Success Case_ Fuzhou Wenbo Middle School Uses Digital Signaling Precise Shielding to Protect Teenagers’ Physical and Mental Health

Success Case: Fuzhou Wenbo Middle School Uses Digital Signaling Precise Shielding to Protect Teenagers’ Physical and Mental Health
When education meets technology, every protection is precise and powerful. We are proud to share the successful practice of Fuzhou Wenbo Middle School — by deploying the mobile phone signal digital signaling precise shielding system, the school has achieved remarkable results in preventing students from indulging in electronic products and protecting the physical and mental health of teenagers.

Project Background: Educational Pain Points and Innovative Choices
As the only private middle school in Fuzhou rated as a Level 2 Standard High School in Fujian Province, Fuzhou Wenbo Middle School has always taken "laying the foundation for students’ lifelong development" as its mission and actively strived to become a Level 1 Standard High School in the province. Faced with the problem of students’ addiction caused by the popularization of smartphones, the school management rejected the traditional "one-size-fits-all" shielding solution and chose digital signaling precise shielding technology, aiming to achieve:
• ✅ Effectively block mobile phone network interference in classrooms and dormitories to improve learning concentration
• ✅ Protect students’ physical and mental health and reduce dependence on electronic products
• ✅ Adopt a green, environmentally friendly and low-radiation solution that meets campus health standards
• ✅ Do not affect emergency communications and the normal use of teaching equipment

Technical Highlights: Precise Control, Green Protection
Different from the traditional "indiscriminate noise suppression" shielding devices, this system adopts protocol layer intelligent interference technology, achieving three major breakthroughs:
Technical Dimension
Traditional Shielding Solution
Digital Signaling Precise Shielding
Interference Method
High-power full-band suppression
Precise protocol layer commands (reject access/release connection)
Radiation Level
High (continuous high-power output)
Low (only 1/5 of the power of traditional equipment)
Energy Consumption
High (continuous full load)
Green and Environmentally Friendly (power consumption reduced by more than 50%)
Control Precision
Uncontrollable range, easy to interfere with the surrounding area
Precise coverage of target areas, no impact on emergency communications
Compliance
Prone to violations, interfering with legal communications
Compliant with communication protocol standards, selective shielding
The system adopts a three-step process of "listening-analyzing-interfering", actively establishing connections with mobile phones and issuing compliant commands to guide mobile phones to take the initiative to go offline, rather than violently suppressing signals. At the same time, it supports precise control by time period, area and operator, realizing humanized management of "shielding during class and opening after class".

Implementation Results: Multidimensional Improvement, Remarkable Achievements
Since the deployment of the system, Fuzhou Wenbo Middle School has achieved comprehensive improvement in educational quality:
1. Improved Learning Concentration: The violation rate of mobile phone use in class dropped from 37% to less than 0.5%, and teachers reported a 40% increase in classroom interaction.
2. Improved Students’ Physical and Mental Health: Data from the campus psychological counseling center shows that cases of anxiety caused by mobile phone dependence have decreased by 65%, and students’ average sleep quality has increased by 1.2 hours per night.
3. Improved Teaching Efficiency: The effective teaching time per class increased by 15-20 minutes. The 2025 high school entrance examination results improved significantly, with the admission rate to the top three key high schools (No.1 Middle School, No.3 Middle School, Affiliated High School of Fuzhou University) reaching 7%, and the admission rate to the top nine key high schools reaching 24.2%.
4. Surge in Parent Satisfaction: 98% of parents recognized the program, believing that the school has shown professional responsibility in protecting their children’s physical and mental health.
Educational Enlightenment: Empower Education with Technology, Guard the Future
The successful practice of Fuzhou Wenbo Middle School proves that the organic combination of educational management and technological innovation is an effective path to solve the problem of teenagers’ dependence on electronic products. This project not only provides a replicable "anti-addiction" solution for schools in Fuzhou, but also sets a "green, precise and humanized" benchmark for campus management for educational institutions across the country.
"Our goal is not to ‘ban mobile phones’, but to guide students to ‘use mobile phones rationally’. Digital signaling precise shielding technology allows us to cultivate students’ self-discipline and digital literacy while ensuring their healthy growth." — Zheng Baosheng, Principal of Fuzhou Wenbo Middle School
