Radio Frequency Spectrum

The radio frequency spectrum is a finite natural resource with significant technical, economic, and social importance for every country. It is used to deliver a broad range of radiocommunication services, including:

  • Public and private mobile communications.
  • Satellite services.
  • Radio and television broadcasting.
  • Aviation and navigation,Maritime (Aviation, navigation and maritime) radio communications.
  • Public safety services.
  • Emergency response operations.
  • Radiolocation, and others.

The Telecommunications and Post Regulatory Authority, represented by the Spectrum Management Department, is responsible for managing all activities associated with this limited natural resource. These activities include spectrum planning, allocation, and licensing, as well as international coordination of terrestrial and satellite frequencies, network monitoring, and ensuring compliance with granted licenses. All these efforts aim to ensure optimal spectrum use, prevent harmful radio interference, and support high-quality telecommunications services that meet the needs and expectations of the public and all beneficiary sectors, now and in the future.

  • Planning frequency bands and allocating them to various radiocommunication services and applications.
  • Regulating radiocommunication services, systems, and wireless applications, and developing a national radio regulatory framework.
  • Managing the national spectrum plan and the strategy to ensure optimal usage.
  • Cooperating and coordinating with other national sectors that use the spectrum to ensure integrated efforts.
  • Implementing administrative and regulatory procedures for licensing frequency use across different radiocommunication services.
  • Offering frequency licenses through a transparent and fair competitive process.
  • Coordinating international frequency assignments for space and terrestrial services with local and international stakeholders.
  • Reviewing international regulations, agreements, and recommendations, and representing the country in relevant events.
  • Conducting radio monitoring and inspections to ensure efficient spectrum utilization nationwide.
  • Addressing complaints regarding harmful or electromagnetic interference to protect licensed uses.
  • Maintaining and managing the National Frequency Register, ensuring data confidentiality and updates based on radio monitoring.
  • Operating spectrum monitoring systems to ensure the safe and sustainable use of this limited resource

The World Radiocommunication Conference (WRC) is responsible for reviewing and updating the Radio Regulations issued by the International Telecommunication Union (ITU), as well as international treaties governing the use of the radio frequency spectrum and geostationary and non-geostationary satellite orbits. These reviews are conducted based on an agenda set by the ITU Council, with the WRC held every three to four years.

Radio frequency interference is a common issue that can impact the performance of many devices and systems, causing degraded signal quality, audio or visual distortion, or complete signal loss. Interference can interrupt or reduce the quality of wireless communications.


Procedures for Harmful Interference:

  • Licensees report any harmful interference affecting their networks by completing a specified interference form (link provided).
  • Licensees submit a report verifying that all internal checks were conducted to ensure the interference is not due to their own network configuration.
  • The interference form is submitted via the Authority’s official email.
  • The Wireless Network Monitoring Division performs field measurements for the affected spectrum and issues a report on the measurement results.

This table serves as the regulatory framework for making spectrum bands available for use. It details the allocation of various radiocommunication services across frequency bands ranging from 8.3 kHz to 3000 GHz. This table is periodically reviewed to incorporate technological advancements and updates in global radio regulations.
