AM, which stands for Amplitude Modulation (AM) is the oldest radio broadcasting system in the UK. The term AM is commonly used to cover both Medium Wave (MW) and Long Wave (LW). All AM radio stations broadcast in mono.
Read moreWhat is MW on a radio?
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band.
Read moreWhat frequency range is the high frequency band?
High frequency (HF) is the ITU-designated range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz . It is also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres).
Read moreWhat is the frequency range of VHF and UHF?
In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.”
Read moreWhich wave is better for long distance communication?
Sky waves are radio waves reflected by the ionosphere. Therefore, the propagation of these waves is not limited by the curvature of earth. So, these can be used for beyond the horizon communication. Thus, sky waves are used for communication over long (inter-continental) distances.
Read moreWhat is S band radar good for?
The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites , especially those used by NASA to communicate with the Space Shuttle and the International Space Station.
Read moreWhat is the best frequency to use for communication?
There are two types of frequencies: VHF and UHF. VHF is the most suitable for businesses that must communicate across long distances . UHFprovides high yet short wavelengths, best for communicating within smaller spaces and metallic buildings.
