Ericsson Conducts First Live 6G Trial in US
Ericsson completed the world's first live 6G trial in Texas, demonstrating the technology's ability to power AI robotics and real-time video streaming. The trial utilized new 6G centimeter wave spectrum and a cloud-native infrastructure to process large language model tasks for robotic applications.
The Ericsson trial in Plano, Texas, represents a significant step beyond 5G, utilizing pre-standard 6G architecture. This over-the-air test successfully demonstrated key building blocks like advanced radio hardware and a software-defined air interface. The system's cloud-native design is crucial, allowing it to run on both CPU and GPU hardware, a key flexibility for future network demands. A core feature of this 6G trial is its AI-native framework, designed to handle complex tasks for robotics and autonomous systems. The successful test showed the network could provide the instant, reliable connections necessary for real-time robotic control. This moves beyond current capabilities, where network infrastructure is becoming a critical component of the AI stack itself. The spectrum used is a key differentiator, moving into the "centimeter wave" bands, specifically the 7-15 GHz range, considered a "golden band" for 6G. This is a shift from the millimeter wave (mmWave) bands used for 5G and the even higher terahertz (THz) frequencies initially theorized for 6G. This upper mid-band spectrum is seen as offering a better balance of high capacity and signal coverage. This live trial places the U.S. at the forefront of 6G development, a stated goal of the government to ensure economic competitiveness and national security. While full commercial deployment of 6G is not expected until around 2030, this successful pre-standard test is a critical milestone. The 3rd Generation Partnership Project (3GPP), which oversees mobile standards, has an official timeline targeting the first 6G specifications by the end of 2028. The cloud-native and service-based architecture demonstrated is fundamental to 6G's goals. This approach allows network functions to be broken down into smaller, manageable services that can be deployed and scaled on demand, improving efficiency and reducing costs. It also enables the integration of third-party applications and AI services directly into the network. Beyond robotics, 6G is expected to enable a wide range of futuristic applications. These include holographic telepresence, city-wide digital twins for smart city management, and brain-computer interfaces. The technology also aims to fuse communication with sensing, allowing the network to "see" the physical environment to support advanced autonomous vehicle coordination and drone detection. Ericsson is a major player in a global race toward 6G, competing with other giants like Nokia, Samsung, and Huawei. Nokia, for instance, is leading Europe's 6G flagship initiative, Hexa-X, while Samsung has also conducted successful high-frequency transmission tests. This competition is accelerating research and development, with significant investments from both corporations and national governments.
