cell phone jammer was made with advanced capability

Cable length also affect where and how to ground the cable as a major factor. Impedance of the circuit: the circuit impedance circuit means that there are low-impedance high-current work, while the high current itself will produce a strong magnetic field (higher inductance); high-impedance circuit means there is little current work, a small current itself will generate a strong electric field (higher capacitance).   cell phone jammer was made with advanced capability. Circuit impedance is chosen shielding material impact as a major factor. External electromagnetic interference: external electromagnetic interference: cabling networks that exist within the building power distribution box and distribution network, the high frequency interference, high-power electric motor electric spark generated by harmonic interference, fluorescent tubes, electronic starter, power switch, telephone network the ring current, information processing equipment and other interference generated by periodic pulse source, can not maintain a safe interval should be shielded system.   china cell phone jammer was born with brilliant maintenance. Network cabling outside the building there are radar, radio transmission equipment, mobile phone base stations, power lines, electric railways, lightning and other sources of interference area, if the environment at a high intensity electromagnetic field shielding system should be used. Ambient field strength or interference signal cabling system noise level exceeds the following requirements should be shielded as much as possible the system: a, when the introduction of computer local area network 10kHZ ~ 600MHz interference signal, the field strength of 1V / m; into 600 ~ 800MHz interference signal, the field strength of 5V / m; The company tries best to develop better   cell phone jammer   to provide advanced technology, excellent product, and perfect technical support and service.b, when the telecommunications terminal equipment via the signal line, such as the introduction of DC or AC line, the introduction of RF 0.15 ~ 80MHz interference signal, the field strength of 3V / m, interference on the digital signal modulation amplitude becomes 80% of rated, rated frequency range affected by the noise over ± 1kHZ; c, while with analog / digital terminal interface terminal equipment to provide telephone services, the noise level exceeds-40dBm transmission frequency band case while the sum is less than 200MHz; d, when the terminal equipment interface to services provided by the acoustic noise level exceeds the reference level, while the total interface bandwidth is less than 200MHz. The company is always positively searching new and advanced technology of   cell phone jammer  .External electromagnetic interference and electromagnetic interference are mainly two kinds of RF interference. Electromagnetic interference (EMI) is mainly low-frequency interference, motors, fluorescent lights 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 sources of RF interference. For resistance to electromagnetic interference, select the most effective shield braid, because of its low critical resistance; and for radio frequency interference, the most effective foil shielding, braided shield depends on the wavelength due to changes in the gap makes it generate high-frequency signal free access to the conductor.   cell phone jammer  can be fastened on the wall or ceiling directly with screw. As for the interference of mixing high and low frequency field, will have to use a broadband overlay layer of foil plus braid shield combination of methods: braided shielding for low-frequency range, and foil shielding for high frequency range.
