Definition: continuous set of frequencies lying between two specified limiting frequencies

NOTE 1 – A frequency band is characterized by two values which define its position in the frequency spectrum, for instance its lower and upper limiting frequencies, as opposed to the bandwidth which is characterized by one value.

NOTE 2 – The nomenclature of the frequency and wavelength bands used in telecommunications are given in Table I and its Notes a, b, c and d.

NOTE 3 – Certain frequency ranges are sometimes designated by letter symbols consisting of capital letters which may be accompanied by a small letter as subscript. These symbols do not designate well defined bands, but are used by some radiocommunication services to designate the frequency bands allocated to them which are approximately located in the corresponding ranges. Table II gives for information the nominal limits of the ranges and the usual bands for radar and space radiocommunications. Reference should be made to the corresponding band limits, which may be approximate, or at least to a nominal frequency in the band, the first time the symbol appears in a text.
