Low or Medium Frequency – Definition
Low or medium frequency refers to a range of radio frequencies typically operating between 190 and 535 kHz. These frequencies are generally associated with nondirectional beacons, which transmit a continuous carrier signal that is modulated at either a 400 or 1,020 Hz rate.
These frequencies are used for various purposes such as navigation aids for aircraft and ships, as well as for long-range communication. They are also used in various scientific applications such as geophysics and atmospheric studies.
Low or medium frequency signals have the advantage of being able to travel longer distances than higher frequency signals, as they are less affected by atmospheric conditions and can more easily penetrate obstacles such as buildings and terrain. However, they are also more prone to interference and noise, and require larger antennas to transmit and receive the signals.
Despite their limitations and reduced popularity in recent years due to the advent of newer technologies, low or medium frequency signals remain an important component of modern communication systems and continue to be used in various applications across different industries.
