Phone operating systems are generally only used in high-end intelligent phone. Currently, in the smart phone market, China's market-based mobile personal information management is still dominated, as more vendors to join the competition in the overall market has started showing a decentralized situation. Capacity from the market, competition, and applications of point of view, the market is still in start-up phase. Currently used in mobile phone operating systems are PalmOS, Symbian, Windows CE and Linux four. Palm OS operating system developed by Palm's own, and licensed to Handspring, Sony and Qualcomm, and other equipment manufacturers, the operating system is more inclined to the PDA operating system. More cell phone jammer will be equipped in other workshops.
Palm OS PDA market in a dominant position. Palm's product line itself, including smart phones, has announced the first smart phone developers Handspring acquisition, while independent software sector. Symbian is a real-time, pure 32-bit multitasking operating system with low power consumption, small footprint, etc., are very suitable for mobile phones and other mobile devices, through continuous improvement, supports GPRS, Bluetooth, SyncML, and 3G technology . The most important thing is that it is a standardized open platform, anyone can develop software support for Symbian devices. The difference is that with Microsoft products, Symbian mobile devices will be common technology, which is the operating system kernel. The cell phone jammer system is more suitable for the classroom of the school.
Separated with a graphical user interface technology, can well adapt to different ways to enter the platform, you can also enable manufacturers to make their products more user-friendly interface, in line with the trend of personalization, which is the user can see the different looks of symbian system is the main reason. Now provide a platform java process has begun prevalent on the Internet. Users can install the software, expansion of mobile phone functions. In Symbian development stage, there have been three branches: namely, Crystal, Pearl and Quarz. The first two major markets for the communications device, but also in most mobile phones, smart phone operating system in the future the main force. The detector of the management system of cell phone jammer can detect the signal.
The first mobile phone based Symabian system is a listing of 2000 Ericsson mobile phone models. The more mature at the same time the real draw attention to the market is the Nokia 2001 and 9210, it uses a Crystal branch system. The 2002 launch of the Nokia 7650 and 3650 is Symbian Pearl sub-system models, in which 7650 is the first 2.5G network-based smart phones, they all belong to the Symbian 6.0 version. Sony Ericsson introduced a model also used the Pearl Symbian branch to the 7.0 version has been developed, is designed for the development of 3G networks, can be said to represent the most powerful mobile operating system. The management system of cell phone jammer is useful, effect and intelligent.
In addition, Symbian started from version 6.0 to support external storage devices, such as MMC, CF card, making it a powerful extension capabilities into full play, so that store more software and a variety of large-capacity multimedia files as possible. Windows CE system, including Pocket PC and Smartphone, the former for wireless PDA, which is designed for mobile phones, there are a number of new mobile phone from the IT industry manufacturers to use, fast growth rate.

Cell phone jammer can be used indoors and outdoors
The WMA is short for Windows Media Audio, which is equivalent ASF file that contains only audio. WMA files in 80kbps, 44kHz mode compression ratio up to 1:18, and VQF basically the same. And double the compression rate than MP3. So it should be more competitive than VQF. MP3 music in order to prevent increases in the cost charged by the patent, GMGI the iCast's programmers developed a new free music format Vorbis, and MP3 the sound quality can be comparable or even superior to MP3. cell phone jammer can be used indoors and outdoors.
And will be released through the network, you can free download free, do not have to worry about copyright infringement issues. However, MP3 has been very popular on the Internet, Microsoft's Windows Media technology began to spread, Vorbis is still not optimistic about the prospects. APE is a lossless audio format. Large WAV audio files can be Monkey''s Audio software for this "downsizing" compression for the APE. Very often it is used for network audio file transfer, because the APE file to be compressed WAV source file capacity smaller than half can be used to save transmission time. More importantly, by Monkey''s Audio extract the WAV files to be restored after and before compression can be done exactly the same source file. The gain of GSM/DCS omnidirectional antenna of cell phone jammer is 1-2dBi.
