Directional antennas are a vital component in wireless communication systems, renowned for their ability to transmit and receive signals with a high degree of directionality. These antennas are designed to focus their radiation pattern in a specific direction, enhancing the signal strength in that direction while minimizing interference and noise in other directions. Directional antennas come in various shapes, sizes, and configurations, each tailored to meet specific communication requirements. In this article, we will delve into the classification and key features of directional antennas.

In fact, the reasons for the smart TV and the TV box Karton are similar, but there are only slight differences, so Xiao Bian still separate to write ~
Why smart TV stuck?
Excessive background applications affect TV memory
When it comes to background applications, some users may not understand it enough. In fact, simply speaking, the background application is an application that was opened before, but it is still a part of the program that runs in the background of the system because you did not quit the application and it causes you to use other applications. With the increase of background applications, the memory of the system itself will become smaller and smaller. After such a vicious circle, it will easily cause the system to fail or fail.
Too much system waste
Due to the lack of good equipment maintenance habits, the system's own garbage files, residual installation packages, cache files, and unloaded software residual files, etc., are accumulated, which affects the operation of the system and the corresponding speed.
Poor system optimization
Poor system optimization is mainly reflected in the excessive software that is not needed on the TV. Take Xiaomi TV as an example. In the native system of Xiaomi TV's airframe, there are many applications that we do not need on TV. These applications will not be used during normal TV use, but they are due to remote systems. Software, most of them are set to boot from the start, which will take up a lot of system memory, and thus the speed and effectiveness of television.
Device hardware is damaged
This is easy to understand because the equipment is damaged due to aging of the line, human external force and other factors. When this happens, Xiao Bian does not recommend that you carry out self-inspection. For security reasons, it is necessary to contact after-sales service.
Why is the TV box stuck?
The better the sales volume of the box, the more obvious is the Karton phenomenon. This is actually the problem of the source channel. The channel is crowded and the signal transmission is hindered. The TV broadcast will be carded.
TV manufacturers are not good at optimizing the system....Because native Android systems have many system applications that we do not need on the TV (for example: camera, calendar, gallery, music, video, stocks, phone, address book, SMS...etc.) These are all we will not use, but they are always running in the background, and these softwares are usually booted automatically. If they are not optimized, they will occupy the system's running memory. This will cause us to get stuck while running other applications.
There are many Android machine software that will be resident in the background, all of which make the memory of the machine that is already small in memory be further squeezed out, the memory balance becomes smaller, and the memory needs to be used when running other programs or when operating, creating conflicts. stuck!
Long-term use leads to excessive system garbage (for example, the system's own garbage files, remnant installation package files, some cache files generated by other software, invalid garbage, uninstall software residual files, etc.)
Understand the reasons for Caton, then our users should also go to the right medicine is the ~ Here are a few solutions:
To increase the speed of the Internet, many times it is the Caton that is caused by too slow a network speed. If the bandwidth in your home is lower than 4M, please upgrade to 4M or above, so that there will be a network speed environment that is not easy to get stuck.
If you look at live Kartun's words, please replace the live broadcast software. Since each manufacturer comes with its own R&D live broadcast software, replacing the live broadcast software during peak hours may solve the problem of watching TV cards.
Second, please use the small amount of memory of live broadcast software, otherwise the TV's small memory full, I do not believe that when watching TV will not card; 3 If you can stagger the prime time watching TV, this time watching the live special people, The background server is under so much pressure that Caton becomes a matter of everyday life.
If there are more useless native system applications, you can also try to obtain ROOT permissions and clean up system applications. However, it should be noted that not all applications can be deleted. Improper removal or moving operations may cause the system to crash, so it should be used with caution.
The last one, we must develop the habit of regularly cleaning machine memory
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
