Trägerfrequenzen

Trägerfrequenzen, often translated as carrier frequencies, are specific frequencies within the electromagnetic spectrum used to transmit information. These frequencies act as a base or "carrier" wave onto which information signals, such as audio or data, are modulated. Modulation is the process of altering a property of the carrier wave, like its amplitude, frequency, or phase, in accordance with the information signal.

The use of carrier frequencies is fundamental to modern communication systems, including radio broadcasting, television, mobile telephony, and Wi-Fi. By employing distinct carrier frequencies for different transmissions, multiple signals can coexist and be transmitted simultaneously without interfering with each other. Each communication service or channel is assigned a specific carrier frequency range by regulatory bodies to ensure orderly spectrum usage.

The choice of carrier frequency depends on various factors, including the type of information being transmitted, the desired transmission range, and the available bandwidth. Lower frequencies generally travel farther and can penetrate obstacles better, making them suitable for long-distance broadcasting. Higher frequencies, on the other hand, can carry more information but have a shorter range and are more susceptible to atmospheric conditions. Understanding and managing carrier frequencies is crucial for the efficient and reliable operation of all wireless communication technologies.
