AT&T Business expanded the reach of its 400G wavelength connectivity into 16 additional US metropolitan areas, extending the service as enterprises face mounting pressure to support AI-era traffic at scale.

With the 400G wavelength edgeless handoff capability now live across 440,000 properties serving more than 2.3 million business tenants, the mobile operator is targeting rapid deployment within 15 days where eligible.

AT&T stated the 400G rollout is designed to connect AI workloads from any location to the cloud, with security embedded in the network rather than added on top.

The company’s edgeless design approach anchors 400G at key interconnection hubs where cloud, network and enterprise traffic converge. It is currently in more than 130 carrier hotel locations nationwide.

The architecture is intended to deliver consistent handoff and predictable performance without requiring traditional network edge builds at every location or data centre.

Amrit Singh, industry principal for information communications technology at Frost & Sullivan, stated AT&T’s wavelength services reflect the infrastructure rigour required for the AI era, citing the company’s fibre reach and a successful 1.6 Tb/s single-carrier wavelength trial.

For enterprises scaling AI across multiple sites, AT&T noted the ability to avoid stitching together multiple smaller circuits as workloads grow is a key benefit for the service.

Branch locations, campuses and edge environments requiring high-capacity connectivity to centralised compute and cloud services are among the primary use cases for the service.

Cash App's AT&T-based MVNO will offer an unlimited 5G data plan for $40 per month including taxes and fees. The new mobile service is powered by Gigs, the same firm behind the Klarna mobile service that launched last year with the same pricing and is "rolling out to select users, with broader availability planned in the coming months."

Cash App also says it's planning connections to its Cash App Green rewards program and Cash App Families, its setup for managing supervised child and teen accounts.

AT&T unveiled a 24-hour unlimited wireless data service for iPad users in the US, available to any customer regardless of their existing operator for a flat daily rate of $3.

The company claimed to be the first major US wireless provider to offer on-demand connectivity for iPad users on a pay-as-you-go basis. The service is for models with mobile and Wi-Fi connectivity capabilities, with the 24-hour data window beginning shortly after purchase.

AT&T explained it is targeting consumers who do not activate mobile connectivity on compatible iPads, pitching the benefit of short-term network access for periods where users are not in Wi-Fi range.

It highlighted ease of use, stating the service is activated in device settings without the need for a dedicated app.

The first day pass is complimentary, with subsequent purchases charged to a credit or debit card.

Josh Goodell, VP of consumer product management, said the goal is to make connectivity simple across the devices people use most.

The operator positioned the launch as part of a broader effort to simplify connectivity and provide flexible options without long-term commitments.

Model compatibility ranges from seventh-generation iPads to the latest Pro and Air models with M3 chips.

AT&T ultimately plans to expand the service to other 5G-enabled devices including Android tablets, smartwatches, laptops and drones.

Multi-day options are also planned.

AT&T noted data rates may be temporarily reduced during periods of network congestion.

AT&T has introduced a new "Unlimited Day Pass" cellular data offer for iPad users who need brief connectivity instead of signing up for a long-term plan. The day pass is available for $3 in the US starting today, providing 24 hours of unlimited data, with no contracts, subscriptions, or credit checks required.

This offer is available to anyone, including non-AT&T customers, with the 24-hour data activation beginning shortly after purchase. The first day pass is free as part of an introductory deal. There are no caps on speed or data mentioned in AT&T's announcement, but the company says it may "temporarily slow data speeds if the network is …

Interview: AT&T completed a controlled introduction phase of its cloud RAN deployment, with roughly 25 sites running live traffic on Intel’s Sapphire Rapids processors as it plans to aggressively scale deployment when Intel’s next-generation Granite platform arrives over the coming months.

The Sapphire deployment is currently handling the TDD layers of the network, which represent the largest share of traffic, but not yet the full stack.

Rob Soni (pictured), VP of the operator’s RAN architecture, told Mobile World Live (MWL) Granite, which is already in AT&T’s labs, will enable a full stack covering FDD, TDD, NR and LTE from a single server design.

“This is all coming in phased pieces through the fall and early next year,” he said. “We plan to scale more aggressively on Granite than we did on Sapphire.”

He said AT&T expects to move from a few hundred Sapphire sites to thousands on Granite through 2026 and into 2028.

Performance on the Sapphire sites is matching traditional RAN on call drop rates and throughput, Soni said, and the team is beginning to utilise the platform’s promise of faster feature delivery.

The leading example is AI-driven link adaptation, developed with Ericsson, which replaces rules-based scheduling algorithms with a deep neural network.

Trials are showing roughly 10% gains in spectrum efficiency and 15% improvements in individual user throughput, with further benefits expected as AT&T tunes the global Ericsson model to its own network morphology.

“We’ve done a lot of trailing with the kind of global model of Ericsson,” Soni explained. “We’re now in the process of tuning the model to the AT&T morphology, the AT&T usage. That will change the nature, and we expect there to be more gain.”

Halfway point

In cellular networks, Soni stated a base station must determine on every transmission frame which users to serve, what modulation and coding scheme to use and how to balance competing demands across the spectrum.

It is a computationally intense optimisation problem, and the traditional approach has been to encode engineering judgment into static rule sets. The AI model Ericsson developed learns from network behaviour and adapts more fluidly to changing conditions.

Link adaptation is a critical algorithm for determining the overall multiple user performance in a cellular network,” he stated.

Rival T-Mobile US stated in May 2026 it is also trialling Ericsson’s AI-native scheduler with link adaptation on live 5G-Advanced traffic, but Soni noted AT&T has been trialling it since December 2025.

Soni told MWL AT&T is just past the halfway point for switching out Nokia’s RAN gear for Ericsson’s as part of a five year plan to transition 70% of its network traffic to run on open platforms by end of year.

AT&T deepened its partnership with EV maker Rivian, confirming its 5G network will power connectivity inside its R2 model, which is slated for availability from 9 June.

The collaboration builds on a relationship dating to 2023, when AT&T became the connectivity provider for Rivian vehicles across the US and Canada.

With the R2 coming to market, the arrangement expands to cover the automaker’s next-generation platform, ensuring its more affordable mass-market model arrives with the same always-on network backbone as its predecessors.

The operator stated its 5G infrastructure will support faster over-the-air software updates, richer infotainment and real-time services which enable the R2 to improve performance and personalisation over time.

“Connectivity is increasingly central to how vehicles are designed, delivered, and improved,” stated Matt Harden, VP of connected solutions at AT&T.

At an automaker technology conference in the US state of Michigan, AT&T also revealed an expansion of its connected car platform in collaboration with Cisco and LiveOne, the parent of Slacker Radio.

The three-way arrangement is designed to simplify how automakers integrate premium entertainment into connected vehicles. AT&T’s wireless network provides the backbone, Cisco contributes multi-party billing infrastructure through its SIM management platform, and LiveOne will be supplying personalised audio content ranging from curated playlists to live programming.

Rather than requiring each automaker to negotiate separate connectivity deals with individual content providers, AT&T noted its platform acts as a single integration layer.

LiveOne joins existing AT&T partners including iM Media Labs and SiriusXM as part of a content ecosystem now reaching more than 60 of the world’s top automotive brands.
