We have at home an increasing number of devices connected to the Internet through wireless networks. The WiFi connection has become essential in our daily lives. The increase in devices and the arrival of new features, such as 8K resolution, requires updates.
Until now, the biggest novelty was WiFi 6E, a small revision of WiFi 6 that adds the 6 GHz band. We are going to explain what is new in this new wireless connection standard, compared to its predecessors.
Increased speed and bandwidth
Undoubtedly, the WiFi standard is great and has been adapting to the needs of the moment. For example, the WiFi 5 standard including the 5 GHz band that is focused on gaming. I’ve been at the time when gaming consoles and computers began to require decent wireless connectivity to play.
The WiFi 6 standard stands out for offering a speed of 10 Gbps for the 2.4 GHz and 5 GHz frequencies. On the other hand, this standard offers a bandwidth of 160 Hz per channel and a maximum number of connection flows of up to 8 devices . Somewhat later, WiFi 6E arrived, a small update that includes the 6 GHz band.
It should be noted that the WiFi 6E standard has not yet taken off as it is a minor update. Some have introduced it and others have ignored it.
Wi-Fi 7 takes a huge leap from the previous standard. The first thing that stands out is in offering a effective speed of 33 Gbps, which is triple that of the previous version. Also, the bandwidth pass to thes 320Hz and supports a connection flow of up to 16 devices. Natively implements the bands of frequency of 2.4 GHz, 5 GHz and 6 GHz.
Something you may not care about much is the upper modulation waveform. Basically, it is a technology that allows two independent signals to be transported through modulation. We went from having a 1024-QAM modulation in WiFi 6 to a 4096-QAM modulation on WiFi 7.
Ok, now explain it to me so that I understand
All these numbers and parameters, possibly, is the same as looking at Egyptian hieroglyphs: very beautiful, but you don’t understand anything.
The important thing about WiFi 7 is that it is designed, first of all, for video transmission in 4K and 8K resolutions. These two video signals contain a lot of information and are difficult to handle, so a solution is required for them.
Another key point is the number of devices that connect to a WiFi network, which is becoming more and more. A connection standard is required that allows so many simultaneous connections to be supported. This is especially important in public spaces such as bars, restaurants, libraries and other spaces where many people gather.
Finally, another of the notable improvements of WiFi 7 is in latency for gaming. Communication times between the computer and the router are reduced, something critical in online games. Having a high latency or ping supposes a delay in the actions that can result in the loss of the game. So this improvement is critical for online gaming.