Therefore, APE known as "lossless audio compression format", Monkey''s Audio as the "lossless audio compression software." WinZip or WinRAR and use such specialized data compression software to compress audio files of different compression after APE audio files can be played. Monkey''s Audio Winamp will install a "in_APE.dll" plug-in, so that Winamp also has the ability to short play APE files, APE is a lossless compression is now the best audio format. The maximum output power of cell phone jammer is 6dBm.
And, like MP3, RA these widely popular compression format generally only 1:12 or so. But still will not affect the sound quality, when VQF to 44kHz-80kbit / s audio sample rate compressed music, its sound quality will be better than 44kHz-128kbit / s, MP3, to 44kHz-96kbit / s compression, the music close to 44kHz- 256kbit / s for MP3. MD (ie MiniDisc) is introduced by SONY in 1992, a complete portable music format, it is the ATRAC compression algorithm used in technology (compression ratio is 1:5). Type is divided into recordable MD MD (Recordable, a laser head and the first two heads) and a single open-end MD (Pre-recorded, only the laser head). The imported elements can keep the high integration of cell phone jammer .
Powerful editing functions are MD's strengths, you can quickly selections, track move, merge, split, delete and title editing and many other features, more personalized than the CD, you can always have an album of their own MD. MD Walkman products including MD, MD bedside audio, MD car audio, MD recording deck, MD camera gun and MD drives. That is, CD's, a CD can play 74 minutes or so of sound files, Windows system comes with a CD player, sound card included with most other software for CD playback, and even some of the drive from the computer, as long as access through the power supply can be used as a stand-alone CD player to use. cell phone jammer can be conveniently fixed to the tripod.
Microsoft is developing its own network multimedia service platform to push on the main ASF (Audio Steaming format), which is an open support in a variety of network and data transfer protocol standard. It supports audio, video, and a host of other media types.

To improve the quality of cell phone jammer
In recent years, Nokia has been suggested that enterprises with a cell phone instead of the original desktop telecell phone system (ie, PBX, the English abbreviation for the PBX). Nokia claims that this can greatly improve efficiency and save the desktop call management expenses, as are outdated desktop cell phone that no one be used again. But few companies approved Nokia's point of view, PBX sales are still growing. In fact, just the cell phone business as an integral part of business communication. Nokia seems to give up, and thus changed his story. Nokia's enterprise voice business executives Jacques ? Aoke Ning said: "For large enterprises using wireless communication technology is just unrealistic, fixed-line telecell phone has its place." Nokia claims that change is the emergence of the trend of convergence of fixed and wireless, This is the latest telecom industry boom. Many experts of cell phone jammer devote much spare time to improve the quality of cell phone jammer .
Supporters claim that this convergence of mobile and wireline services to break the barriers between so that all save money while promoting the introduction of new services. But in reality there is no integration of the basic service, which is the Nokia cell phones that use the existing access to PBX services charm. Aoke Ning said: "there are around 430 million PBX lines and about 200 million cell phone business and our goal is to win market share in fixed telephony." Nokia hopes the market leader with Avaya and Cisco deal to speed up this work. "I see between the fixed and cell phones conflict, rather than integration", consulting firm Quocirca principal analyst Rob ? Ban House, said: "This will cause damage, some companies will fail, even big companies must be two-pronged approach to avoid the loss so that we see once impossible 'Sleeping in bed' of the two technologies in close to each other. " The factory praised the technical staff members in successfully researching the technical problems of cell phone jammer .
