CJAM Cell Phone Threat Scan Service (CJAM-CTS) blocks signals in areas where mobile service is not welcome. This is a HUGE help in schools and prisons (is that the same?) where cell phones are a big no-no.
CJAM CellAntenna blocks cell phone signals
Not only does it block the signal, but monitors the attempts. This gives the authorities a heads up on locating the illegal phones in the prisons, as well as the number they are trying to connect to in the outside world. With the growing problem of cell phones being smuggled into prisons, (See my blog California Bill to Impose Severe Fines for Smuggling Cell Phones into Prisons) finally there is a way to securely interrupt the process.
The company behind the service, CellAntenna Corporation, is not just a signal blocking company. It also provides a new stream of CAE-750 CT5 (Cat 5) dual band cellular and public safety repeaters designed for use during and after natural disasters, effectively providing assistance to communicate when other communication methods are down. The signal repeaters, also known as amplifiers, have a built in 8 hour battery, which helps immensely when not only are the land line phones are down, but also when there is no electricity due to the disaster.
Cell phones have been instrumental in assisting disaster relief in Haiti. When the earthquake hit Haiti in January this year, their wireless services were back up within 2 days (see my blog Cell Phones in Haiti are key to emergency services). So even though the signal blocking cell antenna may seem like another control issue for some of you, the company is just the big bad wolf.
With all technology there is a plus and minus. I think the signal blocking service will be extremely effective for use in preventing more crimes in prisons. With the ever growing problem with text messaging by teens in schools, this will provide a way to at least monitor it. But will the school authorities take it too far? Will there be a glut of confiscated phones in the Principal’s office? Will Big Brother extend his reach past the schools and prisons? What’s your take?
