The trial aims to enable seamless connectivity for extended reality, physical AI, and time-critical communications, paving the way for 6G.", "body_md": "Ericsson, AT&T and Taiwanese chipmaker Mediatek collaborated on low-latency technology designed to reduce handover interruptions.\n\nSaid to be a first for North America, the in-field trial deployed Ericsson Low-Latency Mobility supporting Layer 1/Layer 2 (L1/L2) triggered mobility (LTM) on the AT&T network while leveraging Ericsson’s radio access network (RAN) technology.\n\nThe Swedish vendor claimed LTM cut data interruption during cell change by up to 25% versus legacy Layer 3 mobility. Part of Ericsson’s 5G Advanced Critical IoT subscription, the firm's Low-Latency Mobility tech aims to reduce such interruption time for faster, more reliable handovers, with the field trial paving the way for extended reality (XR) and time‑critical communications use cases, as well as immersive video conferencing and cloud applications.\n\nAs to be expected, a lot of these use cases will be driven by AI's impact on uplink by nascent consumer tech such as smart glasses. On the XR side, AI can be used in industrial settings for real‑time scene reconstruction, edge‑assisted perception, and connected vehicle analytics, helping to establish the long-mooted B2B metaverse.\n\nThat vision has long been set back by latency issues as affecting data exchange and jitters. According to Ericsson, the final goal is to achieve zero latency and jitter in highly mobile environments.\n\nThis would [also help power physical AI](https://www.sdxcentral.com/control-plane/mwc-robots-see-telcos-transform-into-token-tollsters/), with factory-based robots - and perhaps even those in a home settings - able to receive and react in real time to instructions and changes in command or in the area around them.\n\nThe field trial also further validates next-gen 5G technologies on the path to 6G, with Mårten Lerner, Ericsson's head of networks strategy & product management commenting: “This milestone shows how 5G Advanced can translate into a better user experience with truly seamless connectivity needed for extended reality and physical AI. Together with AT&T and MediaTek, we’re demonstrating how smoother mobility can help deliver more responsive and reliable services for people and industries that depend on connectivity every moment they are on the move.”\n\n## Ericsson partner trials\n\nThe field trial is not Ericsson's first rodeo with either partner. [AT&T for example](https://www.sdxcentral.com/news/att-aced-rapp-deployment-in-brownfield-open-ran-win/) last summer deployed a third-party rApp on its live production network in a brownfield environment using Ericsson’s service management and orchestration (SMO) platform.\n\nMore recently at this year's Mobile World Congress (MWC), Mediatek held a 6G demo with Ericsson revolving around the data requirements of AI and 6G-native devices such as smart glasses. The demo integrated a user equipment (UE) prototype from Mediatek comprising radios and baseband processing up to the IP layer, as coupled with an Ericsson RAN.\n\nThe North American field trial expands on this demonstration, with Dr. HC Hwang, general manager of wireless communication systems and partnerships at MediaTek saying the collaboration proved LTM \"helps deliver faster, more reliable handovers and a steadier data rate throughout the device connection, capabilities that are essential for critical IoT and advanced consumer experiences like XR.\"\n\n“Our work with Ericsson and MediaTek across AT&T and field trials demonstrates that LTM can improve mobility performance where it counts – on the move – so that customers experience more consistent connections for cloud applications and immersive video conferencing today and are ready for next-gen XR tomorrow. This level of mobility consistency is also foundational for AI-enabled services that rely on real-time edge and cloud processing as users and devices move across the network,” added Rob Soni, VP RAN technology, AT&T.", "url": "https://wpnews.pro/news/ericsson-at-t-fight-lag-with-5g-advanced-field-trial", "canonical_source": "https://www.sdxcentral.com/news/ericsson-att-fight-lag-with-5g-advanced-field-trial/", "published_at": "2026-07-08 13:50:00+00:00", "updated_at": "2026-07-08 17:16:29.956475+00:00", "lang": "en", "topics": ["artificial-intelligence", "autonomous-vehicles", "ai-infrastructure", "ai-products"], "entities": ["Ericsson", "AT&T", "MediaTek", "Mårten Lerner", "Rob Soni", "Dr. HC Hwang"], "alternates": {"html": "https://wpnews.pro/news/ericsson-at-t-fight-lag-with-5g-advanced-field-trial", "markdown": "https://wpnews.pro/news/ericsson-at-t-fight-lag-with-5g-advanced-field-trial.md", "text": "https://wpnews.pro/news/ericsson-at-t-fight-lag-with-5g-advanced-field-trial.txt", "jsonld": "https://wpnews.pro/news/ericsson-at-t-fight-lag-with-5g-advanced-field-trial.jsonld"}}
