And the pletion of the campus work, to improve the quality of teaching and research, teaching and research to improve the conditions for schools to speed up the process of carrying out multimedia teaching and research, and teaching so that more people, more research results have important and farreaching Significance. The main local area work, including a variety of technical ideas, work design, work topology, cabling system, Intra / Inter applications, work security, work maintenance and so and universities and primary and secondary schools in preparation for building the campus work, and hopes that the campus work to improve the conditions for running schools, improve teaching, research and management. Campus work for schools is a major project must be carefully designed and construction work, so affordable, technologically advanced, open good strength and reasonable investment, domestic and international works and the Inter, longterm, stable operation Highperformance campus work.
