The SSM may enable new user spectrum authorizations by sending, to a regulator, a request for administrative information, and receiving, from the regulator, a policy and user authorization information for at least one user. The SSM may register a T2U with or without contacting the regulator. The SSM may perform quality based admission control by receiving periodic measurements from a master device of each T2U with an active frequency assignment indicating a Quality of Operation (QoO) experienced by the respective T2U, maintaining a map of an effective QoOs for a plurality of T2Us, and categorizing protection contours associated with each of the plurality of T2Us."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection mechanisms for multi-tiered spectrum access systems","description":"A shared spectrum manager (SSM) may enable spectrum access for Tier 2 Users (T2Us) and Tier 3 Users (T3Us) while provisioning quality of access (QoA) in a dynamic shared spectrum environment while ens","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9743281","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
