4 technologies that explain why you should use WiFi 6


When we talk about technology news, it is inevitable to assess them with adjectives such as fast, efficient, stable, intelligent or intuitive. But behind those adjectives there is functions or features that often have names or acronyms that are difficult to understand. It is the case of Wi Fi protocol. If it’s hard to remember that WiFi stands for Wireless Fidelity, its WiFi 6 version is loaded with unique technologies.

In practice, we must stay with WiFi 6 is better than its previous version in aspects such as speed, energy efficiency, simultaneous connections, latency or signal range. But if you want to know why, there are acronyms such as MU MIMO, OFDMA, QAM or TWT, among others.

So if to really understand why you should start thinking about upgrading your fleet of electronic devices by devices compatible with WiFi 6, such as the Smart Wi Fi 6 Router of Movistar, here is a review of four of the most outstanding features of the WiFi protocol in the form of technical acronyms.

MU MIMO and WiFi 6: everything connected

MU MIMO is an Anglo Saxon acronym that in Spanish means “Multiple User Multiple Input and Multiple Output”. This technology is also called new generation AC either AC Wave 2. It is used for the WiFi router to communicate with other devices simultaneously. Something essential today, since we have at home or in the office a large number of devices of all kinds that require internet access to function.

Actually, the MU MIMO feature was already available in the WiFi 5 protocol. Its predecessor, MIMO, was born with WiFi 4. But in WiFi 6 it incorporates improvements in order to meet the demand for simultaneous connections in any average home: TV, phones, computers, tablets, game consoles, smart lighting, smart appliances, speakers, etc.

In the words of manufacturers such as D Link, MU MIMO technology “transmits data to multiple devices simultaneously, rather than sequentially as is the case with the current standard.” And this happens thanks to the possibility of generate up to 4 data streams simultaneous.

OFDMA: better performance

The acronym OFDMA stands for Orthogonal Frequency Division Multiple Access. Translated into Spanish, Orthogonal Frequency Division Multiple Access. And to understand us, it is an improvement of an earlier digital modulation technology known as OFDM. Or put another way, thanks to OFDMA, WiFi 6 devices allow a improved network performance.

As the manufacturer Asus explains on its help page, OFDM and OFDMA technology divides the transmitted data into small packages. This makes it easier and simpler to transport information between devices. In turn, OFDMA subdivides a channel into smaller frequency allocations known as subcarriers. The result is that they can send and receive more data to multiple devices at once.

1024 QAM over Wi Fi 6

In Spanish it is known as QAM Modulation or Quadrature Amplitude Modulation, in English Quadrature Amplitude Modulation. This technology is all about sending signals. Specifically, it carries two independent signals, through digital modulation, both in amplitude and in phase, of a carrier signal. And although it is not a novelty in itself of the WiFi 6 protocol, the novelty is in the speed that it reaches: 1024 QAM compared to 256 QAM of WiFi 5. In practice, it allows to reach multi gigabit speeds.

Otherwise, the use of QAM modulation makes the more stable signalagainst interference, reduces the power consumption of the device, can send more information simultaneously, and the transmission is of better quality.

TWT: less power consumption

The acronym TWT stands for Target Wake Time. We could translate it as Destiny Activation Time. Its main advantage is that it makes the WiFi protocol consume less energy. which translates to more battery life from your smartphone or laptop. The reason is in the way the device connects to the available WiFi network.

Originally, a device connects every so often looking for active WiFi connections. But with Wi Fi 6 and TWT technology, the device accesses the Wi Fi connection only when necessary by agreeing with each other. Which translates into fewer connection attempts and less energy consumed.

These are four of the most prominent acronyms or technologies of the WiFi 6 protocol, but they are not the only ones. As usual, WiFi 6 maintains most of the features of previous versions of this wireless connection standard. The most popular is WPS, acronym for WiFi Protected Setup or WiFi Protected Installation. It is used to connect devices to your router by pressing a button. You will find more information in this article.
