Notebooks, smartphones, tablets, smart devices and TVs as well as all sorts of clever solutions require an Internet connection via Wi-Fi. Due to the increase in the number of such devices in our homes, routers no longer cope with their tasks, as the Wi-Fi the most advanced standards allow to maintain at the same time a very limited number of clients. Как оказалось с этим недостатком и призван справится стандарт Wi-Fi 802-11ax. What other benefits it provides? This will be discussed in this article.
Wi-fi ax – так называется очередной стандарт беспроводной связи, which must meet the requirements of users requirements today. Must provide reliable connections and high speed a large number of devices connected to the internet simultaneously. В этой статье приводятся все известные на сегодняшний день сведения о стандарте Wi-Fi 802-11ax.

What is the wi-fi ax?
Wi-fi ax (or IEEE 802.11 ax) – is the latest wireless standard (previous are wi-fi ac, n, g, b и a). Like previous works on the frequency bands 2,4 GHz and 5 GHz, however much faster, and above all, meet the modern realities, which at the same time with laptops, tablet and smartphone connected to the router as:
- lighting;
- teapot;
- washing machine;
- CCTV Cameras;
- alarm system and much more.
Как следует из недавних исследований проведенных Interteam.com.ua число устройств, connected to the Internet, may increase in the average apartment in 2022 from the current year 10 to 50. This will lead to the fact that many of them will fight for his place in a dedicated channel, that is why it is so important that in the latter there is as much space, что и должен обеспечить стандарт WiFi ax.
The first devices, supporting the new Wi-Fi standard is slowly appearing on the market, и в ближайшем будущем должны стать стандартом. Что можно ожидать и какие будут реальные преимущества для пользователей?
What will be the speed wi-fi ax?
Not hard to guess that not only increased capacity of channels in standard WiFi ax, comparing it with the previous generation, it will provide the speed an order of magnitude greater. Напоминаем что стандарт ac обеспечивает скорость передачи данных на уровне 1,3 Gb / s, а ax в идеальных условиях характеризуется скоростью до порядка 10 Gb / sec. This means that in typical cases (next room) он без проблем обеспечит скорость до 1,5 Gb / sec, that is a great result. But this will not be the most important innovation.
High speed wi-fi ax that's not all
The most significant advantage of the IEEE 802.11 ax will be a huge bandwidth, through which a very large number of devices in a small area without any obstacles will have a very fast internet access. briefly, in conference rooms, на вокзалах или стадионах быстрый доступ к интернету через Wi-Fi станет нормой. How is it possible?
As is the case with the wi-fi ac can be used 4 MIMO stream (multiple input/multiple output), but this time using OFDMA technology (orthogonal frequency division multiple access). Last (It is also one of the biggest advantages LTE) It allows each radio channel is divided into several tens or even hundreds of subchannels (working on a few other frequencies). В результате удается достичь до 10-кратного увеличения спектральной эффективности.
Simply put: Each user will have their subchannel, поэтому не будет ждать очереди для использования интернета. В свою очередь кодирование 1024 QAM (also used in ax) It increases the amount of data of each data packet.
Another advantage, that should come with wi-fi ax, будет увеличение времени работы устройств от аккумуляторной батареи. Это стало возможно благодаря TWT (target wake time). How it works? Дело в том что подключение гаджета к роутеру не будет осуществляться в момент когда вы выключили смартфон и поставили в карман.
Compatible wi-fi ax with previous standards
This standard is the result of evolution, and not new, поэтому не возникает никаких проблем с совместимостью. Simply put: wi-fi ax совместим с более ранними версиями 802.11. Of course, the use of a smartphone with the old standard does not allow you to use the advantages of the latest technology.
