cell phone jammerwill not interfere with other electronic devices

Each cell phone model and produce vendors, as described above may not apply to works for some cell phones, but generally the work process should be the same. Now the cell phone has gradually out of the identity of the simple communication tools, and gradually transformed into a multimedia and information terminal equipment, and daily activities such as communication, entertainment, financial, through the cell phone to. When we see a novel and has a high-performance, bright design cell phone, whether you have such a curiosity, this cell phone in the end is how the design and manufactured in every time? The signal emission performance and distribution of omnidirectional antenna of cell phone jammer is described as follows.
So today we try to use a technical objective perspective, a brief description of the relationship between the structure of the cell phone design department and departments, and finally to show the various tests before the cell phone to be available by the manufacturer, so that we can better understand the cell phone more cherish your love machine You may in the future will not be easily replace it right. baseband processor: Call Processor CPU separated voice and data signals in parallel sent to the digital signal processor DSP, DSP, voice decoding to interwoven work, the voice encoder PCM voice number, mode conversion, the final voice signal amplification by the evacuation receiver to send, then the process is the opposite. Multiple cell phone site testing is will be adopted for cell phone jammer.
Control parts: the Call Processor multi-analog converter chip serial digital data sent by the signal separation control data and language data signals, control data signals together by the call processor, the CPU and associated modules, the corresponding logic control timing control signals to coordinate the closing of the machine, send the information processing and peripheral control driver that works Call Processor CPU module to complete the channel coding and decoding. SIM card reader port with cell phones and GSM system, each When powered up, the cell phone must be the SIM card for data exchange can be measured on the SIM card holder data signals with an oscilloscope, no card, the signal will not be issued. The small-power mobile phone jammer needs to be installed with directional antenna in some situations.
Deck to provide the communication interface of the cell phone and SIM card in the cell phone, through the spring on the deck with the SIM card contact. ID: industrial design, including the cell phone's appearance, texture, feel, colors, the realization of the main interface and color design. MD: namely, structural design, the first shell of the cell phone, after the shell, the rotation of the cell phone camera lens position, fixed, the battery connection and the thickness of the cell phones belong to the structural design. HW: hardware design, the main content for the design of circuit and antenna. SW: that is, software design, due to the proliferation of computers, software is more easier, SW design should give full consideration to the operability of the interface, whether humanity, whether aesthetic factors. Compared with limitation of testing software by the cell phone and conversion after being tested by professional instruments, it is the easiest way to master for cell phone jammer.
PM: that is, project management, coordination and management of specific projects and planning. SOURCING (Ministry of Resource Development): new materials, new cell phone components, test equipment, etc. are SOURCING duties. QA: Quality Supervision, whose role is to bear the entire process of quality assurance work, supervise the development process in line with the scheduled process, to ensure the manufacturability of the project. Automated test software for a 1000 telecell phone call on the cell phone, check whether the cell phone fails if Chu Xiang is a problem, the software need to be rewritten. It is better that there is 3G cell phone of three different systems for testing of cell phone jammer including China Mobile TD-SCDMA, China Unicom CDMA 2000 and China Telecom WCDMA).
