ETSI Releases GR ISC 003 Defining 6G ISAC System and RAN Architectures
SHERIDAN, WYOMING - April 13, 2026 - ETSI's Industry Specification Group on Integrated Sensing and Communications (ISG ISAC) has published ETSI GR ISC 003, a technical report establishing the architectural foundations for embedding advanced sensing capabilities directly into future 6G networks. The report examines 17 discrete challenges spanning system architecture, RAN architecture, and lower-layer RAN design, and proposes concrete approaches to each. Its release feeds directly into 3GPP's early-stage exploration of 6G ISAC system and RAN architecture, positioning ETSI-led frameworks at the center of next-generation wireless standardization.
