An international collaboration between ETSI and the Wireless Innovation Forum has released a joint technical report analyzing dynamic spectrum sharing use cases for critical services like PMSE, industrial automation, PPDR, and drone control. The document evaluates existing standardized frameworks including LSA, eLSA, AFC, and CBRS, concluding that AFC and eLSA are strong candidates for ensuring incumbent protection while CBRS offers a foundation for native inter-system coordination. To address spectrum scarcity and the specific high-quality-of-service requirements of these time- and space-limited applications, the authors propose specific adjustments to these frameworks to enable automated, ad-hoc private network deployments. These findings were presented at the European Spectrum Management Conference in Brussels to guide regulators worldwide in adopting more flexible spectrum sharing solutions.
