Wifi 6 What It Is And Why 2021 Is Its Year

What is Wifi 6 and why is 2021 its year? The question, more than spontaneous, deserves an articulated premise.

We talk a lot, often too much, about wifi 6, but why is this acronym so important for our lives?

What changes should we expect shortly? Let’s try to explain it with a concrete example: have you ever tried to watch a game streaming on your smartphone using the public wifi, perhaps present in a historic center or on a university campus? You have probably not even tried so far, since you already know that the outcome would be quite obvious: difficulty in taking the connection slowed down or unclear images, unstable connection, and so on.

Difficulties that increase our sense of frustration and that, in all likelihood, would soon lead us to switch to our cellular network, consuming the GBs supplied at a high price by our mobile operator.

The difficulties encountered are rarely induced by a malfunction of our endpoint but, rather, are determined precisely by the performance of the Wifi up to as we have known it so far. The prevailing standard today and current routers are not designed to work best in large and densely packed areas of devices, which greatly complicates our access to the desired content.

But even in our homes, very often, it is enough to move a few meters away from the router to see a noticeable decline in performance.

 
Wi-fi 6: A Punctual Solution To The Problems Of The Internet

The problem is that, as we know, we are now increasingly dependent on the Internet and the network: homes have become real Smart Homes, with many connected devices, from smart speakers to our TVs.

But also offices and industries are no less, with many devices that are connected to the network to increase productivity and business efficiency. Fortunately, we are in the midst of the Wifi 6 revolution, which arrives just in time to prevent this problem from becoming enormous and unmanageable.

In fact, what is Wifi 6? It is the latest wireless standard, initially known as 802.11ax, which was developed by the Wifi Alliance (an association which in turn brings together the main producers in the networking world) to meet the needs of users, starting from the boom we are seeing in video traffic, which inevitably absorbs more bandwidth.

Wifi 6, Speed, Reliability, And More

In this sense, the main strength compared to the previous standard (IEEE 802.11ac) is the net increase in connection speed, which goes from 6.9 Gbps to 9.6 Gbps. The transmission speed is also considerably higher (+ 25%), thanks to the 1024-QAM encoding. Furthermore, Wifi 6 can count on double bandwidth thanks to the use of 160MHz channels and the minimization of collisions with adjacent networks. There are also a whole other set of features of Wi-Fi 6, which greatly increase its reliability for users compared to previous standards.

Among these is the use of QAM (Quadrature Amplitude Modulation) 1024, which guarantees a 35 percent increase in bitrate.

The problem of latency and overload that we mentioned above is also considerably mitigated thanks to the OFDMA (Orthogonal Frequency Division Multiple Access) features, which allow a single Access Point to better manage even very high traffic peaks. Unlike the previous standard, the data transmission of each device is programmed simultaneously and in parallel.

The TWT technology (Target Wake Time also allows you to have better results from the point of view of energy efficiency and lower consumption, favoring a better battery life of client devices. Moreover, thanks to Wifi 6 it is possible to locate the people via wi-fi and Bluetooth, thus paving the way for new applications that span a whole range of vertical markets.

Not to mention that the Wi-Fi 6’s ability to instantly route traffic, even to devices at the ends of extremely crowded networks – will make it possible to enable the Internet of Things (IoT) revolution more completely and completely. In short, the technological characteristics of Wi-Fi 6 are destined to profoundly change our way of approaching the network and the digital world. In the next few years, we will enjoy better, faster, and more reliable Wi-Fi connectivity.

The Strengths Of Cambium Networks’ Wifi 6 Offer

This future is already present: 2021, in all probability, will be a fundamental year for the further diffusion of the standard: despite the consequences of the global pandemic, by the year about half of the devices marketed globally should be ready to accommodate Wifi 6.

Before that, however, comes the infrastructural aspect: for some months now, proposals from various Access point vendors already equipped with Wifi 6 have begun to appear on the market.

Among the first to have presented a range of devices there is certainly Cambium Networks: a distinctive feature compared to the competition is that all the Wi-fi6 devices of this vendor are conceived from a software-defined network perspective.

A peculiarity that guarantees enormous flexibility in the configuration phase and very high performance. Additionally, as certified by the independent Tolly Group testing and analysis laboratory, Cambium Networks WiFi 6 wireless access points outperformed major competitors in terms of performance and Total Cost of Ownership (TCO).

From a technical point of view, Cambium has paid great attention to the issue of security, thanks to the availability of dedicated sensors for threats, both for intrusion detection and intrusion prevention “.

Cambium’s Wifi 6 solutions are thus ideal for companies, office buildings, retail, schools, residential complexes, and smart cities, which can now handle simultaneous video streams and support more users than ever before. In addition to the actual technical characteristics, Cambium products are equipped with real features that greatly simplify the tasks of end customers, especially providers.
