  8. ECC deliverables currently under the public consultation ECC deliverables open for public consultation are available at: http://www.cept.org/ecc/tools-and-services/ecc-public-consultation

  9. Draft ECC Report 192 (under the public consultation until 05/12/2013 and ADCO R&TTE 5 GHzcampaign (finalized in October 2013) are complementary studies aimed at finding an efficient European solution to the interference problem from WAS/RLANs to 5 GHz meteorological radars: ADCO R&TTE 5 GHz campaign’s report is based on the data from 21 EU Member States ECC Report 192 is based on the responses from 33 CEPT member countries to the WGFM questionnaire Draft ECC Report 192: the current status of DFS in 5 GHz

  10. ECC Report 192 addresses all reported WAS/RLAN → meteorological radar interference scenarios: All studied interference cases to meteorological radars were caused by outdoor WAS/RLAN fixed installations operating co-channel with radars A considerable number of the reported interference cases were caused by equipment where the DFS mechanism was disabled In some cases, higher gain antennas were used resulting in e.i.r.p. levels above the regulatory limits The ECC Report also identifies a case where DFS was implemented but WAS/RLANs were still causing interference Draft ECC Report 192: the current status of DFS in 5 GHz

  11. ECC Report 192 attempts to cover a European-wide as well as international dimension of the problem and the related activites: Reference to ITU Recommendation ITU-R M.1638 which recognizes meteorological radars as safety-of-life service Section on ADCO’s 5 GHz campaign which will be updated based on the final results of ADCO’s report Draft ECC Report 192: the current status of DFS in 5 GHz (2)

  12. ECC Report 192 appeals to all involved parties in order to perform harmonised actions aimed at alleviation of the interference problem: The ECC Report contains an entire set of recommendatoins to all stakeholders, including those to ETSI and Notified Bodies A major common point in both ECC and ADCO studies is a proposal for closer cooperation between interference management authorities (installation issues, like indoor/outdoor, antenna gains etc.) and market surveillance authorities (compliance with the essential requirements) Draft ECC Report 192: the current status of DFS in 5 GHz (3)

  13. ECC Report 192: recommendations to MSA In those cases where the WAS/RLAN is operating co-channel with the radar and is causing interference into the radar, no effort should be made to solve the interference case by: • re-configuring the WAS/RLAN equipment to a different channel, or by • re-enabling DFS again (where it was disabled), or by • reducing the TX-output power. Market enforcement authorities shall not allow such equipment to be operated or remain in use. The case should be passed over to the national MSA for an appropriate action that can be, for example, the application of the “safeguard clause” procedure

  14. ECC Report 192: recommendations to MSA (2) • Interferences due to equipment placed on the market at an earlier stage (compliant with an earlier standard version) should be dealt with on a case by case basis to solve the problem • Enforcement authorities should inform WAS/RLAN users about the consequences of all kinds of illegal use of WAS/RLAN equipment, i.e. about the interference to meteorological radars which may compromise safety of life

  15. ECC Report 192: recommendations to Notified Bodies • EN 301 893 version 1.4.1 and higher does not allow the user to disable DFS or alter the DFS settings: positive opinions should not be issued on the equipment compliant with earlier versions of the standard! • No issues have been identified with regard to possible shortcomings in the specifications of the DFS mechanism in the current version of EN 301 893 (v1.5.1 and above) • Some cases revealed a non-compliant DFS: Notified Bodies may consider additional laboratory tests to verify the efficiency of the DFS, randomly or from less known manufacturers • The development of additional guidance to manufacturers and Notified Bodies is recommended (see Report’s section 2.6.1)

  16. ECC Report 192: recommendations at the EU level • It could be beneficial to maintain a public list of non-compliant equipment for which EU Member States had initiated a “safeguard clause” in accordance with the R&TTE Directive. Such a list could be used to make European consumer organisations and retailers more aware of the existing problems with non-compliant equipment • Finally, all recommendations and proposed actions to overcome the problem of interference from WAS/RLAN to 5 GHz weather radars should be harmonised in Europe, and ADCO R&TTE/TCAM, R&TTE CA, ECC and ETSI should further work closely in the spirit of cooperation.

