cell phone jammer company owns an authoritative R&D team



Is a brief piercing the shield cable are two possibilities: 1. Will lead shielding, which is equivalent to the shield extends to the wire ends. 2 pairs of wires be filtered, filter out high frequency components on the wire. Shielding process: installing the cable port on the low-pass filter can effectively filter out the interference on the cable to maintain the integrity of the shield. However, the premise is transmitted on the cable to protect the signal frequency and interference frequency far behind.
Normally cell phone jammer in the area 200m beyond the base station plays best.How to choose the screen mode with the current rapid development of information transmission technology, cabling system transmission rate in steady speed, it also brings a certain vulnerability of anti-interference, it is because the higher the frequency of information transmission, the signal sensitivity increase, while less and less of their energy, at this time more susceptible to interference cabling system. everywhere in the cable and equipment interfere with other components would interfere with or seriously interfere with other sources of interference, such as: computer screens, motors, mobile phones, radio broadcasting equipment, data transmission and power cables, etc. Once you turn the MDPB-02 mobile phone jammer on, it would work immediately.potential eavesdroppers, hackers and cyber crime increasing, because they block UTP cable transmission of information will cause huge damage and loss even if no physical connection, interception of information transmitted over UTP cable is also very easy, the intruder only to have a wireless receiver, signal processing equipment and a portable machine to commit crimes. data block in a few centimeters to several hundred meters are likely to occur within , and in most cases, completely unable to monitor, especially when using high-speed data network, blocking a lot of information was significantly lower than the time required to intercept low-speed data transfer time required. data twisted pair of strands in the low frequency.Once you turn the MDPB-02 cell phone jammer on, it would start a nonstop and steady work. The following can be twisted on its own to resist foreign interference and crosstalk between the lines of, but at high frequencies (especially when the frequency exceeds 250MHz or more), twisted pair alone has been unable to achieve the purpose of interference, can only shield against outside interference. cable shield acts as a Faraday shield, interfering signals into the shield layer, but not into the conductor, so data can be trouble-free operation due to shielded cable ( STP) than non-shielded cable with a lower radiation distribution, thus preventing the network transmission was blocked. shielded network (shielded cables and components) can significantly reduce access to the surrounding environment may be able to intercept the electromagnetic radiation levels. Belden has developed a unique set of shielding methods to improve the cable against electromagnetic interference / radio frequency interference and ensure signal integrity for data, audio and video to provide a guarantee for the smooth transmission and avoid downtime.What’s the main technical index of MDPB-02 cell phone jammer? For special interference problems, Belden can be designed and manufactured in accordance with requirements of shielded cable program. different interference field of the main screen select the interference field electromagnetic interference and radio frequency interference are two kinds of electromagnetic interference (EMI) is mainly low-frequency interference, motors, fluorescent and power lines are often sources of electromagnetic interference.
radio frequency interference (RFI) is a radio frequency interference, mainly high-frequency interference radio, television, radar and other wireless communications are often the source of RF interference for resistance to electromagnetic interference, select Braid the most effective, because of its low critical resistance; and for radio frequency interference.
