Advantages of Wi-Fi 6 campus network praised by DUFL teachers and students

1. Advantages of Wi-Fi 6 campus network praised by DUFLteachers and students "The campus network signal is better and the network speed is faster!" The speed is too fast. I hope it can be slower. " This is the information from the official WeChat page of Dalian Foreign Studies University. In a recent article published by its WeChat official, students were excited about the news that the second phase of campus wireless network was officially opened. They are very excited because the long-awaited Wi-Fi 6 has finally arrived. The Phase II campus network of Dalian Foreign Studies University covers all indoor public areas such as classrooms, canteens and complex buildings, as well as outdoor public areas such as basketball courts, tennis courts and teaching buildings, to achieve full coverage of wireless campus network. The speed of campus network is accelerated and the cost is reduced. The bandwidth was increased from 2.4Gbps to 5.7Gbps, and the cost was adjusted from 20 yuan to 12 yuan, providing better network services for teachers and students. Wireless devices of wireless campus network phase II support Wi-Fi 6 (802.11ax). Ultra-high performance can easily meet the diverse application needs of campus classrooms, canteens, libraries, etc., and provide better network services for teachers and students. The continuous innovation of classroom applications has greatly improved the requirements for Wi-Fi With the development of information technology in colleges and universities, Dalian Foreign Studies University is paying more and more attention to the construction of wireless network in colleges and universities, and plans to build a comprehensive campus Wi-Fi, use modern information technology to promote educational reform, and realize the leapfrog development of educational innovation. In 2015, the school began to build the first phase of wireless campus network. Ruijie's simple wireless AP solutions are deployed in outdoor areas, offices, teaching areas and dormitories, making Dalian University of Technology the first university in Dalian to use Wi-Fi 5 (802.11ac) wireless coverage. In 2018, with the continuous promotion of classroom reform, the demand for teachers and students to use digital products for interaction in the classroom is growing, and the application of high-definition classroom recording is also increasing. Therefore, wireless network needs to support the change of teaching mode. Especially for language teaching, teachers have an urgent

2. need for high bandwidth classroom teaching applications such as IPTV and HD video. They also asked students to use their laptops to access video resources through wireless networks. Therefore, we should ensure that each student has a certain bandwidth. In addition, in VR classrooms, offices, libraries, conference rooms, lecture halls and other places, wireless networks are also needed to meet the requirements of high concurrency, high bandwidth and low latency in high-density scenarios, and to increase the flexibility and convenience of education reform. Based on the above requirements, the second phase of DUFL wireless network construction was officially launched. The new Wi-Fi standard in the second phase In the early preparation stage of the second phase of wireless network planning, the latest Wi-Fi 6 standard was officially released. Based on the advantages of Wi-Fi 5 (802.11ac), the coding and modulation enhancement of Wi-Fi 6 greatly improves the spatial reuse efficiency, enabling each access point to communicate with more devices at the same time, thus achieving higher density deployment, lower latency, wider coverage and higher speed. In addition, its improvement in low power consumption is particularly friendly to active Internet of Things devices in intelligent campus. At the initial stage of construction, the school and Ruijie Network jointly studied the feasibility of the Wi-Fi 6 solution, taking into account the AP performance and capacity, terminal access capacity, unified management of Phase I and subsequent expansion of the Internet of Things. After passing the field test, Ruijie Wi-Fi 6 (802.11ax) RG-AP850-I is adopted. The AP adopts a three-RF design with access speed up to 6.8Gbps, supports uplink speed up to 3gbps, and can expand other modules such as the Internet of Things, greatly enriching the campus application scenario. While meeting the bandwidth needs of teachers and students in classroom teaching, it also ensures that the solution will remain in the leading position in the next five years. Wi-Fi 6 wireless campus network can be optimized through the Ruijie WIS wireless AI cloud platform to provide the ultimate experience for teachers and students in each teaching scene.
