5.1Assumptions
Scenario SCN-XT09-CMP-01: what is assumed, and what is held constant.
- Baseline
- the 2026 reference state in this edition
- Drivers
- operators add AI compute to radio sites for 5G-Advanced while the first normative 6G specifications freeze only in 2028
- Analogues
- the vendor announcement of 2025 and the Release 21 timetable310
- Interventions
- none modelled: the specification describes the unmitigated case
- Run state
- narrative specification; quantified run scheduled for 2027
5.2The cascade, step by step
- 1
AIC → INF
operators begin field evaluations of AI-RAN platforms
2026
- 2
INF → ENE
site power rises where compute is added; energy per bit is not measured
2024
- 3
FIN → INF
capital commits to platforms before 6G text freezes
2025
- 4
TRD → INF
supplier concentration limits the platform choices
2025
- 5
GOV → INF
spectrum decisions and national rules diverge
2026
- 6
ENE → CLI
network energy enters emissions reporting
2024
5.3The scenario as a table of steps
How the shock in scenario SCN-XT09-CMP-01 would travel through 6G, AI-RAN and Next-Generation Connectivity’s coupled systems, step by step, under the assumptions the edition states.
| Step | What happens | Source |
|---|---|---|
| 01 AI compute to infrastructure | Operators begin field evaluations of AI-RAN platforms. Analogue or source: 2026. | Edition XT-09, scenario SCN-XT09-CMP-01, step 1 |
| 02 Infrastructure to energy | Site power rises where compute is added; energy per bit is not measured. Analogue or source: 2024. | Edition XT-09, scenario SCN-XT09-CMP-01, step 2 |
| 03 Finance to infrastructure | Capital commits to platforms before 6G text freezes. Analogue or source: 2025. | Edition XT-09, scenario SCN-XT09-CMP-01, step 3 |
| 04 Trade to infrastructure | Supplier concentration limits the platform choices. Analogue or source: 2025. | Edition XT-09, scenario SCN-XT09-CMP-01, step 4 |
| 05 Governance to infrastructure | Spectrum decisions and national rules diverge. Analogue or source: 2026. | Edition XT-09, scenario SCN-XT09-CMP-01, step 5 |
| 06 Energy to climate | Network energy enters emissions reporting. Analogue or source: 2024. | Edition XT-09, scenario SCN-XT09-CMP-01, step 6 |
