What is Wi-Fi 7, which is more powerful than Wi-Fi 6?

As we all know, Wi-Fi 6 can be said to be one of the hottest buzzwords in the current technology field. Now that Wi-Fi 6 is just beginning to become popular, scientists have already begun to promote Wi-Fi 7.

It is reported that the speed of Wi-Fi 6 can reach 9.6 Gbps, while the speed of Wi-Fi 5 is 3.5 Gbps, which shows that the improvement is still very significant. However, the speed of Wi-Fi 7 can reach up to 30Gbits per second, which means that it can provide better streaming video, cover longer distances, and reduce congestion. For this new standard, the Wi-Fi Alliance has not yet widely promoted it.

At present, the three latest Wi-Fi standards are IEEE 802.11n, 802.11ac, and 802.11ax, which are certified as Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6, respectively. Therefore, 802.11be is a strong candidate to receive the Wi-Fi 7 label.

In the future, this technology will not only transmit data faster, but it will even be able to detect the user's physical location and breathing rate, etc. We can imagine the future applications of this technology. For example, when an elderly person is alone at home, if a Wi-Fi with the above functions is installed in her house, we can know whether her behavior is normal and whether she has fallen. But there is no guarantee that Wi-Fi 7 will add human detection capabilities when it is released. Not to mention, it will take at least four years for the next Wi-Fi standard to be released. Nevertheless, the possibility of allowing home networks to detect human presence is still significant because it can open the door to more innovations.

Such a system can even be used to automatically open doors. When you return home, the home Internet will detect your presence and combine this data with the signal from the device you are wearing or the camera system, and it will automatically unlock the door when you walk up the stairs. It can be said that we have truly entered the era of the Internet of Everything.

Finally, before this happens, the IEEE needs to ensure that these rights are strongly protected, including for individual privacy, and that complex Wi-Fi networks are protected from intrusion. The IEEE has assigned a dedicated team to address privacy issues in the new Wi-Fi standard.