Avaya and Nokia signed a cooperation agreement, is the strategic transformation of the most convincing case. Nokia to 60 kinds of commercial software developed series of cell phones, making Avaya's PBX users can use a simple graphical interface to all the features of office systems. Cell phone itself has become another PBX extension. PBX functionality and mobility will combine the needs of the enterprise there is a long time, few mobile service providers to meet this demand. Integration of independent companies will deal with this problem. Business is not really wish to assume this responsibility. "System integration requires a complex infrastructure, many companies want to pay for the service provider management of such services." Aoke Ning said. Quocirca, a survey shows that IT executives in Europe, 70% of the services provided by the service providers interested in, which is a by the PBX as the host, will be tied up wireline and wireless communications services. The aluminum alloy heatsink and a fan can help with the heat dissipation of the channel of cell phone jammer .
PBX Another advantage is the system that can reduce costs because the system can call free of charge in the internal communication network transmission, without the need through the public telecell phone system. In contrast, cell phone roaming charges due to charge transfer fees and the Internet, usually the most expensive form of communication. Nokia estimated mobile voice communications in the enterprise ICT spending accounted for 10% -25%, which is higher than any other business systems, including SAP and other costly systems. Telecom users to organize the Union of European Virtual Private Network Xi Aide ? Funk said: "Mobility is a key element composition of staff efficiency, but the cost is high. Mobile environment should be suitable for private fixed-line environment, in order to reduce costs." cell phone jammer can work continuously without any break.

Cell phone jammer has the real time function
In the wired network world, a place in the mobile commerce industry coveted piece of the pie, and not enough time to seize the initiative in the wired network who want to create another piece of the sky. While we are all full of enthusiasm, dedication to put into action when the business market, Ovum's analysts believe that the action painting of a large business piece of the equipment suppliers on the one hand just wishful thinking reflects the desire, the other is related interest groups could wish for dreams. cell phone jammer has the real time function.
With mobile commerce value chain can help the reader understand the location of the relevant industry and value creation advantage, barriers to entry and market structure in the network set up by the wireless hardware gradually to content, retail / distribution industry decline and open, the future will show more and more Web content presented to the user, there will be more and more businesses join the ranks of the wireless business, really convenient for the state. In this special emphasis, the wireless business at this stage just as the other e-commerce transactions cable channel, and will not replace wired e-commerce. Installation of cell phone jammer adopts wall-mounted installation.
In the back-end transaction process is carried out with the cash flow, logistics systems link, which is the most critical business operations of a ring, but also in the wired Internet in the weakest link, how to learn from past experience is important the subject. Suits affecting the environment variables can be divided into surface, technical and application side, actions of these factors also determine the time and opportunity to carry out business. By the second-and third-generation mobile network profitability trend can understand, with the evolution of communications technology, profitability of carriers will gradually decline, but the content providers and mobile commerce will benefit the entire industry, the spindle This is because in the past the emphasis is on communication system voice services. cell phone jammer has been installed on the ceiling.
The future of telecommunications services in addition to voice services, data transmission and a more mobile business is a big business. Therefore, everyone competing carriers and mobile content business into other areas, expect profits to maintain or even expand, this phenomenon has resulted in mobile commerce market is becoming more competitive, Who was the last winner, remains to be seen, but the entire operation business market is also facing a number of bottlenecks affecting the development of mobile commerce. In the wired Internet world, because a large computer screen, enter the convenience, speed transmission, most of the content is free to read and other factors, make people use wireless devices, the feel suited. Observed in Japan, Western Europe and North America's Internet market, can be found in Japan, Western Europe compared to North America is concerned. cell phone jammer is due to interfere with the mobile communication downlink signal.
Internet usage is not as wired wireless network, so the people when in contact with the wireless Internet more easily met. Taiwan's cable penetration rate has reached 25% of the network of about 557 million people, it is introducing mobile Internet services, have a greater resistance. According to estimates of the relevant industry, education and public use of wireless Internet access for business conduct takes about three years, because to change the user's consumption pattern is not a simple task. Taiwan-commerce related businesses are currently feasible approach is to lock the main customers in the enterprise customer, because the current wireless network than a wired network using a high fee. cell phone jammer position should be energized from the nearest power supply.

