Spokane, Washington-A school in Spokane, Washington, was frustrated by the continued interference with cell phone text messages and calls. It has invested in a device that prevents the phone from working.
Spokane Mountain purchased the mobile phone blocker online for less than $ 100, and just completed a three-day trial period to frustrate students writing in class.
Director John Hook said: "We just think this is something we want to evaluate."
The Mead School District and the FCC work together to determine whether the portable jammer device is legal before use. The jammer is turned on during class hours and turned off during transit time and lunch break. In this way, students can concentrate on listening to the class during class and relax with a mobile phone after class.
Hawke said: "We believe that during school, sometimes parents need to contact students, and students must contact family members, doctors, etc."
School is the best place to study: in school, students should abide by the school ’s regulations, do not use mobile phones during school, and maintain good teaching habits. Using cell phone jammers is not a good way to solve the problem, this is only a mandatory measure, it will cause many people to resist.
