Technology Wi-Fi Direct Allows devices to exchange data directly, without intermediaries like routers or access points. This is especially convenient when you need to quickly transfer photos, videos, or even mirror your smartphone's screen to a large TV screen. But how do you properly set up this connection if the interfaces Samsung, LG, Sony And Xiaomi Are they different? And why does the connection sometimes drop after a few minutes?
In this article, we will cover not only the basic setup steps Wi-Fi Direct on TVs and smartphones (Android And iOS), but also nuances that manufacturers are silent about. For example, why on some models Samsung Smart TV From 2018 to 2020, the feature only works with devices running Android 9 and below. Or how to bypass the restriction Apple for use Wi-Fi Direct V iPhone (spoiler: there are workarounds).
You will also learn how to check the compatibility of devices, what file formats are supported for transfer, and what to do if the TV “does not see” the phone, despite it being turned on. Wi-Fi DirectAt the end of the article is a FAQ with answers to the most frequently asked questions, including the difference between Wi-Fi Direct, Miracast And DLNA.
What is Wi-Fi Direct and how is it different from other technologies?
Wi-Fi Direct — is a wireless communication standard that allows devices to create a direct network peer-to-peer (point-to-point) without the participation of a router. Unlike the classic Wi-Fi, where all devices connect to one access point, here one of the devices acts as a "host" (for example, a TV), and the other - a "client" (smartphone).
Key differences from other technologies:
- 🔄 Miracast: transmits only the screen (mirroring), whereas Wi-Fi Direct Allows you to share files and manage devices.
- 📡 DLNA: requires a router in the network, whereas Wi-Fi Direct works without it.
- 🔌 Bluetooth: limited by speed (up to 2-3 Mbps) and range (up to 10 m), whereas Wi-Fi Direct provides up to 250 Mbps at a distance of up to 200 m (in theory).
It is important to understand that Wi-Fi Direct does not replace Wi-Fi completely. For example, for streaming videos in 4K It's better to use a router with support Wi-Fi 6, as a direct connection may be less stable. However, for transferring photos or controlling a TV from a smartphone Wi-Fi Direct — the perfect solution.
⚠️ Note: On some TVs LG (series UK6300 and below) function Wi-Fi Direct It can automatically turn off after 10 minutes of inactivity. This saves power, but it interferes with long file transfers.