Cell phone jammer is easy to install and operate
There is a working indication light on the panel of cell phone jammer
However, there are various cell phone brands technical incompatibilities, often only in the actual use of cell phone brands in the same room with each other to achieve the above transfer, the utility needs to be further improved. With the color of the increasingly popular cell phones, cell phone screen material is also more important. LCD color screen cell phones because the quality and R & D vary, the types generally have TFT, TFD, UFB, STN and OLED are several. Generally speaking, the colors can be displayed to show the more complex images, richer level of the screen. cell phone jammer is easy to install and operate.
Remove the top LCD outside these categories, but also in some cell phones to see some other LCD, such as the Japanese SHARP GF-screen and CG (continuous crystalline silicon) LCD. Two kinds of LCD compared to a completely different kind, GF for the STN improved, to improve the brightness of the LCD, while the CG is to achieve high-precision high-quality LCD QVGA (240 × 320) pixel size resolution. STN is a key component of early color, was only able to display 256 colors, even after transformation can display 65536 colors or 4096 colors, but now the general is still 256-color STN, the advantages are: low cost, low energy consumption. cell phone jammer can jam the WiFi signal.
TFT's brightness, high contrast, strong sense of hierarchy, bright colors. The disadvantage is more power, higher cost. UFB is specifically designed for cell phones and PDA's screen, it is characterized by: slim, high brightness. You can display 65,536 colors, 128 × 160 resolution can reach a resolution. UFB display uses a special grating design, can reduce the pixel pitch for better picture quality. STN and TFT UFB combines the advantages of: less power than TFT, and STN similar price. STN (Super Twisted Nematic) screen, also known as super-twisted nematic liquid crystal display screen. In the traditional monochrome LCD display to add the color filters, and color of each pixel in the display matrix is divided into three pixels. cell phone jammer is easy and convenient to slip into the pocket.
Were shown through the color filters red, green, and blue, this color to display the role of color to light green and orange for the main. STN screen is reflective LCD, it has the advantage of power consumption, but in a dark environment, clarity is poor. STN is our contact with the most material types, there are mainly divided CSTN and DSTN, it is a passive matrix LCD devices, so the power consumption, energy saving, but what should be a slower time for 200 ms. CSTN commonly used delivery methods lighting must be used outside illumination, known as backlighting, lighting to be installed behind the LCD. cell phone jammer is good at shielding the signal of cell phone.
TFT (Thin Film Transistor) that thin-film field-effect transistors, active matrix liquid crystal display is one. It can be "actively" on the screen to control each individual pixel, which can greatly improve response time. Generally faster TFT response time of about 80 ms, and the viewing angle, and can reach 130 degrees, mainly used in high-end products. The so-called thin-film field-effect transistor, liquid crystal display is the LCD pixels are each integrated in the subsequent thin-film transistor to drive. Which can be high speed, high brightness, high contrast display screen information. The proper version of cell phone jammer appropriate to the occasion should be chosen

This type of cell phone jammer permits you easily to operate
Infrared communication technology has been a number of worldwide support and the use of software and hardware vendors, currently the mainstream of software and hardware platforms offer support for it. Infrared technology has been widely used in mobile computing and mobile communications devices. DAB digital audio broadcasting (Digital Audio Broadcasting) abbreviation. cell phone jammer can cover a range of 40m.
DAB is the second amplitude modulation (AM), frequency modulation (FM) radio broadcast after the third generation technology, is a new digital broadcast system, give us a CD-quality audio broadcasting experience. Cell phone work in the waiting state called standby. Battery standby time is the cell phone standby mode in continuous use. Can also be interpreted as a cell phone fully charged battery, without a call, do not shut down the standby mode, the battery has been consumed by its own low-battery warning to appear between the time that can be sustained. Standby current consumption is relatively small, almost nothing to do with the network, according to different models, the current consumption to a few tens of mA mA range. Standby time depends on battery capacity and the size of current cell phone consumption. This type of cell phone jammer permits you easily to operate.
