What is WiFi Direct, what is it for on the phone? You have probably transferred files via Bluetooth more than once and sometimes you had to wait a very long time for one large file to be transferred. WiFi Direct is a great opportunity to transfer large files at high speed from one phone to another phone, tablet or other device that supports Wi-Fi Direct technology.
How to transfer files via WiFi Direct? Since in our time technologies are improving every day, we can watch high-quality movies on our phone, and the phone is also capable of shooting no less high-quality video, which can take up more than one GB of memory. Now imagine if we want to transmit or receive a good quality video, then even the fastest bluetooth will take a lot of time. That's why, to transfer large files, we'd better use wifi direct with which we can transfer files from one phone to another phone or device that supports this function ten times faster. Now I think you are starting to understand what wifi direct is on a phone and what it is for.
How to transfer files over wifi? Nothing complicated on the transmitting phone, you need to enable wifi, and on the receiving phone or other device, enable wifi and wifi direct. Next, select the desired file, picture, music or video on the phone and select wifi direct in the transfer functions, and confirm reception on the receiving device. after which you will see for yourself how fast you can transfer via wi-fi compared to Bluetooth or infrared. You have probably already understood basically what Wi-Fi Direct is and why it is needed, this function helps to transfer files at high speed to another device.
Here's how you can enable wifi direct on android, perhaps on some devices the way to turn it on may be slightly different, but I think if you think a little yourself, it will not be difficult to find. And so, to find where wifi direct is enabled on Android, open "Settings" then "All settings" then "More" and check the box next to "WiFi Direct" and that's it, the Wi-Fi direct function is enabled. Now you can transfer and receive files at high speed, but before that, do not forget to turn on Wi-Fi on the transmitting device.

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 the ability to display images from smartphones "over the air", without the need for wires - watch photos, videos, listen to music on a large scoreboard, use your smartphone as a remote control and much more. But in order to take full advantage of these functions, it is important to make the right settings.
How to connect your phone to a Sony Bravia TV via Wifi is described in the instruction manual. But, despite the detailed manual, many users encounter various difficulties during the installation process. For example, how to act if the smartphone is controlled not by Android, but by iOS, or what to do if the phone does not have Direct, where can I find the access code from WiF-i in TV, or why did everything follow the instructions, but nothing happens? These questions will also be discussed in this article.
About technologies
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. For their docking, 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 bandwidth is identical to the bandwidth of 802.11 devices. In other words, the data exchange rate 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 under consideration 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 very well. Any owner of a smartphone, tablet, laptop and any other Miracast-enabled mobile gadget can play games on a tablet or smartphone and display an image on a large screen, display photos, multimedia content. The TV will display everything that happens on the display of the gadget. And all this "over the air", without wires and with just a few touches.
How to set up wifi on 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 in the following way:
- 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 must 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 get into 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 Wi-Fi.Direct 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 pressed, a window with the name of the network and a secret code will appear on the TV screen. This data is subsequently entered manually in the Wi-Fi debugs of the connected mobile device. If the connection was established successfully, a notification will appear on the monitor of the TV receiver.
Now you know how to connect Wi-Fi to a Sony Bravia TV. Immediately after carrying out the actions 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.

There are many terms that are incomprehensible to ordinary users, which is why it is worth understanding each of them. You may be interested in the question of what is WiFi Direct. This technology was announced a long time ago, it was intended to simplify the establishment of a connection between a pair of separate Wi-Fi devices. In a sense, this is Bluetooth based on Wi-Fi. It differs from the first in greater speed and distances, and from the second in ease of setup and safety. And everything seems to be fine, but it's really worth figuring it out.
A bit of history
To understand what WiFi Direct is, you need to look into the past. To organize wireless communication of consumer devices, Bluetooth was directly used, which is quite simple, has a short range, low cost and quite reasonable energy requirements. In our time, when smartphones have almost caught up with computers in terms of performance, we want something more. And here it is worth noting that there is Wi-Fi, which works faster, it has a greater range, but there is an important nuance.
The original idea was that Wi-Fi can work in two modes: direct, when several devices organize a simple one, and infrastructure, involving the use of an access point, which is a kind of traffic arbiter. The second option developed and moved forward over time, and the first one just got stuck in the nineties: now it is not supported by all household devices, it is characterized by low speed, as well as insecurity. That is, it is dangerous, inconvenient and completely inapplicable, so modern Wi-Fi simply cannot do without an access point.
And how are things now?
Manufacturers of consumer Wi-Fi are so eager to simplify the life of modern users that at the moment there are almost no settings for home access points, and many of them work directly out of the box on defaults. Many users simply do not know how to enable WiFi. It is this factor that has allowed the emergence of a huge number of free Wi-Fi from the best Internet providers. This was the reason for such a strong popularization of Wi-Fi, but at the same time it gave rise to many myths about the insecurity of such connections. All of the above has led vendors to change their priorities in favor of a simple and secure wireless network. This is where the question arises of what WiFi Direct is.
Peculiarities
This connection method has many advantages:
Secure direct connection between devices, established similarly to Bluetooth, that is, you just need to select the appropriate item from the list, without thinking about PSK and SSID;
The speed of such networks is much faster than traditional Bluetooth;
Considerably greater distance between devices is allowed;
A high degree of reliability and security is guaranteed by the always-on WPA2, which cannot be disabled.
Implementation
So, what is WiFi Direct, it becomes clear, it remains to deal with issues related to the intricacies of providing such access. The adoption of a new amendment to the 802.11 standard will take several years. It was decided to contrive within the specifications and standards available at the moment.
WiFi is fast. Therefore, WiFi Direct technology has been adopted to quickly transfer data between two devices, and it is even much easier to turn it on, configure and use it and can be used for 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.
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 Xbox WiFi Direct was the Xbox One, which launched in 2013.
Note: Some people confuse WiFi Direct with Ad-Hoc wireless connections.
This connection connects two computers using WiFi, but its speed is limited to 11 Mbps.
How WiFi Direct works
The most important principles that underlie the WiFi Direct standard are very simple. The mode of operation 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 with Bluetooth technology.
In addition, 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 this access point. This process happens automatically, there is no need to do anything manually.
You can print to a wireless printer and send photos from your phone to your computer, or play music on your TV from your tablet or smartphone.
With this, 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 a 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.
Advantages in terms of ease of installation and scope of application, the sea is a useful standard for connecting peripherals.
Some analysts are even predicting the end of the Bluetooth era, although the technology is new enough that it could be years from now. If you have any questions please use the comments section below. Good luck.
The TV can be directly connected to a Wi-Fi Direct/Wi-Fi compatible device (such as a smartphone, computer) that also supports the “DLNA Push Controller” function. Device contents such as photos/music/videos can be played on the TV. This feature does not require a wireless router (or access point).

