World Radiocommunication Conference 2015 (WRC-15)

The UMTS Forum at WRC-15

Taking place in Geneva from 2 to 27 November 2015, the World Radiocommunication Conference (WRC-15) is a key event for everyone with an interest in the global allocation and use of radio spectrum. WRC is held by Radiocommunication Sector of the ITU (ITU-R): the body that leads standards and spectrum arrangements for mobile broadband services - both today and tomorrow.

World Radiocommunication Conferences are held every three to four years. It's the remit of each WRC to review and, as necessary, revise regulations that govern the use of radio-frequency spectrum for communication and other purposes.

At WRC-15, the UMTS Forum is urging national administrations to adopt a holistic, forward-looking view of radio spectrum allocation for mobile broadband (MBB) systems. Read our press release summarising recommendations on specific WRC-15 agenda items.

Understanding the opportunities for C-Band

Decisions taken at WRC-15 have a considerable impact on the development of the mobile broadband market, and on the evolution of technology and networks.

As an input to the work of the ITU's Radiocommunication Study Groups, the UMTS Forum has conducted a major study on current usage and likely future demand for frequencies in the 3.4-4.2 GHz range. Widely known as the ‘C-Band', this tranche of spectrum is currently used for various radio communication services involving satellite, fixed, nomadic, mobile and radar systems.

As the study notes, the whole of the C-Band will play a critical in the future evolution of 4G/LTE and IMT-Advanced, as mobile traffic grows and currently-used frequency bands below 3GHz face congestion.

In order to understand and prepare for future worldwide spectrum usage for high peak data rate mobile broadband systems, the UMTS Forum has examined current allocation and usage of the C-Band in a sample of 40 countries across all ITU Regions.

The study's findings suggest that there is already a dynamic move in some countries that will try in the coming years to introduce IMT-Advanced in all or parts of the C-Band, subject to sharing arrangement with existing fixed satellite systems.
