Why do children need to stay away from their phones

In addition to the school order framework, Mr. Brown stressed that the cell phone jammer ban is also a “public health message that is good for the family” and is good for children. He warned parents not to let their children touch screens for long periods of time, especially before the age of seven. That was the promise of Mr Macron’s presidential campaign.

But the implementation of the measure is expected to be complex. The education law has stipulated that mobile phones should not be used in primary and middle school classes. The teachers’ unions are particularly sceptical. On the one hand, many parents believe that children are not connected with their mobile phones. On the other hand, students’ schoolbags are likely to become new jobs for school employees, which can easily lead to conflict.

So what are these devices for? The reporter found xu hong, deputy director of the school’s modern education technology center. Xu Hong told students to these electronic equipment after the purpose of speculation and opinions, some regret told reporters: “may be the time is hasty, haven’t come yet and the students in our school specifically explains the purpose of these electronic devices, the electronic equipment is used for construction of standardized examination room, do not use at ordinary times, more is not used to monitor student.”

Special agencies also need to shut down cell phone signals

The Federal Bureau of Prisons (BOP), in collaboration with the National Telecommunications and Information Administration (NTIA) and the Federal Communications Commission, conducted a test of micro-jamming technology at the Federal Correctional Institution at Cumberland, Maryland. The test was conducted to determine if micro-4G jammer could prevent wireless communication by an inmate using a contraband device at the individual cell housing unit level.

Next week, the department will begin testing a “micro-jamming” system to evaluate whether such technology can be used to halt inmates’ calls without disrupting services in the surrounding area, including those used by first responders.

Stopping drones is difficult. “Technological solutions to detect and disrupt drones are in their infancy,” Rosenstein said, adding that the Justice Department supports regulatory changes that would make it easier to deploy interdiction technology and cellphone jamming.

According to a statement, the Federal Bureau of Prisons tested the “micro-jamming” technology at the Federal Correctional Institution in Cumberland. Officials wanted to test whether the system could jam a device in a specific cell.
