In an article in the summer of 2017, we explain which are the differences between frequencies of 2.4 GHz and 5GHz supported by routed Wi-Fi and the connected devices. At the same time, we explain what the standards mean 802.11b, 802.11g, 802.11n, and802.11acAnd at what download speed you can reach with them. You can find the article here.
In April 2018, Wi-Fi Alliance (the non-profit organization that develops and certifies the Wi-Fi technology) announces the introduction of a new standard. 802.11ax. To be simpler, the standard name was given up, and the new technology has received the name of Wi-Fi 6, while previous technologies have been renamed. 802.11.ac It's now Wi-Fi 5, again 802.11n has become Wi-Fi 4.
What is Wi-Fi 6 and what speeds can be touched with this technology
Wi-Fi 6 is the latest Wi-Fi standard technology. This does not mean that something has changed in the frequency spectrum. Wi-Fi compatible routers 6 It also operates in standard 2.4 GHz and 5 GHz lanes respectively. But it changes Transmission technique andThe simultaneous handling technique of data, Wi-Fi 5 (802.11ac) uses a technique calledQuadrature Amplitude Modulation (QAM), and the ability is of 512-QAM. Wi-fi 6 reaches to 1024-QAM, which allows the transmission of 10 bits at the same time. This translates to an improved speed with up to 25% compared to Wi-Fi 5.
The great innovation of Wi-Fi 6 is however Orthogonal Frequency-Division Multiple Access (Ofdma). OFDMA allows the decomposition of a wireless channel into smaller pieces, so that Each customer to benefit from a dedicated bandwidth. As a novelty is the modification of the width of the channel for the 5 GHz band. It has been doubled from 80 MHz la 160 MHz, which offers greater support for data. The 2.4 GHz band channel remained unchanged, at 40 MHz.
According to Intel, this will lead to an improvement with approximately 40% speed for each user, especially in crowded areas.
Mobile Phones / Smartphone with Wi-Fi support 6
Being a new technology, it has not yet been implemented on a large scale by mobile devices.
Apple added support for Wi-Fi 6 on iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max, but no model of iPad or MacBook does not support this standard. The owners of Samsung Galaxy series Note 10, S 10 and Fold They can also enjoy this support.
The loading speed and stream will feel real in the crowded spaces in the cafes and malls where there will be wi-fi routers.
We don't find too much about this standard in the chapter. Dell launched at the end of 2019 the XPS 13 model with hardware that allows Wi-Fi 6, and HP came with Spectre X360 13 with the new generation of Intel Optimized processors for Wi-Fi 6. Intel Wi-Fi 6 chipset It is found on the 10th generation of Intel (Ice Lake) processors.
Routere with Wi-Fi 6
If you are the owner of a Wi-Fi 5 (802.11ac) router, you have no reason to upgrade to Wi-Fi. Most likely you have an iPhone 11 or a Samasung Galaxy Note 10 / S10, the only ones compatible with the new standard. Remember also that in a home with few connected devices, Wi-Fi 5 is sufficient. If you have to buy a new router, you can consider one with Wi-Fi 6, but it is limited compared to Wi-Fi 5. You will find some models from TP-Link, NETGEAR and ASUS On online stores, and prices are quite high.
At the CES 2020, several manufacturers have been announced who will launch Routere Wi-Fi 6 until the end of this year. So if you can still wait… You might save money on a sum of money.
