Focus on supplier enterprises is the main concern of the bargaining power of suppliers. The supply of bargaining power will affect the degree of competition in the industry. Between the purchaser and the manufacturer, supplier, whether at a reasonable price, better product quality, provide better service, timely delivery and reduce costs directly affect the interests of the manufacturers. The globalization of economic and trade situation, the production of many commodities have implemented global sourcing, global production and global sales. The phone is no exception. In addition to some of the key software and core technology by the companies themselves design and development, most of the other components, and even some of the key chips are a way of outsourcing or outsourcing. This equipment of cell phone jammer is mounted in the case.
The current national focus on encouraging the development of industries, products and catalog a series of policies issued and implementation, to create favorable conditions for the development of China?s mobile phone industry. Increased year by year, the demand for mobile phones is increasing, and promote the rapid development of China?s mobile phone industry, to promote China?s mobile phone industry chain from scratch, from small to large, from the total expansion to the upgrading of the structure, and gradually formed a diversification with Chinese characteristics improve the efficiency of the industrial chain of multi-level system. After nearly 10 years of development, China?s mobile phone industry chain gradually improved, with a large number of component manufacturers and EMS manufacturers, trained a large number of high-quality, relatively low-cost engineers and industrial workers, has accumulated a solid technical foundation. The exported elements are utilized forcell phone jammer.
Chinese mobile phone an annual capacity of 2004 exceeded 170 million mark, while the total market capacity is only 69 million units, the middle will have to deduction of no small proportion of the mobile phone market (in Guangzhou and other places, and second, the proportion of a conservative estimate more than 20%). According to the view of modern marketing, product characteristics is a key factor in the impact of marketing decisions.

It can prevent the intentional and unintentional damage tocell phone jammer.
The CDMA network is a new technology, mobile communications network, the CDMA frequency usage rate, can be 4-8 times more than the GSM, ITU has been determined that the underlying technology of 3G CDMA. As the transition to third generation mobile communication 2.5G technology, it portends the future development trend of mobile communications. Government to Unicom?s CDMA frequency of 10 trillion, so at least the equivalent of 40 trillion GSM network frequency due to the high spectral efficiency of CDMA, which is able to accommodate at least 300 million users. CDMA phone up to several hundred billion dollars brought in the consumer market, the domestic mobile phone companies and foreign mobile phone companies to the same starting line: the same technical background, have adopted Qualcomm?s core technology. The inverter used forcell phone jammer is AC220V-DC27V.
