  • Does the jammer block other electronic device signals?

    There are also cell phone jammer that can interfere with a wide range of frequencies. However, this type of jammer can choose to turn on or off a single frequency. So, in general, the jammer does not interfere with other frequencies.

  • Can jammers be used at extreme temperatures?

    For purposes of use, cell phone jammer is rarely used in extreme environments. Therefore, the use of extreme environments is not considered in the design. Usually the jammer can work in an environment from -10℃ to 50℃. If the temperature is too low, the jammer may need to be warmed up for a period of time to work properly. If the temperature is too high, prolonged use may cause damage to the jammer.

  • What's the difference between GSM and CDMA?

    CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are shorthand for the two major radio systems used in cell phones. The two cellular standards function in different regions and allow for global communication between individuals, and each converts incoming and outgoing data into radio waves differently.

  • What is frequency band?

    A frequency band is an interval in the frequency domain, delimited by a lower frequency and an upper frequency. The term may refer to a radio band or an interval of some other spectrum. Frequency band is an important standard for cell phone jammer The frequency range is different, the signal that can disturb is different.

  • What is MHz mean?

    The megahertz, abbreviated MHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one million hertz (1,000,000 Hz). MHz is a common unit of signal frequency used to distinguish different frequencies.

  • What is jammers?

    To put it simply, a cell phone jammer is, fundamentally, a signal blocking device, which transmits synchronized radio waves on the same frequency range of the device that one needs to blur, therefore preventing devices from transmitting data in the chosen area.
