Radio regulatory aspects of frequency sharing

The requirement for communications, civil and military, analogue and digital, continues to expand and advances in technology have facilitated the expansion. Although much of the demand for data transmission in connection with information technology may be met by the provision of cable and optical fiber links, the pressure for expansion of radio communication continues. Some of the regulatory aspects of the use of the radio frequency spectrum are discussed and one or two of the problems associated with frequency re-use are highlighted.
