Ericsson Technology Review

Ericsson Technology Review aims to encourage an open discussion about the potential, practicalities, and benefits of a wide range of technical developments, and provide insight into the key emerging innovations shaping the future.

The network performance impact of generative AI services

Generative artificial intelligence is moving from the data center to the pocket and the face, and many of the applications driving this shift send far more data than they receive. This net-new, uplink-heavy traffic is placing novel demands on 5G networks built around the downlink. Our latest research, based on three real-world deployment scenarios, demonstrates that today’s networks are already coverage-deficient in the uplink and indicates that targeted 5G radio access network features can meet the first wave of generative AI growth.

Erik Ekudden on emerging GenAI services

Emerging GenAI services depend on uplink capacity, presenting a challenge for today’s downlink-optimized networks. The cell edge is where uplink issues arise first. However with the right mix of 5G RAN software features and radio modernization in each deployment can greatly improve uplink performance at the cell edge. The ability to meet future demand requires treating uplink as a 6G design priority from the start.
