How Cell Phone Jammers Work
Mobile phone jammer is a device used to block signals between cell phones and towers to block Mobile handy mobile phone users to make and receive.
Why would you want one? So we all met someone who interferes in the cinema, restaurant or continue to bark where distance between the consideration of others.
While most of us just complain in a low voice, some take matters into their own hands and buy a laptop Yapper zapperThe jammer works by sending a signal on the same radio frequency used by mobile phone. Signals from cell phone jammer and collided just cancel out.
Now, on the phone informs you that the service or no network signal. Mobile phones are two-way devices, so as to use two separate frequencies, one speaks and another listens at the same time.
Some jammers block only one of the frequencies used by mobile phones that have the effect of blocking both. The phone is led to believe that there is no service because it can not receive one of the frequencies.
Less complex devices block only one group of frequencies, but a sophisticated jammers can block several types of networks at the same time head off dual-mode phones or tri-mode automatically to different types of networks to find a signal of openness. Some high-end devices block all frequencies at once, and others can be tuned to specific frequencies.
Jam Mobile, all you need is a device that sends the right frequencies. Although different cellular systems process signals differently, all mobile phone networks use radio signals can be interrupted. Using the GSM digital cellular and PCS-based systems, operating at 900 MHz and 1800 MHz frequency in Europe and Asia, and 1900 MHz (sometimes referred to as 1.9 GHz) in the United States.
Jammers can transmit on any frequency and are effective against the AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. The old analog phones phones and digital cameras today are so susceptible to interference from cell phones jamming.The device, often disguised as a normal mobile phone blocking cell phone signals within a range of up to 30 feet. Sometimes refereed to as a cell phone blocker, which were originally developed to enable police officers to interrupt communications by criminals.
Mobile Phone Jammer is suitable for meeting rooms, conference rooms, museums, galleries, theaters, concert halls, churches, temples, restaurants, classrooms, training, factories, banks, trains, buses, etc., or if you want to avoid the disclosure secret information in the face, otherwise you will need peace and quiet.
