5 terms

radio access network (ran) technical

"AI-driven radio access network (RAN) control for next-generation 6G mobile"

A radio access network (RAN) is the collection of antennas, base stations and related equipment that connects mobile devices to the broader phone and internet network, acting like a bridge and traffic controller for wireless signals. It matters to investors because RAN design and upgrades determine how fast and reliably networks deliver services, influence a carrier’s costs and rollout speed for new technologies (like 5G), and shape which vendors or operators gain revenue and competitive advantage.

digital twin technical

"evaluated using VIAVI's digital twin and TeraVM AI RAN Scenario"

A digital twin is a live virtual replica of a physical asset, process, or system that mirrors real-world behavior using data and models so users can test changes, predict problems, and measure performance without touching the real thing. For investors, digital twins matter because they can lower maintenance costs, speed product development, improve uptime and reliability, and make future cash flows and risks easier to forecast — like using a flight simulator to safely train and tune a real airplane.

beamforming technical

"In conventional beamforming, base stations select and control transmission beams"

Beamforming is a technology that steers wireless signals in a focused direction so devices receive stronger, clearer connections instead of spreading radio waves everywhere. Think of it like aiming a flashlight beam at a specific person rather than lighting an entire room: it boosts speed, range, and reliability while reducing interference. For investors, beamforming matters because it can improve product performance, enable new services, lower network costs, and create competitive advantages for companies selling chips, equipment, or connectivity services.

user equipment (ues) technical

"measurements reported by user equipment (UEs). In the demonstration, DOCOMO's"

User equipment (UEs) are the devices people and machines use to connect to mobile networks—smartphones, tablets, laptops with cellular modems, and Internet-of-Things sensors. Think of them as the customer-side doorways that determine how many users can enter and what services they can use; more or better UEs drive demand for network capacity, software, and upgrades, affecting device makers, carriers and investors in related infrastructure.

network simulator technical

"AI RAN Scenario Generator (AI RSG) network simulator. Results confirm that"

A network simulator is a software tool that creates a virtual copy of a computer or communications network so engineers can test how it will behave without touching real equipment. For investors, it matters because it helps companies identify performance limits, security weaknesses, and likely costs before rolling out new services—like a flight simulator for a plane, letting managers spot problems early and reduce the risk and expense of real-world failures.

Up to 20% throughput improvement demonstrated through control-overhead reduction using digital twin, AI

CHANDLER, Ariz., March 2, 2026 /PRNewswire/ -- NTT DOCOMO INC. and VIAVI Solutions Inc. (VIAVI) (NASDAQ: VIAV) have successfully completed a joint study demonstrating AI-driven radio access network (RAN) control for next-generation 6G mobile communications. The results will be showcased at VIAVI's Stand 5B18 at Mobile World Congress (MWC) Barcelona 2026, which takes place March 2-5 in Barcelona, Spain.

In conventional beamforming, base stations select and control transmission beams based on network quality measurements reported by user equipment (UEs). In the demonstration, DOCOMO's Self-awareness Network concept was evaluated using VIAVI's digital twin and TeraVM AI RAN Scenario Generator (AI RSG) network simulator. Results confirm that reducing control overhead improves the system throughput by up to 20% as it frees up wireless resources for data transmission.

The demonstration was conducted in a simulated environment modeling multiple base stations around the Tokyo Station area. Each base station selected the optimal beam for each UE from eight candidate beams based on predicted network quality, with less measurement and reporting of network quality at the UE. Predictions were enabled by the VIAVI AI RSG, with measurements generated by the digital twin.

"This demonstration shows that the Self-awareness Network concept significantly reduces the need for conventional network quality measurements and UE reporting," said Ian Langley, Senior Vice President, Wireless Business Unit, VIAVI. "Intelligent technologies such as tailored network digital twins and AI-powered simulators based on high-quality, trusted, real-world data enable highly efficient network control."

"AI and digital twin are expected to be deployed across a broad range of industries, and AI for network will contribute to the full spectrum of 6G values. We believe that this cooperation between the two companies will contribute to the realization of 6G technologies, including AI for network," said Hiroyuki Oto, Senior Vice President, General Manager of 6G-Tech Department, NTT DOCOMO.

DOCOMO's Self-awareness Network is a concept leveraging AI and digital twin technologies to improve network performance and efficiency across diverse radio environments. Network quality is evaluated within a digital twin environment using data such as location information and radio propagation characteristics to determine optimal network control. Network control is then performed based on these evaluation results, whereby the utilization of AI technology can enable real-time adaptation to dynamic environments.

DOCOMO and VIAVI will continue to advance studies on 6G mobile communications. The two companies will also further explore related technologies, including AI and digital twins.
