  1. ECC update: some highlights of ECC’s recent regulatory activities Alexander Gulyaev, ECO • R&TTE CA Plenary meeting • 19 May 2014, Amsterdam

  2. Outline • Outline: • 5GHz Wi-Fi “extension bands”: a complex technical task • 3400-3800 MHz range: updated technical conditions for base stations and terminals • PMSE: securing the future from a spectrum perspective

  3. Recent years ECC regualtory policy aims to ensure the continued liberalisation of existing regulatory provisions (especially where technology neutrality is promoted), the exemption of devices from individual licensing, and how new services may be introduced on a shared-spectrum basis with existing ones Notified Bodies are encouraged to follow ECC Newsletters which address most important activities within the ECC and may have impact on the work of Notified Bodies (most recent ECC Newsletter is of April 2014 (this presentation is based on the content in this Newsletter but tailored to the R&TTE CA context) Current trends in developing new ECC regulatory frameworks

  4. The greater growth is now in data traffic over RLAN networks (Wi-Fi) than over mobiles, although Wi-Fi access points are considered as complementary to mobile internet services. Nomadic and static Wi-Fi usage profiles stipulate the need for higher spectrum bandwidth! Majority of Wi-Fi devices in use today are still operated in the 2.4 GHz band (83.5 MHz wide) and are using 20 MHz or 40 MHz channels. A new generation of Wi-Fi (known as IEEE 802.11ac) will be able to achieve throughput rates sufficient enough to extend existing high-speed fixed broadband infrastructures wirelessly (providing data rates of 30 or 100 Mbps or more when using 80 MHz and/or 160 MHz channels) 5GH Wi-Fi “extension bands”: a complex technical task

  5. EU: Digital Agenda for Europe: sufficient spectrum resources should be available on a harmonized basis to support the evolution (in particular, the use of larger channel bandwidths) of WAS/RLAN technologies EC Mandate to CEPT (September 2013) to develop harmonized technical conditions for WAS/RLAN in the bands 5350-5470 MHz and 5725-5925 MHz ('WAS/RLAN extension bands'). The aim: to enable a future Wi-Fi usage of the whole range 5150-5925 MHz (including the 455 MHz of already designated in 5 GHz spectrum) based on a general authorisation The new WAS/RLAN spectrum bands are also under discussion in the preparation for AI 1.1 of WRC-15 (primary allocation to Mobile Service). 5GH Wi-Fi “extension bands”: a complex technical task

  6. Technical challenge in the 5 GHz: many incumbent users in the band (as well as in the adjacent bands) also have high priority and right to protection, including: the European Earth monitoring programmeGMES (Global Monitoring for Environment and Security), now known as “Copernicus”, and ITS (Intelligent Transport Systems), including safety-related systems The interference situation in the current “5 GHz Wi-Fi bands” (i.e. 5150-5350 MHz and 5470-5725 MHz) should continue to be in the focus of NBs (recent ECC Report 192 on issues with Dynamic Frequency Selection in the 5 GHz range, Final Report on ADCO R&TTE 5 GHz campaign, coordination of follow-up actions at the European level) 5GH Wi-Fi “extension bands”: a complex technical task

  7. Timing: the CEPT work in response to the EC Mandate is divided into three steps: Interim Report (March 2014) - a description of work undertaken and interim results under tasks (1) and (2) of the EC Mandate CEPT Report A (March 2015) – main technical results before WRC-15, and CEPT Report B (July 2016) – ‘sanity check’ after WRC-15 (in order to reconfirm the technical conditions provided in CEPT Report A) 5GH Wi-Fi “extension bands”: a complex technical task

  8. Notified Bodies: follow closely the evolution of the ETSI standards and national regulatory frameworks of European countries in respect of the DFS requirements in Wi-Fi consumer products in the existing 5 GHz bands (5150-5350 MHz and 5470-5725 MHz), based on the conclusions of ECC Report 192 follow and note the outcome of the CEPT work on the technical requirements for the “WAS/RLAN extension bands” (5350-5470 MHz and 5725-5925 MHz) 5GH Wi-Fi “extension bands”: a complex technical task

  9. The 3400-3800 MHz is a large amount of still partly under-used spectrum open for future, truly broadband, mobile applications ECC used over two years for studies to complete its regulatory and technical work for this band since the adoption in December 2011 of a Decision (ECC/DEC/(11)06)This work has resulted in: ECC Report 203, CEPT Report 49, and updated ECC/DEC/(11)06 3400-3800 MHz range: updated technical conditions for base stations and terminals