  17. Licensed Shared Access (LSA) • LSA is being introduced in the European regulatory framework as an enabler to unlock access to additional frequency bands for mobile broadband and other services under an individual licensed regime while maintaining incumbent users. • It has been developed by the ECC (and also addressed by RSPG within the EU) with the aim of making the dynamic use of spectrum possible, whenever and wherever it is unused by incumbent users.

  18. Licensed Shared Access (LSA) • LSA, as it’s introduced in the draft ECC Report 205, is brining a new dimension into the old, time-proven approach of finding compatibility mechanisms for the introduction of new services in the already used frequency bands, namely: it identifies the possibility to apply smarter tools such as dynamic databases to track and define the opportunities for new services to share with incumbent users which may be limited geographically and in the time over which they need to be protected • The draft ECC Report 205 (developed by the Project Team FM53) was adopted for public consultation in October 2013 and is due to publication in February 2014

  19. Licensed Shared Access (LSA) The ‘standardisation dimension’ of LSA: • The draft ECC Report 205 was devleoped in conjunction with ETSI TC RRS. As well as technical measures to support the implementation of LSA, the report considers an example of LSA functional architechture and identifies interfaces that would require standardisatoin. • Investigations at a European level on the various sharing constraints aim to ensure that corresponding harmonised standards include the necessary tools for implementation of sharing mechanisms required for operation in the band

  20. Licensed Shared Access (LSA): frequency band 2300-2400 MHz • The 2300-2400 MHz was allocated to the mobile service and identified for IMT globally at WRC-2007 • The band is suitable for application of TDD technology and is standardised by 3GPP as LTE Band 40. • The results from ECC Report 172suggested that the introduction of Mobile/Fixed Communications Networks (MFCN) may be possible in this band on a shared basis, and the Project Team FM52 is currently working on the draft ECC Decision for MFCN in the 2300-2400 MHz based on the LSA • Notified Bodies must be prepared for the introduction of LSA

  21. Short Range Devices: pursuing a new regulatory approach • The ECC Newsletter of June 2012 outlined how the ECC is working to improve the efficiency of SRD bands and widen the possibilites for accessing them. This is based on applying a step-by-step evidence-based process for enabling more generic conditions to be applied to wider specturm bands than before, instead of slicing the available frequencies into narrow bandwidth for niche applications • Now ECC is creating a new roadmap which paves the way for a major upgrade of existing 7 MHz+12 MHz (above 863-870 MHz) of UHF spectrum for a wide variety of SRD applications.

  22. Short Range Devices: pursuing a new regulatory approach • Today, the 863-870 MHz band is used extensively by SRD. However, this range is filling up quickly and a lot of new developments are anticipated, as set out in the ECC Report 182 (Survey about the use of the 863-870 MHz band) and by ETSI in a set of System Reference Documents. This includes the need for wider bandwidth applications and the forthcoming introduction of machine mesh networks. • Against this background, nearby frequencies 902-928 MHz are widely used by ISM applications in the American continent, and the 870-876 MHz and 915-921 MHz are seriously underutilized in many European countires (these were prepared for PMR use but very little take-up so far)

  23. Short Range Devices: pursuing a new regulatory approach • ECC Report 200 gives the background and conclusions to a comprehensive set of coexistence studies in the mentioned above underutilised UHF bands in Europe. • ECC Report 200 also describes the use of netowk access points / network relay points forming part of metropolitan area ‘mesh’ networks for utilities or other applications, for example, for data acquisition • The related draft ECC Report 189(prepared by the SRD/MG group and is currently under public consultation) uses these conclusions to define recommended regulatory parameters for SRDs. Upon approval, it is expected to form part of the ECC’s key SRD’s Recommendation 70-03

  24. Short Range Devices: pursuing a new regulatory approach • Thus the ECC studies have resulted in the new band plans for the 870-876 MHz band and 915-921 MHz band, opening up this part of the underused UHF range for SRD applications • This kind of regulatory measures is an example of the ECC’s “soft harmonisation” approach, where existing services remain protected to the extent that national administrations deem it necessary, yet providing the opportunity for the harmonised development of new services in European countries • Notified Bodies shall closely follow the current process of ‘evolution’ of SRD regulations towards enabling more generic conditions in wider spectrum bands.