The standby time of algorithm: cell phone battery capacity / standby operating current = standby time. And the manufacturer's standby time is only a test data, the actual standby time will be affected by many factors, such as the battery capacity, the use of state cell phones, network signal strength and so on. The main impact of standby time factors include use of the environment, the battery performance and quality of the cell phone itself, for example, if the relatively poor weather conditions use the cell phone, the cell phone will need to increase the power of the method to maintain signal transmission, thus increase big cell phone battery power. Quality of the cell phone, if the cell phone battery and cell phone contacts appear to be dirt or oxidation. cell phone jammer will only jam your immediate surroundings.
This will adversely affect the cell phone's internal parts, power consumption also increased at this time, will also affect the cell phone's standby time. Affect the standby time is a complex issue, but overall, mainly by the following factors: the actual effective capacity of the battery current, and charge the full extent of the inherent static standby power mobile SIM card types, different types of chip technology and the SIM card a far cry from the current work, the new 1.8V/SIM only a fraction of the 5V/SIM card. The SIM card in the machine power occupy a considerable proportion. GSM feature is that all the data stored in the SIM card, you can be personal data, cell phone number, telecell phone contacts and other information stored in them once the cell phone or get a new machine failure, as long as you can swap cards all the data conversion. cell phone jammer can disable the spy recorders around.
But too much information on the SIM card cell phone will from time to time to read the data, can also cause power loss. Transmitted by the cell phone network as well as efficiency of the system. According to the GSM system design, cell phone base station transmit power according to the instructions will automatically adjust the cell phone far away from the base station, or in a signal shadow area, or cell phone transmitting antenna system efficiency is low, the cell phone will have to transfer large transmission power, then the mobile power will be multiplied. And not to say that when the cell phone call was launched, usually cell phones and networks have to keep in touch regularly report to the network work, so the network and mobile antenna systems for cell phone standby time also plays a very important role. cell phone jammer is ideal for a large room, restaurant and cinema.

Cell phone jammer has passed the testing
Advertising model: flowers or leaves? Either Yahoo, Sina's "gateway mode", or Google, Baidu's "search mode", the embodiment of all advertising model, although different forms of advertising model may show ads may be keyword advertising. Graduate Institute of vice president of Internet experts Lvben Fu believes that the cell phone screen is much smaller than the PC, the richness of the content of ads will be greatly weakened, and this determines the mobile Internet advertising model will not be the most mainstream of the business model. Also, cell phone users more time online time is fragmented, for example, on the road, waiting time, which also determines the ads will be greatly weaker than cable Internet. However, many practitioners or the mobile Internet advertising model has high hopes. It is the latest revision of the working instruction of cell phone jammer .
Quality Assurance Department plans to hold a meeting to discuss the quality feedback of cell phone jammer from the customer.
Survey found that individual officers and soldiers who have been directly or indirectly Click pornography sites. Can be seen, the officers and men in the enjoyment of the Internet open, interactive, virtual and hidden advantages, but also easily lead to weakening of self-awareness, affect the health and moral inclination purity. Third, if the officers and men addicted to the network just affect physical and mental health. Curious young men, filled desire for knowledge, eager to exchange contacts, the pursuit of lifestyle, the richness of the Internet, privacy, interaction, entertainment and so on just to meet the needs of young officers and men, the officers and men very attractive. If the officers and men self-control is weak, poor discernment and external constraints is not strong, it is easy to indulge the network unable to extricate themselves, lose themselves. cell phone jammer has passed the testing.
Fourth, the loss may cause leaks. Several possible situations: one is chatting, participating in the network interact to open their own military capacity, was discovered and the use of enemy elements in its induced leak; one is vanity, chat with friends and family or friends when , the master of the military secrets of the capital as a show off, causing leaks; then one is too involved in the official store of information on the Internet, mobile storage devices, is enemy to steal. Awareness is not strong young men, but more or less understand some of the military secret, in the communication process can easily become the enemy of hunting target molecules, causing serious loss of leak problems.

