Introducing SMa-818B and SMa-818B5 Signal Blockers
As the end of the semester approaches, schools are entering the final exam preparation phase. Some teachers and parents are concerned about the impact of excessive smartphone usage on students’ academic performance. It is widely known that children’s mobile data usage comes from two sources: the various plans and data packages provided by parents, and the Wi-Fi signals available in their surroundings. How can we effectively block Wi-Fi and mobile signals? The solution is simple – signal blockers, specifically the SMa-818B and SMa-818B5 models, which are highly recommended due to their low power consumption and effectiveness in blocking both Wi-Fi and mobile signals.
Children’s mobile data usage primarily relies on two sources: the plans and data packages provided by parents, and the Wi-Fi signals available in their surroundings. By using signal blockers such as the SMa-818B or SMa-818B5, which are single-unit devices that can be easily powered on, both Wi-Fi and mobile signals can be blocked simultaneously. When the signal blocker is active, the signal bars on children’s phones will display zero, preventing them from accessing the internet, browsing web pages, watching videos, or playing online games.
The SMa-818B5 signal blocker is specifically designed to block and interfere with Wi-Fi signals in two frequency bands: 2.4GHz and 5.8GHz. Therefore, teachers and parents do not need to worry about whether the Wi-Fi router or amplifier being used is dual-band. Additionally, the signal blocker is capable of blocking mobile signals across all frequency bands, including 2G, 3G, 4G, and 5G. This ensures that regardless of the type of mobile network technology being used by children, their signals will be completely blocked.
In conclusion, the SMa-818B and SMa-818B5 signal blockers provide an effective solution to prevent students from becoming addicted to mobile phones. By blocking both Wi-Fi and mobile signals, these devices help create an environment conducive to focused studying and reduce distractions caused by excessive smartphone usage. Teachers and parents can now rest assured that their efforts to promote academic success will not be hindered by the negative effects of smartphone addiction.
