Are You Annoyed by Abuse of Cell Phones?

What can a cell phone signal blocker do?

Since so many people have been annoyed and inconvenienced by the ubiquitous abuse of cell phones, new innovation would lead to simple solutions, and in many other countries, the solution is the portable cell phone signal blocker . The cell phone signal blocker sends out a blanket of noise in the same frequency range as the cell phone, and by raising the noise floor, makes it impossible for the phone to stay connected. The cell phone user doesn't know the cause of the interruption, in most cases, and just puts off the conversation until later.

Where and why do people use a cell phone signal blocker?

In various countries, museums and restaurants use full-time cell phone signal blocker, because, as many people around just won't cooperate and turn their phones off. Jamming is only permitted in countries where the overall benefit to society is more important than some individual's hurt feelings. So, the use of a cell phone signal blocker may be illegal, yet there are those who are so irritated by mobile phone addicts that they don't mind taking the risk of operating outside the law for a few seconds at a time in order to cut off someone else's conversation, especially when that conversation seems to go on and on, and seems to get louder and more frivolous with every passing minute. The science of jamming a cell phone are actually quite simple. Mobile phones operate by sending signals along a range of the electromagnetic spectrum reserved for their use. All a cell phone signal blocker needs to do is broadcast a signal on those same frequencies, and it will interfere with any devices trying to transmit in that range. The phone's screen will simply indicate that no signal is available. A pair of US inventors are bringing to market a computerized car key that prevents people from chatting on mobile telephones or sending text messages while driving. This Key2SafeDriving adds to a trend of using technology to thwart speeding, drunken driving, and other risky behavior proven to ramp-up the odds of crashing.