  10. Scope of review of ECC/DEC/(11)06: TDD was declared as the "preferred" frequency arrangement and FDD – as an "alternative" for the 3400-3600 MHz sub-band (the upper sub-band 3600-3800 MHz was initially harmonized for exclusive TDD use) Block Edge Masks (BEMs) for TDD and FDD modes were developed which are applicable to MFCN base stations with different power levels (i.e. macro, micro, pico and femto BS). 3400-3800 MHz range: updated technical conditions for base stations and terminals

  11. The updated ECC/DEC/(11)06 does NOT contain a BEM for terminals (UE – user equipment), therefore terminals out-of-band emission (OOBE) levels will be specified only in the relevant ETSI standards. HOWEVER: The updated ECC/DEC/(11)06 contains a recommended value of maximum UE in-block power which is set to 25 dBm (it’s specified as e.i.r.p. for UEs designed to be fixed or installed and as TRP for UEs designed to be mobile or nomadic). A tolerance of up to 2 dB has been included in the above limit, to reflect operation under extreme environmental conditions and production spread. A new EC Decision 2014/276/EU (amending the current EC Decision 2008/411/EC on the 3400-3800 MHz) which is binding on EU Member States specifies the maximum UE in-block power value of 25 dBm as “technical conditions for terminal stations” but contains a provision stating that Member States may relax this limit under certain circumstances, for example fixed terminal station. 3400-3800 MHz range: updated technical conditions for base stations and terminals

  12. Notified Bodies: in assessing the compliance of 3400-3800 MHz IMT terminals attention should be paid to the actual relevant national regulation, i.e. the arbitrary chosen maximum in-block power limit which is set in ECC/DEC/(11)06 and EC Decision 2014/276/EU to 25 dBm as a default value. 3400-3800 MHz range: updated technical conditions for base stations and terminals

  13. TV, theater and other show progamme making facilities have a huge public and social importance; look at the public interest to the recent Eurovision contest 2014 in Copenhagen! The need for frequencies (for audio, video and service links) that support the making of programmes, as well as a much wider range of cultural, social and economic activity, are a major element in the frequency management. However, wireless microphones are in international frequency law the 'secondary service‘! CEPT has carried out an extensive series of studies, also in response to the recent EC Mandate which will serve as a technical basis for the Commission's next steps in policy-making towards PMSE (Programme Making and Special Events). PMSE: securing the future from a spectrum perspective

  14. Three elements of the recent CEPT work related to PMSE: Duplex gaps at mobile allocations in 1800 MHz and 800 MHz, and also in the 700 MHz (duplex band and guard band) “L-band”: 1452-1492 MHz range was considered as a potential new space for PMSE, however this is now harmonized by ECC/DEC/(13)03 to mobile supplemental downlink (SDL). 1492-1518 MHz band has recently been identified by CEPT for indoor operation of wireless microphones 1518-1525 MHz band is currently under study Cognitive approaches: more as a means of protecting PMSE from 'white space devices' than as a vehicle for PMSE itself PMSE: securing the future from a spectrum perspective

  15. Major CEPT/ECC deliverables on PMSE: ECC Decision (09)03 on MFCN in the 800 MHz band (Annex 3, section 3.1 – “Technical conditions for PMSE equipment”) ERC Recommendation 25-10 (currently under review): the tuning ranges for PMSE ERC Recommendation 70-03 (Annex 10) ECC Report 191 and an addendum to CEPT Report 50 (usability of center gaps in the 1800 MHz and the 800 MHz mobile allocations): CEPT Report 51: 8 frequency bands between 2 and 8 GHz which were proposed as alternative bands for cordless cameras ECC Report 204: spectrum use and future requirements for PMSE PMSE: securing the future from a spectrum perspective

  16. Need to explore further sharing opportunities to accommodate PMSE spectrum requirements, e.g. in the L-band: the spatial environment of downlink frequencies is much more predictable (given a channelling plan and specific base station siting) than for uplinks with their mobile terminals eventually being placed anywhere… PMSE: securing the future from a spectrum perspective

  17. New technologies for wireless microphones: short and medium term: wireless microphones will remain largely analogue devices, while digital solutions could provide for greater security of quality in environments of light to moderate interference cognitive techniques for individual microphones is rather a long-term option PMSE: securing the future from a spectrum perspective

  18. Notified Bodies: in assessing the PMSE equipment attention should be paid to multiple PMSE frequency options, varying from country to country, and the associated technical conditions in CEPT regulations and relevant ETSI harmonsied standards. More complex technical requirements ensuring compatibility of PMSE with other ‘primary systems’ may be expected in the future that will in turn result in higher complexity of test reports and more sophisticated assessment procedures.
