Transition in the corner or connection, the use of welding for optimal performance. To maintain continuity between the surface magnetic field lines can be guaranteed a low reluctance path along its row forward, this can increase the shielding effectiveness. In the exchange market to maintain continuity allows higher magnetic induced current shielding, in the DC field, the magnetic field lines for the appropriate shunt, continuity is important. If you are not close to the shield at one end or both ends, paying particular attention to the beginning of the one-diameter ratio. This shield length - diameter ratio should be at least 4:1, in order to avoid "termination effect" and the range of magnetic field lines penetrate the shield. Rule of thumb is extended to the need to shield the external device, so you can use with hole radius equal parts protection.The blocking radius range of cell phone jammer is dependent on signal strength of site working environment. Because of the increased length of the shield while maintaining the same diameter, you can use the infinite cylinder model approximation. When a cylindrical or rectangular shield needs a big hole, perpendicular to the shield wall of the tube can be used as shield openings caused by the reduction of the magnetic field strength.
Low-cost shield design the most important step is typical of these characteristics and shielding material understanding of the impact on the shielding performance. Once the appropriate material is selected, the focus should be concentrated on the basic design considerations, so that it is not only best performance, and minimal impact on cost. 3 Most of the shield design considerations and models with the development of the formula is based on circular or infinitely long cylinder geometry. In practice, the practice of a given shape of the shield and the shield from the device structure itself can be determined by the use of space. In the design of a shield, important to understand the structure is rotated 90 ° to make the magnetic field lines is difficult. cell phone jammer is also used in the prison, detention house, court, police station and so on which have requirements for the secrecy. However, the round shield, for example, to change the angle of the cylinder or a circular magnetic field lines of the box than the direction of the shield with square corners easier. Similarly, for the inclusion of magnetic shielding material has entered the line and change its direction, better rounded than the sharp corners. Maintained to provide a low reluctance path of the magnetic shield shape of a simple movement or the "minimum reluctance path" is very important. Shield the size of the shielding effectiveness and cost of great importance. The smaller the effective radius of the shield, the better its overall performance. However, the design is intended to shield the envelope and trying to shield the space components, and should be very close. cell phone jammer still can be used in such serious locations as the party and government institutions, enterprise meeting rooms, concert halls, theaters and so on which need tranquility.Since materials account for most of the shield design costs, smaller shield can be obtained at a lower cost on better performance. Whenever possible, shield wall should be close to all, to avoid field leakage. This structure (even rectangular) is closest to the circular, it can create a semi-closed magnetic circuit. In addition, all the cabinet can be shielded in all axes, so as to ensure the best shielding. When a special performance and import and export needs, removable cover, hood and doors can be combined into the design of the shield to go. In the use of cover, hood and doors or use two or more panels to build the shield, in many boards have maintained contact with the magnetic and electrical continuity is very important. cell phone jammer can block the signals of GSM/CDMA/DCS/PHS within the radius range of 1-20m. Can be mechanical (using friction components) or magnetic welding to maintain continuity.

Cell phone jammer can cut off inter-cell phone communication
Channel is borne water vendors, through which vendors can "flow" to the user, the water can carry a boat, can also capsize, channel structure is reasonable, water flow, it will seize the users according to market demand, the manufacturers enormous value; when the channel blocking occurs when the upstream firms will quickly fall into collapse. Domestic mobile phone makers should pay close attention to changes in the pattern of domestic sources, to establish a value-added transformation of consciousness at the core of the channel, and adjust their time to build their own distribution system can control channel resources and channel advantages, who can grasp the flow of sales channels and a huge sales network, who had the last laugh in the year. cell phone jammer will act in the whole working frequency range of cell phone. This rapid growth is bound to affect the global market, leading to reduced profits and the industry is facing the danger of competition. According to Gartner Dataquest research data show that consumers buy mobile phones worldwide annual average price fell nearly 10% since 1996 to $ 411 $ 206 last year. However, with the rapid growth of those new Asian firms gain economies of scale, they will be the mass influx of international markets, leading to further decline in handset prices. Beijing consulting firm MFC Insight's telecommunications industry analyst Peter. La Rock (Peter Lovelock) said that China's mobile phone manufacturers are contributing to the "mobile phone price all the way down, and accelerate the pace of decline in price." In contrast, Nokia is counting on its strong brand strength and technical innovation to a large number of new competitors from Asia stand out. cell phone jammer can cut off inter-cell phone communication.
