Störaussendungen

Störaussendungen, often translated as spurious emissions or unwanted emissions, refer to radio frequency energy that is present at frequencies other than the intended transmission frequency. These emissions can originate from a wide range of electronic devices, including radio transmitters, digital devices, and even household appliances. While some level of spurious emissions is unavoidable in electronic systems, excessive or poorly controlled levels can cause significant problems.

The primary concern with störaussendungen is their potential to interfere with other radio services. This interference can disrupt legitimate communications, leading to degraded performance, dropped calls, or complete signal loss. For example, a strong störaussendung from one device could drown out a weaker, intended signal from another, causing chaos in licensed radio spectrum.

Regulatory bodies worldwide, such as the Federal Communications Commission (FCC) in the United States and the International Telecommunication Union (ITU), set limits on the permissible levels of störaussendungen. Manufacturers are required to ensure their products comply with these regulations to minimize interference. Compliance is typically achieved through careful circuit design, filtering, and shielding of electronic components. Testing and certification processes are in place to verify that devices meet these standards before they can be sold. Understanding and controlling störaussendungen is crucial for the efficient and harmonious use of the radio frequency spectrum.
