Interruption to other equipment
It is known that the current phone signal is here and there, all electric equipment is surrounded by it . The surrounded phone signal can't almost interrupt other electric equipment when the phone is switched off, because the power off phone disconnects with the launching pad, no signal is produced, the electric equipment is surrounded by a relatively stable electro magnetic field -a static field, such a static field almost disinterrupt the equipment , while when the mobile phone is on, the phone connects with the launching pad, and signal is produced, a dynamic field surround the equipment, this dynamic electromagnetic signal may produce interrupting signals causing the equipment disorderly.
Undoubtedly fence shaped signal produced by the jammer is an electromagnetic signal, and this sort of signal never communicate, with other equipment, never makes suddenly changed signals. In other words, this signal is always static using the phone signal jammer will change the suddenly changed signals to net-actively static signal, therefore basically solve the phone's interruption to other electric equipment.
