Everything You Need To Know About WiFi 6
WiFi 6 program based on the IEEE 802.11ax standard, enables next generation Wi-Fi connectivity providing the capacity, coverage, and performance required by users—even in environments with many connected devices such as stadiums and other public venues. Wi-Fi CERTIFIED 6 networks enable lower battery consumption in devices, making it a solid choice for any environment, including smart home and Internet of Things (IoT) uses.
Wi-Fi CERTIFIED 6 provides the foundation for a host of existing and emerging uses from streaming ultra high-definition movies, to mission-critical business applications requiring high bandwidth and low latency, to staying connected and productive while traversing large, congested networks in airports and train stations.
Wi-Fi 6 is the next generation of Wi-Fi. It’ll still do the same basic thing — connect you to the internet — just with a bunch of additional technologies to make that happen more efficiently, speeding up connections in the process.
The Wi-Fi Alliance is the organization in charge of deciding, developing, and designating Wi-Fi standards. As devices become more complex and internet connections evolve, the process of delivering wireless connections also changes. That means that Wi-Fi standards — the technical specifications that manufacturers use to create Wi-Fi — need to be periodically updated so that new technology can flourish and everything can remain compatible. So far, so good.
But the awkward naming of Wi-Fi standards has become a real annoyance for the average person tried to figure out what those little letters at the end mean. The Wi-Fi Alliance is aware of this, which why they announced a new way to label Wi-Fi standards, simply by referring to the number of the generation. This will apply to the upcoming Wi-Fi 6, but will also be retroactive, applying to older standards. For example:
- 802.11n (2009) = Wi-Fi 4
- 802.11ac (2014) = Wi-Fi 5
- 802.11ax (upcoming) = Wi-Fi 6
Easier, isn’t it? This will cause a period of confusion where some products are labeled with the old code and some are just called Wi-Fi 4 or Wi-Fi 5 when it means the same thing. In time, this should be resolved as older product labeling is phased out and everyone gets used to the new, friendly names when doing research.
Features of WiFi 6
First off is lower latency. Reduced latency means there are shorter or no delay times as data is sent (very similar to ping rate and other such measurements). Everyone wants low latency connections because it improves load times and helps avoid disconnects and other issues. Wi-Fi 6 lowers latency compared to older Wi-Fi standards, using more advanced technology like OFDMA (orthogonal frequency division multiple access). Basically, it’s better at packing data into a signal.
Of course, Wi-Fi 6, will also be faster. By offering full support for technologies like MU-MIMO, connection quality will vastly improve for compatible mobile devices, which should also speed up content delivery. Even if you don’t upgrade your internet speed, such improvements can improve the speed of your Wi-Fi data anyway, so you get more information, faster.
It also means fewer dead zones, thanks to some expanded beamforming capabilities. Beamforming is the trick your router uses to focus signals on a particular device, especially if it looks like that device is having trouble with a connection. The new standard expands the range of beamforming and improves its capabilities, making dead zones in your house even less likely.
Increase Battery Life
Lastly, Wi-Fi means better battery life. There’s a term called “TWT” or target wake time, a new technology that Wi-fi 6 embraces. This helps connected device customize when and how they “wake up” to receive data signals from Wi-Fi. It makes it much easier for devices to “sleep” while waiting for the next necessary Wi-Fi transmission (this does not mean your device is turned off, just the parts used for Wi-Fi). In turn, this has the potential to save a significant amount of battery life for devices, which should make everyone happy.
