What is WiFi 6?

In 2019, the newest WiFi standard was introduced: WiFi 6 (also known as 802.11ax). What 5G is to mobile internet, WiFi 6 is to fixed internet. With this new variant, you achieve higher speeds for multiple devices simultaneously, there are fewer delays, you have better security and WiFi coverage. We would like to explain to you what WiFi 6 entails, the advantages it has over WiFi 5 and which applications are made possible by WiFi 6. Furthermore we offer you an overview of all WiFi 6 devices from the Capestone portfolio.

Technical aspects of WiFi 6

The difference between WiFi 5 and WiFi 6 is huge, on many levels. WiFi 6 has a number of technical improvements over WiFi 5. The biggest difference is the ability to efficiently control multiple devices. This is made possible by the following two technologies: MU-MIMO and OFDMA.

MU-MIMO stands for “multi-user, multiple input, multiple output. You can compare this to a fleet of delivery vans. With Wifi 6, you don’t have one delivery van driving back and forth to deliver packets of data, but eight. The other technology, OFDMA, ensures that the bus does not have to go back to the distribution center (the router) all the time, but if it still has space after the first delivery, it can go directly to a second address. And that’s why it can operate much faster than WiFi 5. WiFi 6 uses MU-MIMO by default to serve multiple users in a network simultaneously. WiFi 6 routers apply this technique to both uploading and downloading, which makes the connection of these routers a lot faster.

What are the differences between WiFi 5 and WiFi 6

  • Speed: WiFi 6 can reach a speed of up to 9.6 Gbps compared to 3.5 Gbps of its predecessor WiFi 5. However, this does not mean that the speed is actually higher. The speed is mainly determined by the connection to the Internet. The new WiFi variant mainly makes strides in the smart control of various devices in the network. This means that if you connect several devices at once, you will not lose speed.
  • Battery: In addition to speed, WiFi 6 also reduces the power consumption of devices. Devices can go into what is called a coordinated sleep mode, which can save a lot of power. This ensures that your devices last longer on the same charge. Setting fixed times for devices to be connected to the Internet is applicable to Internet of Things devices, for example. Here you can think of smart thermostats or smoke detectors. In addition to a longer battery, the connection to devices that do need to be connected 24/7 is also optimized, because the network is less unnecessarily burdened.
  • Security: WiFi 6 also offers better security. The new technology: WPA3 makes it harder for hackers to crack passwords because the security key is constantly changing.
  • WiFi coverage: The technology of WiFi 6, also provides better wireless coverage. With the new WiFi variant comes better WiFi coverage. WiFi 6 operates on a high and low frequency. The low frequency gets through thick walls and ceilings better, this will also improve reception on another floor.
