Cell Phone Jammers are centrally installed on the top floor

Cell Phone Jammers are centrally installed on the top floor. 
Can be seen as pocket-sized mobile computer. It has a CPU, memory (flash, RAM), input and output devices (keyboard, screen, USB, serial). It also has a more important I / O channels, and that is the air interface. Phone over the air interface protocol (such as GSM, CDMA, PHS, etc.) and base station communications, both voice, you can transfer data. Phones are generally not independent of the CPU chip, but a baseband chip unit, known as the CPU core. Phone baseband chip is the core, which includes not only the CPU core, DSP core of these more generic unit also includes communication protocol processing unit. Communication protocol processing unit and mobile air interface protocol software with the completion of the requirements of communications. The signal dead zone should be checked if turning on all Cell Phone Jammers .
With chip technology continues to evolve, more and more peripheral circuits can be integrated into the baseband processor chip, such as BAP, the analog baseband processor. This phone was probably getting smaller and smaller, lower cost more to do. Many mobile phones have only one CPU, baseband chip is the CPU core. He walked on the CPU both in the communication protocol, but also to implement the user interface (UI). DSP will share some of the calculated amount of heavy work, such as voice codecs, security layer of various algorithms. In a market driven by the continuous development of mobile phone functions. Camera, MP3, Bluetooth hardware can rely on these features, the pressure on the CPU is not great, but the java virtual machine, embedded browser and other applications will have high CPU resources requirements. Single-CPU priority is to complete the communication protocol. Communication protocol software with precise timing requirements, if the CPU but also on many applications, then it is inevitably difficult. So dual-CPU mobile phone came into being. The distance of installation position of Cell Phone Jammers should be adjusted.
As the name suggests, is to have two dual-CPU mobile phone CPU, a CPU to do the communication protocol, and the other CPU is responsible for UI, java virtual machine, embedded browser applications. Can be done in a two CPU chips inside, can also be separated. The market reality is that many mobile phone design company (Design House) no baseband chip development capabilities, they bought the mobile phone module of foreign companies, on the outside plus a CPU. Communication protocol module to run, plus the CPU to run their own UI and application software, both through the serial port communication. Of course, there are many foreign purchasing program Design House's board-level development program, make their own PCB, the software is to change to change the main UI and peripheral drivers. Basically, smart phones on the market all those dual-CPU solution, what is Windows The quantity of Cell Phone Jammers can be increased or reduced according to the reality.