However, although the Chinese mobile phone manufacturers has been lacking in technological innovation, but they compete in the market to bridge this gap by speed. Competition in the market right now, mobile phone manufacturers to consumers respond to changing preferences have become increasingly important, and business outsourcing model allows them to gain a greater advantage. MFC Insight's Laffer Locke said that this growth has forced the global industry giants to respond. "Nokia, Motorola and Samsung are increasing their number of models each year," he said, "This is directed at China (phone manufacturer) response." cell phone jammer is easy to control the covering range.
Gongzhufen is Beijing's largest mobile phone market, mobile phone giant Nokia ad placed in the most prominent position, and its aggressive advertising words would be: "Every time you blink an eye, Nokia has sold out of four phones." However, in this billboard are in the Chinese mobile phone market, is undergoing a change from quantitative to qualitative change. According to the Ministry of Information Industry, Economic Reform and Economic Operations Division provides the latest data, in the first quarter, overall sales of domestic mobile phone market has more than 50% of total sales. Although this data is not based on statistical sources first-hand mobile phone stores, but at least that made mobile phones is still relatively strong growth momentum continues. Motorola, Nokia, Samsung may be less this year better than the day to TCL, Bird, Amoi is the vanguard of the local phone companies in both camps clearly not satisfied with the performance. Communication between the cell phone and base station can be cut off because of cell phone jammer .
But it is equally clear that those who triumph in the domestic mobile phone companies in the star, will undergo more tests. Many Chinese have turned to the humble mobile phone manufacturing companies are the field quickly will have the basic functions of mobile phones into a mass commodity, and because the low prices of these companies on the market have been leading the industry out of the market risk. Still in the industry such as Nokia and Motorola dominated by a few global giants, which control 55% of the global market. However, in China alone more than 20 companies have entered this business, in just three years, they are in China's domestic market (the world's largest mobile phone market) share from almost zero to the level of a sudden surge 20 percent. This kind of calculation method of cell phone jammer is easy.

High-power electromagnetic radiation of cell phone jammer
Costs hereby (Marcel Fenez) said: "This advantage can be reduced (handset manufacturers) in the plant and machinery equipment investment, and avoid the risk of idle plant equipment there." High-power electromagnetic radiation of cell phone jammer is not harmful to people’s health. Lewis said that Nokia invested in this technology a lot of money, and that ordinary consumers are willing to pay extra fees for them. He talked about the acceptance of high-end services in poor condition, said: "This assumption has not been confirmed in the market." In Beijing, a wireless industry consultant David. Alm Strom (David Almstrom) that the majority of mobile phone users worldwide, especially in Latin America, Africa and Eastern Europe for the first time phone users still need to have basic communication-enabled mobile phones. The former Ericsson executives said: "China (cell phone) manufacturers have an advantage in these markets. That it is their long-term." Feedback messages from the market point of view, the current domestic brand mobile phones in consumers' minds awareness rising, domestic mobile phone in recent years continues to grow, in some areas has become a clear trend, forming a greater advantage, but at the moment in the development and growth of the domestic mobile phone also has some problems. cell phone jammer makes the cell phones in the specific area not be connected.
Recently in the "Beijing Youth Daily," held the first "Forum on China-made mobile phones", from Bird, TCL, Kejian, Amoi, Lenovo, Panda, Eastcom, Capitel made mobile phones more than a dozen other national representatives, and industry experts and with representatives of consumers, many of the current difficulties of domestic mobile phone issues were discussed. Telecommunications Science and Technology Information Institute, deputy director of Song Tong in his speech, very representative summed up the domestic mobile phone market is currently emerging characteristics. Communications market in China for many years maintained a momentum of rapid development, causing the domestic mobile phone manufacturers concerned. There are many companies converting domestic mobile phone plan initiatives, especially those of foreign companies, there is still a joint venture to do business plans. Take the GSM system influenced by cell phone jammer for example in this text.
