What is Wi Fi Direct on TV

You can connect your smartphone to your TV in various ways, using cables or over the air. One popular and simple wireless option is the Wi-Fi Direct option. In this article you will learn what it is, how it works, and how to use Wi-Fi Direct on TV. This feature is supported by most modern home electronics companies.

What is Wi-Fi Direct

Wi - Fi Direct is one of the means for wireless data transfer. With its help, a TV without a router can serve as a signal relay point. By connecting a mobile phone or laptop to it, you can display the image directly on the screen. Two or more devices are connected into one network without additional connecting devices.

A Wi-Fi module is available in all modern devices. Wi-Fi Direct technology is almost identical to it. Using this means of communication allows you to transmit information at a frequency of 2.4 GHz over a distance of about 200 meters. More expensive modules operate in the 5 GHz band.

A little history

The standard we are considering was developed by WECA several years ago. This company is actively involved in all kinds of technologies related to Wi-Fi.

After developing a full-fledged standard that allows the Internet to be transmitted over the air, creating technology for transferring data between devices was a logical step.

To do this, it was necessary to come up with something that would allow the use of Wi-Fi without routers and routers.

Therefore, they came up with a chip that is placed inside a smartphone, tablet or other device. It is, in fact, a mini-router.

In general, WECA is an alliance of the largest Wi-Fi equipment manufacturers.

Initially it included the following organizations:

3Com;
Cisco, which was then called Aironet;
Intersil (aka Harris Semiconductor);
Agere (aka Lucent);
Nokia;
Symbol Technologies.

Most of them still belong to the alliance. They support all developments, including the development of Direct.

Pros and cons of technology

Like all communication methods, Wi-Fi Direct on a TV has its advantages and disadvantages. Compared to other solutions, it has undeniable advantages.

Easy connection. There is no need to purchase a router. A network will be created between two devices, you connect to it and use it.
High data transfer speed. Most modern devices are equipped by manufacturers with the appropriate protocol.
Wi-Fi Direct is supported by most modern devices. Therefore, there will be no connection problems with your TV, tablet or smartphone.
Universality of technology. It is supported by all operating systems from Windows 10 to Android and iOS.

On a note!
If, for example, an LG or Samsung TV does not have this function, you can purchase a universal adapter for any TV model. It will work as a built-in module. Let us also list the disadvantages of the technology.

Low level of security. A user with any mobile device can connect to your connection.
Small connection area. Wi-Fi Direct works within one room. TVs and mobile devices do not have such powerful antennas for transmitting and receiving signals as routers.
Battery drains quickly. Due to the high data transfer speed on a smartphone, energy is wasted quickly.

Solution

If connection problems persist, then you need to take a number of simple but effective actions. Most often, these methods help correct the situation and restore the operation of the TV with Wi-Fi.

Reboot

You need to reboot the TV and router. In some cases, the software begins to work incorrectly, which is easily corrected by turning on the devices again. The main thing when rebooting the TV is to disconnect it from the local network. For some models, you will need to not just turn it off, but cut it off from the power supply for 10-15 seconds.

When rebooting the router, you need to wait about 15 seconds before turning on the device again. This is necessary to completely close the previous session. Only in this case the settings will be reset. Otherwise, the turned on router will work within the previous session.

Manual data entry

If automatic configuration does not produce results, then the data will need to be entered manually. To do this, you need to open the Wi-Fi settings, find the “IP address” line and enter an IP from the local range. You can find the appropriate values in the router administration panel.

The value 255.255.255.0 is usually entered in the “Subnet Mask” field. The parameter is responsible for redirecting clients on the local network. The IP router address that is used to open the router settings must fit into the “Gateway” line.

Important! You can also find out the “Subnet Mask” and “Gateway” parameters through any other computer connected to the router. You need to launch the command line, where you need to enter “ipconfig /all” and confirm the action.

DNS errors

DNS errors must be corrected to connect directly to the Internet, avoiding the manufacturer's servers. You can find out the DNS server from your provider by contacting their support service. There are also open servers from large companies (Google and Yandex). To use Google address servers, you must specify 8.8.8.8 as the primary IP server, and 8.8.8.4 as the secondary one.

Important! In some cases, you cannot specify an additional address; then only the main IP server is entered.

Changing the connection method

If you connected to Wi-Fi by manually entering a password, you should try using WPS. WiFi Protected Setup is a technology that allows you to quickly connect your TV to the Internet. You need to activate it not only on the TV, but also on the router. To do this, you need to inspect the device body for the presence of a corresponding button or open the control panel.

Smart TV does not work on TV: solution to all problems

It is difficult for television to compete with the Internet in terms of variety of video content, this is a known fact. But the situation is balanced by the Smart TV service - it actually allows you to use the TV for Internet surfing. The process of connecting it is simple, you only need an Internet connection and a minimum of effort to set up. But sometimes a problem arises - Smart TV does not work, which can be caused by several factors.

Features of using the function on iPhone

Let's consider connecting the Wi-Fi Direct function on the iPhone.

First, you need to make sure that the latest version of the operating system is installed on your smartphone. If there was an update, you need to install it and then restart your mobile device.
Also on the TV you need to check the OS update, as well as the Wi-Fi Direct connection.
First, the feature is enabled on the device you want to connect to. Once in the “Menu”, go to the “Settings” section. Find "Wi-Fi Connection" and activate it.
Then Wi-Fi on the phone turns on. Among the available networks, you should find the one that the TV creates (the TV name will be displayed).
You can connect to the device by entering the Wi-Fi password indicated on the TV screen.
If the connection does not occur, it means that a mistake was made somewhere. Check all the points carefully, especially that the password is entered correctly and whether there is an update. You can turn off and restart your iPhone.

Way to connect to TV via USB

A reliable, but rather archaic way to synchronize a smartphone with a TV is to connect via USB.

The connection procedure is as follows:

Using a USB cable, connect your smartphone to the TV;
Go to the settings of your phone, and select “Connect as USB drive” there;
In the TV menu, go to “USB devices”, and in the menu that opens, select your smartphone model.

Ordered signal streams

There are two main sets

rules for local circulation of large volumes of data. These are DLNA and Miracast. However, the latter is the most appropriate in this case. For each of them, leading manufacturers have developed a lot of programs.

DLNA supports

multimedia traffic: video, photo, music. To operate in wireless mode, a central switch with an access point is required. The server is a transmitting device on which a special program creates a server. The client simply displays the image on the screen. So software installed on a computer with DLNA uses a central switch to use the large TV screen.

Miracast

can operate in point-to-point mode and, in addition to providing transport for typical audio and video files, can stream desktop images. The developers have provided functionality that ensures smooth playback of the video stream and the absence of desynchronization. Establishing contact and beginning the exchange of signals occurs in a couple of touches. The video signal is transmitted using the H.264 codec in Full HD. The sound is processed in AC3 format in 5.1 format. A separate advantage is that the standard is supported by all smartphones equipped with an operating system starting with Android 4.2.
