What is WiFi 6?

WiFi 6 (802.11ax) is the latest standard in WiFi technology, which is an improvement on the previous generation WiFi 5 (802.11ac) standard. It is mainly built to improve the user’s surfing experience by increasing network speed. It improves transmission efficiency and reducing network congestion in environments with a large number of devices.

Like the previously released WIFI technical standards, WiFi 6 is also compatible with previous standards. And any terminal device that can connect to WiFi can access the WiFi6 network.WiFi 6

Advantages of WiFi 6

1. Transmission Rate

The maximum transmission rate of WiFi5 is 3.5 Gbps, while the maximum rate of WiFi6 can reach 9.6 Gbps. WiFi 5 only involves the 5 Ghz frequency band, while WiFi 6 covers both 2.4 Ghz and 5 Ghz frequency bands.WiFi 6 comparision

2. Security

If a WiFi 6 device needs to be certified by the WiFi Alliance, it must use the WPA 3 security protocol, which is more secure. When we are using a public network, it improves the security of data transmission by personalizing data encryption. If the password is entered incorrectly multiple times, it will be considered an attack. So it will block WiFi authentication to prevent the emergence of brute force attacks. In a variety of ways, active protection and passive defense are combined to protect our use of public networks. The security of the WPA3 security protocol is further improved, which can better prevent brute force cracking and brute force cracking.WPA3 WiFi 6 Security

3. Target Wake Time (TWT)

WiFi 6 introduces Target Wake Time (TWT) technology, which allows active planning of communication time between the device and the wireless router, reducing the use of wireless network antennas and signal search time, which can reduce power consumption to a certain extent and improve device battery life.Target Wake Time (TWT)

4. OFDMA(Orthogonal Frequency-Division Multiple Access)

In the OFDM technology before OFDMA, the device uses a fixed bandwidth of 20, 40, and 80 MHz when transmitting data. When multiple users want to transmit data, no matter how large the data transmitted by each user, they must occupy a separate channel. Other users have to wait for the previous user to queue up to transmit data after the end of the transmission.

And OFDMA can divide the channel according to the size of each data according to the needs of the client. One client only occupies part of the channel resources, so that the data transmiting by multiple clients can get the same user experience on the truck at a faster speed at the same time. The space is fully utilized, the waiting time is also reduced, the efficiency is improved, and the delay is reduced.OFDMA and MU-MIMO

5. MU-MIMO Technology

MU-MIMO technology is already available in the WiFi 5 technical standard, but only supports downloading, not uploading. In the WiFi 6 technical standard, it can fully support both download and upload.

MU-MIMO technology allows multiple devices to communicate with the router simultaneously without waiting in line. However, unlike OFDMA, which allows communication with multiple users by subdividing the channel. MU-MIMO communicates with multiple users by using different spatial streams.

6. 1024-QAM Modulation

WiFi 6 uses 1024-QAM modulation technology. Compared with the 256-QAM modulation technology of WiFi 5, WiFi 6 encodes more data in the same amount of spectrum. Increasing the data throughput of a single spatial stream by 25%, enabling faster transmission speeds when using high bandwidth applications.1024 QAM WiFi 6

7. BSS Coloring

To put it simply, BSS Coloring is to color label each device independently, and then add the corresponding label to the data. So that even if there are different devices in the same channel, there will be a corresponding address when transmitting data and it will sent directly to the location without wrongly sent to another device.BSS Coloring

Why we need WiFi 6?

If you have a lot of smart devices in your home and a lot of people online; you usually use some high bandwidth applications such as live broadcast software and video software; or you have gigabit broadband at home, but has been using routers for several years, there will also be some delays and freezes when surfing the Internet and feel that you have not experienced the Internet speed that you should have. Then WiFi 6 router must be the best for you. And now more and more mobile phones and computers support WiFi6, if you want to change the router, you must change to WiFi 6, and it will bring you faster speed.

Baudcom offers various types of WiFi 6 related products. For more information, please feel free to contact us.

Testimonials

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
