The battery of this kind of good cell phone jammer is the durable type.
Hybrid satellite and terrestrial solutions to the countries covered by geostationary satellites in low-power repeater network and the mobile base station co-location, to provide urban and indoor coverage. The manufacturers argue that, if you do not use the S-band in the country coverage of the DVB-H in UHF is not economical because it requires a large number of transmitter and receiver. The market is still before the analog shutdown mode, the lack of available digital spectrum to support deployment of this technology, at the same time, the S-band frequency bands are available in any place. Manufacturers are expected to DVB-SH will commence in Europe for land the citys commercial, the end of 2007 to 2009, there will be a dedicated satellite to provide country-wide coverage. The product description of cell phone jammer should be as exact and accurate as possible.Several shielding positions of cell phone jammer locate at sides of hallway
A variety of software in the smart phone Forum, endless domestic mobile phone software applications has just started, users do not have a strong ability to identify, the results appeared in fish, wanton rampage rogue, front-end on the occurrence of an influential and destructive strong OPDA trays "incident, in the new software, especially the OPDA smart phone Forum, users claim that a famous foreign software crack, the results of the user under the computer all automatic grid, resulting in a lot of bad impact. On the computer, the rogue software on the phone more than is deducted user fees, get money for the purpose, so the worse nature, some commercial software is self-defeating. The customer should use and maintain cell phone jammer in the suitable manner.
User pull: In Japan, mobile payment wallet alternative is obvious. Buy virtual goods online supermarket shopping and spending, take the subway, take the bus, hospitals no longer need to queue up, the airport do not have to queue up for boarding passes, dinner singing and watching movies. Almost all of the daily consumption can be by a brush easy to get. In China, after years of gestation period, the user has the convenience of mobile payment is more recognition. The market potential is huge: CUP data show that the first half of 2009, Chinas mobile payment users exceeded 19.2 million, a transaction of 62,680,000 results, the amount to be paid a total of 17 billion yuan of transactions and transaction amount increased by 42% and 64% respectively than last year.
But will have on the wireless network in seconds, this speed is too slow to run a network game. Mobile operators strive to improve the mobile phones available bandwidth, network latency has not been satisfactorily resolved.

there are two kinds of antennas of Cell Phone Jammers available

The accurate shielding can be performed to this kind of  Cell Phone Jammers 
Master receive eight data loopback acknowledge bit, but directly back to your one stop signal to complete a read operation immediately; select the read mode, the master device first sends a start signal from the device address, and finally read data; continuous mode immediately read or choose to read the expansion immediately read or read operation to obtain a byte of data in the implementation of the master device and back to your stop signal but back your an acknowledge bit to indicate that the main device more data are needed, then an orderly manner from the device subsequent bytes of data sent to the data online, know so far received the master device is given the stop signal. In the SCM system, the CPU is not only to achieve control of their own.
If successful after the completion of the CPU from the external character to take the program execution, if made to the program exceptions, it can lead to "watchdog" to reset both the program and from address 0 begin. The CPU reads the character through the parallel data and address lines and address lines, together with the read and write control clock line W / R, some readers may ask, font is how to distinguish between the program read, or read the data? Microcontroller with external program memory chip select signal line or the CS, CE, and the W / R role, you can allow the character to distinguish between read data or program. Phone all the software work processes are carried out under the action of the CPU, the specific division of the five processes described below. This is one of reflects that the quality assurance of  Cell Phone Jammers is productive.
These processes are in the form of a software data storage in the phone EEPROM and FLASHROM of in the process boot process. When the phones power supply module detects a power key is pressed, the cell phone battery voltage is converted to a voltage value for each part of the mobile phone circuit supplied to the power module, the clock circuit supply voltage after oscillation signal into the logic circuit, CPU voltage and clock signal, performs the boot process, first of all read from the ROM boot code, the implementation of the logical system self-test. And all of the reset signal is set high, if the self-test by the CPU given Watchdog (Watchdog) signal to each module. From the S60 phone has launched, Nokia can be said to deliver the largest section of the manufacturers. The testing cares about the product quality of Cell Phone Jammers .And there are two kinds of antennas of Cell Phone Jammers available
Through the infrared interface, the various types of mobile devices can be free to exchange data. Infrared electromagnetic waves of wavelengths between 750nm to 1mm, its frequency is higher than the microwave lower than that of visible light, a human eye can not see the light. Due to the shorter wavelength of the infrared obstacle diffraction poor, so more suitable for application in situations that require short-range wireless communication, point-to-point straight-line data transmission. Infrared Data Association (IRDA) to limit the scope of the wavelength of light used by the infrared data communication within the 850nm to 900nm. Mobile phones equipped with infrared interface for wireless Internet is very simple, do not need cable and PC CARD set up an infrared connection agreement will be able to direct Internet access.

