Chieru Corporation (Headquarters: Shinagawa-ku, Tokyo; President: Mutsumi Kawai), which supports ICT utilization for school education, announces that it will add an edge cache function to 'Tbridge® 300', the entry model of its 'Tbridge®' series of wireless communication visualization and stabilization solutions, starting in April 2026. This will make the edge cache function available on all models we offer.
**■ Background: Acceleration of Digital Textbooks Becoming Official Textbooks**
On April 7, 2026, the government approved a cabinet decision on a bill to amend the School Education Act, positioning "digital textbooks" as official textbooks. Digital textbooks, which have been treated as "special teaching materials that can replace paper textbooks," are expected to be officially used as textbooks in schools nationwide as early as fiscal year 2030, after passing the textbook screening in fiscal year 2028 if the bill is enacted.
With the spread of digital textbooks, school networks are required more than ever to handle simultaneous access from one device per student and to provide a stable communication environment. Particularly in small schools with fewer students, products designed for large-scale use often do not offer good cost-performance, creating a hurdle for implementation. Chieru decided to add the edge cache function to 'Tbridge® 300' to address these challenges.
**■ What is Tbridge®?**
'Tbridge®' is a wireless communication visualization and stabilization solution that has been implemented in over 2,400 schools (as of March 2026). It visualizes the operational status and communication quality of access points in real-time in Wi-Fi environments at schools and companies, enhancing communication stability.
In school settings where one device per student has been provided under the GIGA School Program, network congestion and delays have become a serious issue as many devices communicate simultaneously during classes. 'Tbridge®' ensures stable communication even in such environments and optimizes the communication environment.
We currently offer three models: 'Tbridge® 300' (for small schools), 'Tbridge® 500' (for medium-sized schools), and 'Tbridge® 1000' (for large schools), allowing customers to choose the optimal model according to the school size and usage environment.
**■ Effects of the Edge Cache Function**
The "edge cache function" is effective in environments where the same content is often used within a classroom, such as digital textbook content and OS update data. By temporarily storing content data within Tbridge®, it significantly reduces the load on the internet connection.
