Wi-Fi 7 (IEEE 802.11be) is the next-generation standard from the Wi-Fi Alliance that defines new features. Wi-Fi 7 builds on Wi-Fi 6E (uses the 6 GHz band) and increases data rates through the use of 320 MHz channels. 6G + 320MHz (Double Width) When running immersive applications (such as VR/AR), previous Wi-Fi network standards inevitably encounter congestion and low quality of service. To achieve a higher throughput, Wi-Fi 7 will support the 6 GHz frequency band and extend new bandwidth modes, 320 MHz, or non-contiguous 160+160 MHz. 4K-QAM (Lower Latency) The highest-order modulation supported by Wi-Fi 6 is 1024-QAM, which allows each modulation symbol to carry 10 bits. However, Wi-Fi 7 adopts 4096-QAM so that each modulation symbol can carry 12 bits to further enhance peak rates. With the same transmission, 4096-QAM in Wi-Fi 7 can achieve a 20% rate increase compared with 1024-QAM in Wi-Fi 6, to achieve higher efficiency while watching Ultra HD 8K video. 16×16 MU-MIMO (Higher Capacity) Wi-Fi 7 increases the number of spatial streams from 8 to 16, increasing the twice number of theoretical physical transmission rates compared with Wi-Fi 6. With more data streams of APs, Wi-Fi 7 meets the growing traffic demands, and

From July 27 to 29, the 9th Internet Security Conference (ISC 2021) was held in Beijing China National Convention Center. The conference lasted 3 days, and 9 summits and over 30 sub-forums were held. As a cybersecurity industry gathering, ISC 2021 received unprecedented attention. Official statistics showed that people attending the conference surpassed 40,000 person-times as of 14:00 on July 29 and the number of related topics on Weibo exceeded 350 million, setting a record high. However, the network pressure behind these numbers was unimaginable. On account of Ruijie’s good reputation in 2019, 360 Group entrusted the network guarantee of ISC 2021 to Ruijie, which became the sole network supplier of ISC 2021. ISC 2021 was held in Beijing National Convention Center and this was the first time for Ruijie to build and guarantee a network here. It was a great challenge to build a new network with high reliability, high redundancy, and high security within a short period of time. After 7 days × 15 hours of intensive preparation and implementation, Ruijie 7-member team completed the network construction and guarantee for ISC 2021 very successfully. The network delivered by Ruijie had no failures nor interruptions during the conference. It

On the afternoon of October 22 afternoon, sponsored by China’s Security Protection Product Association, the 2018 Security Expo, the 7th innovation product promotion and the award ceremony jointly undertook by China Security & Protection magazine and PCI-Suntek Technology Co Ltd were successfully held in the C hall of Kuntai Hotel. The related enterprises, experts and representatives of award winners and the news media, more than 200 people attended the conference and award ceremony. The event was hosted by Zhang Zhongxiao, secretary general of China Association of Safety Products Industry. The leaders and guests attending the award ceremony include: Wang Yanji, chairman of the China Association Of Safety Products Industry; Tan Xiaozun, former secretary of the party committee of the scientific and technological information bureau of Ministry of Public Security; Gu Jianguo, Jin Xiufeng, vice chairman of the China Association Of Safety Products Industry; Zhang Zhongxiao, Secretary General Of The China Association Of Safety Products Industry. A grand award ceremony was held, among which the “Super Six Types of Digital Communication Cables With New Structure” independently developed by Potel cable group was awarded as “Outstanding Innovative Product” at the China International Public Security Product Expo in 2018. Potel group is located
