fi network.

But here you may encounter failures: some devices are not detected or do not accept files. No such problems were found when working with applications.

Instashare

The Instashare program once solved the problem with transferring files on Apple devices. However, after the massive adoption of AirDrop, it no longer made sense for Instashare to exist solely within the Apple environment. Therefore, the developers made the application cross-platform.

Instashare works the same way as SHAREit and Filedrop. The only difference: you have to pay for the program on your PC. Apps for iOS and Android can be downloaded for free.

To move data between iPhone and Android smartphones, they all also use Wi-Fi Direct.

Wi-Fi is new and has turned everyone's heads, but science doesn't stop with this discovery. Everyone is used to connecting to the Internet without any interfering computer wires and not having to wait forever for the mobile Internet to download something to your phone. Now all this technology uses 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 throughout the planet and it is difficult to imagine your life without using it. When we come to stay with someone, our first question is what the Wi-Fi access point is called and its password.

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 very actively. Now we will describe in detail what type of connection this is and how it should be turned on.

Why was this new product created?

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 occurred via Bluetooth. This new product can be used on almost every new device. It is also possible to enable Wifi Direct on Windows 10. If you have a laptop, this feature will be 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 network connection properties.

1. Let’s say your printer has such a function, then on a computer that supports it, look for a network and select the printer as the network. You must connect to it by entering a password. After this, you can safely start printing the information. This is the main goal of the technology, which will help you connect directly, without unnecessary headaches.
2. You can also connect a TV and enjoy watching movies on the big screen without using a router. For such a connection, only a couple of factors are required: the presence of this function on both devices and on your PC, providing shared access to its folders.
3. You can connect not only two devices, but also create entire groups of devices. So, for example, the owner of a laptop can be connected to a group and, using this unique technology, distribute the Internet. There is nothing complicated about connecting; you just need to press one button.

Many computer users confidently say that wifi will soon become less popular than wifi direct. Its main advantage is considered to be connection in places with problematic communications.
