Improves the wireless video transmission speed of routers.

More and more people are using wireless networks to watch movies and video chats. The limitations of wireless networks are shown. The transmission speed in wireless networks is greatly affected, especially video files, this article focuses more on speed and introduces how to improve the speed of wireless video transmission.

I. In addition to the basic 802.11n functions used for video optimization, we should also consider using other built-in Priority Methods in network components to improve video performance, in addition to the basic 802.11n function used for video optimization, continuous measurement of Wireless Video performance to ensure video quality is also critical, we should also consider using other built-in Priority Methods in network components to improve video performance. After this, continuous measurement of Wireless Video performance to ensure video quality is also critical.

2. Extend the priority to the wired network. You need to find the Access Point (AP) mapped between the Wi-Fi multimedia class, 802.1 p (MAC layer) and differential service code point (or DSCP) IP priority mark ).

In addition, access points with video sensing capabilities and access points with the correct priority for specific video streams should be considered. Because Wi-Fi multicast often reduces the data transmission rate and increases the error rate, you should look for functions that can optimize multicast videos. For example, a video sensing access point can automatically select a high rate for multicast, or convert a cable multicast packet to a wireless unicast frame.

III. This type of conversion is very effective, especially when only a few clients receive videos. Some products can consider this and continue to use multicast when necessary. Other products are actually more sensitive to specific codecs and frame types. This kind of intelligence can be used to adjust Access Point behavior, reduce the loss of more important frame types, perform transcoding (convert to more fault-tolerant encoding) or video conversion, and manage the diverse features of the client.

Generally, client diversity reduces WLAN performance, especially for wireless videos (especially for multicast videos ). However, many vendors have developed optimization technologies to handle diversity, including transmission beam forming and radio management adjustments.

4. Through transmission beam, the Access Point will customize transmission for each client to reduce errors. The radio management algorithm can change the call time allocated to each device, so that updated or faster clients will not be dragged down by older or slower clients.

Ideally, these optimization technologies should also be video-aware. Wireless Mesh networks can optimize some wireless video applications (such as outdoor wireless cameras and digital signage ), although many dual-RF 802.11n Access Points support wireless mesh networks, you must be aware that not all access points give priority to video optimization through wireless return links.

5. In 802.11n WLAN, the signal strength does not indicate the performance of wireless videos. The uplink and downlink data transmission speeds vary depending on the multi-path behavior, access point, client, and chipset.

Therefore, the only way to ensure the audience watching experience is to use representative applications and devices to measure the performance of videos and multimedia applications in place. For interactive videos, DF is maintained at a low level (for example, (less than 50 milliseconds) is very important, but this has little impact on IPTV, streaming media, or video on demand. The media loss rate measures the number of dropped packets per second, it is very important for high-quality videos.

As for how to improve the wireless network video transmission method, I believe you have learned how it works. If you need it, you can improve the video transmission speed by yourself, the premise is that you need a good wireless router.
