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.
Read moreWhat is the best frequency for long distance?
The 7000 kHz (7 MHz or 40 metre) band is useful for daytime communication up to a distance of 800 km via E and F layers. Long distance world-wide communication takes place in this band through F2 layer.

Read moreWhat are high frequency waves called?
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 uses super high frequency?
Super High Frequency (SHF): 3-30 GHz Given their ability to carry enormous amounts of data, super high frequency waves are used for relaying broadcast programs (STL/TSL/TTL), radar (weather, etc.), satellite communications and satellite broadcasting, and other applications .
Read moreWhich wave has highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Read moreWhat is considered low frequency noise?
Abstract. Low frequency noise, the frequency range from about 10 Hz to 200 Hz , has been recognised as a special environmental noise problem, particularly to sensitive people in their homes.