The aluminum alloy frame of cell phone jammer is adopted

Requestors are as many as cell phone jammer
Obviously, if we choose the conditions to determine if else, to judge the success of the conditions in the final else, we will unfortunately have to get to the data compared with all possible scenarios, a switch is the efficiency of many, will jumped into the branch we need this code is written in the run thread, that is, before closing the game will be an unlimited number of execution, we add a counter in the run thread, and then entered the game in figures do not move, in this case, the code will not enter the case branch, which is the optimal point in time when the first run to this location is 13.343 seconds, 101 runs to the time of the position point is 34.062 seconds. The aluminum alloy frame of cell phone jammer is adopted.
Similarly, we enter the game, to maintain the character does not move, that is, without any action, but this is probably the worst, the code will be detected from the first branch to the last branch, all the keys to match the detection side, If the characters move around will match from the middle position out of our characters do not move the case to record the implementation of the 1st to the point in time of 4.531 seconds, 101 times the execution time of 25.453 seconds, during which total consumption of 20.922 seconds for a total of 100 times, after the optimization of this process, the running time is reduced by 0.203 seconds. see that our optimization method is indeed to improve the effect of the code speed. Second, mobile phone game scale lack of technology, mobile games and there is no single industry standard, game developers to launch the game can only be run on a specific platform, which greatly diminished its market potential. cell phone jammer can act on CDMA, GSM, PHS, PCS, DCS and 3G.
Game mobile game service providers, but it is fragmented and have little effect, unlike the computer network games as can organize large-scale computer and video games, to cultivate a loyal group of professional players. In addition, the phone memory is also a constraint to the limited phone memory can meet the needs of todays most common games and other entertainment applications, but the face of the next generation of games have become the biggest obstacle. example, the phone can only save four games.

The material test of cell phone booster cannot be cancelled
Further established the worlds largest cell phone users status. Industrial scale, concentration increased as of April 2007, 41 new cell phone companies, including 11 foreign-invested enterprises, Chinese enterprises to 30, with production capacity of about 140 million while the new cell phone manufacturers in the low-end products based mainly on the Chinese market, the annual demand of about 60 million to 100 million units, made in China to exceed demand and production companies to expand the number of cell phone production growth will further exacerbate the market competition increasingly fierce competitive environment has led to an overall decline in industry profits, loss of business and the amount is increasing. cell phone booster can work continuously for a long time. On the other hand, the Chinese cell phone industry to further expand the industrial scale, while also further enhance the industrial concentration which Nokia, Motorola, Samsung, Sony Ericsson, Bird, Lenovo, and Amoi top ten companies account for almost the total production of all 80% of the industry, including Nokia, Motorola, Sony Ericsson and Samsung, the market share of 81.96 percent, the domestic cell phone market share of SMEs is very limited. 72. handset industry value chain structure of the cell phone industry value chain structure divided into three two components: the upper reaches of cell phone R & D, design and component suppliers, midstream and downstream cell phone handset manufacturers brand marketers, operators in the mobile industry on a technical level, Chinas cell phone industry is still in catch-up phase, the total production level in the cell phone Chinese cell phone industry in rapid growth stage. The company only takes responsibility of changing a new cell phone booster or repairing cell phone booster .
Chinese cell phone industry cluster is still in the global value chain under the low value-added chain. Handsets needed for the production of most of the active and passive, body parts (only about 30% of production costs) can be made, but not yet fully grasp the industry core technology and key components of the production technology, and small-scale enterprises, SMEs accounted for 92.61% of the proportion of overall competitiveness. Chinese cell phone industry structure shows structural characteristics of olive shape: the upper reaches of the lack of core technology and key components industry production technology; River is gradually assembled a strong, general parts production capacity; and downstream of brand management, logistics are still weak. Upstream: cell phone design platform (chip module). Overall, Chinas cell phone industry cluster is still in the low-value-added chain of production processes and generally supporting the production of parts gathering stage of development.

Build a Cell Phone Jammer Schematic Diagram
 
This cell phone jammer operates at GSM800 frequency since most mobile phones use it to operate. So the selected VCO is a sweeping oscillator, which is very effective but may be hard to construct for the beginners without nice RF-testing equipment.

As a noise source you can use 45MHz clock oscillator which is driving Local Oscillator port located on a mini-circuit mixer. There is also an impedance matching network for Local Oscillator signal to pass through it. It is used to equate impedances of the clock oscillator and the port of the mixer.

RF input (which is this port of the mixer) connected to the first 800MHz cell phone antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power for 15-16dbm. The amplified signal then sent to the second cell phone antenna.

 works
All cell phones which use GSM800 have their transmitted and received frequencies always separated by 45MHz. So when the mobile phone tries to call it is blocked by its own signal returning to it! Isn’t that cool? When the phone blabber annoys you – turn your jammer on and that wrongdoer will hear own voice in his or her cell phone.

Oh, by the way, you can also use this mobile signal jammer to block any cell-based tracking systems which use your GPS to track and record your car’s moves. And it is quite possible (though I didn’t actually tested it) to jam IEDs which detonated using cell phones.

The mixer used is designed to work up to 600MHz but in this case it works pretty well.

RF amplifier is doing its job perfectly yet (as it was mentioned in the Jammer Store blog post) draws additional power.Old aluminium box was used as a frame for the jammer and old UHF connectors from Motorola cell phone as input/output.You need to attach RF connectors to the circuit. Nine volt battery and voltage regulator were used to supply all components. The battery was placed inside and separated by the foamed plastic from the other components.The power on/off switch is placed on the top. The input and output antennas (also from old Motorola mobile phone) are screwed onto UHF connectors.Your cell phone jammer is ready. Enjoy!
