Wi-Fi 7 will allow transfers of up to 40 Gbps


What is Wi-Fi 7? It corresponds to IEEE 802.11 , which will release a new revised standard IEEE 802.11b. This is the successor to the Wi-Fi 6 / 6E, the update brings only a limited improvement in the speed of the network. The substantial difference from Wi-Fi 6 to Wi-Fi 7 again focuses on speed, with data transfer peaks of up to 40 Gbps .

To achieve such a high speed, Wi-Fi 7 also adopts a large number of new technologies, and further expands the bandwidth (up to 320 MHz), using the updated 4096-QAM modulation technology to increase the speed, it also takes advantage of in an innovative way, new technologies such as Link and Enhanced MU-MIMO. In addition to speed, the signal and delay of Wi-Fi 7 are also a cause for concern, in fact there are also corresponding technical solutions in Wi-Fi 7, for example, “Preamble Puncturing” can solve the problem of signal interference. Multi-chain Multi-channel operation (MLO) technology allows devices to cover different frequency bands and channels, reducing latency and improving reliability.

Another major improvement to Wi-Fi 7 is that this can allow multiple users to connect to the internet at the same time , as usual by decreasing the speed of Wi-Fi when multiple users connect to the network, but the good news is that now a single channel in Wi-Fi7 can accommodate more than 500 individual users, which makes the connection absolutely performing. The improvement of Wi-Fi7 is all-round, the theoretical bandwidth can already replace the wired network / interface and the signal and delay have been further improved, in addition, now more devices can connect to the network while maintaining its high speeds.

The ultra-high-speed, low-latency capabilities of Wi-Fi 7 not only work for cell phones and routers, but also prepare for expansion into other fields, such as XR Reality technology. These technologies have high demands on delay and extremely high latency. A high refresh rate requires a high-speed network, and Wi-Fi7 can meet those requirements.
