Because low frequency waves travel globally, they have practical uses. Long before GPS existed, engineers used low frequency waves broadcast from radio stations to determine location anywhere on the planet . And various navies have been using low frequency waves to communicate with submarines across an entire ocean.
Read moreWhat are low and medium frequency radio waves used for?
Frequencies immediately below MF are denoted low frequency (LF), while the first band of higher frequencies is known as high frequency (HF). MF is mostly used for AM radio broadcasting, navigational radio beacons, maritime ship-to-shore communication, and transoceanic air traffic control .
Read moreWhat are high frequency radio waves used for?
The main uses of the high frequency spectrum are: Military and governmental communication systems . Aviation air-to-ground communications. Amateur radio.
Read moreWhat is medium frequency?
Medium frequency (MF) is the ITU designation for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz) . … The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometer (1000 to 100 m).
Read moreWhat is HF frequency used for?
The band is used by international shortwave broadcasting stations (2.310 – 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services , among other uses.
Read moreWhy do we use higher frequency?
Increasing the frequencies will give everyone more “room” to transmit radiowaves . Increasing data rates, because having a higher carrier frequency also allows to widen the communication channel. Miniaturization (higher frequencies = lower wavelengths = smaller antennas and systems)
Read moreWhat is low frequency used for?
The Low Frequency (LF) band is mostly used for AM broadcasting in Europe as well as in areas of Northern Africa and Asia . Similar to VLF, LF can also be used for navigational radio beacons. It can also be used for maritime ship-to-shore communication, as well as transoceanic air traffic control.
