Blanket jam refers to a widespread disruption or interference in electronic communication or signals, often caused by excessive electromagnetic interference (EMI) or radio frequency interference (RFI). It is characterized by a situation where a large area experiences a significant decrease in the quality or complete loss of signal transmission, leading to disruption in various forms of communication.
The term "blanket" signifies the extensive coverage of the disruption, affecting a broad area rather than being limited to a specific location. It can include interruptions in various modes of communication, such as radio, television, cellular networks, internet connectivity, or any other technology that relies on wireless transmission.
Blanket jam can occur due to various reasons, including natural phenomena such as solar flares or electromagnetic storms, intentional interference by third parties using jamming devices, malfunctioning or equipment failure, or unintended interference caused by sources like power lines or other electronic devices emitting strong electromagnetic fields. This interference disrupts the proper functioning of antennas, receivers, transmitters, or any device involved in transmitting or receiving signals.
The consequences of a blanket jam can be significant, leading to communication breakdowns, loss of critical information, compromised public safety, disruptions in transportation systems, and economic losses. Efforts are made to mitigate blanket jams by implementing proper shielding measures, improving infrastructure, utilizing advanced technologies, and adhering to regulatory guidelines that aim to minimize electromagnetic interference.
