- 8. 8 Issue: Massive amounts of capacity required for exploding Mobile Traffic ! Source: Mobile DataTraffic expected by 2017 - CiscoVisual Networking Indexing Source: UMTS ForumWhite Paper, 2012
- 9. 9 In the context of 5G activities, a 1000(0)x increase of capacity is targeted New dedicated licensed bands (e.g., spectrum under discussion towards WRC-15) Issue: limited opportunities Spectrum Sharing (e.g. Licensed Shared Access in 2.3- 2.4 GHz in Europe) New mmWave spectrum (10/28- 90 GHz, licensed/unicensed) New rules for unlicensed Spectrum for WiFi (5 GHz) or TVWS In the literature, typically the following working directions are addressed • Spectrum • Spectral Efficiency • Base Station Densification
- 10. 1 0 European Commission issued standardization mandate (M/512), ETSI develops corresponding Licensed Shared Access (LSA) Standards in respose to the mandate European Regulators collaborate closely with ETSI in order to resolve Regulation hurdles, defining for example spectrum access conditions For Licensed Shared Access in 2.3-2.4 GHz (CEPT WG FM PT52/53) Integrated approach to dynamically authorizing access to the Priority Access and General Authorized Access (GAA) tiers of the 3.5 GHz Band: approach towards implementing the next generation of spectrum management systems ETSI develops standards for Licensed Shared Access, in particular A System Architecture Design standard is in preparation PoliticalRegulatorsStandards
- 11. 1 1 European Regulators considerTVWS Access in 470-790 MHz, in Particular in CEPT Working Group Frequency Management, Project Team PT53 Provision of rules forTVWS Access, use of the spectrum with geolocation based channel allocation. ETSI published and still elaborates standards for opportunistic And/or coordinated access toTVWS. A Harmonized Standard for OpportunisticTVWS Access was recently adopted. IEEE published severalTVWS related standards, in particular IEEE 802.11af is an extension ofWiFi toTVWS spectrum („super WiFi“) „White Space“ (ETSI TR 102945): part of the spectrum, which is available for a radio communication application (service, system) at a given time in a given geographical area on a non-interfering / non- protected basis with regard to primary services and other services with a higher priority on a national basis.

- 12. • Based on EC Mandate M/512, ETSI ERM/RRS have developed a Shared Spectrum related System Reference Document (SRdoc): TR 103 113 • Mobile broadband services in the 2 300 MHz – 2 400 MHz frequency band under Licensed Shared Access regime, the following example architecture was presented:
- 13. Key system components include: • The LSA Repository is a data-base which receives a-priori information on future availability of LSA spectrum to concerned cellular operators – as well as information on exclusion zones, protection zones and future intended requests for vacating LSA bands, triggered by Incumbents following the conditions in the Sharing Agreement. • The LSA Controller typically accesses the information in the LSA Repository and processes it in order to identify specific spectrum opportunities to be granted to cellular operators for a specific geographic area, a specific period of time and a specific spectrum band. Typically, the operator requests access to LSA spectrum for a given Base Station / Cell or a group of Base Stations / Cells. The LSA Controller exploits all available information and identifies the best available solutions for the concerned cellular operator, taking into account the information provided by the Incumbents to the LSA Repository, the requirements of the concerned cellular operator (taking for example specific infrastructure configurations and preferences into account) and possibly statistical historical data, concerning the behavior of the Incumbent, for example with respect to a possible emergency vacating of the LSA bands (in accordance to the applicable Sharing Agreement). • The Operations, Administration and Management (OA&M) entity is the contact point of the concerned cellular operator with the LSA system and will interact with the LSA Controller in order to authorize/update/terminate access to the concerned LSA bands over geographic area, time and spectrum band.
