![]() walls, concrete), it is practical in built-up environments, indoors and within urban areas. UHF is a short-range communication frequency band that operates in the 300 MHz-3GHz bands, where radio waves are very compact, operate at higher frequencies, and have strong signal penetration, enabling UHF to communicate through obstacles (e.g. The frequency and wavelength differences between the UHF and VHF bands lead to the unique capabilities of these two types. MHz (or megahertz) is a unit of measurement used to measure radio waves, UHF (Ultra High Frequency) and VHF (Very High Frequency) represent the frequency types of radio transmit. A radio signal is a form of energy that moves in waves, just like sound waves. A radio operates by sending and receiving radio signals.
