Ericsson, AT&T and MediaTek completed North America’s first trial of Layer 1/Layer 2 Triggered Mobility on AT&T’s 5G Advanced network, cutting handover interruption by up to 25% versus Layer 3 and up to 40% in tests. The trial establishes a foundation for AI-powered mobility aiming at zero latency and jitter.
Ericsson collaborated with AT&T and MediaTek to complete the first trial of Layer 1/Layer 2 Triggered Mobility on a live AT&T 5G Advanced network in North America. Testing showed handover interruption time reduced by up to 25% compared to Layer 3 mobility, with lab scenarios indicating potential cuts up to 40%.
The LTM feature shortened handover delays to enable smoother, more reliable connectivity for extended reality, physical AI, immersive video conferencing and critical IoT services. Reduced interruptions support continuous data exchange, low jitter and predictable latency necessary for AI-driven edge and cloud applications.
Ericsson has led LTM development and standardization in 3GPP, positioning the feature as a differentiator in its Radio Access Network portfolio. Successful in-field results bolster Ericsson’s competitive edge and lay groundwork for commercial rollouts of AI-powered mobility solutions aiming at zero latency and jitter.
