Federal government wants drivers to stop using, looking, and typing on their handheld devices or cell phones. On the other, the government is against a simple solution to guaranteeing people stay off their phones while behind the wheel. At the heart of the opposition to jamming is a concern that it takes away a drivers freedom to call or contact others while they are driving. Actually, if you run your phone through your car, you’d still have that freedom. And since putting the cell phone jammer or some other jamming device in a car would be voluntary, those who still want to have access to their phone would not be impacted.
With the popularity of smart phones, now in public places unscrupulous use of mobile phone phenomenon can be seen everywhere. When you listen to light music, enjoy dinner, there will always be annoying ringing sounded. When you are in the cinema and the theater to enjoy the wonderful clips, always hear the voice of the phone camera. When you pray in the church, there will always be a ringing tone to break the tranquility.
Cellular access control is a technology born of necessity. Around 2006, Mississippi correctional authorities found they were fielding more citizen complaints of harassment from prisoners using cell phones. Efforts to block the contraband phones were increased, but were not completely successful. “There was talk of going to the FCC to allow signal jammer, but that never got off the ground,” said Smith.
Desktop Jammers usually can block all cellphone, can be a good guarantee of the surrounding quiet. At the same time, desktop jammers also have a large jamming range, jamming signal stability characteristics. For the user, this is a very good feature.
GSM jammers, also known as cellular jammers or mobile phone jammers, are designed to prevent cellular communication in designated areas. The cellular jammers emit RF jamming interference signals that attack the abilities of a mobile phone to receive service from a cellular network. That means that if a cell phone user is beginning to make a call or is already engaged in a call, cell phone jamming will overpower the carrier signal and terminate the call.