Quality Assurance Department plans to hold a meeting to discuss the quality feedback of cell phone jammer from the customer.
Survey found that individual officers and soldiers who have been directly or indirectly Click pornography sites. Can be seen, the officers and men in the enjoyment of the Internet open, interactive, virtual and hidden advantages, but also easily lead to weakening of self-awareness, affect the health and moral inclination purity. Third, if the officers and men addicted to the network just affect physical and mental health. Curious young men, filled desire for knowledge, eager to exchange contacts, the pursuit of lifestyle, the richness of the Internet, privacy, interaction, entertainment and so on just to meet the needs of young officers and men, the officers and men very attractive. If the officers and men self-control is weak, poor discernment and external constraints is not strong, it is easy to indulge the network unable to extricate themselves, lose themselves. cell phone jammer has passed the testing.
Fourth, the loss may cause leaks. Several possible situations: one is chatting, participating in the network interact to open their own military capacity, was discovered and the use of enemy elements in its induced leak; one is vanity, chat with friends and family or friends when , the master of the military secrets of the capital as a show off, causing leaks; then one is too involved in the official store of information on the Internet, mobile storage devices, is enemy to steal. Awareness is not strong young men, but more or less understand some of the military secret, in the communication process can easily become the enemy of hunting target molecules, causing serious loss of leak problems.

Completion of installation of cell phone jammer
cell phone jammer can work when pressing the switch of power supply after finishing connecting the equipment. Predict the shielding effectiveness of below 4.2 will apply this algorithm to predict the shielding effectiveness of box analysis, that the shielding effectiveness and the hole size, the angle of the incident. In this paper, holes of different sizes, different incident angles, the application of modified matrix pencil algorithm for simulation analysis, the shielding effectiveness versus frequency curve. Width of the hole were taken 2mm, 5mm, 7mm simulation, shown in Figure 4-1. Analysis shows that: When the hole width is 7mm, in 0 ~ 600MHz low-frequency range, the shielding effectiveness is 27 ~ 40dB. Anti-interference ability, good shielding effect. Shows that the metal box with holes on the low frequency signal has good shielding ability. When the frequency of the resonant frequency of 715MHz, the shielding effectiveness of the smallest box, equipment cabinets at this time the most vulnerable to outside interference.The cell phone in the shielding range will lose signal from the base station for cell phone jammer .
Therefore, the actual design of the box, you should avoid important components of electronic devices placed in the vicinity of sensitive resonant frequency band, band-stop filters can also be used to eliminate high frequency near the resonance frequency interference. Comparison of three curve analysis: When the hole width is constant, the frequency increases, the shielding effectiveness decreases. This is because the frequency increases, leading to smaller wavelengths, so the electromagnetic wave is relatively easier to enter through the small hole inside the shield, and then produce electromagnetic interference. At the same time, you can see: the same frequency, the smaller the width of the hole, the greater the shielding effectiveness; the width of the hole bigger, the smaller the shielding effectiveness, shielding effects worse.
