Audiovisual System Upgrade in Classrooms and Conference Rooms
Transition of Multi-Display Systems to LED Displays and Conversion of PC Classrooms to BYOD Environments
Background
Since its establishment in 1907, Tokyo Denki University has produced many outstanding professionals under its educational motto of “In the Technology Breathes its Creator.”
The Hatoyama Campus was opened in Hatoyama, Saitama Prefecture in 1977, followed by the Tokyo Senju Campus in 2012 as part of the university’s 100th anniversary commemorative project.
To further enhance its educational and technological infrastructure, the university has upgraded the audiovisual systems at both the Tokyo Senju Campus and the Saitama Hatoyama Campus.
