How can one prevent children from accessing the internet on their mobile phones and control the duration of their usage?

Blocking children's mobile phone signals is a necessary step to protect their well-being. Since birth, children are constantly surrounded by electronic gadgets, which can negatively impact their growth and development. Hence, it is essential for us to take prompt action in order to safeguard children from the harmful effects of mobile phones.

In light of the new coronavirus pandemic, a considerable number of children have developed a habit of spending excessive time on mobile phones and playing online games on computers. Employing a signal jammer can aid children in gradually overcoming their internet addiction and gaining better control over their online activities. Additionally, adults can reduce their own mobile phone usage, allowing for increased engagement with their children and fostering a more harmonious family environment. Ultimately, this contributes to an improved family happiness index.

Method/Step 1: Restrict children's mobile phone access to the Internet in the router

By utilizing the security settings, all modern routers possess the capability to filter the MAC address of mobile phones, effectively preventing children's mobile devices from connecting to the Internet.By leveraging the router's capabilities, individuals with greater flexibility can effectively control children's internet usage by setting limitations on both access time and internet speed. This feature is commonly available in contemporary routers. Through the restriction of internet speed, children will only be able to utilize their mobile phones for informational purposes, while being unable to indulge in gaming activities.

Method/Step 2: Use a signal jammer

The advent of wireless networks has undeniably simplified Internet accessibility for individuals, yet the associated issues cannot be overlooked. It is not solely a question of network accessibility, but also a matter of ensuring network security.Signal jammers are employed in various locations to uphold a favorable network environment by deterring excessive network usage. This equipment has found extensive utilization across different countries and regions globally. Schools, prisons, libraries, reading rooms, and gas stations exemplify the typical settings where it is commonly deployed.

Under what circumstances does a mobile phone signal jammer have poor shielding effect?

1. In which situations does a cell phone jammer exhibit subpar shielding capabilities? In what specific environment can a mobile phone signal jammer be deployed to ensure optimal signal disruption?The efficacy of mobile phone signal jammers utilized in specific locations can be influenced by various factors such as the surrounding environment, installation position, distance, and the quantity of jammers employed.

Insufficient attention was given to data analysis, plane survey, shielding coverage plan, and other essential tasks during the early stage. Consequently, blind installation resulted in no impact and poor shielding effect. To avoid such issues, it is highly recommended to contact professional shielding customer service before installing the shielding device. They can offer expert advice and guidance. Furthermore, it is advisable to seek professional installation advice before purchasing a shield suitable for locations that require shielding.

WiFi is transmitted in many segments. Without testing or checking the professional frequency band technical parameters given by the manufacturer, it cannot be completely shielded. WiFi is divided into three segments (2.4G+5.2G+5.8G) with a bandwidth of several hundred megabits. This is why many customers say There is a WiFi signal shield, but when used on-site, you can still connect to WiFi and watch videos online normally.

2. The specified requirements for installation height are not met, and the installation position is deemed improper due to the presence of obstructions. Additionally, the use of partition walls leads to signal blockage.

3. The effectiveness of wifi jammer installed in specific locations may be compromised due to environmental factors. In particular, the presence of intelligent base stations within a distance of 200-500 meters can result in shielding failure. It is worth noting that these base stations typically operate at power levels exceeding 200 watts.When the base station encounters interference, it will automatically increase the transmission power, switch to a channel with a weaker interference signal, and have the ability to freely switch between channels. Mobile phone signal amplifiers are often found on the ceiling of locations where customers install mobile phone signal jammers.When the jammer and amplifier are employed concurrently, the effectiveness of the jammer's signal cancellation is compromised.

4. The incorrect selection of jammers can lead to their ineffectiveness. It is recommended to choose jammers based on the specific locations they will be used in. For example, prisons and detention centers should consider the completeness of channel shielding and the ability to operate continuously throughout the year. Medium-power mobile phone signal jammers are employed in prison buildings.Supplementary shielding and high-power directional shielding are achieved through the use of jammers in playgrounds and the release square, respectively, to ensure complete blocking of the prison signal. However, when prisons extensively rely on mobile phone signal jammers, it becomes arduous to manage and maintain them, resulting in escalated costs. To address this, the adoption of remote control software is being considered for efficient batch management.School examination rooms and conference rooms are generally open for a short period of several hours. They do not have high requirements on machine performance, but high requirements on shielding effect. For large areas, low power is recommended, or the power is insufficient and shielding cannot be performed. Directional shielding is required and external shielding is used. Problems such as insufficient full coverage lead to poor shielding effect and intermittent shielding effect when installing a mobile phone signal jammer. Choosing a low-power jammer in a large area or too high a power in a small area will result in improper purchase and poor shielding effect.
