Damaging the phone is the same as any other type of radio interference. The cell phone works by communicating with its service network through a cell tower or base station. A cell tower divides a city into a small area or neighborhood. When the mobile phone user enters the street, the signal is sent from the tower to the tower.
The jammer device, which is fired at the same radio frequency as a cellular phone, interferes with the communication between the phone and the cell phone base in the tower.
The interference device causes two signals to collide and eliminate by transmitting signals at the same frequency and high enough power to signal the same frequency as the cell phone signal. The phone is designed to increase power, and if they encounter low levels of interference, the scrambler signal must recognize and match the increased power of the phone.
The phones are full-duplex, which means they use two different frequencies, one for calls and one for listening at the same time. Some gps jammer can only block one of the frequencies used by the phone, which can hinder the effect of both. The phone was tricked into believing there was no service because it only received one frequency.
Less sophisticated equipment can prevent a set of frequency, and complex jammer can prevent many types of network at the same time, to prevent the dual-mode or three mode mobile phone automatically switch between the different types of network to find the signal. Some high-end devices block all frequencies at once, while others tune to a particular frequency.
To stop the phone, you need a device that broadcasts at the right frequency. Although cellular systems have different process signals, all cellular networks use radio signals that can be interrupted. GSM, which is used for digital cellular and PCS systems, works in the 900 MHz and 1800 MHz bands in Europe and Asia, as well as in the United States in 1900 MHz (sometimes called 1.9ghz) bands. GPS scrambler can be broadcast on a frequency, which is valid for AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN and Nextel systems. Older analog phones and today’s digital devices are also vulnerable.
Recently, I made a survey about children should use a mobile phone, according to the survey, sixty percent of parents think can give children the use of mobile phones, it is very convenient to contact their parents and friends, what an emergency contact to loved ones can also be the first time. 10% of parents said their children use mobile phone doesn’t matter, because they came home, every day have a telephone in the home, parents also have a cell phone, they can use at home, at school, there is no need to use. Thirty percent of parents believe their children should not use their mobile phones. Although the mobile phone provides them with great convenience, it also poses a threat to them. And today’s Internet network forms, such as all kinds of fraud and pornography, child’s self-control is not as strong as we are, they are vulnerable to temptation, especially when they will be addicted to the game, but ignored the study. What do you think about this problem?cell phone jammer can be used to solve the problem of mobile phone use.
