WRC-97), adopted at the World Radiocommunication Conference held in Depending on the frequency range, the radio spectrum is divided into frequency bands and sub-bands, as illustrated in Fig. 5 X 11; black/white) The document provides a chart summarizing radio frequency bandwidths and their allocated spectrum ranges. This chart provides a rough guide to typical RF band nomenclature in engineering. SHF Super-High Frequency 3-30 GHz EHF Extremely-High Frequency 30-300 GHz Each of these bands is divided into sub-bands which are allocated to particular services such as land mobile radio, broadcasting, aeronautical, maritime or space services — shown in the chart by different colours. For example, low-frequency (or simply LF), refered to any radio wave frequency with a corresponding wavelength between 100 m and 1 km. For example, broadcasting, mobile radio, or navigation devices, will be allocated in non-overlapping ranges of Frequency reconfigurable antenna for VHF two ways radio is designed. The chart also shows the frequency ranges in Hertz allocated to each band. (b) No station may transmit with a transmitter power exceeding 1.
