Case Study: AT&T achieves energy-efficient 5G network gains with Ericsson

AT&T and Ericsson: High-performing, efficient networks

The customer AT&T faced the challenge of modernizing its network infrastructure to meet rapidly rising data demands while also controlling soaring energy costs and reducing its environmental impact. To address this, they collaborated with the vendor Ericsson on a comprehensive modernization initiative involving Open RAN, Cloud RAN technology, and advanced software.

Ericsson implemented a solution using its advanced radio platforms and AI-powered software features like Micro Sleep TX. This resulted in a network that could handle nearly double the traffic while achieving up to a 20% annual gain in energy efficiency. The measurable impacts included annual savings of $28 million and a reduction of 22,963 metric tons in carbon emissions.
