Wi-Fi 7 domestic standard is about to be implemented! The Ministry of Industry and Information Technology solicits opinions on equipment approval, and the measured network speed reaches 4.3Gbps

On June 2, it was reported that the technical standard IEEE 802.11be (Wi-Fi 7), the next generation wireless LAN, has not yet been implemented in China. Once the relevant standards are officially implemented, a large number of products will be launched on the market.

According to the Ministry of Industry and Information Technology's official website on June 1, Wi-Fi 7 standards are expected to be implemented soon. The government has officially released a public notice for comments on the "Notice of the State Radio Office on the Technical Requirements and Test Methods for the Approval of New Models of Wireless LAN Equipment Adopting the IEEE 802.11be Technical Standard (Draft for Comments)".

The draft for comments points out that in order to guide the development of the wireless LAN industry, standardize the model approval of radio transmitting equipment of wireless LAN equipment (hereinafter referred to as model approval), and promote the compatibility and sharing of wireless LAN with 5G, Beidou, Internet of Vehicles and other services, it is proposed to add relevant technical requirements and testing methods for wireless LAN equipment that adopts the IEEE 802.11be technical standard in the model approval test.

IT Home learned from the draft for comments that Wi-Fi 7 devices are expected to require testing of the multi-link operation (MLO) feature with an operating frequency range of 2400-2483.5MHz, 5150-5350MHz and 5725-5850MHz. Through chip-level multi-channel connections, throughput can be increased, making the network faster and avoiding freezes.

The test of Wi-Fi 7 devices also introduced 4096-QAM, which increased the network transmission capacity from 10 bits to 12 bits per time, improving the throughput performance by about 20% compared to Wi-Fi 6.

In fact, many mobile phones and routers have announced support for Wi-Fi 7 and used this as a selling point, such as the Xiaomi 13 series, which claims to take only 2.9 seconds to download a 1GB movie.

In addition, Huawei conducted deployment tests on Wi-Fi 7 APs at the Network and Information Center of Southeast University in April, and the actual measured single-terminal rate of Wi-Fi 7 exceeded 4.3 Gbps.
