LWBroadcastanteil

LWBroadcastanteil is a term used in German-speaking broadcasting and telecommunications literature to describe the portion of a transmission that is allocated to the long‑wave (LW) part of a multi‑band service. In essence, it denotes how much of a transmitter’s output or a network’s radiated power is devoted to the long‑wave frequency range versus other bands.

Calculation and measurement typically define the LW share as the ratio of long‑wave radiated power to the total radiated power: LWBroadcastanteil = P_LW / P_total, often expressed as a percentage. This can be determined from transmitter and antenna system data, or empirically from field strength or power measurements across the LW band. When multiple transmission paths or antennas serve the LW band, the share may be attributed to each path according to its contribution to the LW output. The exact frequency range considered “LW” depends on regional allocations but generally covers low-frequency bands below roughly 300 kHz.

Context and use: The LW share is used in engineering planning, spectrum management, and regulatory reporting to quantify how much capacity a facility allocates to long‑wave service. It informs load balancing, interference analysis, and licensing decisions for facilities operating in more than one band. The concept helps compare different transmission designs and assess compliance with coverage and power‑allocation requirements.

Notes: The LWBroadcastanteil can vary with time, frequency, and operating conditions due to changes in antenna matching, propagation, and system configuration. The term appears primarily in German‑language technical materials and may not be part of universal international standards.
