And the shielding range of this kind of cell phone jammer

And the shielding range of this

kind of cell phone jammer is about 2 to 50m
As a result of the MTK program of "black phones" is "domestic", so it was suggested that the concept of a "domestic brand", that is, to exclude the "black phones" mobile phone license system, but

then lower the threshold to repeal, some people began to be changed to say "black phones" "cottage", followed by such language "cottage brand" rise, or even days of the phrase market share also

occupy the first, and other brands are fully backward MTK platform. In this way, the endorsement of certain vested interests can not think of can be too high belittle someone else's term. Combined

with the Shenzhen local government to support the "cottage", the latter characterized as "primary innovative products, even more foggy. This kind of cell phone jammer can be used in the occasion in

I think would like to talk about domestic brand mobile phones must first find out what is domestic brand mobile phones, in my opinion, the state-owned enterprises or with the government to go

particularly close to listed companies, or low-key private capital to make a brand , has a high market share, should be seen as a domestic brand mobile phones. Domestic brand machines, divided into

five categories, first is the "Godfather", such as the CLP Group, a subsidiary of the large enterprises, Putian, ZTE, Datang, Huawei, and the like, including a particularly special relationship

with the operators such as UTStarcom classes. This class is a natural mobile phone manufacturer. Market performance, these companies rely mainly on the equipment to operators to bundle terminal

sales. For example, if the student is not allow to use the cell phone during class for it will influence teaching process and other students, cell phone jammer can be used to prevent the

phenomenon.And at the same time, the integrated circuit is the other remarkable characteristic of this kind of cell phone jammer .
I found that support for multiple operating platforms is the main strategy of the international big-name vendors, by virtue of their strong technical strength and the continuous strengthening of

the impact on the market. Smart phone chips predators Qualcomm claims that Qualcomm supports all smart phone operating systems, including Linux, WindowsMobile, Android, Symbian, and Brew mobile

platform. The spokesman said the terms of the chip maker Qualcomm pursues an open, multi-platform strategy to support the needs of device manufacturers choose different platforms.
