AT&T selects Ericsson for 5G and C-band expansion
C-band spectrum is critical for the deployment of 5G in the U.S. and new architecture will support future network enhancements including Centralized RAN evolving to Cloud RAN.

Building on more than 20 years of collaboration, Ericsson and AT&T have announced a five-year agreement to accelerate the expansion of AT&T 5G. This deal helps support deployment of the service provider's recently acquired C-band spectrum and the launch of 5G Standalone (SA) as well as future enancements such as Cloud RAN. Ericsson will help AT&T to bring its 5G network to more consumers, businesses and first responders across key industries — including 5G use cases in sports and venues, entertainment, travel and transportation, business transformation and public safety.

AT&T's network evolution is made possible in part by the Ericsson Radio System portfolio, which includes the Advanced Antenna System, Advanced RAN Coordination and Carrier Aggregation technologies. These deployments will support future network enhancements like Cloud RAN, which offers communications services providers increased flexibility, faster delivery of services and greater scalability in networks. The solution supports a centralized RAN architecture enabled by Ericsson Fronthaul Gateway, a new technology that will enable a more efficient transport of the fronthaul interface by converting it to packet (eCPRI).

Scott Mair, President, AT&T Network Engineering and Operations, says: "As we continue to expand our nationwide 5G network, Ericsson's technology offerings and 5G expertise will assist with our network evolution. This latest agreement provides the pathway for us to deploy Ericsson's next-generation centralized RAN architecture, enabled by Fronthaul Gateway, with the ability to support future network enhancements, like the evolution to Cloud RAN."
