Spectrum Management and Coordination

Spectrum refers to the frequencies which are used by various radio-communication services.

IMDA regulations play a key role in the management and coordination of spectrum planning, allocation, and assignment due to the limited nature of the resource. This includes ensuring the efficient delivery of services such as mobile, fixed, satellite, short-range devices, and broadcasting. In addition, the provision of services will be handled by Spectrum Monitoring to analyse measurement results for better spectrum planning and to investigate on the interference cases.

Spectrum Monitoring

Spectrum Monitoring supports the overall spectrum management effort by providing a general measurement of channel and band usage, including spectrum occupancy coupled with inspection and compliance. Monitoring aids in the identification and measurement of spectrum usage, interference sources, the verification of proper technical and operational characteristics of radiated signals, and detection and identification of illegal transmitters. In conclusion, IMDA regulations on spectrum monitoring provide feed-forward information to spectrum management, thus producing data on the effectiveness of spectrum management policies.

For report on Radio Frequency Interference, please direct written email to spectrum_monitoring@imda.gov.sg.
