The technology review of Cell Phone Jammers has been done

It is output of current of  Cell Phone Jammers .
Timer There are two types: First, the increment counter; two Reduction counter. When the timer overflows, the incremental calculator to generate an interrupt for standard bit; when the timer back to zero, decrement the counter generates an interrupt. Some timer also has the ability to automatically re-load, which makes the use of more flexible and convenient to use this function it is easy to generate a programmable clock timer. In addition, the timer can also be used as an event counter, when working in counter mode can specify the input of the input pulse, the counter to count operator. The clock system is a microcontroller system, the microcontroller step by step, according to certain rules, arranged in chronological time, is controlled by the clock system. The technology review of  Cell Phone Jammers  has been done.
It also has a more important I / O channel, that is, the air interface. Phone over the air interface protocol (such as GSM, CDMA, PHS, etc.) and base station communications, can transmit voice, you can also transfer data. The phone's CPU is not a separate chip, but a unit of the baseband processor chip, known as the CPU core. The baseband processor chip is at the core of the phone, it contains not only the CPU core, DSP core generic unit also includes the communication protocol processing unit. Communication protocol processing unit and a mobile phone protocol software to complete the air interface requirements of the communication function. As chip technology continues to evolve, more and more peripheral circuits can be integrated into the baseband processor chip. It shows the cause and effect relationship of  Cell Phone Jammers .  
And then the same with the infrared interface devices for information exchange; infrared interface eliminates the need for download or the costs incurred by the other exchange of information; due to the need to butt in order to transmit information, more security; infrared technology Disadvantages: short communication distance, communication can not move in case of obstacles breakdown in communications; infrared communications technology intended to replace the cable connection for wireless data transmission, single function, poor scalability. Characteristics of infrared technology. Infrared communication technology suitable for low-cost, cross-platform, peer-to-peer high-speed data connection, especially for embedded systems. The main application of infrared technology: devices interconnected information gateway. Device interconnection to be completed by the exchange of documents and information within the different devices.   As we all know, a core component of the GSM mobile phone logic system is the central processor, all it is called the CPU.
