UHFbereich

UHFBereich, or Ultra High Frequency band, refers to the portion of the radio spectrum typically defined as roughly 300 MHz to 3 GHz. This range is used worldwide for a variety of terrestrial communication services, but exact allocations are determined by national regulators in line with ITU guidance, so the subbands can differ by country.

In practice, the UHFBereich encompasses several significant applications. Terrestrial television broadcasting has historically relied on parts of the UHF spectrum (for example, DVB-T and DVB-T2 deployments in many regions). Mobile and wireless communications also use substantial portions of the band, particularly the sub-6 GHz range around 700 MHz up to about 2.6 GHz, which supports 4G and 5G services in many countries. Wireless networking and short-range communications, including Wi‑Fi and Bluetooth, frequently operate in the 2.4 GHz portion of the UHF band. Other uses include point-to-point microwave links, certain radar systems, and various professional and industrial communications.

Regulatory aspects of the UHFBereich involve spectrum allocation, licensing, and coordination to avoid interference between services. Some subbands are licensed, others are shared or available on an unlicensed/regulated basis, depending on national rules. The spectrum here has evolved with technology, with portions reallocated from broadcast to mobile broadband in some regions. Because allocations vary by jurisdiction, the exact frequencies and rules differ across countries.
