At the same time, the number of mobile phone users is the rapid growth of mobile phone development and popularity much faster than the fourth media ? the Internet, with China?s mobile phone penetration rate and total users rank first in the world. This is because the computers and networks, high barriers to entry, the technical and financial requirements are much higher than the mobile phone; the other hand, because the original function of the mobile phone voice calls, this feature is living in the lower level of consumption, Therefore, relative to the network more easily accepted by consumers. Difficulties and the problems facing the domestic mobile marketing. The core technology R & D and innovation to be a breakthrough. China?s mobile phone started relatively late. The jamming radius of this kind ofcell phone jammeris 0-70m.
China?s communication technology and electronic information technology is still far behind in the emerging mobile phone communications industry, mobile phones and foreign brands, which also makes our country in many of the communications technology have to rely on the purchase of developed countries to support production. R & D capabilities of the domestic mobile phone is too weak, while the proportion of investment in R & D cost is relatively small, it has no intention of making the profit margins of domestic mobile phone to be greatly compressed. Industry experts believe that the manufacturers take the OEM or own part of R & D have a great impact on the margin the level of. Kejian and the profit margins of the two brands have a clear gap, of course, with market volume size, but the main reason is that Kejian mainly rely on the OEM. The output power of this kind ofcell phone jammersystem is 60W.
TCL and waveguide as much as possible to increase the proportion of independent research and development, profit margins on many. In the electronic information and communication industry, the technology research and development costs have increased the intensity of inputs, technology R & D accounted for a large profit margins for electronic products, is one of the main profit growth point. In the high tech field, you want to survive in the fierce market competition, the only way is to always walk in front of other people?s, and all this have to rely on technology to boot. Nokia the world?s 55 000 employees, engaged in technology research and development staff of more than 17,000, reaching 31% for R & D of new products accounted for 9% of the total turnover costs. The power adapter used for cell phone jammer is AC220V-DC27V.
It also established 44 R & D centers in 12 countries around the world, including China,. Too little investment in technology development and research for the domestic mobile phone, a large number of manufacturers do not even have their own R & D institutions, take the OEM directly, by buying the technology of other manufacturers to operate, the question is no technical barrier conditions, This vendor also how long? Mobile phone R & D is divided into three parts, the most important part of the development of the core modules, experts estimate that it can account for more than 80% or even 90% of the cost of handsets, the domestic manufacturers in the purchase module, independent part of the design, while this part of the invested accounted for 10% of the cost, but also almost the only way to increase profits 10%. The switching power is used for cell phone jammer .
