In the initial construction stage of the campus network or under the condition that the existing campus network is not complete, the deployment of the electronic class cards newly connected to the network needs to be connected to the nearby class cards in a WIFI hotspot mode. In an actual scene, the connection speed of the new class board and the network class board is influenced by physical positions of the new class board and the network class board, the layout of buildings such as classrooms and teaching buildings, in order to deal with the situation, the electronic class board is provided with the WIFI antenna capable of freely rotating in a large range, and on the basis of periodic analysis of the electronic class board on the signal intensity of surrounding WIFI hotspots, the WIFI antenna can be automatically rotated as required, so that a better signal intensity and connection speed can be obtained, the network time of the electronic class board is increased, and the usability and functionality of the new electronic class board are enhanced.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
