C-Band Alliance Proposes to Clear 300 MHz for 5G
The C-Band Alliance (CBA) revealed that it will commit to clear 300 Megahertz (MHz) of C-band spectrum to support fast 5G wireless deployment throughout the continental U.S. In an updated filing with the U.S. Federal Communications Commission (FCC), the CBA detailed that the 300 MHz of spectrum includes a 20-MHz guard band to protect existing satellite services from 5G interference.
Further enhancing its plan to clear spectrum quickly, the first portion — which clears spectrum within 18 months of an FCC order in 46 top metropolitan zones — is now increased to 120 MHz, inclusive of the 20-MHz guard band. The second portion of the remaining spectrum will be made available within 36 months from a CBA-led auction, providing cleared spectrum throughout the entire continental U.S.
As it completed the work necessary to enhance its proposal, the CBA collaborated closely with U.S. broadcasters and programmers that serve nearly 120 million American homes via the C-band. This work included analyzing the potential use by some customers of technologies such as advanced modulation, single format transport and advanced video compression, including High Efficiency Video Coding (HEVC). Each of these technologies improves the efficiency of satellite video delivery, allowing the same video content to be transmitted over less spectrum. The CBA proposal commits to implement these technology upgrades at no cost to those satellite customers implementing them.
