Legal Signal blocker Jamming

A legitimate signal occupies a legitimate frequency, and because the signal jammer power is too strong, the adjacent frequency band receiving equipment is blocked. For example, the common CDMA downlink frequency band interferes with the GSM uplink frequency band. The spectrum of this interference signal is uncertain, one after another, and it is generally an EMI problem.

The interference source with fixed odds works in the mobile communication frequency band. The interference frequency is almost unchanged, or there is a small range of jitter, and both uplink and downlink may exist. Such interference is more common in legacy dedicated radio systems occupying mobile resources. For example, the original power microwave communication system occupies the mobile 1800MHz frequency band. Since the interference source is a dedicated communication system, the interference signal is stable.
