Popularity and Challenges of Smartphones
The penetration rate of smartphones in Cambodia has reached more than 117%, and almost every student has a mobile phone. This popularity has brought convenience, but it has also caused many problems. First, smartphones are easy to distract students. In class, students frequently use their mobile phones to browse social media, watch videos or play games, which seriously affects their learning efficiency and class participation.GPS jammer

In addition, excessive use of smartphones may also affect students' social skills and mental health. Many students are addicted to the virtual world and neglect to interact with classmates and teachers, resulting in the degradation of social skills. Long-term use of smartphones may also lead to psychological problems such as anxiety and depression, affecting students' physical and mental health.

Mobile Phone Ban in Cambodian Schools
In order to cope with the negative impact of smartphones, many schools in Cambodia have begun to implement regulations prohibiting students from using mobile phones in the classroom. For example, schools such as Hun Sen Krong-Tep Nimit Pailin Middle School, Hun Sen Pochentong Middle School, Bun Rany Hun Sen Prey-Pon Middle School and Ta Ork High School have all taken similar measures. The mobile phone bans in these schools have been widely supported by parents, many of whom believe that this rule will help improve students' academic performance and attention.

Hun Sen Pochentong Middle School Principal Ong Mali said that since the implementation of the mobile phone ban, students have made significant progress in learning discipline and time utilization. Mobile phones of students who violate the rules will be confiscated, and the school will notify parents or guardians to go to the school office to pick them up. The implementation of the mobile phone ban has prevented students from playing games or browsing useless information on their mobile phones at any time, and they can concentrate on their studies.

Research supports the effectiveness of mobile phone bans
A research report from the London School of Economics supports this move by Cambodian schools. The study found that in schools where mobile phones are banned, students tend to get better test scores, especially for students with poor academic performance, the improvement brought by the ban is more significant. The study believes that restricting mobile phone use can be a low-cost policy to reduce educational inequality.

You Bentong, principal of Bun Rany Hun Sen Prey-Pon Secondary School in Prey Veng Province, also said that since the implementation of the smartphone ban, students' behavior has changed significantly. He observed that students pay more attention to learning and the proportion of students passing exams has increased significantly. This evidence shows that the mobile phone ban has a significant effect in improving the quality of education.

Application of mobile phone jammers
In order to effectively implement the mobile phone ban, schools can consider using mobile phone jammers. Mobile phone jammers block communications by emitting electromagnetic waves in a specific frequency band to interfere with mobile phone signal reception. This device can help schools effectively manage students' mobile phone use and ensure classroom concentration and order.

Advantages of mobile phone jammers
Improve classroom attention: By blocking mobile phone signals, students cannot use mobile phones in class, which helps them concentrate, participate in classroom activities, and improve learning effects.

Reduce academic fraud: During exams, mobile phone jammers can prevent students from cheating through mobile phones and ensure the fairness and impartiality of exams.

Promote student social interaction: By reducing the use of mobile phones, students have more opportunities for face-to-face communication and interaction, which helps to cultivate their social skills and teamwork spirit.

Protect students' privacy: Mobile phone blockers can prevent students from spreading bad information through mobile phones on campus and protect students' privacy and safety.

Precautions for implementing mobile phone blocking measures
Although mobile phone blockers have many advantages, schools need to pay attention to some issues during implementation. First, schools should clearly formulate relevant regulations and policies to ensure that students and parents understand the purpose and necessity of mobile phone blocking. Second, schools should ensure that students and parents can contact the school in time in an emergency. Finally, schools should combine other educational measures, such as time management and learning habit cultivation, to comprehensively improve students' learning effects.

Conclusion
The regulations of Cambodian schools prohibiting students from using mobile phones in the classroom have been widely supported by parents, showing the effectiveness of this measure in improving the quality of education and students' attention. As an effective management tool, mobile phone blockers can help schools better implement the mobile phone ban and ensure the concentration and order of the classroom. However, technology is only an auxiliary means. The key lies in how to use technology reasonably to promote the development of education. Through scientific management and effective measures, we can find a balance between technology and education and promote the progress of education.
