Around the world, the C-Band is seen by the mobile community as a hugely important frequency for 5G. It is also intensively used for other services however – particularly in tropical areas, where its high resistance to rain fade makes it crucial for satellite services. The 3.4GHz – 3.6GHz portion of the C-band has been allocated on a primary basis to the mobile service and identified for IMT on a global level. However, the future of the 3.3GHz – 3.4GHz and the 3.6GHz – 3.8 GHz portions of the band in Regions 1 and 2 are set to be discussed in detail at WRC-23.

At WRC-23, the 3.6 – 3.8 GHz upper portion of the C-band is due to be studied ahead of a possible upgrade to co-primary for mobile in Region 1, and also for possible use for IMT 5G in Region 2. The 3.3 – 3.4 GHz portion of the band is due to be studied ahead of a possible identification for IMT in Regions 1 and 2.