These effects in China low-cost, high-volume manufacturing environment has been enlarged, so that from the TV to mobile phones and other electronic audio products, lower profit margins in China embarked on the road to mass production. hilips Semiconductor responsible for the supply of chips to handset manufacturers group senior vice president of Peter. (Peter Baumgartner), said: "I fully believe that Chinese companies will control the (global) low-end mobile phone market." However, China does not have a mobile phone brand in London or New York can be one to compete with Nokia. The growth in domestic demand led China mobile phone manufacturers everywhere, China is still a month to add about 300 million mobile phone users. However, the Chinese mobile phone manufacturers need to integrate first, then it may be the birth of a sufficient size companies, directly to the industry leader in the international market, issued a challenge. cell phone jammer may interfere with the mobile communication base station.
Motorola and other mobile phone manufacturing giant this understatement, that this threat is limited to low-end phones, said they will continue to offer (newer) technology to maintain their leading position. Motorola in Hong Kong responsible for the technological innovation strategy, marketing director Stephen Tsao said that the current mobile phones tend to include more rich functionality. He expects to increase through the mobile phone camera, music, Internet and video games and other functions, Motorola's handset business will maintain its profit margins. Some analysts said that these attractive features (whether to play the role) has not yet been confirmed. London telecom consultancy ARCchart Ltd.'s Analyst Matt. cell phone jammer may even palsy the communication base nearby.

Cell phone jammer received during communication can be divided into the following
The cell phone in a cell contacts with base station through the uplink frequency of the channel during communication and this process can be influenced by cell phone jammer . Strategy for the use of large-scale companies, each on a scale level, the unit cost will decrease, while the decrease in cost compared to the sharp decline in prices has laid the foundation for this strategy opened the opponent's distance, to obtain maintain a competitive advantage and the foundation. In this case, unless the competitor can form a significant difference in the quality of technology, in a smaller market to obtain a small profit in order to withstand the impact of this price. This result is a large number of small and no significant difference in technology companies will exit the mobile phone market. Low-end mobile phone manufacturers market competition, on the one hand to expand the production scale, increase market share and maintain healthy growth. Every frequency range which might be blocked by cell phone jammer contains many channels of the certain bandwidth.
On the other hand, the market demand is constantly changing, and only suitable for users to meet user needs, always grasp the pulse of the market, increase innovation, in order to maintain the freshness of the consumer, in order to meet the mobile phone market, the pursuit of the new consumer trends . The new face of the new low-cost handset market trend, "the scale of + innovative" state-owned foreign brands brand competition, competition in an invincible position in an effective strategy. Rely mainly on the establishment of brand image advertising advantage, high-quality product quality and perfect after-sales service. Every cell where might install several cell phone jammer .
By the scale of operation, expand markets, reduce operating costs and increase investment in technology to enable enterprises to improve competitiveness. In the specialized field of bigger, stronger, through the scale must depend on the support. Technology investments must be based on the formation of scale on the basis of comparative advantage. Why foreign companies can easily invest billions to develop mobile technology? And why the Chinese mobile phone manufacturers can only imitate, to follow up? The underlying reason is the size of production. Determine the size of the product cost sharing (including: technology development costs, production operating costs, cost of sales promotion, etc.), technology development needs of technical input, technical input on the need to share in each product. And then, the signal can be turned to MSC to realize communication with the other cell phone or telephone which can be shielded by cell phone jammer .
Production of 10 million mobile phones the size of the company (on a per cell phone sale price of 2,000 yuan) sales income of 200 million, 10% of the 200 million investment in technical development, sharing an average of 20 dollars per phone. For there is no scale companies, such as 100 million mobile phones the size of the company producing the same 200 million investment in technical development, the average 200 dollars per phone sharing, it is clear even if the investment does not produce anything competitive. The other hand, Motorola, Nokia, represented by foreign brands, the low-end mobile phone market long dominated the vast majority of market share, just keep the momentum of innovation, has introduced consumers to new products, we can maintain and even expand market share. The radio frequency which might be jammed by cell phone jammer received during communication can be divided into the following according to the frequency range.

