WiFi 6 isn’t yet mainstream on electronic devices, but the discussion has been already started for the Wi-Fi 7. According to the CNET report, V.K. Jones, vice president of technology at Qualcomm, says, “I’m excited about delivering a gigabit everywhere in your house, every nook, and cranny. You’ll be at the point where wireless is faster than wired.”

Subsequently, he shared some more interesting details regarding the WiFi 7. He technically divided it into three phases. Starting with the first phase, it will emphasize to improve the capacity of airwaves, which the European Union is likely to start by the next year. Afterward, WiFi 6 will be updated with faster speed by 2022 with eligibility providing more rooms to users upload and download bandwidth at faster speeds. Last and final stage is very crucial because it focuses to upgrade the WiFi standards. Currently, it is known for its technical name as 802.11be, which might end up being WiFi 7.

Expected Release Date of WiFi 7?

Even though WiFi 6 has the potential to evolve further in the next few years, we can only expect WiFi 7 to make its debut after 2024. These changes will come step by step as our requirements start increasing for the faster internet. Undoubtedly, a wider range of AR/VR technologies and self-driving vehicles dream only can be fulfilled after achieving a faster wireless internet speed compared to current industry standards.

How faster WiFi 7 is compared to WiFi 6?

Wi-Fi 6 can reach up to 9.6 Gbps, while, the speed of Wi-Fi 5 is 3.5 Gbps. It can be seen that the increase is still very obvious. Therefore, Wi-Fi 7 speeds expected to reach as high as 30 Gbps per second. Which means better streaming video, longer distances, and less congestion. For this new standard, the Wi-Fi Alliance has not yet been widely promoted.

A recent report published by Visual Networking Index, IP video traffic will account for 82% of total IP traffic worldwide by 2022. That’s more than the 75% share in 2017. The annual growth is predicted to 26 percent from 2017 to 2022. And monthly traffic is expected to be 50GB per capita by 2022. Live web video will account for 17% of Internet video traffic. Overall, the dominance of video traffic will force Wi-Fi 7 to take over the Wi-Fi 6 standards.

The latest three Wi-Fi standards are IEEE 802.11n, 802.11ac, and 802.11ax respectively. These are certified as Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6. Therefore, 802.11be is a powerful candidate for receiving Wi-Fi 7 tags. The Wi-Fi 6 can use multiple RF bands from 1GHz to 7GHz, including the 2.4GHz and 5GHz bands currently used by Wi-Fi, and the transmission speed is 3-4 times faster than the Wi-Fi 5 standard.

Furthermore, Wi-Fi 6 also supports OFDM up to 1024QAM and multi-user multiple-output technology. After using the OFDA, the wireless bandwidth has theoretically increased by a factor of 10 times, indeed, it is only 4 times faster than its predecessor. With the acceleration of 5G network commercialization, Wi-Fi 6 will become more and more popular.
