At&t accelerates open ran rollout, paving way for faster networks

AT&T is doubling down on its Open RAN strategy, aiming to deliver faster and more adaptable wirelessnetworks. The company’s progress, outlined by VP of RAN Technology Rob Soni, signals a significant shift away from traditional, vendor-locked cellular infrastructure.

Over 50% of at&t’s network traffic now flows through open-capable hardware.

Soni revealed that over half of AT&T’s network traffic is currently traversing hardware designed for open RAN architectures. This move represents a substantial step towards a more flexible and competitive network ecosystem. The company has successfully completed a live Open RAN call using Ericsson basebands and 1Finity radios, and is the first global CSP to deploy a third-party rApp to optimize its live production network.

The shift towards Open RAN isn't just about flexibility; it's about driving innovation and potentially reducing costs. Traditional RAN systems, often built around proprietary equipment from vendors like Ericsson, Nokia, and Huawei, can be rigid and expensive to upgrade. Open RAN allows for a modular approach, where radio equipment, baseband processing, and software applications can be sourced from different vendors.

Beyond hardware upgrades, AT&T is investing in the software layer required to manage this programmable network. The rollout of Ericsson's Intelligent Automation Platform, including the RAN Intelligent Controller, enables software-driven network optimization. This allows for faster updates and automation, ultimately benefiting subscribers through improved speed and reliability.

AT&T has already deployed Cloud RAN in two cities and anticipates scaling this Technology by the end of the first quarter. This moves network processing from centralized hardware at cell towers to data centers, further enhancing flexibility and enabling AI-driven performance improvements. The company's commitment to this transformation suggests a tangible improvement in network performance for users.

The upgrades are not just incremental; they represent a fundamental reimagining of network architecture. The company’s focus on software orchestration and automation indicates a proactive approach to meeting the ever-increasing demands of data-intensive applications. This isn't just about faster downloads; it's about enabling new services and capabilities.

The implications extend beyond AT&T. This move could accelerate the broader adoption of Open RAN, putting pressure on established vendors to innovate and compete on open standards. The long-term effect? A more dynamic and responsive mobile network landscape.

AT&T's current network experience hasn't radically changed in the past year, but the groundwork laid now promises a noticeable evolution in the coming months, signaling a decisive shift towards a more agile and future-proof infrastructure.
