Cell phone signal jammers effective range (30-40 m) generally refers to the indoor range. In the open area outside, shielding the effective distance of up to several hundred meters. It should be noted, both in indoor or outdoor use, the effective distance jammers and there was a certain relationship between environmental conditions, such as the distance from the base station, and locations and so on. Therefore, the use of cell phone jammers should take full account of this factor, to avoid dead ends and thus affect the shielding effect of shielding. The effect of mobile phones the same? 6.5 mobile phone signal jammers for GSM and CDMA mobile phones, like the effect it? cell phone jammer is used for phenomena that some illegal students cheat in the various other examinations in the school and students use the cell phone to chat in the class. A: Good question. As CDMA phones GSM mobile phone anti-interference performance is far superior, so the cell phone signal jammers effective shield for the CDMA mobile phone GSM mobile phone is less than the distance, but the difference is not large, about 2-4 meters. But also drew users' attention is particularly important in some places, if necessary, to increase the venue should be the number of cell phone signal jammers to ensure that the shielding effect of CDMA mobile phones. 6.6 mobile phone signal jammers case after a period of hot work, work long hours will not damage the machine? Cell phone jammer case after a period of hot work, work long hours will not damage the machine? A: Thank you for your careful, this is a normal phenomenon. Design, we took advantage of brushed aluminum chassis of the thermal conductivity to aid heat dissipation. Which can guarantee long time stability. cell phone blocker still can be used in such serious locations as the party and government institutions, theaters and so on which need tranquility.Therefore, the case will not damage the machine hot.
Status of the basic theory of electromagnetic shielding: shielding the growing demand for an increasing number of interference sources and sensitive to the growing number of sources of interference devices and sensitive devices increasing miniaturization of devices and sensors to make the source very close. This allows shorter transmission path, increasing the chance of interference. Miniaturization of devices to increase their sensitivity to disturbance. Auto: Auto: phone, laptop computer and other equipment available everywhere, but not necessarily limited to the office as a controlled environment. It also brings compatibility problems. cell phone jammer can block the signals within the specific range. For example, many vehicles equipped with anti-lock control system including a large number of electronic circuits, including, if the car phone is not compatible with this control system, it will cause malfunction. Large scale integrated circuit chips lower supply voltage reduces the internal noise threshold, and their precise geometry of the lower level would be under the arc damage. They produce more faster synchronization sharp current pulse, which will bring broadband emission produced from the port problem. In general, high-speed digital circuits than analog circuit system to produce more interference. For data confidentiality requirements is an important shield market power. U.S. embassy in Moscow has been reported to reveal the information has been held in the former Soviet Union to steal the car (Chechnya, Summit), which is to receive the embassy through the electromagnetic energy produced by the device to achieve the same technology can also be used to capture passwords.The jamming radius range of cell phone jammer is dependent on signal strength of field working environment. Then attack bank computer system. Through the shield, the device can reduce the electromagnetic emissions, improve system security. Not to mention the military industry.Not to mention the military industry.

The shielding diameter of cell phone jammer is 20-120m
The purchase of licensed mobile phones, the box is a very important part. Parallel as with many JS users licensed to sell, but often three packs in the box and exposed his true certificate. Generally speaking, the box will be affixed with a label on the product type, date, place of origin, IM EI code and bar code labels, regardless of the line are parallel, there will be. Of course, the parallel is false profiteers. Line of label printing is fine, legible, and very rough forged label printing, font is very vague. Is the line of packaging boxes and other accessories in addition to manual, the cell phone will have three bags of evidence that this is for the protection of consumer interests and policies, parallel cell phoneis not. cell phone jammer can effectively block various cell cell phone signals and there will be no missed point.
Buy mobile phone, can generally be identified by the following method is the "new" machine: see attached screen, whether there is a lot of bubbles, the new machine's screen is very neat paste; depends on the battery contacts, whether there are more plans marks; machines, batteries, accessories, and other packaging, is being opened; check the cell phonelist in the game, to see whether the zero points; check cell phone book, SMS, etc., to see whether the air; check whether the dead pixel screen, usually by displaying black and white picture to check (by the way, do not display a hand to squeeze out once the LCD, dead pixels also appeared); if the cell phone supports memory expansion, you need to contact the card check whether have more scratches. Here is the inspection items and technical requirements of cell phone blocker.
If you buy NOKIA mobile phone, you can also enter in standby mode * # 92702689 # (for S40), the cell phone shows a lot of items, one of which is the life timer, this value can be judged by the use of mobile phones The cell phone number will be used as the time that the call time and change, so bought back when the cell phone this number will be very small or even zero. If you are purchasing SIEMENS mobile phone, the new machines generally have an initial configuration, if not the process, must have been used by others. Finally, add that, where the so-called "new" machine probably is not really a new machine. The person with the pacemaker implant is not allowed to use cell phone jammer.
Because there will always be broken down for maintenance after the motherboard and other components, but most of these things should make the best use of, after the renovation will play their effectiveness. Even the store, get your hands can not guarantee the machine is completely new machine. So, when the purchase of the need to balance mind, to the reputable stores to buy mobile phones generally do not have a problem, enjoy the three bags of natural to OK it. Licensed a number of quality and performance to be stable. NOKIA and Samsung because of the different, not so many parallel channels. So many sites are actually selling machine Hong Kong Bank and the European version of the water change, which "change Europe," the stability of the machine is not so satisfactory. The shielding diameter of cell phone jammer is 20-120m.
NOKIA many parts are common, renovation will be more convenient, the article compared to the Samsung in terms of a much larger, it is usually "European reform" is the problem again and again. So do not yield to the temptation to buy cheap no formal invoice, there is no guarantee of the machine together, and perhaps the day will soon come to regret. After all, mobile phones will go wrong, as if life were not the same without sick. It would appear, of course willing to buy mainland licensed, or there is a regular invoice line in Hong Kong. Recommend the Hong Kong Bank, one is cheap, there is that you can with the regular invoice line in mainland China to Hong Kong warranty. Actually, a lot of selling line of business in Hong Kong, where he still ask you to repair, Well, a lot of things are self-evident, to see their own judgments slightly. cell phone jammercan ensure the security of confidential information of the meeting.
Buy mobile phone, can generally be identified by the following method is the "new" machine: see attached screen, whether there is a lot of bubbles, the new machine's screen is very neat paste; depends on the battery contacts, whether there are more plans marks; machines, batteries, accessories, and other packaging, is being opened; check the cell phonelist in the game, to see whether the zero points; check cell phone book, SMS, etc., to see whether the air; check whether the dead pixel screen, usually by displaying black and white picture to check (by the way, do not display a hand to squeeze out once the LCD, dead pixels also appeared); if the cell phone supports memory expansion, you need to contact the card check whether have more scratches.
