You know what Wi-Fi technology is and use it every day. You know what Bluetooth is and use it quite often. Strengths These two technologies can be depleted and this is called Wi-Fi Direct.

You can use Wi-Fi Direct on a TV only if it is a smart TV and it even has wifi, this does not mean that you can turn it on Wi-Fi Direct– this function may simply be missing. So the Samsung ue55ju6600uxua TV has it, but the Philips 40PFS5709 does not, although both have Wifi.

You can connect to a Samsung, Sony, or HP computer or laptop with Microsoft windows 10, windows 7 or windows 8.1 installed if they support Intel WiDi, through Windows Media or Virtual Wi-Fi Direct Adapter from Microsoft.

WiFi is fast. Therefore, WiFi Direct technology was adopted to quickly transfer data between two devices, and it is even much easier to enable, configure and use and can be used for a wireless connection.

The first company to introduce WiFi Direct support was Intel: they introduced the first standard, the Centrino 2 platform, in 2008.

Then, two years later, several major players in the networking industry followed suit, such as Marvell, Atheros, Broadcom, Realtek Ralind. It is possible that your laptop's Wi-Fi is from one of these manufacturers.

Also appeared on Google WiFi support Direct for Android 4.0. Blackberry OS received an update to version 10.2, and the first to support WiFi Direct Xbox was the Xbox One, launched in 2013.

Note: Some people make the mistake of WiFi Direct wireless connections by confusing it with Ad-Hoc.

This connection connects two computers using WiFi, but its speed is limited to 11 Mbit.

How Wi-Fi Direct works

The most important principles behind the WiFi Direct standard are very simple. The operating mode is as follows: the device detects another, as if opening a wireless network. Then enter the password or press the button and you're done, the equipment is connected.

There is no need to set visibility, just enter a numeric key, just like Bluetooth technology.

Additionally, only one of the two connected devices must support Wi-Fi Direct.

To connect two devices via Wi-Fi Direct, one must create an access point, like a router, and the other device connects to that access point. This process happens automatically, there is no need to do anything manually.

You can print wirelessly and send photos from your phone to your computer, or play music on your TV from your tablet or smartphone.

In this case, you can forget about passwords. WiFi Direct technology uses Protected Setup (WPS), which is an easy way to connect two devices using secure wifi.

As with modern routers, simply enter the number displayed on the screen or press the connect button.

With simplified configuration and faster speeds, WiFi Direct is much more the best option than Bluetooth when it comes to transferring files between two or more devices.

Advantages in terms of ease of installation and scope of application, the sea is a useful standard for connection peripheral devices.

Some analysts are even predicting the end of the Bluetooth era, although the technology is new enough that it could still be years away. If you have any questions, please use the comments section below. Good luck.

Wi-Fi Direct technology - what is it? This is a cutting-edge set of software protocols that allows you to transfer files without an Internet connection. Devices that support this certificate can connect to each other and send data over a distance of up to 200 meters. The transmission speed reaches high levels - up to 250 megabits per second. It is also worth noting that this network has high channel security. Wi-Fi Direct technology is very similar to the well-known Bluetooth standard, only it surpasses it in many ways.

This data transfer method greatly simplifies the work of users

Progress does not stand still, and today you have the opportunity to perform unimaginable 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 via TV. And all this without wires, waiting time and multi-step setup.

Features of wireless technology

1. This set of protocols is developed, certified and supported by the Wi-Fi Alliance.
2. After switching on specified function on devices, they automatically detect each other.
3. To create a Direct network, you do not need a router. A router can be useful if you want to access the World Wide Web.
4. You can create a connection of gadgets “1 - 1” or “1 - many”. Paired devices include smartphones, laptops, computers, printers, keyboards, VCRs, routers, scanners, cameras, digital frames and other equipment.

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 for full-fledged network communication between devices. Also include them in shared network It is also very convenient 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 to print required 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 technology allows you to configure any modern TV brands LG or Samsung 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– enough to support Wi-Fi connections Direct was only available on LG TVs or, for example, Samsung smartphones. 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 the TV as a second monitor, connect a media player, enable display of a network resource on big screen– all this is possible with the wireless communication option under consideration. Devices that support of this protocol, allow you to create a separate working group and enjoy 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, connect it to newest model Samsung smartphone or a laptop made by LG – it’s easy and very convenient. Now any video file in HD, 3D and other formats can be studied not through the small display of a mobile device, but on the high-end large screen of a modern smart TV.

You know what Wi-Fi technology is and use it every day. You know what Bluetooth is and use it quite often. The strengths of these two technologies can be reduced and this is called Wi-Fi Direct.

You can use Wi-Fi Direct on a TV only if it is smart tv tv and it even has wifi, this does not mean that you can enable Wi-Fi Direct - this function may simply be missing. So samsung tv ue55ju6600uxua has it, but Philips 40PFS5709 does not, although both have Wifi.

Connect on a computer or samsung laptop, sony, hp with installed Microsoft Windows 10, Windows 7 or Windows 8.1 is possible if they support Intel WiDi, via Windows Media or a virtual WI-Fi Direct adapter from Microsoft.

Didn't stand aside android devices, iPhone (iPhone), for example, 5s and smartphones or tablets with Miracast support.

In general, this does not depend on the manufacturer, be it lg, samsung galaxy, philips, and Chinese meizu, zte blade, huawei honor 5a - Even a printer can support Wi-Fi direct.

What does Wi-Fi Direct mean and what is it for?

