Cell phone Jammers

Many churches, schools, government, and even some entertainment venues have installed cell phone jammers in their buildings in other countries. The Indian government started installing them in their buildings when politicians refused to shut off their phones. Many churches decided to install them as well because cell phones would interrupt mass especially at weddings. Some universities also installed these cell phone jammers as a way of preventing students from using their cell phones to cheat by text messaging or taking pictures of the tests. The cell phone jammers cost approximately $2,000 a piece and emit a low level frequency in a hundred foot radius. The jammers make cell phones have a no service or signal not available on their cell phones. As of right now there are laws against using these in the United States and most western counties, but it is very possible for those laws to be overturned one day.
