The mobile core’s dynamic future: AI, edge, disaster protection, and non-terrestrial networks

Mobile networks are heading into a transitional year as operators push the 5G core to do more than just carry traffic. After T-Mobile US switched on the first nationwide 5G Standalone network in 2020, others followed, laying the groundwork for a more flexible core that can run software, automate decisions, and connect devices beyond traditional cell sites.

Four areas now dominate that roadmap: operators are testing AI in the core to automate operations and improve reliability; shifting compute closer to users through edge access so applications respond faster; hardening networks for disaster protection so service can continue through outages and extreme events; and extending coverage with non-terrestrial networks that use satellites and other platforms. How these pieces come together in 2026 will shape what 5G networks can realistically deliver for users and industries, beyond the early marketing promises.
