6G Increasingly Looks Evolutionary, Says Dell’Oro

Why It Matters

By emphasizing cost‑per‑bit improvements and infrastructure reuse, the report signals a shift in capex strategy that will influence vendor roadmaps and operator investment cycles. Understanding these dynamics helps stakeholders anticipate where technology spend and competitive advantage will flow in the next decade.

Key Takeaways

• 6G baseline relies on Massive MIMO macro below 8.4 GHz
• AI is built into RAN hardware from the start
• Efficiency gains projected at 10‑50 % drive investment decisions
• Small cells remain key for densification; early rollout targets outdoor macro
• Cloud RAN likely by 2030, yet overall adoption pace remains uncertain

Pulse Analysis

The consensus that 6G will evolve from the 5G foundation reshapes how carriers plan their networks. Rather than betting on entirely new hardware, operators are expected to repurpose the existing macro cell grid, expanding bandwidth in contiguous blocks below 8.4 GHz. This approach minimizes the need for costly new site construction, a crucial factor given that the radio access network accounts for less than 15 % of total wireless spend. By focusing on efficiency—targeting a 10 % to 50 % reduction in cost‑per‑bit—operators can justify incremental upgrades while keeping capital expenditures in line with modest traffic growth forecasts.

Artificial intelligence is moving from an optional add‑on to a built‑in feature of 6G radios. Vendors such as Ericsson are already shipping AI‑ready silicon with dedicated neural‑network accelerators, enabling real‑time optimization of spectrum use, power consumption, and handover decisions. This AI‑native RAN promises not only operational savings but also the ability to support emerging workloads like digital twins, autonomous systems, and continuous sensor streams. While the exact commercial traction of these use cases remains uncertain, the integration of AI at the radio layer positions networks to adapt quickly to shifting traffic patterns and to extract value from data‑intensive applications.

For the broader ecosystem, the evolutionary narrative influences both Open RAN and Cloud RAN trajectories. Programmability and software‑centric operations are gaining priority over pure vendor diversity, nudging the industry toward more flexible, virtualized architectures. However, Dell’Oro cautions that widespread Cloud RAN deployment by 2030 is still a probability, not a certainty, and multi‑vendor RAN adoption appears unlikely. Stakeholders should therefore monitor how quickly operators translate efficiency promises into real‑world deployments, as this will dictate the pace of hardware refresh cycles, the relevance of ISAC capabilities, and the overall competitive landscape for telecom equipment suppliers.
