The capabilities of WiFi are becoming more and more powerful. Two or three years ago, WiFi6 increased the network speed to gigabit, becoming the main solution to achieve “double gigabit” in cities and homes; Now, the more capable WiFi7 is also gearing up to debut, and it is expected that in November 2023, a batch of products will be listed for the completion of standardization work WiFi7. For the future of WiFi7, a considerable number of people in the industry are optimistic that WiFi7, which “loads” many new features, will bring a new communication technology revolution. Can WiFi7 hold such high hopes?

What are the new features and uses of WiFi7?

At the recent Ruijie all-scene WiFi7 solution conference, Shi Jiangtao, product director of Ruijie Network wireless Product Division, believes that in the current wireless network basically covers the business network, WiFi7 because of its single technical specification iteration, subversive improve wireless use efficiency and user access experience, will become the key to open efficiency change in multi-industry scenarios.

WiFi7 core technology overview

As the WiFi protocol continues to evolve, the capabilities of WiFi7 have further evolved compared to the previous generation. The theoretical value of WiFi7 network speed can reach 46Gbps, which is 4.8 times that of the previous protocol. At the same time, thanks to MRU(maximum receiving unit) and leading code punching technology, WiFi7’s anti-jamming ability has also been greatly improved. The latency of WiFi7 can also be reduced by 90% compared to the previous generation, and the reliability can be improved by 100%.

Today’s wireless networks are used in production and complex business scenarios, enabling enterprise efficiency change and digital transformation. After the arrival of WiFi7, WiFi will further integrate with the Internet of Things and mobile communication network to provide better and inclusive wireless services; In the home, education and entertainment scenes, WiFi7 will support 4K/8K video and XR technology to build a new network experience of human-computer interaction and virtual and real integration. In industrial Internet and enterprise applications, WiFi7 will also help improve the quality and efficiency of core services with its disruptive performance rate.

Do capability mining for WiFi7

Although WiFi7 is better in performance, how to get the actual effect of these performance in the application, how to really improve the experience, but also need a technical ability to become a solution mining process.

In the office scene, the design company is often hundreds of people in the design of drawings, while the need to collaborate with each other, during which a large number of wireless screen casting. Different design branches will interact with each other on a certain design concept through screen projection technology, which has great requirements on delay and speed. Especially centralized office, centralized Internet time, how to improve the office experience? In the case of multiple people simultaneously attending video meetings in the company’s internal network meeting, can the smooth flow of these videos be guaranteed?

In the production scenario, there are about 100 AGV cars in the 5000 square meters logistics warehouse that is unattended for 7×24 hours. In the case of the speed of these cars at 1.5 meters per second, how to achieve no delay and no lying down?