The cell phone can not send information outside
Effectiveness and connection of the whole network covering range which can be influenced by cell phone jammer should be considered. With the rapid development of Internet in China, making people's lives become increasingly inseparable from the network, more and more dependent on the network to bring the convenience, or because most people use desktop computers, laptop wireless Internet access technology is not really been implemented, people put the needs of sustenance to the phone. Therefore, wireless Internet, send and receive E-mail, mobile QQ, multimedia messaging and other functions has become a major market demand. GPRS and W-CDMA handsets for the sudden emergence of KJava present, many manufacturers use a wide range of applications KJava to write software programs, the development of stocks, games, shopping, remote control, infrared transmission products such as mobile extensions, to promote consumption those of the entertainment needs. It should be noted that, color, rotation, etc. there is a voice and MMS mobile phones look and function of innovation, but also attracted a new group of "chasing the new family", especially the "polyphonic music," singing the entire 2007 In the mobile phone market. Other channels are called the traffic channel which also can be blocked by cell phone jammer .
Product integration is the basic trend of product development, functional integration on the one hand the performance of mobile phones and other digital products, integration, the formation of mobile multimedia terminal, on the other, communications and computer products, home appliance convergence. If consumers FM tuner, MP3 and other functional requirements have been emerging trends. Design competition in 2006, the focus of one of the mobile phone market, innovation and competitive differentiation is the key to winning. It can be seen, most of the needs of the market demand is an extension of the previous year, so that the integration of phone features and the pursuit of diversity will be the next trend. The cell phone can not send information outside if cell phone jammer is used.
Therefore, only 18% of mobile phone with Internet access, has not been very widely used. SMS rates are cheaper, so SMS will always be demand for the hottest features. Although the concept of mobile phone consumers have been great changes, but the functional requirements still in relatively early stage. In 2008, Chinese mobile phone market continued to expand, which means the phone is a stylish appearance of the basic requirements of individual consumer, the consumer phone features, the pursuit of style is intensified. Appearance is still a hot pursuit of the consumer. The pursuit of the appearance of mobile phones has been reflected in 2001 on, but then focus on the style to light, narrow, short, small, and the color is relatively small, mostly stay in the black, blue, white, gray and four colors, consumer can choose the range is not very wide. However, the cell phone will generate some problems which can not be ignored so that cell phone jammer has to be used.
To 2007, manufacturers are firmly grasp the people of this consumer demand, mobile phone design with soft tone multi-color-based, while the emergence of red, purple and other bright colors, can be described as colorful, but also in appearance showing a trend of small, thin, won by consumers. Ringtones / download pictures, light / sound identification calls, adjustable backlight and other functions has become a hot topic sought after consumers. Is not difficult to see that these functions are used to dress the primary means of phone, personal cell phone is the pursuit of fashion trends at the time, coupled with consumers the freshness of these new features, these features undoubtedly become the biggest winner. The cell phone can not use the network due to use of cell phone jammer .

The corresponding cell where cell phone jammer
cell phone jammer is easy to control the covering range.
Moreover, the technology in broadband wireless communications field, including a large number of high-tech knowledge content, from system architecture, all-optical networks, protocol structure, coded modulation, multi-site connections, to decline against the detection process, and many other aspects of personal terminal, set signal system designed to handle the latest in modern technology and baseband, IF and even the high-frequency, optical and other VLSI technology processes in one, there are a lot of room for innovation there, and there is a corresponding economic value of intellectual property rights. In this regard, China's manufacturers, the operator operator, research departments and investment are required to establish a close strategic partnership. Recently some manufacturers from frequent moves, cell phone price war will burn in the recent war in the high-end market. Every base station which might be influenced by cell phone jammer contains the transceiver.
Of course, ultimately depends on the mobile phone industry competitive products, advertising sold well, also the game is that the product can not keep up. There are indications that the war made high-end mobile phones already start a prairie fire, recent large-scale fights may be imminent. According to statistics, 21-25 ,26-30-year-old two-year-old consumer group is the main force of China's mobile phone market, and its proportion has reached 46% in 2007. The fashion is to embody the personality characteristics of young people, and for more emphasis on the choice of mobile phone handsets can show their personality style. Therefore, the demand will take on the appearance of an increasingly important position. The late 1990s, the Chinese mobile phone market in the cultivation of market development period, mobile phones at the time was noble, a status symbol, but with the changing perceptions of consumers on the phone, they really need the phone for the Chinese people, Chinese input also increasingly important. The cell phone brings hidden risk to the enterprise’s safe production so that cell phone jammer is also used and installed in the workshop or factory.
