Still insist on 11n? 11ac dual-band router swept

Old wireless router at home has not lost it? Still "enjoying" Caton and a slow wireless Internet experience? It is believed that many users still use wireless router products whose wireless standard is IEEE 802.11n, and now the most mainstream product has become a dual-band gigabit wireless router whose wireless standard is IEEE 802.11ac. Especially mobile devices such as smart phones, tablets, and laptops, their wireless network cards have also been upgraded to support 11ac high-speed wireless networks. Compared with 11n wireless routers, what are the advantages of 11ac wireless routers?

11ac wireless router more and more popular

In actual life, there are still a large number of users with 11n wireless routers. Some friends will feel that the 11n technology is not outdated. It is so common in daily life that it really does not need to replace the router. Moreover, after replacing the 11ac wireless router by yourself, what are the obvious changes in the use of mobile phones, tablets, etc.? More friends said that 11ac is fast, but the speed of the external network can not reach so fast, home is still a small water pipe, and 5GHz signal through the wall, the price is expensive, or old and practical 11n wireless router now, at the very least The price is not bad!

Less interference in 5GHz band, high speed does not stop

I only heard about using 11ac to go online, but what exactly is a fast method? The high speed of 11ac benefits from the MIMO technology that emerged in the 11n era. In the state of 1×1 MIMO, the rate is 433 Mbps. Using 3×3 or more MIMO can easily break through Gigabit. In an ideal state, wired transmissions have been exceeded. Particularly worth mentioning is that 11ac wireless networks also support MU-MIMO, which is multi-user MIMO. When multiple devices are connected at the same time, they will not interfere with each other. This will greatly improve throughput performance when multiple users access the wireless router at the same time, especially if there are many devices in the home that need to access WiFi at the same time, and the Internet will not be more smooth.

Multiple devices access without pressure

In addition, for home users, the export bandwidth is only one aspect of network speed, and the intranet transmission speed is equally important. For example, users can wirelessly access high-definition movies stored in smart routers using smart phones, laptops, etc. These high-definition movies are very bulky, they are very slow to transmit in a normal 11n network environment, and they must be viewed using a wireless network. It is also very smooth and often stuck. The high-speed network provided by 11ac has doubled the transmission rate, enabled high-speed transmission, and made it possible to watch high-definition movies and even Blu-ray videos.