IWfi - wireless communication technology with big amount areas of application - the most common connection to the Internet.

The most common way to meet WiFi for the typical user is to access the Internet using a router.

The router is physical device, which creates an access point (AP) that you see on your smartphone, phone, or computer when searching for networks to connect to.

To connect, select a network, enter a password (if necessary), and voila - you have access to the Internet.

There are only cases when you don’t need the Internet, you want to connect only two devices and exchange data between them: send a file, for example, to a printer to print anything.

There is a technology designed to help even in these cases, and it's called Wi-Fi Direct.

Wi-Fi Direct - a little history

To send data to another device without wires and third equipment, one of the most popular types of communication is Bluetooth, which appeared in 1998.

It is ideal for connecting peripheral devices to your computer, such as a mouse and keyboard, or using wireless headphones, since they do not require fast data transfer.

WiFi is fast. Therefore, WiFi Direct technology was adopted to quickly transfer data between two devices, and it is even much easier to enable, configure and use and can be used for a wireless connection.

The first company to introduce support for WiFi Direct was Intel: they introduced the first standard, the Centrino 2 platform, in 2008.

Then, two years later, several major players in the networking industry followed suit, such as Marvell, Atheros, Broadcom, Realtek Ralind. It is possible that your laptop's Wi-Fi is from one of these manufacturers.

Google also added support for WiFi Direct on Android 4.0. Blackberry OS received an update to version 10.2, and the first to support WiFi Direct Xbox was Xbox One, launched in 2013

Note: Some people make mistakes with wireless connections WiFi Direct, confusing it with Ad-Hoc.

This connection connects two computers with using WiFi, but its speed is limited to 11 Mbit.

How Wi-Fi Direct works

The most important principles behind the WiFi Direct standard are very simple. The operating mode is as follows: the device detects another, as if opening a wireless network. Then enter the password or press the button and you're done, the equipment is connected.

With its simplified configuration and faster speeds, WiFi Direct is a much better option than Bluetooth when it comes to transferring files between two or more devices.

Benefiting from ease of installation and scope of application, SEA is a useful standard for connecting peripheral devices.

Probably every smartphone user has at least once encountered a situation where they need to quickly transfer files from one smartphone to another. If you have high-speed Internet access, you can synchronize devices, if you have a laptop and USB cable- you can upload files through it. What to do if there is neither one nor the other? The obvious answer is to use Bluetooth. But such a connection does not always provide a sufficiently high speed. What if you need to transfer many files at once?

In this case, you should pay attention to Wi-Fi technology Direct, available in many modern smartphones and providing a connection at a speed of about 50 Mb/s.
With this connection, two smartphones create a kind of local network using the same Wi-Fi transmitters, only in this case a router is not required.
The advantage is the high speed characteristic of high-speed wireless Internet access, but the disadvantage is not very good support from the software, as well as the lack of information about the procedure for creating such a connection.
Let's try to figure out how to transfer several hefty files - 25-40MB each in fifteen seconds. To do this, let's take SONY smartphones Xperia ZL and Meizu MX2 to show that the technology is universal. I will illustrate the procedure with an example SONY Xperia ZL.

Procedure:

1. Download from Play Store any program that supports Wi-Fi Direct, I chose the simplest option - File Commander. I remind you that in most Xperia smartphones This program is installed initially, so just update it to latest version, because V earlier versions Wi-Fi Direct may not be supported. The program must be installed on the smartphone from which files will be sent.

2. Go to the Settings menu - Wi-Fi.

3. Turn on the switch in the very top line, then carefully look to see if the smartphone has automatically connected to any network (status “Connected”), if connected, long press on the name of the network and in the menu uncheck “Connect automatically” (after transfer files, you can install it again). After that, turn off Wi-Fi and turn it on again with the switch in top line. We carry out the procedure on both smartphones.

As practice has shown, Wi-Fi Direct often cannot work on smartphones simultaneously with an Internet connection via Wi-Fi.

4. Click on the button with three dots in the lower right corner. Select Wi-Fi Direct. We carry out the procedure on both smartphones.

5. Click the search button in the lower left corner. We do it on both smartphones.

6. After the devices “detect” each other, click on the name of the device on any of the smartphones.

The "Connected" status should appear.

7. Go to File Commander or any similar file manager with technology support, select the files that need to be sent and long press on any of the selected files to enter the menu. Select "Send via Wi-Fi Direct".

8. Select a device from the list and click on the icon. If the list is empty, try clicking the magnifying glass icon in the top right corner.

The file transfer will now begin. Please note that, unlike Bluetooth, file transfer is carried out in a single package and without additional requests. In the status line of the receiving device, only a modest notification appears indicating the degree of completion of the operation. Received files are saved in internal memory devices in the "Download" folder.
I was unable to transfer folders this way, but I was able to transfer 10-15 files at a time, each about 30MB in size, without any problems. Transferring one such file takes only a couple of seconds.

Miracast is a technology that was developed by Microsoft for wireless transmission images, sound on the TV display 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.

Wireless Miracast technology provides accurate image transmission without the need for an HDMI cable to various devices, which support such a function. Disadvantages include unfinished functionality and rare crashes.

Method 1: Keyboard shortcut

Setup and launch Wi-Fi functions Direct using a keyboard shortcut can only take a few minutes. This process is a bit similar to connecting a computer to another device via Bluetooth.

Now you can enjoy high-quality image and sound on another device without using 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. Besides this technology supports most modern devices, making image and sound transmission much easier.
