How would you react if someone used a cell phone signal blocker on you? Recently, a high school in Washington purchased a cell phone signal blocker for less to make a test for three days during class periods. The phone jammer was then turned off during breaks and lunchtime. Why do the leaders of the school tried to install a cell phone jamming blocker in the school? They found that their students put too much time on their phones, even in the school time. During the class, the students are texting messages all the time,
which has already quickly gained popularity in high schools nationwide. As a result, it is becoming more and more of a class distraction and educators are becoming increasingly frustrated. After repeatedly asking students to shut off their cell phones in the class, the school leader decided to try a different route. So, they installed a cell phone signal blocker for a test. Whether a phone signal jamming blocker is capable enough of blocking cell phones? Cell phone signal blocker is a kind of device used to prevent mobile devices from receiving signals from base stations. Originally designed for law enforcement and military use, phone signal jamming blockers are generally applied for the security purpose that they can prevent the terrorist attacks. How does a cell phone jammer work? In all, they use antennas to send radio waves in the same frequencies that cell phones use. This causes enough interference to make cell phones within the shielding range of a phone signal jammer. The newly designed phone signal jamming devices are palm-sized and often disguised as a pack of cigarettes. Why cell phone jammers enjoy wide popularity in the modern society? Think about it in this way. You’re sitting in a cafe enjoying the afternoon tea with your best friends. Suddenly, a stranger’s voice pitches higher and floats across the room. He is talking out loud with his phones, which is noisy enough to spoil your peaceful leisure time. What will you do? Such matters often happen in many other places, for example churches, libraries, restaurants, cinemas, as well as various public places. Assume, someone’s phone rings when you are praying earnestly in the church, or someone next to you talk out loud with his cell phone when you are enjoying a Hollywood blockbuster, or phones rings now and then when you are carrying a commercial negotiation with a VIP customer, what will you do? Will you turn on a cell phone signal jammer? Maybe, you can think in another way. How would you react if someone used a cell phone jammer on you while you are having a phone call with your boy friend or girl friend? Do you still think using a cell phone jammer could be beneficial, or that they should always be illegal?