Well, as TD-SCDMA should create a favorable environment for development, support their own technical standards. However, this support is not unlimited, the final choice or according to the laws of the market, not blind support. Develop its 3G manufacturing industry, can also mimic the path taken by program-controlled switches, namely the introduction, digestion and absorption. This approach is the essence of open trade, in accordance with rules of the market, through the market economy to achieve survival of the fittest. Of course, national communications enterprise technology capabilities, can greatly shorten the process. Now, with ZTE, Huawei, as the representative of the national telecommunications companies have in some ways have the ability to par with international standards. cell phone jammer will output voltage via transformation rectifier.
View from the resource potential of broadband, third generation mobile communication frequency band, to expand from its core band frequencies, are subject to the following 3GHz. From L, S, C, X, Ku, Ka to V / Q / W, EHF may extend the practical, and more broadly Radio (several kHz-3000GHz) to Wi-reless (greater than 3000GHz), the future Wireless infrared light and blue light may reach the band, as well as particles like neutrinos communication connection, Air Optical like free-space optical (FSO) broadband wireless access system that is for example. Thus, broadly Wireless (Wire-less) communication concepts of view, the broadband and broadband resources will also be showing a broad space for development. Under the standby condition, the cell phone can intermittently start the receiving circuit to receive BCH in the corresponding cell where cell phone jammer .

The calculation of shielding range of cell phone jammer
The whole covering range of all base stations influenced by cell phone jammer equal to the integral arrangement of adjacent regular hexagons. Although GSM has made a huge commercial success, but its technical limitations to the capacity has been limited, making it cost in the system and CDMA system in the future will compete at a disadvantage. It should be noted, GSM's success is largely due to CDMA products were not mature enough in key technologies (distance effect, power control, etc.) there are obstacles, coupled with the success of the European decision-making in the standardization work, only the GSM Born on the When, as in the early 1990s, analog cellular telephone system upgrade only option to obtain a rapid spread of the world. China already has the world's first large-scale telecommunications networks, but the size of the telecommunications industry is not the largest. Explore new telecommunications business growth, to grasp the future direction, 3G is the greatest significance. Actual working range of every base station influenced by cell phone jammer is the regular hexagon (also known as the cell).
Currently, around divergent views on the timing of 3G development, mainly due to the current development of 3G is not so urgent, so allow a lot of views exists. If you need to do to a unified conclusion, the state will have a very practical, considering the many factors that the implementation plan. Steady development of China's need for 3G, in global terms, even if the license has been issued in Europe, nor to all the human and material resources to go 3G. According to the study of the situation in Europe, the development of 3G in Europe is not completely unified view. Basically, many operators and manufacturers in a positive way to keep track of 3G, and the development of 3G, but are in a relatively passive. Because the 3G business model, profit outlook is not so clear. It is the calculation of shielding range of cell phone jammer .
With the development of information society, the rapid popularization of Internet applications, the demand for high-speed data transmission has become increasingly urgent in the wired communications network, data traffic has been a worldwide trend to catch up voice communications. Expected in the mobile communication network, data traffic will also be in the near future than voice traffic. The formation of an integrated global broadband multimedia mobile communication network will be the trend, wireless transmission of data will greatly expand the people's living and working space; and this trend will also allow the integration of global broadband communication systems ─ ─ wideband CDMA quickly from experimental room into the practical stage, its application will enable the integration of global broadband multimedia mobile communications can be achieved. The cell phone facilitates people’s life but cell phone jammer is still needed.
Optimistic estimates, next year China Unicom will launch CDMA, which communications equipment manufacturers, that means a new competitive platform, the competitiveness between the companies will therefore be considered. CDMA was China's "863" key projects, as early as 1994-1995, the authorities of the technical staff began to research its key technology in 1997, Great Wall in Beijing, Shanghai, Xi'an, Guangzhou, established four commercial experimental network. Since the experimental nature of the network, so its growth rate is not fast. Two years ago the company announced the development of China Unicom CDMA, but only until August 2000 becomes clearer, CDMA in China painstakingly. Today, China is still in the analog wireless networks, GSM and narrowband CDMA coexistence phase. Which is gradually declining TACS, GSM momentum is busy (now about 95% of users are GSM network), CDMA is gradually put into commercial use. The cell phone threatens the confidential information safety so that cell phone jammer is needed to prevent this phenomenon.
