There are very few countries where mobile jammers are legally used
In the workplace, organizations are gradually learning that protecting sensitive proprietary and personal data may require them to use cell phone jammers in the office, thereby providing security by preventing data leakage or theft. The exponential growth of drones and their sometimes harmful purposes have persuaded security-conscious professionals to deploy cell phone jammer as standard operating procedures to protect people and places.
Mobile phone jammers are also often used around prisons and detention centers to prevent prisoners and detainees from communicating with the outside world without authorization and monitoring. Brazil, India, New Zealand and Sweden are countries that have been exempted or are considering exemption from using cell phone jammers near prisons, while in the United Kingdom, it has become legal since 2012.
However, some countries have allowed or proposed to expand the use of mobile phone jammers. For example, in India, it is stipulated that jammers can be used in schools, mosques and theaters, provided that it can be proved that the interference will not exceed its interference range. In a short period of time, cell phone jammers were also approved for use in theaters and concert venues, but the jammer was terminated in 2012.
So, what if you end up legally owning a cell phone jammer? You might consider booking your next flight to...Ukraine. Because the government has taken the initiative to prevent students from using mobile phones to cheat in exams, this is one of the few countries in the world where mobile jammers are legal.
