The frequency channel of cell phone jammer is CDMA800

The phone uses the Symbian system is currently more common Nokia, Samsung, Siemens, SonyErrison (UIQ of the system). If I do not understand it correctly, Windows Mobile, formerly known as division of the more messy PocketPC, SmartPhone etc., are now unified into Windows Mobile. This series also has different versions, but the windows and the same is basically backward compatible, unlike Nokia's operating system, different versions were quite different. Domestic Cool, Meizu M8, etc. are used in Windows CE system, Windows CE system is relatively greater customization, but smaller market coverage.
Reporter: Is there absolutely none? Store staff: No, now how can there be no phone, no kind of machine. Explanation: The situation in the end forced to pay more serious? December 2009, reporters in the market to buy a 10 domestic mobile phone, and each test and found that all the charges built a variety of menu items. We clicked on the TSD 35 618 mobile phone charging menu, there is no reply to the confirmation of the operation, was charged 37.9 yuan information costs, related to the mobile value-added up to more than 10 suppliers. Intellectual source of information, including Hunan, Beijing Sohu Internet, Hainan public through computers, Beijing Gao Yang Sheng, Beijing to Xi Tong and so on. Hunan, Chi-information which will deduct a $ 15 fee. The frequency channel of cell phone jammer is CDMA800. Connectivity: general card + Adhesive hook linked with the front cover or only adhesive connection with the front cover. Keys according to the different materials can be divided into three types. Is completely RUBBER, the advantage of relatively low cost, can be directly open or soft silicone mold injection mold. Is completely PC, RUBBER + PC, Dome located in the following key, press down, it turns on the circuit below, indicates that the button is pressed. Divided into two types according to the different materials: Mylar dome and metal dome, the former is a polyester film, which is the foil. Mylar dome cheaper. Connection: glue stick directly on the PCB. Due to this kind of communication principle, cell phone jammer scans the forward channel from low frequency to high frequency
PCB board --- we generally use double-sided PCB board that is laminated on both sides of the middle of the distribution of copper, so that both sides of the PCB can be cloth parts, these parts including capacitors, resistors, IC, CONNECTOR, LCD, Shilding Case, Metal Dome. Divided into two kinds of exposed and hidden, in general, the former is better communication; standard parts, you can use. Connectivity: fixed on the PCB with metal shrapnel, the antenna can be directly stuck in between the two fragments.
