This article introduces what ac and ax mean in the router. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Operating environment: windows7 system, Dell G3 computer.

The AC1200, AC1900, AC2100 that we see starting with AC is WiFi5, while AX1800, AX3000, and AX3600 are the hot WiFi6 that have just been promoted in the last year or two. You see the WiFi5 router at the beginning of AC and the WiFi6 router at the beginning of AX.

Maybe you don't know much about the classification criteria of WIFI, so here's a simple science popularization:

802.11g (released in 2003), also known as Wi-Fi 3, theoretical maximum transmission rate up to 54Mbps

802.11n (released in 2009), also known as Wi-Fi 4, theoretical maximum transmission rate of 600 Mbps

802.11ac (released in 2014), also known as Wi-Fi 5, has a theoretical maximum transmission rate of 6.9G bps

802.11ax (released in 2019), also known as Wi-Fi 6, has a theoretical maximum transmission rate of 9.6G bps

The question is, should we buy a WiFi5 router or a WiFi6 router?

It depends on your budget. If your budget is only 200 yuan, then buy an AC2100 and use a few mobile phones at home.

If your broadband is 300m or 500m, with a budget of about 500m, you can buy a WiFi6 router at this time. AX3600 is a good choice, and almost all the new phones in 2020 will support WiFi6.

The difference of WiFi6

At the same time, WiFi6 uses OFDMA technology which is homologous to 5G, combined with 1024-QAM high-order modulation, which can support the maximum 160MHz bandwidth and the speed is nearly 3 times faster than WiFi5.

Intelligent frequency division technology can support more devices and increase the capacity of access devices by 4 times. The multi-concurrency of access devices can reduce the queuing phenomenon, actively avoid interference coloring, and reduce the delay by 2 to 3. Support on-demand wake-up function when the terminal device is on standby, reducing terminal power consumption by 30%

For example, we compare the scenario in which the router transmits to the device as a fleet. Under the WiFi5 standard, the convoy can only be dispatched to one customer at the same time, even if there is an empty car, it will start as usual. If a car breaks down (disturbed), the whole fleet will not be able to start. Under the WiFi 6 standard, a fleet departing at the same time can form a team of at least 26 adjacent cars, each team can be dispatched to different customers, and if a car breaks down (disturbed), only the team will be affected.

Usually when we are at home, we often find the neighbor's WiFi signals, which will interfere with our own WiFi transmission. WiFi 6 uses interference coloring technology to mark neighbor network signal frames passing through the wall, so that the user's router can ignore them. WiFi signals between neighbors can transmit data simultaneously on the same channel without interfering with each other, reducing the interference rate by 30%.

There is also a big difference in power consumption between WiFi 6 and WiFi 5. Using WiFi 6 technology, the wireless router negotiates the WiFi wake-up time with the terminal to wake up on demand, while the rest of the sleep time does not consume power. While WiFi 5 can only communicate with one device at the same time, all terminals connected to the same route are either in the transmission state or in the waiting state, and are out of order, and the waiting state still needs power consumption.

So much for sharing the meaning of ac and ax in the router. I hope the above content can be helpful to everyone and learn more knowledge. If you think the article is good, you can share it for more people to see.
