US telecommunications giant AT&T and Ericsson, a global leader in telecommunications technology, have achieved a significant milestone in the advancement of 5G technology. The successful completion of a cloud RAN (Radio Access Network) call marks a pivotal moment in the evolution of telecommunications infrastructure.
Cloud RAN Call Completion
The cloud RAN call, facilitated by Ericsson’s cutting-edge cloud technology, was conducted over AT&T’s commercial 5G network. This achievement demonstrates the seamless integration of cloud-based solutions with existing telecommunications networks, paving the way for enhanced performance and efficiency in 5G connectivity.
Commercial Traffic Flowing on Cloud RAN Sites
AT&T has confirmed that commercial traffic is now flowing on cloud RAN sites, with the first site located south of Dallas, Texas. This milestone signifies the operational readiness of cloud RAN infrastructure and highlights AT&T’s commitment to embracing innovative technologies to drive network evolution.
Accelerating Open RAN Deployment
Chris Sambar, Head of Network at AT&T, emphasized the significance of this achievement in the context of AT&T’s Open RAN journey. By migrating traffic to cloud RAN sites, AT&T is accelerating its C-Band deployment and advancing the virtualization of its network infrastructure. Sambar expressed optimism about the transformative potential of open network architectures in delivering enhanced experiences for customers.
Ericsson’s Role in AT&T’s Open RAN Initiative
In December 2023, Ericsson secured a landmark five-year contract worth $14 billion from AT&T to build the telco’s Open RAN network. This strategic partnership underscores Ericsson’s commitment to driving innovation in telecommunications infrastructure. With Ericsson’s expertise and technological prowess, AT&T aims to achieve significant milestones in its Open RAN deployment.
Future Outlook: Integration and Expansion
AT&T envisions a future where Open RAN platforms play a central role in its network architecture. The telco anticipates that 70 percent of its mobile network traffic will flow across Open RAN platforms by late 2026. From this year onward, AT&T plans to fully integrate Open RAN sites in collaboration with Ericsson and Fujitsu, leveraging the capabilities of multiple suppliers to drive network innovation.
Collaborative Efforts in Cloud RAN Migration
As part of the recent Cloud RAN initiative, AT&T and Ericsson have successfully migrated one frequency band, 3,700MHz, for their C-Band traffic to Cloud RAN infrastructure. This collaborative effort demonstrates the synergy between industry leaders in driving the adoption of cloud-based solutions for enhanced network performance and scalability.
Driving Innovation in 5G Connectivity
In conclusion, the completion of the cloud RAN call between AT&T and Ericsson represents a significant milestone in the advancement of 5G technology. As telecommunications operators continue to embrace cloud-based solutions and open network architectures, we can expect to see further innovation and expansion in 5G connectivity. With collaborative efforts and strategic partnerships, the future of telecommunications holds immense promise for delivering enhanced experiences and connectivity solutions to users worldwide.
