What is Wi-Fi 6 and why has it been the best for a long time?



A few weeks ago we learned the details of the new Wi-Fi standard Wi-Fi 6, that is, to get large amounts like upload and data downloads, much needed in both Wi-Fi networks.

du Wi-Fi Alliance In 2019, it was mentioned that WiFi 6 will be available, which is expected to start with the first computers and phones in the second quarter of the year. But why is Wi-Fi 6 so important?

If the speed is higher, but that does not matter

Yes, WiFi 6 (802.11ax) It allows you to obtain higher speeds for loading and unloading than Wi-Fi 5 (802.11ac), but there is not much difference, and it is not necessary.

And according to the WiFi Alliance and TP-Link data, a stream ranges from 433 Mbps to 5 Wi-Fi to 600 Mbps on Wi-Fi 6 and The maximum theoretical speed is 9.6 Gbps on Wi-Fi 6 and Wi-Fi 5 is 6.9 Gbps.There is a positive difference, but it's not surprising.

If the speed is not the most important, then what is it? Well, the answer is simple, the two best things that have Wi-Fi 6 are security and low latency, that is to say, less connection with a lot of devices connected to the same network.

WPA3 embraces Wi-Fi 6

It is something that we can not guarantee the safety of Wi-Fi networks, WPA2 was quite safe, but it's not slip-and this was proved many times, even though it was the worst time it took a while to upgrade and upgrade to WPA3.

Do not let WiFi free of charge

Because the WPA3 protocol is safer it provides better encryption, so even if the passwords were "simple", it would be safer, on the other hand, Setting up for other devices is much easierFor example, it can connect computers through QR codes to make the processes much faster.

Less network connections

Over time, we realize that we need to connect more devices to our Wi-Fi network, something that reduces the speed of downloading and downloading many connected devices at the same time, but Wi-Fi 6 significantly improves this situation and Thanks to OFDMA technology (Multiple input Orthogonal Frequency-Division).

In summary, while OFDMA connects your device to a Wi-Fi network, the bandwidth channel is distributed to achieve a lower latency and better efficiency for Wi-Fi 5, when our router sends information to the device, the entire channel bandwidth was used.

Of course, it is currently very theoretical and we must demonstrate the efficiency of new technologies, but for now it is intended to solve the most common Wi-Fi networks, especially public networks.

Of course, these are not just WiFi 6 enhancements, nor do they speak as well Better energy efficiency connected devices, a Better improvement in the flow of device data and achieve better performance.

We now expect routers and devices to be available with this technology, although this new standard also supports past standards, so there is no problem connecting our older devices to new routers.