Used for cabinet doors, covers or lap joint of the connection. (4) conductive foam lining conductive foam lining with a low pressure, and good shielding effect. Its shielding effectiveness can be more than 90dB. High sensitivity of the equipment can be used to shield areas. When the waves encountered when conductive foam lining objects according to their nature of reflection and absorption, but also the equipment play a buffering effect, therefore, to achieve better shielding effect. 4 conductive particles of conductive particles is particles (such as silver-plated glass particles, silver particles, carbon black particles, nickel-silver particles, silver particles of aluminum, nickel-plated graphite particles, etc.) incorporation into the silicon Among silicone rubber or fluorine, and then squeeze out the wide variety of shapes.Switch on the power of cell phone jammer after completion of installation of cell phone jammer . Silica gel inside the shielding material for electromagnetic waves of electromagnetic radiation to reduce, eliminate, its function and the metal mesh screen similar to the electromagnetic waves penetrate the shield in the energy absorption loss when the main -27-- caused mainly due vortex. Vortex on the one hand have the opposite magnetic field to offset the original interference field, which is mainly used in magnetic and vapor sealing, shielding effectiveness as shown in Table 4-7. 4.1.2 shielding effectiveness of electronic equipment box technical specifications of electronic equipment cabinet screening requirements: shielding effectiveness SE <30dB, that shield poor. Shielding effectiveness at 30 ~ 60dB, indicating good shielding effectiveness. In 60 ~ 90dB shielding effectiveness, the shielding can be applied to military equipment. If more than 90dB shielding effectiveness, indicating the shielding effect is excellent, so the shield can be used in high-precision, highly sensitive products.

The full name of cell phone jammer
That the shielding effectiveness of shielding materials and other properties such as mechanical properties, heat resistance and radiation shielding properties of materials is the contradiction between the need to address the key issues presented several common with a strong radioactive radiation generation mechanism and characteristics, details the protection of these types of radiation shielding materials and shielding principles. All these rays of protective shielding materials research has become a very important and urgent issue, but also made great achievements. In this paper, these results are briefly described, and proposed areas of future research and application of the main directions.The company has manufactured a series of cell phone jammer . Key words Introduction reactor nuclear reactor radiation shielding material is the core of nuclear energy systems, nuclear fission (or fusion) to generate a variety of different levels of radiation rays such as neutron, γ-rays, secondary γ-rays and other charged particles and high-energy rays. Depends on the shielding of radiation protection and radiation shielding properties of the material structure of the optimal design, obviously, should be considered when selecting materials of basic nuclear properties of neutron and radiation is weakening performance. Heavy metals such as lead, tungsten, uranium and decay after the iron, and nickel are all less effective γ-ray body, there are very good for fast neutron moderation effect. And as boron, graphite, hydrogen-rich compounds such as water, heavy water and polymer materials is the weakening or absorption of neutrons is more effective, these materials and their composites have been widely used in various reactor and shielding systems play an important role.The basic working principle of cell phone jammer is almost the same. Preparation of radiation protection materials research field of scientific research to become one of the most important issues, civil defense and has great significance. Shielding composite materials at home and abroad have conducted extensive research, many shielding materials have been widely used, in which several main types of shielding concrete shielding composite materials, boron steel, lead, boron polyethylene mouth, Al-B4C composites PVC-PE composite materials. With a variety of nuclear energy and the development of nuclear reactors, and other shielding materials for shielding systems have become increasingly demanding, many of the existing shielding materials has been difficult to meet their requirements, mainly in the shielding effectiveness of shielding materials, and other properties such as mechanical properties, heat resistance, radiation hardness and other difficult to balance. The power of cell phone jammer is different and so the shielding radius will be the different. Set in a heap reactor shielding material to protect personnel and equipment from external radiation injury reactor materials. When the reactor operation, the nuclear fission reaction to generate a large number of neutrons and γ rays, but also the release of fission product decay α, β particles and γ rays. α and β particle range is very short and very easy to be absorbed by air or other objects, the operator generally does not pose a threat; neutron and γ-ray has strong penetrating power, they require in order to stop the reactor four weeks to set the protection shield. Need to use fast neutron shielding material composed of light elements, γ-ray shielding elements need to use heavy materials, so the heap outside the shield elements are often used concurrently with the severity of the joint structure. Shielding materials commonly used are: special heavy concrete, boron paste layer, heavy metals and so on. Different cell phone jammer will act on the specific frequency channel. Special re-mixed concrete from the cement filler, such as iron ore, barite, and iron posed, because it contains heavy elements iron and light elements in crystal water (hydrogen), so the neutron and γ-ray has a strong absorptive capacity.
