Does the jammer block other electronic device signals?
Because the signals have different frequency bands, the single-band jammer does not interfere with other frequency bands. Just as a jammer that can only interfere with a 3G signal can't block a 4G signal.
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.
