Ericsson and participants at a September 2 Seoul policy seminar said mobile networks must evolve into core AI infrastructure as machine-generated traffic expands. Ericsson warned that 40% of global 5G networks lack the minimum uplink capacity required for AI traffic, while seminar speakers said AI-related traffic could increase twofold to fivefold over the next five years. AI glasses, robots and autonomous vehicles will continuously upload camera and sensor data, making predictable uplink performance, latency and security increasingly important. Ericsson identified 5G SA (Standalone), AI-RAN and differentiated connectivity as priorities for South Korea, alongside a transition through 5G Advanced toward AI-native 6G. Participants also called for flexible net-neutrality rules, service-specific quality policies and investment incentives for networks and AI data centers (AIDCs). Telecom capital spending remains uneven, with second-quarter CAPEX down 23.3% at SK Telecom and 70.1% at KT but up 21.5% at LG Uplus during its 5G SA transition. South Korean officials said they plan to include open-architecture AIDCs in the AI Data Center Special Act's enforcement ordinance, while linking support to new services and user benefits.
