Smartphone screen and media sharing
Function Screen Mirroring Screen mirroring is one of the most popular Wi-Fi module features. It allows you to display images from your smartphone, tablet, or laptop on a large TV screen in real time. Miracast, AirPlay And DLNA operate over a wireless network, providing transmission of video streams, photos, and even sound with minimal latency.
To use this feature, both devices must be on the same local network, which guarantees secure data transfer and a stable connection. You can present a presentation to colleagues, share vacation photos, or play mobile games on the big screen. This turns your TV into a universal display for all your gadgets.
It's important to note that high-resolution video transmission requires support for the 5 GHz Wi-Fi standard, as the 2.4 GHz frequency may not be able to handle the data stream without loss of quality. Some manufacturers implement their own protocols to improve connection stability, but basic standards work on most devices.
Why does the picture lag during broadcasting?
Lag is often caused by congestion on the 2.4 GHz channel from neighboring routers or physical obstacles (such as walls) between the TV and the router. Switching to 5 GHz usually solves the problem.
Control your TV from your smartphone
Wi-Fi allows you to use your smartphone as a fully-fledged remote control, which is especially convenient when the standard remote is lost or out of battery. Specialized apps from manufacturers, such as LG ThinQ, Samsung SmartThings or universal solutions like Google Home, allow you to control the volume, change channels and enter text from the phone keyboard.
Entering text queries to search for videos or Wi-Fi passwords on your smartphone screen is significantly faster and more convenient than navigating with the cursor on your TV's on-screen keyboard. This eliminates the need for multiple button presses and speeds up the setup process. Additionally, some apps allow you to use your phone's microphone for voice search if your TV doesn't have a built-in microphone.

Comparison of wired and wireless connections
When setting up a home theater, you often have to choose between connecting via cable Ethernet (LAN) and wireless connections. Each method has its own advantages and disadvantages, which affect stability and maximum data transfer speed. Understanding these differences will help you choose the best option for your situation.
Wired connections are traditionally considered more stable and interference-free, but they require cable installation, which isn't always aesthetically pleasing or physically feasible. Wireless technology sacrifices some stability for convenience and the freedom from unnecessary wires in the home.
| Parameter | Wi-Fi (Wireless) | Ethernet (Cable) | Bluetooth (Adapters) |
|---|---|---|---|
| Maximum speed | Up to 1000+ Mbps (Wi-Fi 6) | Up to 1000 Mbps (Gigabit) | Up to 3 Mbps |
| Signal stability | Depends on interference | High | Average |
| Mobility | High | Absent | High |
| Difficulty of installation | Minimum | Requires gasket | Minimum |
It is worth noting that modern routers of the standard Wi-Fi 6 They're practically on par with wired connections in terms of speed and stability in a typical apartment. However, for mission-critical tasks like low-latency online gaming or viewing 8K content, cable may still be preferable.
⚠️ Please note: Distance from the router and the presence of concrete walls can reduce Wi-Fi speed by up to 50%, so for TVs located far from the signal source, it is better to consider a cable or repeater.
Software Updates and Security
Modern Smart TV run on complex operating systems such as Android TV, Tizen, webOS, which require regular updates. Manufacturers release patches that fix security vulnerabilities, add support for new codecs, and improve app performance. Without an internet connection, your TV won't receive these important updates automatically.
A lack of updates can cause some apps to stop running due to changes in service-side security protocols. Furthermore, outdated software may contain vulnerabilities that could potentially allow attackers to access your home network.
Automatic updates typically occur in the background while your TV is in standby mode. This ensures that the next time you turn it on, you'll be using the latest version of the system, complete with bug fixes and new features.
