Keywords Large data can through

In the past two years, with the advent of the cloud era, the word large data (Bigdata) has been mentioned over and over again, and people use it to describe the vast amount of data and the technology that comes with it, the internet generates billions of data every day, tens of thousands of tweets per second, thousands micro-communication, The supermarket uses the big data to carry on the customer consumption behavior analysis, bundling the originally unrelated "diapers" and "beers" into a real-time pricing of goods on the basis of inventory and demand; Wall Street is selling stocks on the basis of popular sentiment; The Los Angeles Police Department and the University of California have collaborated to use large data to predict the occurrence of crime; Even domestic such as Baidu and other Internet companies also use large data technology developed such as Baidu Index applications. The importance of the data has gradually been recognized by the world, some people compare it to gold, oil, and even someone cloud "at that time, a huge amount of data appear in front of, what is a spectacular scene?" Watching all this in the background, would it be close to the feeling of God looking down at the spark

For the university campus, the data is exploding, data generation is also diverse, for information systems, both the school's business systems such as personnel, finance, education, assets generated by the structured data, as well as multimedia teaching and other unstructured data generated, while students, teachers, More and more information is automatically collected by visitors, such as through various social media and even communication software, to share their ideas and interests. Especially with the campus wireless network and the rapid development of mobile Internet, terminals, a large number of apps rich in the campus wireless network how to use large data technology to better provide services for the general teachers and students, as well as the school to provide better decision-making basis, has become the campus wireless network in the future development trend.

Unbounded Management

Campus has a wide range of terminal PCs, ipads, iphones, and terminal brands are also diverse, Apple, Samsung, Millet; Even the operating system is also various, different systems, terminals of wireless networks, business systems support is different. Analysis of the Terminal brand, type of ratio, so that the school in the development of the business system to carry out the progress of control (first development accounted for more than a large platform), different terminal platform for the difference between the adaptation and the students, teachers, visitors, leaders and other groups of the brand trend analysis. Through H3C Intelligent terminal recognition technology, can use the fingerprint level of terminal identification analysis of the current access to the wireless network terminal model, combined with H3C refinement management solution can be user population, location, time for in-depth statistics, the use of large data analysis follow-up can be based on the results of user consumption capacity, User brand preferences analysis , combined with the school's top business to provide users with more targeted services and so on.

Wireless Location

Wireless Location

With the campus wireless network and the application of mobile internet increasingly rich, more and more schools in order to meet users anytime and anywhere to use wireless network needs, the original office building and other small areas of coverage, extended to the canteen, dormitories, squares, halls and other large range of coverage, and wireless network construction more mature, Users are connected to the wireless network all the time. This also provides data support for wireless location analysis. In addition, we know that the advantage of wireless networks is that users out of the traditional wired network can use the network anytime, anywhere, and this mobile characteristics determine the coverage density before the construction of a simple estimate, the later use of the coverage effect, the subsequent use of population density is higher, whether and time related. In combination with large data technology, it can be used to calculate the user density of a certain time period, and to analyze whether the current wireless network needs to be optimized with the actual situation of bandwidth and traffic. The traditional positioning method has poor positioning accuracy and needs to be sampled in advance, which results in the application of wireless location in campus. H3C Innovative use of "Cupid" positioning algorithm combined with x-share positioning can be positioning accuracy of 2~3 meters, through the upper positioning engine can be connected to the school's business system, to provide large data analysis, the future will be widely used in schools.

Teaching

Now students learn and wireless network is closely related, through the wireless VOD video learning, System selection courses, ipad schoolbags, online interactive teaching, view school bus track, campus navigation, according to the statistics students more than 60% of the time in the use of wireless networks, of course, but also in the production of massive data, How to use these data to provide better service to students? We can use the course information to carry on the hot course and the free classroom analysis. such as: Li Ming is xx university students, evening to go to teaching upstairs self-study, the traditional way Li Ming is a classroom to find, to see which classroom people relatively few, better position. However, it is often better to go to the library or back to the dormitory than to find a vacant classroom for a long time. Or just sit down and read a book. Because there are classes, community occupancy and other reasons and have to look again, and the use of large data technology can be in the classroom density of the crowd, classroom leisure, students class classroom timetable information analysis, The school can analyze the free situation of each classroom by system to make the reasonable allocation of classroom, and can combine the timetable of the terminal to carry on the course information push and so on. Students can also use wireless terminals such as mobile phones, the ipad is very intuitive in the system to see how many people currently in the study room, so as to choose the right classroom for self-study, and in passing each study room will receive the current self-study room of the course information to arrange their own learning time. In addition, the use of large data technology to improve students ' academic performance is also a very important goal, students usually learn in life there are many information is often ignored by us, and through large data technology can be these important information analysis, such as classroom attendance, the hottest courses, the most popular classrooms and so on.

Life

For the "Big Data" in school life, there are already many colleges and universities in China to take the lead in the application, such as ECNU's "food warning" system, according to the students ' catering consumption statistics, if less than 60% of the students per meal consumption, these students will enter the list of further verification, After the accurate analysis of the study will be concerned about care. A student has received such a message as a result of a decrease in eating: "Students, found that you have less food consumption last month, do not know whether there is financial difficulties." Even some junior senior students because of the meal to buy a postgraduate examination information and do not know that the school also has a book fee subsidy, then the early warning system can also be reflected. Also embodies the humanistic care of the school. And the wireless campus in fact, the life of the "big Data" also has a wide range of applications. such as: Through the user's mobile trajectory, time, user type, wireless thermal map technology and other information analysis, students every day in the teaching building which floor which classroom of the stay time, combined with the curriculum information, reminding the students to stay in the classroom for a long time to pay attention to work, vice versa pay attention to homework The staff flow of the canteen at various windows as a popular basis for dishes, at the same time in combination with the information push the way to push the daily specials; which library of libraries, which book is the most popular, and when the most popular books are automatically pushed through a bookshelf; Analyze the user's long-term mobile trajectory, such as matching the classroom-dormitory-canteen three and senior students, and then do accurate judgment statistics for the postgraduate examination preparation students, for postgraduate school related information such as preparation guide, remedial class related information recommended.

The above introduction is only the campus wireless large data application of the iceberg, and the list of scenes is the school most often encountered several scenarios, wireless large data in the campus application there are many. Today is a mobile internet era is also a huge number of data outbreaks in the era, how wireless, large data technology to combine for students, teachers teaching, life, entertainment to create a better environment and experience, is the direction of everyone has been working.
