The advantages of 5G are high transmission rate, low latency, and high-density connections (a large number of devices are connected to the Internet at the same time in a small area). What impact do these three points have on the educational scenario? High Internet Speed ??As mentioned above, high Internet speed can support the implementation of VR education. In addition, it can also support the teaching scene of "group class". Secondly, the network delay of short-latency 5G can theoretically be controlled within 1 millisecond. The current delay of 4G is at least tens of hundreds of milliseconds. The teacher's picture is conveyed to the students, the students give feedback, and the picture or data is returned to the teacher. There is at least twice the delay in the process. In many cases, teachers continue teaching after seeing students’ feedback, which creates a very uncomfortable experience for students. After 5G matures, the short delay characteristics will greatly alleviate this problem.
To a large extent, high-density connections require the establishment of a large number of sensors and IoT devices in "smart campuses", "smart classrooms", and small areas. Current 4G and Wifi are both difficult to support. What's more, in a dual-teacher classroom in an actual working situation, there are dozens of students using answering machines in a class, and there are dozens of classrooms on a campus. How to support the stable connection of this answering machine is a big technical problem. challenge. With the arrival of 5G, this problem can be solved in a cheaper and more standardized way.
In the Internet information age, human society is about to start 5G high-speed wireless communication. What will follow will be the era of digital civilization of the Internet of Things, where everything is connected to the grid and everything is interconnected, or in the future. The basic characteristics of 5G are that network signals are available everywhere, traffic is large, and interactions are smooth. The basic characteristics of the Internet of Things are fully online, fully operational, smart terminals, and seamless experience, that is, everything is always online and interactive, and everything can display text and voice playback, video screen output, and even three-dimensionality. Obviously, many things will become the way of working, the way of life, the way of communication, the way of learning, etc.
For general education in primary and secondary schools, language classes are responsible for the education and learning of "literacy, reading, fame and writing". The mathematics class is responsible for the teaching and learning of "knowledge, calculations, rule operations, algebraic operations, equation interpretation, trigonometric principles and laws, geometric principles and laws". Of course, traditional educational activities in Chinese and mathematics are conducted during face-to-face lectures between teachers and students in the classroom. However, general education using 5G high-speed wireless communication needs to be accompanied by more and more multimedia forms, and multimedia will even become the mainstream of education methods. That's when tablets may be standard, or even free, for all students. Therefore, teaching materials, teaching aids, and educational courses must be changed, and teachers must also optimize and work efficiently. In other words, under 5G multimedia conditions, excellent teachers can teach more students, either at the same time or individually. Not just one to many, but one to many, to everyone.
