Keysight and MediaTek Advance AI‑Driven Uplink Optimization and Model Life Cycle Management for Radio Access Networks

Key Terms

radio access networks technical

Radio access networks are the parts of a mobile network that connect phones and other wireless devices to the operator’s central systems, using antennas, base stations and the wireless signals between them. Think of them as the roads and traffic lights that let cars (devices) reach a city center (the network); investors care because RAN quality and cost affect service coverage, data speeds, customer experience, capital spending and competitive position in mobile and wireless markets.

transmit diversity technical

Transmit diversity is a wireless technology that sends the same signal from multiple antennas or transmission paths so at least one copy arrives clearly, like sending several messengers along different routes to ensure a message gets through. For investors, it matters because it improves connection reliability and coverage, can lower dropped calls and customer complaints, and may boost a product’s competitiveness, network efficiency and potential revenue.

over‑the‑air (ota) updates technical

Over‑the‑air (OTA) updates are wireless software or firmware changes sent remotely to devices like phones, cars, or smart appliances without needing physical access. For investors, OTA capability matters because it lets a company fix bugs, add features, improve security, and extend a product’s useful life quickly and cheaply—similar to sending a package of improvements straight to a customer’s doorstep—which can lower costs, protect brand value, and create recurring service opportunities.

rf digital twin technical

An RF digital twin is a virtual replica of a radio-frequency environment and the wireless equipment that operates in it, used to simulate how signals behave, interact, and interfere before anything is built or deployed. For investors this matters because it lets engineers test designs, predict performance, and fix problems in a low-cost, controlled setting—like a flight simulator for wireless systems—reducing technical risk, speeding product launches, and limiting costly field surprises.

3d ray tracing technical

A rendering technique that simulates how individual rays of light travel, bounce and interact with surfaces to produce highly realistic 3D images; think of tracing the path of a flashlight beam as it hits mirrors, glass and rough walls to create accurate shadows, reflections and color. For investors, it matters because ray tracing drives demand for faster graphics chips, specialized software and cloud rendering services, influencing revenue and capital spending across gaming, film, design and data-center hardware suppliers.

Working prototype shows how artificial intelligence-radio access network techniques can adapt to site conditions and improve uplink performance at scale

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) and MediaTek announced a working prototype that advances AI‑driven uplink optimization and model life cycle management for next‑generation radio access networks (RAN). The prototype will be demonstrated at Mobile World Congress 2026 and shows how AI‑enabled, RAN-assisted intelligence can improve uplink performance in real time while remaining effective over time through practical model retraining and over‑the‑air (OTA) updates, helping operators and ecosystem partners accelerate the transition to networks.

As networks evolve, maintaining consistent uplink performance becomes increasingly challenging. Coverage conditions vary widely across urban, rural, indoor, and hard-to-reach locations. Traditional transmitter diversity techniques are often static, which can limit performance as conditions change. At the same time, AI models trained in one environment may not perform the same across all deployment scenarios and updating those models in live networks can be operationally complex. Operators need an approach that is accurate, site‑aware, and easy to maintain.

Keysight and MediaTek address this need by combining RAN‑assisted AI decision‑making, site‑specific model retraining, and over-the-air (OTA) model updates in a controlled test environment that mimics real-world network conditions. The prototype leverages Keysight’s Channel Studio RaySim and its Network and Channel Emulation solutions to create realistic, repeatable validation scenarios. This enables measurable gains in uplink throughput, spectral efficiency, and reliability while reducing the operational effort required to support diverse deployment environments. The work aligns with the objectives of the AI‑RAN Alliance, supporting scalable deployment and continuous optimization of AI in the RAN.

Mingxi Fan, Senior General Manager of Wireless Technology Group, MediaTek, said: “We’re looking forward to highlighting how instrumental uplink performance enhancement will be in scaling future mobile networks so they can support AI-era applications more efficiently. Transmit diversity is a promising technique to be implemented at the device level so it can work across a wide variety of network environments, and our collaboration with Keysight demonstrates that through open infrastructure and device cooperation, our technology will facilitate practical, scalable AI-native RAN deployments.”

Peng Cao, Vice President and General Manager, Wireless Test Group, Keysight, said: “Together with MediaTek, we have demonstrated a novel AI-enabling-AI technique which helps address the increasing demand on mobile networks’ uplink performance, capacity, and consistent end user experiences driven by AI and AR applications. This involves training and testing the AI-enhanced transmitter model in the UE with high-fidelity real-world training datasets generated from Keysight’s RF digital twin channel emulation solutions with 3D ray tracing capabilities.”
