3 01. ABOUT SPECTRUM SHARING Spectrum sharing is the general rule but might not always be feasible or desirable and use of refarming might become an option. Spectrum sharing actually refers both to various regulatory approaches in spectrum management fostered by administrations and to technology solutions developed by industry that can be implemented at equipment level or through enhanced systems (e.g. relying on database). Spectrum sharing can take place at different levels from a regulatory perspective: between different radio communication services, whether at international level for services with a global footprint (satellite, aeronautical, maritime), based on provisions in the Radio Regulations and coordination of frequency assignments, or at national level between different applications based e.g. on provisions set in European harmonisation measures between different entities or type of users (e.g. governmental vs commercial use) between different licensed users of the same application (e.g. PMR services, Point-to-point links) between protected primary users and licence-exempt users (e.g. radars and EESS vs 5 GHz RLANs) between different licence-exempt users subject the same regulatory conditions (e.g. 2.4 GHz regulations for wideband data transmission systems) between different licence-exempt users subject to different regulatory conditions (different set of conditions may apply for SRDs in the same frequency band)...

6 L-band: timing availability issue Frequency band MHz harmonised in Europe for Mobile/Fixed Communications Networks Supplemental Downlink (MFCN SDL) since 2013 The WRC-15 identified the frequency bands MHz and MHz for IMT. ECC tasked ECC PT1 to assess relevant timing for harmonisation and availability of the MHz and MHz frequency bands for MFCN. CEPT supports ITU-R harmonisation process CEPT VIEWS on band plan G1 for MHz in recommendation ITU-R M.1036 The CEPT has reviewed the candidate band plans for the implementation of mobile systems in MHz. The CEPT supports band plan G1 as illustrated in the Figure below: Long timeframe required to ensure availability of L band in France Significant refarming work required shared access not adequate Modification of the usage rights in NTFA requires planning of the migration of existing usages Fixed service : 1600 point-to-point radio links in the duplex bands MHz / MHz Frequency band MHz allocated to the military in France and also used by PMSE applications Ongoing authorisation for a digital terrestrial broadcast service in the MHz band. Currently, there is no commercialised service in this band. Public consultation planned by ARCEP to assess the demand Harmonisation process required to encourage industry development

7 GHz: primary band suitable for the introduction of 5G in Europe Key steps for national implementation - Public consultation by ARCEP to assess the demand - French NTFA : adjustment of usage rights towards exclusive allocation for ARCEP together with refarming of limited number of existing microwave links used by home office - Definition of technical conditions to ensure coexistence between mobile and fixed-satellite services Shared access between mobile broadband and receiving Earth stations Initial studies using single entry methodology : definition of iso-e.i.r.p. Ongoing studies by ANFR to assess potential aggregate interference receiving Earth stations About 5 to 10 locations with Earth stations to be protected pending decision on renewal of existing licenses DRAFT RSPG Opinion on spectrum related aspects for next-generation wireless systems (5G) The RSPG considers the MHz band to be the primary band suitable for the introduction of 5G use in Europe even before 2020, noting that this band is already harmonised for mobile networks, and consists of up to 400 MHz of continuous spectrum enabling wide channel bandwidth. This band has the possibility to put Europe at the forefront of the 5G deployment.

8 5 GHz RLANs: possible new mitigation techniques? Existing regulations for 5 GHz : MHz (indoor use only) and MHz WRC-15 discussions Inter-American proposal focusing on possible expansion of RLAN use into the MHz frequency range European Multi-country proposal to broaden the studies to encompass the frequency range MHz Considering the interest by RLAN industry in using the frequency bands MHz and MHz on a global basis as extension bands and that characteristics of 5 GHz RLAN systems are evolving, Recognizing that studies performed in concluded that sharing with EESS in MHz and certain types of radars in MHz and MHz is not feasible. New agenda item for WRC-19 : studies in frequency band MHz Investigation on possible new mitigation techniques. Resolution 239 (WRC-15) Spectrum regulations applicable in Europe to 5 GHz RLANs Decision 2005/513/EC sets the policy rules in terms of vertical sharing i.e. the obligation to use mitigation techniques to ensure protection of identified primary users. Suitable mitigation techniques are described in ETSI EN Other requirements to ensure access to various users and technologies (i.e. horizontal sharing ) to the 5 GHz bands are defined in ETSI EN The standard must provide verifiable mechanisms so as to give confidence to industry in terms of compliance with the legal requirements and in terms of effective protection of primary users.

14 05. Conclusions The trend towards shared access should increase in the context of 5G systems DRAFT RSPG Opinion on spectrum related aspects for next-generation wireless systems (5G) under public consultation RSPG (Radio Spectrum Policy Group) recommends that already-harmonised bands are re-used to support the initial growth of 5G MHz : primary band suitable for the introduction of 5G use in Europe even before 2020, 5G will need to be deployed also in bands already harmonised below 1 GHz, including particularly the 700 MHz band, in order to enable nationwide and indoor 5G coverage. there will be a need to ensure that technical and regulatory conditions for all bands already harmonised for mobile networks are fit for 5G use. Frequency bands above 24 GHz : to give sufficient guidance to industry, the RSPG will aim to identify at the earliest opportunity a suitable band to be made available in Europe. The RSPG believes that considerations of bands above 6 GHz for 5G shall be limited to the bands listed by WRC-15 in order to strengthen the global harmonisation opportunities. This work should focus on the frequency bands proposed by Europe, in particular the bands GHz, GHz and GHz. The RSPG intends to identify which one of these could be harmonised in Europe for early implementation. 14
