AT&T Partners with Ericsson and MediaTek on 5G Mobility Trial Cutting Handover Interruptions by 40%
T•AT&T worked with Ericsson and MediaTek to complete North America’s first trial of Ericsson’s LTM mobility feature on its 5G RAN, achieving up to 40% faster handovers and cutting data interruption by 25% versus legacy mobility. The trial paves the way for low-latency AI, XR, IoT and immersive conferencing services.
1. Trial Partnership and Technology
AT&T collaborated with Ericsson and MediaTek to test Ericsson’s Layer 1/Layer 2 Triggered Mobility (LTM) feature on its live 5G RAN in North America, marking the first in-field deployment of this advanced mobility protocol. The integration into AT&T’s network infrastructure allowed real-world evaluation of seamless handover performance.
2. Performance Outcomes
Field testing showed LTM achieved up to a 40% reduction in handover interruption time and cut data interruption during cell changes by 25% compared with legacy mobility protocols. These gains translated into more consistent data rates and lower handover failure rates for moving users and devices.
3. Implications for AT&T's Services
By delivering near-seamless connectivity, LTM supports latency-sensitive use cases such as extended reality applications, time-critical IoT, immersive video conferencing and future AI-driven services. The enhancement strengthens AT&T’s network foundation for emerging high-performance and mission-critical applications.
