The battery of this kind of good cell phone jammer

Posted by Unknown Friday, January 10, 2014 0 comments
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.

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.

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.

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!
