A radio spectrum is typically, the primary subject of spectrum
licensing and as such, it does help to have a background knowledge
of what a radio spectrum. In simple terms, a radio spectrum is a
collective term for all electromagnetic wave frequencies that
are useful for wireless communication. Radio waves are
invisible and undetectable to human sense but lie at the heart of
modern communications technology. Radio transmission technology
involves electromagnetic waves radiating outwards from one radio
equipment to another radio equipment, through the air
and travels as a wave of varying frequency, measured in hertz
(Hz). Electromagnetic waves, travelling through the air, are
transmitted at different frequencies depending on the electrical
signal applied to the transmitting equipment. Generally, frequency
and power determine transmission range, such that the lower the
frequency and the higher the power, the larger the transmission
range. Although high frequencies have
