Radiobereichs

Radiobereichs is the German term used to describe radio ranges or radio bands within the electromagnetic spectrum that are allocated for wireless communication and broadcasting. In common usage, radiobereichs are divided into standard frequency bands, each with typical applications and propagation characteristics. The exact boundaries between bands can vary by country and by regulatory context.

Common bands include VLF (roughly 3–30 kHz), LF (30–300 kHz), MF (300 kHz–3 MHz), HF (3–30 MHz), VHF (30–300 MHz), UHF (300 MHz–3 GHz), SHF (3–30 GHz), and EHF (30–300 GHz). Lower-frequency bands tend to propagate over long distances and reflect off the ionosphere, while higher-frequency bands support higher data rates but require more line-of-sight or satellite links. Each radiobereich is used for different services, from long-range maritime and navigation signals to broadcast radio, television, cellular networks, Wi‑Fi, satellite communications, radar, and scientific experiments.

Regulation and management: The International Telecommunication Union (ITU) coordinates global spectrum allocations, and national regulators grant licenses, set usage rules, and manage interference. Frequency allocations are periodically updated to accommodate new technologies and services, often via regional agreements and auctions.

In practice, the concept of radiobereichs underpins the design of communication systems, allowing engineers to select suitable bands for coverage, data rate, and resilience to interference. Ongoing developments in spectrum sharing and dynamic allocation continue to reshape how radiobereichs are used.
