Indosat Ooredoo Hutchison, Nokia and Nvidia AI-RAN research center in Indonesia amongst telco skepticism

Indosat Ooredoo Hutchison (Indosat) Nokia, and Nvidia have officially launched the AI-RAN Research Centre in Surabaya, a strategic collaboration designed to advance AI-native wireless networks and edge AI applications across Indonesia. This collaboration, aims to support Indonesia’s digital transformation goals and its “Golden Indonesia Vision 2045.” The facility will allow researchers and engineers to experiment with combining Nokia’s RAN technologies with Nvidia’s accelerated computing platforms and Indosat’s 5G network.

According to the partners, the research facility will serve as a collaborative environment for engineers, researchers, and future digital leaders to experiment, learn, and co-create AI-powered solutions. Its work will centre on integrating Nokia’s advanced RAN technologies with Nvidia’s accelerated computing platforms and Indosat’s commercial 5G network. The three companies view the project as a foundation for AI-driven growth, with applications spanning education, agriculture, and healthcare.

The AI-RAN infrastructure enables high-performance software-defined RAN and AI workloads on a single platform, leveraging Nvidia’s Aerial RAN Computer 1 (ARC-1). The facility will also act as a distributed computing extension of Indosat’s sovereign AI Factory, a national AI platform powered by Nvidia, creating an “AI Grid” that connects datacentres and distributed 5G nodes to deliver intelligence closer to users.

Nezar Patria, vice minister of communication and digital affairs of the Republic of Indonesia said: “The inauguration of the AI-RAN Research Centre marks a concrete step in strengthening Indonesia’s digital sovereignty. The collaboration between the government, industry, and global partners such as Indosat, Nokia, and Nvidia demonstrates that Indonesia is not merely a user but also a creator of AI technology. This initiative supports the acceleration of the Indonesia Emas 2045 vision by building an inclusive, secure, and globally competitive AI ecosystem.”

Vikram Sinha, president director and CEO of Indosat Ooredoo Hutchison said: “As Indonesia accelerates its digital transformation, the AI-RAN Research Centre reflects Indosat’s larger purpose of empowering Indonesia. When connectivity meets compute, it creates intelligence, delivered at the edge, in a sovereign manner. This is how AI unlocks real impact, from personalised tutors for children in rural areas to precision farming powered by drones. Together with Nokia and Nvidia, we’re building the foundation for AI-driven growth that strengthens Indonesia’s digital future.”

From a network perspective, the project demonstrates how AI-RAN architectures can optimize wireless network performance, energy efficiency, and scalability through machine learning–based radio signal processing.

Ronnie Vasishta, senior vice president of telecom at Nvidia added: “The AI Grid is the biggest opportunity for telecom providers to make AI as ubiquitous as connectivity and distribute intelligence at scale by tapping into their nationwide wireless networks.”

Pallavi Mahajan, chief technology and AI officer at Nokia said: “This initiative represents a major milestone in our journey toward the future of AI-native networks by bringing AI-powered intelligence into the hands of every Indonesian.”

Wireless Telcos are Skeptical about AI-RAN:

According to Light Reading, the AI RAN uptake is facing resistance from telcos. The problem is Nvidia’s AI GPUs are very costly and not GPUs power-efficient enough to reside in wireless base stations, central offices or even small telco data centers.

Nvidia references 300 watts for the power consumption of ARC-Pro, which is much higher than the peak of 40 watts that Qualcomm claimed more than two years ago for its own RAN silicon when supporting throughput of 24 Gbit/s. How ARC-Pro would measure up on a like-for-like basis in a commercial network is obviously unclear.

Nvidia also claims a Gbit/s-per-watt performance “on par with” today’s traditional custom silicon. Yet the huge energy consumption of GPU-filled telco data centers does not bear that out.

“Is there a case for a wide-area indiscriminate rollout? I am not sure,” said Verizon CTO Yago Tenorio, during the Brooklyn 6G Summit, another telecom event, last week. “It depends on the unit cost of the GPU, on the power efficiency of the GPU, and the main factor will always be just doing what’s best for the basestation. Don’t try to just overcomplicate the whole thing monetizing that platform, as there are easier ways to do it.”

“We have no way to justify a business case like that,” said Bernard Bureau, the vice president of wireless strategy for Canada’s Telus, at FYUZ. “Our COs [central offices] are not necessarily the best places to run a data center. It would mean huge investments in space and power upgrades for those locations, and we’ve got sunk investment that can be leveraged in our cell sites.”

Light Reading’s Iain Morris wrote, “Besides turning COs into data centers, operators would need to invest in fiber connections between those facilities and their masts.”

How much spectral efficiency can be gained by using Nvidia GPUs as RAN silicon?

“It’s debatable if it’s going to improve the spectral efficiency by 50% or even 100%. It depends on the case,” said Tenorio. Whatever the exact improvement, it would be “really good” and is something the industry needs, he told the audience.

In April, Nokia’s rival Ericsson said it had tested “AI-native” link adaptation, a RAN algorithm, in the network of Bell Canada without needing any GPU. “That’s an algorithm we have optimized for decades,” said Per Narvinger, the head of Ericsson’s mobile networks business group. “Despite that, through a large language model, but a really small one, we gained 10% of spectral efficiency.”

Before Nvidia invested in Nokia, the latter claimed to have sufficient AI and machine-learning capabilities in the custom silicon provided by Marvell Technology, its historical supplier of 5G base station chips.

Executives at Cohere Technology praises Nvidia’s investment in Nokia, seeing it as an important AI spur for telecom. Yet their own software does not run on Nvidia GPUs. It promises to boost spectral efficiency on today’s 5G networks, massively reducing what telcos would have to spend on new radios. It has won plaudits from Vodafone’s Pignatelli as well as Bell Canada and Telstra, both of which have invested in Cohere. The challenge is getting the kit vendors to accommodate a technology that could hurt their own sales. Regardless, Bell Canada’s recent field trials of Cohere have used a standard Dell server without GPUs.

Finally, if GPUs are so critical in AI for RAN, why has neither Ericsson or Samsung using Nvidia GPU’s in their RAN equipment?

Morris sums up:

“Currently, the AI-RAN strategy adopted by Nokia looks like a massive gamble on the future. “The world is developing on Nvidia,” Vasishta told Light Reading in the summer, before the company’s share price had gained another 35%. That vast and expanding ecosystem holds attractions for RAN developers bothered by the diminishing returns on investment in custom silicon.”

“Intel’s general-purpose chips and virtual RAN approach drew interest several years ago for all the same reasons. But Intel’s recent decline has made Nvidia shine even more brightly. Telcos might not have to worry. Nvidia is already paying a big 5G vendor (Nokia) to use its technology. For a company that is so outrageously wealthy, paying a big operator to deploy it would be the next logical step.
