It’s no secret we’ve made impressive strides on our Open RAN journey to transition from closed, proprietary network architectures to fully open and programmable networks – a move designed to unlock speed, flexibility, and greater choice.
In August, we announced the successful completion of the first Open RAN call using third-party radios at the AT&T Labs in collaboration with Ericsson and 1Finity.
And now? We’ve quickly achieved another major milestone with these companies by completing the first Open RAN call using third-party radios over AT&T’s commercial network. This multivendor solution demonstrates the interoperability and flexibility Open RAN brings to our network, underscoring the critical role of collaboration in developing open and programmable networks that can transform the industry.
“Open RAN is more than a technology shift – it’s a catalyst for innovation and collaboration across the industry. By proving multivendor interoperability on AT&T’s commercial network, we’re not just advancing technology – we’re shaping an ecosystem that will accelerate innovation for our customers and the entire industry,” said Patrik Eriksson, vice president and head of the Mobile System Business Unit at 1Finity.
“This is a significant milestone for the industrialization of Open RAN, with the 1Finity radio operating with fully commercialized Ericsson software in the AT&T Network. The 1Finity radios are integrated into Ericsson’s Intelligent Automation Platform, its Open RAN management and automation platform, which enables multi-vendor radio support. It is a great proof point for Open RAN ecosystem collaboration,” said Paul Challoner, vice president and chief technology officer, Customer Unit AT&T, Ericsson.
Since announcing our plan to modernize our wireless network, we've made significant progress. To date, we've already completed nearly 40% of our overall swap program from Nokia radios to Ericsson. Additionally, we've added valuable mid-band (N77) spectrum to over 15,000 sites which deliver increased speeds and a greatly improved wireless experience for our customers. This accomplishment is a testament to the hard work and dedication of our teams. And this achievement isn't just a technical milestone – it’s a clear signal that the future of wireless will be open, agile, and innovation-driven.
