What is the range of radio frequency spectrum?
The RF spectrum starts from 9 kilo hertz and the upper limit extends up to 3,000 GHz, beyond which the optical frequency starts. While, the spectrum may appear to be in abundance, practically it is extremely limited because of various reasons. There are certain technology equipment built to operate only over a certain range of spectrum and there are competing requirements for various applications. As of now, spectrum of up to 70 GHz can be used practically and technologies for utilising higher frequency bands are being developed. In what spheres of life do we find spectrum being used? There is hardly any sphere of life which does not use radio communication in one form or the other. Starting from public telecommunication services to maritime, aeronautical broadcasting, communications for defence, paramilitary, law and order agencies (police), transport, oil and electricity sectors, public utility services, health and environment – they all require spectrum. What is spectrum management?
