Through these tests work, the main properties of the system to make a quantitative evaluation. Software testing methods are generally divided into black box testing and white box. The white box used in the local, mainly by developers, suitable for the development side, the side to test the software, contact the code. Black-box testing focus on the global concern is the functionality of the system is perfect, the system is stable. Before officially put into use, the software should be carried out two stages of black-box testing and white box. This chapter is the angle of the analog system users to test the system, the following main module test is expected to achieve the intended use. The normal use of the cell phone can be recovered immediately as long as the cell phone goes out of the blocking range or radius of cell phone jammer . 
Of course, we must admit that, objectively speaking, the domestic and foreign mobile phone also there is a natural gap between the domestic mobile phone already has a number of independent development capabilities, but the core software of the domestic mobile phone and mobile phone chip is largely dependent on imported . The lack of development capacity, the phone costs do not fall down, it has become the domestic mobile phone to give up low-end market, and embarked on one of the reasons of the relatively high profits in the high-end line. In fact, China has independently developed a mobile communication terminal products and the overall low level of self-development capacity is weak, irrational industrial structure, the level of core software and the key chip design and development needs to be improved, lagged behind the industrial development of the supporting components, supply shortages. It is within the blocking range and shielding frequency band of cell phone jammer .phone jammer can be covered and protected by the specific installation box
Adversely affect the development of the mobile machine industry. 2003 China and South Korea because of the garlic trade disputes, China's total ban on imports of South Korean mobile phone machine and parts, it is some of the domestic mobile phone companies make matters worse. Domestic mobile phone to go high-end line, you can spend a much higher cost to improve the original technology, the quality of the production of mobile phones is also a corresponding increase, coupled with their own unique selling points - such as TCL's gem machine, thus confrontation with the foreign brands in the high-end mobile phones. The statistics also show that domestic mobile phone sales in each product line the best in high-end mobile phones, the price is about 60 percent more than 2200 yuan.
