During WRC15, ESOA members are engaging ITU Member States on Agenda Item 1.1 on C-band to secure a position of No Change and on Agenda Item 10 on future spectrum for IMT/5G to protect the satellite Ka-band and urge a decision above 31.8 GHz.

Reasons for NO CHANGE on C-band

  • Mobile network operators cannot provide emergency services that rely on C-band for life-saving communications
  • The global supply chain is enabled by ships at sea – their feeder links all rely on C-band
  • Hundreds of millions of people worldwide depend on C-band for broadcasting news, sports and entertainment
  • Mobile operators cannot provide aviation safety that is enabled by C-band
  • Satellite enables a host of services for the developing world where C-band provides the most reliable signal
  • Mobile network operators overestimate their spectrum needs
  • Mobile network operators exaggerate the value of C-band for IMT
  • Mobile network operators only use some spectrum already licensed to them

Reasons for identifying spectrum above 31GHz for 5G/ IMT for WRC19

  • The band 31.8-33 GHz has the greatest global support based on regional positions prepared before WRC15
  • Below 31GHz numerous satellite bands provide low-cost broadband, cellular backhaul, oil and gas, defence capabilities and a host of other services
  • 5G is new technology working hand in hand with existing technology; in order to be ubiquitous and resilient, satellite will be an essential component 
  • Over $100 billion US has been invested in existing and planned Ka-band satellite systems that have been, are being and will be launched from now until 2025 - these include GSO, NGSO, government and military satellite systems

Take the WRC15 Satellite Challenge


Some parts of the electromagnetic spectrum are particularly suited to meet the communication needs of specific countries and regions. This is particularly true for countries near or within tropical or equatorial regions that suffer from heavy rainfall such as Africa, Latin America and parts of Asia. Satellite signals transmitted in the C Band are more resilient to this rain fade - this means that strong rainfall does not easily interfere with the signals in this band. The C band also allows satellite networks to cover large regions, in a way that cannot be achieved with the same reliability, in other satellite spectrum bands.

C band links are used for applications that demand high reliability and a high quality of service such as backhaul for mobile telephony, TV distribution to local TV stations and cable systems, oil and gas, maritime, aviation, meteorology, health, humanitarian programs, government services, banking and health care. Many of these services can only be enabled in the C band. The African air navigation safety organisation ASECNA, for instance uses C-Band satellite earth stations based in Las Palmas as a communications infrastructure node.

Today more than 180 satellites with a C-Band spectrum operate in the world.
