Construction scheme of Wireless campus network in Dalian Institute of Light Industry

The information construction in the field of higher education in our country has been carried out in a steady and orderly manner, and after several stages of development, such as "Single Machine" and "networking", the information construction of higher education in China has achieved a phased result. In terms of basic construction, campus network has been opened, computer centers, teaching resources centers, digital laboratories have been built, in the specific application, the campus Web site to improve the efficiency of information sharing, OA system for teachers to provide a cooperative office platform, Digital library has changed the spread of knowledge and use of the way, The card system gives the teachers and students a great convenience in life. On the basis of the above prophase construction, nowadays universities and colleges have been seeking to push the informatization construction to a deeper level. For the information builders in colleges and universities, how to make full use of the previous stage of information construction results, how to build a more close to the application of teaching, it is their current stage of the task of urgent need to be solved.

In this regard, one of the oldest colleges in northeastern China, Dalian Institute of Light Industry, through the use of Ruijie Network wireless solutions and related equipment, to create an "efficient, safe, reliable" wireless campus network, the Wireless campus network to make full use of the Dalian Institute of Light Industry, the first phase of information construction results, For the vast number of teachers and students access network, application network has provided a great convenience, and effectively promoted the development of teaching activities of various disciplines. In general, the wireless campus network is simple in structure, reasonable in layout and practical in economy, and it is of great significance and popularization value in similar universities.

"The book" many, expect not to be "line" system

Dalian Institute of Light Industry is the first high school of light industry in northeast China. As the training base and research and Development center of northeast China's consumption industry talents, Dalian Institute of Light Industry attaches great importance to the construction of basic teaching environment. Especially in the information construction, the school always walk in the forefront of the northeastern universities. In the network construction, as early as a few years ago, Dalian Institute of Light Industry has been working with Ruijie to build a whole campus wired Ethernet which can connect each campus. On this basis, Dalian Institute of Light Industry has developed and deployed a series of web-based application Systems, which have achieved good results in practical application and improved the basic teaching environment of the whole school effectively.

In recent years, with the increasingly mature campus information environment, Dalian Institute of Light Industry's computer terminals, especially lightweight and flexible notebook computer penetration began to rise. The survey showed that the popularity of notebook computers in Dalian Institute of Light Industry is now more than 18%, with nearly 1 people using laptops in almost every 5 persons. As a portable mobile computing device, notebook computer combined with wireless network can be used to maximize the characteristics of the device. To this end, with the increasing number of notebook computers, Dalian Institute of Light Industry, teachers and students of the wireless network increasingly louder, the general hope to be able to get rid of the network cable as soon as possible, anytime, anywhere to go online teaching and learning.

Dalian Institute of Light Industry's relevant leadership in the in-depth understanding of the application of information in the new situation, in full listening to the vast number of notebook computer users on the basis of the unanimous view: wireless network with convenient, fast features, build wireless network can give full play to the role of mobile computing terminals, can improve the utilization In order to improve the depth and breadth of information application, it has a positive influence on teaching in every aspect and level. Based on the above considerations, Dalian Institute of Light Industry decided to be based on the current demand for future applications, building a high-speed, broad coverage, easy to manage the safe and reliable campus wireless network.

Join hands Rui Jie, quell network fence

Based on the previous good cooperation experience, and considering that Ruijie and the education industry has a long-term in-depth cooperation in the Wireless campus network construction has a mature product and rich experience, Dalian Institute of Light Industry decided that the campus wireless network construction again commissioned Rui Jie to carry out.

Dalian Institute of Light Industry has a total of nearly 10,000 teachers and students, the school has a total of 3 campuses, the total area of 1036 acres. Taking into account the Dalian Institute of Light Industry has many users, density, campus relatively independent, relatively concentrated building features, Ruijie decided based on its ace wireless products ――rg-p-780 Dual dual-frequency three-mode high-speed wireless access, for the Dalian Institute of Light Industry to build campus wireless network. According to the plan, Dalian Institute of Light Industry needs the wireless network area mainly divides into the office teaching area, the experimental building area, the dormitory area, the football field and the stadium hall, the outdoor leisure square, the library, the International Exchange Center and so on several parts. In the above area, Rui Jie according to the region's topography, building distribution and the estimated number of users, the density of appropriate, without leaving a corner of the deployment of the rg-p-780 wireless access device.

Institute of Light Industry the location of proximity to the airport, there is a problem with the airport wireless harmonic interference, and has been in the 98 anniversary of the college during the balloon Lightning Incident, the wireless environment complex and bad. Ruijie network using rg-p-780, for high-speed wireless transmission, a wide range of signal coverage, long-distance wireless interconnection requirements for high-power operation-level wireless access point product settings, and also support the 2.4GHZ and 5.8GHz 802.11a/b/g standard protocol, In support of coverage mode and wireless Network Bridge mode, can achieve 108Mbps high-speed transmission, can fully meet the Dalian Institute of Light Industry high density of the needs of the Internet.

RG-P-780 uses the dual high-power built-in two-way amplifier design, the larger transmission power with the built-in or external antenna, can easily penetrate the Dalian Institute of Light Industry many buildings, so as to ensure the transmission of the signal in the indoor and outdoor effects. In the manufacturing process, rg-p-780 adopted a high-quality waterproof, flame-retardant shell design, can effectively avoid indoor and outdoor bad weather and environmental impact, can be highly adapted to Dalian, the northern city of winter cold weather. In terms of network security, RG-P-780 supports 32 802.1Q VLAN partitions, each of which can enable encryption and authentication separately, allowing users of the Dalian Institute of Light Industry to be divided into different campus network access rights according to their identities. In terms of billing, rg-p-780 can integrate with the campus wired Ethernet billing system built by Dalian Institute of Light Industry, and jointly implement the 802.1X certification billing to realize the unified management of billing.
