T-Mobile US is testing AI to allocate radio resources on its 5G-Advanced network, with Ericsson trial results showing the biggest gains during peak traffic.

The operator is trialling AI-Managed Beamforming on live commercial traffic at scale. Chief network officer Ankur Kapoor (pictured) outlined the results in a blog post. The work focuses on sounding reference signals (SRS), short transmissions from phones that help the network measure the path between a device and a cell site and direct beams more accurately.

Due to those resources being limited, they have traditionally been allocated under fixed rules. T-Mobile instead uses a supervised-learning model trained on its network data and running on Ericsson’s RAN compute and silicon to predict where demand is rising and redirect resources accordingly.

Kapoor explained training the model on T-Mobile’s data gives it an advantage on the operator’s network over networks which do not contribute their own tuning data.

The results came from newly activated sites in New York City, but the blog did not say how many were included or give a baseline for the trial.

T-Mobile reported the biggest gains during peak hours, including about a 50% increase in advanced beamforming using full-band SRS, a 16% improvement in downlink user throughput, 12% better spectral efficiency and a 10% increase in downlink data volume.

In May, the companies reported close to 10% better spectral efficiency from a separate AI-native scheduler with link adaptation on live traffic.

Kapoor said the technology suits T-Mobile’s network because beamforming works particularly well in TDD spectrum, where uplink and downlink share the same band, and the operator has a leading position in midband TDD.

He linked the trial to rising network demand, citing Ericsson’s June 2026 Mobility Report, which reported global mobile data traffic growth of 22% year-on-year. Video accounted for about 75% of traffic and 5G subscriptions topped 3.1 billion.

Jaco du Plooy, SVP and head of the T-Mobile customer unit at Ericsson Americas, stated the trial marked another step toward networks which respond more intelligently to demand, enabled by Ericsson’s silicon.

Kapoor said 6G networks will need to sense, learn and respond to support applications such as distributed AI, robotics, vision AI and other forms of physical AI, describing T-Mobile’s nationwide 5G-Advanced network as its proving ground.

Nokia agreed a deal with SoftBank Corp to conduct an AI-RAN field trial in commercial traffic conditions in 2027, progressing efforts to validate the technology.

The Finnish vendor stated the trial in Japan would be an important step in SoftBank’s AI-RAN ambitions by assessing the approach in a live network environment.

For Nokia, the trial also advances its AI-RAN commercialisation roadmap by shifting the technology from laboratory development to real-world deployment.

Nokia explained it will combine its AI-native anyRAN cloud RAN software on SoftBank’s core AI-RAN platform AITRAS, along with Nvidia’s ARC platform.

Through a combination of the platforms, Nokia stated AI-RAN would bring radio and AI workloads on to a common platform, helping operators “improve infrastructure utilisation, acceleration innovation and unlock new revenue opportunities”.

Nokia and SoftBank already have an AI-RAN deal in place, backed by an Nvidia accelerated computing node.

SoftBank SVP and CTO Ryuji Wakikawa said the trial is a significant milestone in the transition of AI-RAN from concept to execution.

“We are excited to begin this next phase of validation with Nokia, paving the way for a new era of networks that can deliver both connectivity and AI services.”

Pallavi Mahajan, chief technology and AI officer at Nokia, pointed to the potential for AI-RAN to “unlock new levels of spectral efficiency while providing the distributed intelligence needed to support physical AI”.

• Multiple banking apps in the UK, including Revolut, faced disruptions on Tuesday morning.
• Google Cloud experienced issues with its London-based cloud region and has since said services are coming back.
• Revolut said in a statement that customers' money was safe while it investigated the disruption.

Google said it had largely resolved a cloud outage that appeared to knock out a number of online banking services.

The company said in an update at around 10 a.m. ET on Tuesday that the problem had been mitigated for the most part, with "a very small number" of customers still experiencing issues.

Google had said the outage had been caused by a "power event" at its europe-west2-b zone, which is based in London.

A handful of banking apps and services, including Halifax and Revolut, reported issues on Tuesday that coincided with Google Cloud's disruptions. Some companies said that the Google Cloud outage was the cause, while others attributed it to an unnamed third-party provider.

Users of some affected banking apps said in social media posts early Tuesday that they couldn't make card payments, log in to the app, or transfer money.

"We can confirm that all our customers' money and data are safe. We've been working to fix the issue since it was identified this morning and apologize to anyone affected and for any inconvenience caused," Revolut said in a statement earlier in the day. The outage was due to Google Cloud, a person familiar with the matter said.

"We're aware some customers are having issues with our app and online. We're sorry about this and are working hard to fix it," Halifax posted on X.

Emma, a popular UK budgeting app, also reported outages on Tuesday. "Emma is currently down due to a Google Cloud outage affecting services in London since 7 a.m. This is a technical outage, not a security issue," the company said on X.

Some took to X to share how the outage was disrupting their lives. One person said they'd had to cancel their beauty appointments in Japan, and another said their card was declined at the airport and they couldn't reach the support team.

The outage appears to have affected non-finance companies, too, according to Downdetector, a site that tracks online service disruptions.

Earlier on Tuesday, an X account for DPD, a delivery service, said in a post that its website was affected, and the web-hosting platform SiteGround said the outage has hit its UK data center. SiteGround said in its post that its engineers were working with Google Cloud engineers to address the issue.

The UK's courts and tribunal service said that it was experiencing issues with its cloud-based video tools for remote hearings on Tuesday. "We're working with our technology partners to restore service," an account for the government service wrote in an X post.

The Google Cloud outage comes as the tech giant has competed with Amazon and Microsoft to win business from enterprises, startups, and governments, particularly amid the AI boom. Reliability is a big promise built into these deals, as outages can have costly consequences for customers.

Google is not alone in being affected by outages, though: Amazon, Microsoft, and others have suffered downtime this year.
