wifi 6 coverage scheme for campus -ag贵宾会

"the campus network is really good, and it's fast! i just hope that he can walk a little bit slower." this is a message from the official weibo of dalian university of foreign languages. in his official micro-article issued not long ago, the news of the students about the official opening of the second phase of the campus wireless network can be described as "great and popular."

because, the long-awaited wi-fi 6 is finally here!

it is reported that the second phase of the university’s campus network covers all classrooms, canteens, comprehensive buildings and other indoor public areas of the school, and covers outdoor public areas such as basketball courts, tennis courts, and teaching buildings to achieve full coverage of campus wireless networks. the campus network speeds up and costs are reduced. the export bandwidth has been increased from 2.4gbps to 5.7gbps, and the cost has been adjusted from 20 yuan to 12 yuan, so as to provide teachers and students with better network services. the wireless equipment of the second phase of the campus wireless network supports wi-fi 6 (802.11ax). the ultra-high performance can easily cope with the diverse application needs of classrooms, canteens, and libraries on campus, providing teachers and students with a better network experience.

classroom applications continue to innovate, and the demand for wi-fi has increased significantly.

with the development of school informatization, dalian university of foreign languages pays more and more attention to the construction of the school's wireless network, plans to build a full range of campus wi-fi, comprehensive and in-depth use of modern information technology to promote educational reform, and achieve leapfrog development of educational innovation.

in 2015, the school began to construct the first phase of the wireless campus network. through yinghua's minimalist wireless solution, scene-based deployment was carried out for outdoor areas, office areas, teaching areas, and dormitory areas. it became the first wi-fi 5 in the dalian area at that time. (802.11ac) covered colleges and universities.

in 2018, with the continuous advancement of classroom reforms, the demand for interaction between teachers and students in the classroom using digital products has increased, and the application of high-definition classroom recording has increased, and wireless networks need to support this reform of the teaching mode. in particular, in view of the characteristics of "language" teaching, teachers have an urgent need for high-bandwidth classroom teaching and applications such as iptv and high-definition video. students will also be arranged to use their own laptops to access the wireless network to access video resources. each student needs a certain bandwidth guarantee.

in addition, in vr classrooms, offices, libraries, meeting rooms and lecture halls, wireless networks also need to support a large number of terminal concurrency, high bandwidth, and low latency requirements in higher-density scenarios, and help teaching reforms to be more flexible and convenient. based on the above requirements, the second phase of the wireless network construction of dalian university of foreign languages was officially launched.

the second phase of the plan is oriented to new standards and wi-fi get new skills

in the early stage of the school's preparation for the second phase of the wireless network design plan, the latest wi-fi 6 standard was officially launched. the standard is based on the advantages of wi-fi 5 (802.11ac), and further through the enhancement of coding and scheduling methods, the efficiency of spatial multiplexing is greatly improved, so that each ap can communicate with more devices at the same time, allowing greater density the deployment of equipment, lower delay, longer coverage, higher speed. at the same time, its improvements in low power consumption are particularly friendly to those active iot terminals in the construction of smart campuses.

in the early stage of construction, the school began to fully demonstrate the feasibility of the wi-fi 6 solution with yinghua networks, taking into consideration the aspects of ap performance and capacity, terminal access capabilities, unified management in the first phase, and subsequent iot expansion. after passing the field test, the yinghua rg-ap850-i based on the wi-fi 6 (802.11ax) technical standard is finally adopted. the device adopts a tri-band design, and the access speed can reach 6.8gbps. a single ap supports bundled uplink speed. 3 gbps, it can also expand other modules such as the internet of things, which greatly enriches the application scenarios on campus. while meeting the bandwidth requirements of teachers and students in classroom teaching, it also ensures the advanced nature of the program in the next five years.

the wi-fi 6 campus wireless network deployed this time is also optimized through the yinghua wis wireless ai cloud platform, providing the ultimate experience for teachers and students in each teaching scene.

"fast, broad and many", wireless campus "666"

seeing that the school’s wireless network was upgraded with new equipment, some students happily left a message on their official wechat account: “i’m no longer afraid of the embarrassment of waiting in the cafeteria for payment, or the anxiety of not being able to open wechat pictures in the second education. and i heard that it can be cheaper. !"

where is the wi-fi 6 network that allows teachers and students on campus to "popularize"?

the first "6" is "fast". compared with wi-fi 5, the network bandwidth is increased by 4 times, the number of concurrent users is increased by 4 times, and the transmission delay is reduced by more than 60%. it can easily cope with the ultra-large bandwidth, ultra-high-density access, and ultra-low latency requirements of classrooms, canteens, and libraries. the application scenario provides a better network experience for teachers and students.

the second "6" is "guang". the second phase of the campus wireless network covers all classrooms, canteens, comprehensive buildings and other indoor public areas of the school, and covers outdoor public areas such as basketball courts, tennis courts and teaching buildings, and strengthens the playground, the surrounding areas of mingyang lake, and the inner ring road. the signal coverage strength. the school has achieved full coverage of the campus wireless network, and students’ internet access is no longer confined to the apartment, and the campus wireless network can be connected to all areas including office areas and teaching areas.

the third "6" is "more". the second phase of the campus wireless network adopts a high-density deployment plan in densely populated places such as classrooms and canteens. the network capacity is designed according to 80 people using one wireless device, and the cluster deployment ensures that every teacher and student can get the best network use. quality.

in terms of application, the campus wireless network deployed this time continues the first phase of use mode, and through non-inductive access, seamless roaming of teachers and students in the wireless coverage area of the campus network is realized. at the same time, the "weidawai" official account service has been optimized again, allowing detailed queries on the progress and details of common campus network services such as network fee recharge, traffic query, self-service suspension, package change, and troubleshooting. the school also uses the second phase of the campus wireless network to flexibly allocate network resources based on the sdn function, and is at the forefront of dalian universities.

the successful deployment and trial operation of the wi-fi 6 wireless campus network has helped dalian university of foreign languages become a new benchmark for campus wireless networks in universities across the country. a high-speed, high-concurrency, high-security, and anti-interference wireless access network will help dawai's education informatization capabilities to achieve a further leap.
