Licensed Shared Access (LSA) — Regulatory background and view of Administrations

This paper reflects the view of Conférence Européenne des Postes et des Télécommunications (CEPT) Administrations on status and current work on Licensed Shared Access (LSA), related to European Communication Committee (ECC) Decisions and Reports as well as to the current regulatory framework on licensing and sharing. It explains similarities and differences between the grandfathering approach Authorized Shared Access (ASA) and LSA. The latter provides the communication basis for an enhanced future solution for more flexible sharing and is unanimously agreed within the CEPT and the Radio Spectrum Policy Group (RSPG), the high-level advisory group of European Union (EU) Member States that assists the European Commission (EC) in the development of radio spectrum policy. Reasoned by the duplicities of the approaches the paper aims to compare among the qualities and justifications of both sharing approaches, LSA and ASA. Especially the comprehensive approach provided by the framework of LSA - as amended by CEPT and EC - is highlighted, noting the relevant circumstances of both entities. Additional focus has been placed on the draft ECC Decision on “Harmonised technical and regulatory conditions for the use of the band 2.3-2.4 GHz for MFCN” [1] and its background, especially on its requested implementation via the LSA concept.
