China NBT Mobile Phone Jammer System

Use high-tech eavesdropping can easily activate a certain mobile phone at a far distance to be eavesdropping tools. The scene andcontent of the talking will be easily intercepted by the opponent, leakage of a secret. In jails, the involved person through mobile phonecollude news and leak the details of a case, seriously affect the process of the case, endanger the social security. In many kinds of examinations, cheat by mobile phone is emerge in endlessly, influence the just and equitable of the examination. When mobile phone are working, it generates high intensity fadio-frequency radiation, poses a great threat to the safety of gas station, chemical depot, electric power dispatching room, always result the bombing events happened. Terrorist also make use of mobile phone detonate bomb, make terrorist attacks, seriously harm to life safety. In the precision instrument centralized places such as hospital clinics, wards and operating theaters, mobile phone radio waves will interfere over 90 percent medical instrument, affect instrument operation, result the needle vibrate and have noises, seriously will lead to measurement errors or damage the instrument, directly endanger the safety of the patient. In addition, in tender venues, memorial halls, museums, TV stations, studios, movie theaters, concerts, financial institutions, advanced hotel banqueting halls, Golf game sites, no loud noise public places and ATMB departments, mobile phone may become important factors that affect the process.

To structure a real applied jammer system, each jammer must be structured a controllable and manageable net to monitor shielding effectiveness. GSH mobile phone intelligent management system make use of power line carrier, integration of data stream transmission, detected fault-tolerant, noise treatment and anti-jamming technologies, make the best of power line channel, save resources and improve economic performance. Network structure as follows:

At the same time, GSH mobile phone intelligent management system have the features of remote control, no need of wiring, set shielding interval time as required, no need attend, intelligent operation etc.

The traditional mobile phone jammer are adopted radio interference technology, the working principle is transmit high power electromagnetic interference signal of the whole frequency band to suppress communication system signal, cut off the communication of mobile phone and base station. This method of interference is simple to operate. Although mobile phone jammer can block the communication of target mobile phone, its coverage is difficult to control, it always interfere with other “innocent” mobile phones, and the high power is harm to the health. The most seriously problem is that may interfere with the base station, so this equipment is prohibited by the operator and radio regulatory commission. GSH mobile phone jammer can set specified area and mobile phone, as small as 1 square meters range or numbers of mobile phones can achieve the effect, and it won’t interfere with the base station.

We pose a concept of mobile phone jammer, that is use specified electromagnetic signal structure a electric fence in the protected places, form a three-dimensional shielding region, make the mobile phone can’t receive the signal in the region, block the signal, eliminate the negative impact generated by the mobile phone. Due to only interfere with the specified downstream channel, GSH mobile phone jammer can’t interfere with the base station.

GSH mobile phone jammer is different with the general mobile phone jammer. For example, the following graph shows the GSM900M spectrum interference, GSH mobile phone jammer don’t interfere with up channel and other frequency band. GSH mobile phone jammer use modern high and new technology, it is the information security products that have our own knowledge of the sovereignty manufactured by depth analysis of connunication mechanism and comparison of electromagnetic emission suppression method. It forms a electromagnetic protection field around the installation place, can effectively prevent reveal the secret and eliminate noise pollution. GSH mobile phone jammer will offer you a safe and quiet space, become your reliable and loyal defender!

GSH mobile phone jammer have got the certificates issued by the State Secrets Bureau Information Security Product Testing centre, State Secrets Bureau Commission of Scientific Research Achievements identification, Electronic Product Quality Testing Center, Chinese People’s Liberation Army Information Security Assessment Center, State IECEX Quality Supervision Testing Center, State Secrets Bureau Electromagnetic Leakage Protection Product Testing Center, Security and Police Electronic Product of Ministry of Public Security Testing Center.

At the beginning of the last year, the policy to the special industry mobile phone jammer has standardized and conditional relaxation. State Secrets Bureau, Ministry of Information Industry Radio Regulatory Commission and Northern Jiaotong University worked out the first industry standard “Confidential meeting of the technical requirements and testing methods of mobile phone jammer”. With the relaxation of the policy, the expert shows that mobile phone jammer have a enormous market potential, industry development space is extremely vast. At present, the number of mobile phone ownership has achieved 20,000,000,000. It is estimated that the requirement of mobile phone jammer is 1% of the total number of mobile phone ownership, that is each 100 mobile phone user will correspond to a mobile phone jammer user, the user may be the safe places, privacy places, quiet places, public places or individuals.

Mobile phone jammer system can applied not only in armory, party, government and military, public security organs, finance, business secret etc. advanced places, but also the places close to people’s life. The expert believe that the mobile phone jammer market scale can reach several hundred billion yuan.