When the standby screen for Wi-Fi Direct mode is displayed, press the OPTIONS button, then select [Show device list / Erase].
To unregister a device, select the device you want to delete from the list, then click the button. Then select [Yes] on the confirmation screen.
To unregister all devices, press the OPTIONS button in the list, select [Delete All], then [Yes] on the confirmation screen.
Displaying a Dialog Box When You Try to Connect a Device to a TV
Activating this function avoids connecting an unnecessary device.
When the standby screen for Wi-Fi Direct mode is displayed, press the OPTIONS button, then select [Registration Notice].
Please note that after declining a registration request from a device, that device will not be able to connect until it is removed from the device list.
To connect a rejected device, press the OPTIONS button, select [Display device list / Erase], then delete the rejected device. Then make a new connection to this device.
Skipping connection steps from the second time
After registering the device by performing the following setting, you can immediately start playing content on the TV screen by sending the content from the device (excluding Wi-Fi Direct mode).
Press the HOME button, and then select [Settings] → [Network] → [Standby for Wi-Fi Direct] → [On].
If the TV is connected to (or an access point) at 5 GHz using a USB wireless LAN adapter, set [Standby for Wi-Fi Direct] to [Off].
- Wi-Fi is a mark of the Wi-Fi Alliance.
- Wi-Fi Direct is a mark of the Wi-Fi Alliance.
Notes
- If the TV is connected with a 5 GHz wireless router (access point) using a USB wireless LAN adapter:
- - 5GHz connection will be disabled in Wi-Fi Direct mode and you will not be able to use functions such as Media Remote, TrackID™, etc.
- - The connection will be resumed when you exit Wi-Fi Direct mode.
- When connecting devices, the following must be taken into account:
- - Devices that support Wi-Fi Direct: 2.4 GHz connection (5 GHz is not supported).
- - Devices that do not support Wi-Fi Direct: IEEE802.11n/g, 2.4GHz connection (5GHz is not supported).
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.
wifi direct- this is an opportunity for a device with WI-FI, using special programs, to act as an access point, a WiFi router.
In modern TVs or tablets, as well as phones, support is indicated WiFi and separate support
What is the difference between these 2 wireless connections WiFi 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 the access point on the phone, you get the opportunity to connect via wifi to the phone with another phone, tablet, laptop. In this case, the phone receives the Internet via a mobile network, and distributes the Internet to other devices via wifi.
WiFi standard
There are no global differences, only in ordinary WiFi to connect various devices, you must use a router (separate device), when installing certain software, you can also make a router from a tablet or laptop in this case, the computer will act as a router.
The principle of operation of the router consists in the fact that one channel receives and transmits information to one device, such as a TV, and another channel, for example, to a tablet.
The router also performs data transfer routing. Devices using 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 only connect to it by knowing the password.
WiFi 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 ability to create a connection to a single network of various devices or the direct connection of several devices as an advantage.
H Basically, this statement is not entirely true. Since one of the devices, as a rule, this is the most advanced device (tablet or smartphone) acts as a router.
But of course, it’s convenient, no one argues, for example, connecting a printer or TV to a smartphone with the press of a button, it’s very convenient. But nothing can replace a router for the constant operation of devices in a single network. Alternatively, you can, for example, connect a tablet to watch a movie on a TV or print photos from a smartphone, but this is convenient one-time. But in practice it is more convenient to buy a router for $15-20 and create a permanent computer network.
