In the GSM mobile phone jammer

Effect of cell phone jammer should be maintained
19 State Planning Commission approved the CDMA mobile phone manufacturers. Which in addition to Motorola, the remaining 18 companies all of the domestic mobile phone manufacturers, but because of the domestic mobile phone enterprises lack the core technologies, can only adopt a "market for technology" in Sino-foreign cooperative approach to achieve their own in the huge market The steady development. Almost every Chinese mobile phone maker behind Japan and South Korea have a cell phone jammer manufacturer's shadow. Kejian's in South Korea's Samsung is the most typical example. Samsung for China's CDMA mobile phone market all of this joint venture plant, not imported. The cell phone andcell phone jammer are also widely used in the industrial or agricultural production.
In addition, the wave of LG, Kyocera Zhenhua Guizhou, Tianjin Sanyo, etc., most of the obtained licenses for the production of domestic CDMA handset joint venture companies have chosen the form of supply to the market. In order to meet the current demand characteristics of the domestic mobile phone market in 2007, China's foreign mobile phone brands every two days on the launch of a new model, with higher technology constantly update function to launch the product, reflects the "new" fashion. Domestic mobile phone is not far behind, with a unique sensitivity to the market, they have limited funds into local innovation, to design a truly meet the spending habits of the Chinese mobile phone products. With in-band external camera, MMS, digital camera and other selling points, camera phones welcomed by consumers, quickly become a hot market. However, the cell phone will generate some problems which can not be ignored so thatcell phone jammerhas to be used.
Although the domestic mobile phone enterprises in the domestic mobile phone market has had a good performance, but with a large number of foreign mobile phone companies compared to domestic mobile phone enterprises in many respects, there is a big gap.

R & D progress, overall still a disadvantage. China's mobile phone production enterprises R & D progress in the short term strength is no doubt, but the technology gap that still could not escape the domestic mobile phone the kinds of situation. Of the 3G standard, has studied abroad for six years to eight years, and our study only two or three 3G standards. The cell phone facilitates people’s life butcell phone jammer is still needed.
In the GSM mobile phone jammer, although the domestic mobile phone business from the "OEM" production into the core technology of production level, in technology development and world-class distance is shortened, but the overall technological level of domestic mobile phone enterprises are still far behind the foreign mobile phone companies , almost all of the core technology lies in the hands of foreigners. Domestic mobile phone manufacturers have not fully mastered the manufacturing of mobile phone baseband chip, RF core, the core technology.
