2 The impact of re-configurable radio networks on spectrum management Overview Regulatory Background/Review R&TTE Directive TCAM Group on SDR Current Status/activities International Environment for Frequency Regulation Future perspective 10/13/2003 Ver.1 2

3 Background The R&TTE Directive* *DIRECTIVE 1999/5/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity 10/13/2003 Ver.1 3

4 The R&TTE Directive* The R&TTE Directive covers the regulatory framework for the placing on the market free movement putting into service of radio equipment and telecommunications terminal equipment in the Community. *Radio and Telecommunications Terminal Equipment (1999/5/EG) 10/13/2003 Ver.1 4

5 The R&TTE Directive What does this imply for radio equipment? Type approval with certificate belongs to the past Declaration of conformity by the manufacturer with the essential requirements of the R&TTE is required in the future for the radio equipment. 10/13/2003 Ver.1 5

6 The R&TTE Directive The basic essential requirements of the R&TTE are defined in Articles 3.1 and 3.2 These are the protection of the health and the safety of the user the protection requirements with respect to electromagnetic compatibility that radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communication and orbital resources so as to avoid harmful interference 10/13/2003 Ver.1 6

7 The R&TTE Directive The European Commission may decide that for particular apparatus additional essential requirement (Article 3.3) may apply. These are interworking via networks not harming the network 10/13/2003 Ver.1 7

8 The R&TTE Directive Incorporation of safeguards to ensure that the personal data and privacy of the user and of the subscriber are protected supporting certain features ensuring avoidance of fraud supporting certain features ensuring access to emergency services supporting certain features in to order to facilitate its use by users with a disability. 10/13/2003 Ver.1 8

9 The R&TTE Directive Until now, article 3.3 requirements have been applied to Navtex* Maritime emergency position indicating radio beacons Radiotelephone transmitters and receivers for the maritime mobile service operating in VHF bands Avalanche beacons;transmitter-receiver systems VHF radiotelephone equipment for general communications and associated equipment for Class D digital selective calling (DSC) Question: Do we need article 3.3 requirements for re-configurable Systems? * Narrow-band direct-printing telegraph equipment for receiving meteorological or navigational information 10/13/2003 Ver.1 9

10 The R&TTE Directive For compliance of the radio equipment with the essential requirement of the R&TTE, the manufacturer has two possibilities: 1.To use a Harmonised Standard (if available) for his declaration; or 2.To consult a Notified Body and ask him which are the relevant essential requirements for his radio equipment 10/13/2003 Ver.1 10

11 The R&TTE Directive A harmonised standard giving presumption of conformity with the essential requirements of the R&TTE Directive It has to be published in the Official Journal of the Community Question: Do we need a harmonised standard for reconfigurable Systems to declare compliance with the R&TTE-Directive? 10/13/2003 Ver.1 11

12 The R&TTE Directive ETSI Groups(examples) developing harmonised standards: TFES(Task Force for ERM and MSG for Harmonised Standards for IMT-2000) BRAN(Broadband Radio Access Networks) EP-DECT(Digital Enhanced Cordless Telecommunications) ERM(EMC and Radio Spectrum Matters) SES(Satellite Earth Stations & Systems) TETRA(Terrestrial Trunked Radio) 10/13/2003 Ver.1 12

13 The R&TTE Directive Placing on the market If the radio equipment complies with the appropriate essential requirements identified in Article 3 for its intended purpose it shall not be subject to further national provisions in respect of placing on the market. 10/13/2003 Ver.1 13

14 The R&TTE Directive Obligations for operators (Article 4.2) A operator should publish accurate and adequate technical specifications of his public interfaces The specifications shall be in sufficient detail to permit the design of equipment for this interface 10/13/2003 Ver.1 14

15 The R&TTE Directive According to Article 7(3) of the Directive, Member States must ensure that operators of public telecommunications networks do not refuse to connect telecommunications terminal equipment to appropriate interfaces on technical grounds where the equipment complies with the applicable essential requirements of Article 3. 10/13/2003 Ver.1 15

16 The R&TTE Directive Regulation of the use of radio equipment 10/13/2003 Ver.1 16

17 The R&TTE Directive Regulation of the use of radio equipment Member States/national authority may restrict the putting into service of radio equipment only for reasons related to the effective and appropriate use of the radio spectrum so as to avoid harmful interference or matters relating to public health. 10/13/2003 Ver.1 17

18 The R&TTE Directive Regulation of the use of radio equipment If the radio equipment is operating in frequencies whose use is harmonised there are no additional requirements if the radio equipment complies with the appropriate essential requirements identified in Article 3 (e.g. complying with the appropriate HS) 10/13/2003 Ver.1 18

19 The R&TTE Directive Regulation of the use of radio equipment If the radio equipment is operating in frequency bands whose use is not harmonised the equipment has to comply with national specifications 10/13/2003 Ver.1 19

20 The R&TTE Directive Radio equipment using frequency bands whose use is not harmonised Radio equipment using frequency bands whose use is not harmonised throughout the Community, the manufacturer shall notify the national authority responsible in the relevant Member State for spectrum management of the intention to place such equipment on its national market four weeks in advance of the start of placing it on the market. The Manufacture shall provide information about the radio characteristics of the equipment (in particular frequency bands, channel spacing, type of modulation and RF-power) 10/13/2003 Ver.1 20

21 TCAM Group on SDR TCAM Group on SDR (TGS): Objective: The objective of TGS is to have the regulatory aspects of SDR with respect to the R&TTE Directive examined by the member states and to draft relevant proposals for submission to TCAM. The Group is chaired by Germany. The first meeting took place on 31 January 2002 at RegTP. 10/13/2003 Ver.1 21

22 TCAM Group on SDR TCAM Group on SDR (TGS): So far, four meetings of the group have taken place. Up to now there is no common view by the member states within TGS on the regulatory requirements for SDR under the R&TTE Directive 10/13/2003 Ver.1 22

23 TCAM Group on SDR TCAM Group on SDR (TGS): Therefore it was agreed within TGS and with the European Commission to publish a Questionnaire Impact of SDR on the R&TTE Directive, elaborated within TGS, on the Internet page of the European commission ( The closing date for comments was 30 th September /13/2003 Ver.1 23

24 Current Status/activities Questionnaire Impact of SDR on the R&TTE Directive ISSUES CONTAINED IN this questionnaire It should be assessed whether SDR has the potential to request new interpretations of the Directive s current text, or simply a revision of it. The prime goal of the questionnaire is to help Member States, TCAM, and the Commission services, to figure out WHEN, AT THE EARLIEST, some kind of Software Defined Radio equipment, might be proposed on the EU market and if it could possibly put the Directive at fault. Regulators have an interest in establishing clear responsibilities in case of non-compliance. The potential advantages of flexible hardware shouldn t lead to illegal use. 10/13/2003 Ver.1 24

25 Current Status/activities Public SDR consultation in Germany with regard to the R&TTE-Directive 10/13/2003 Ver.1 25

26 Current Status/activities Public SDR consultation took place in Germany A public consultation took place in Germany Started: 5 February 2003 Ended: 4 April 2003 Within the framework of the TGS questionnaire the results of the national German consultation will be presented to TGS for discussion. 10/13/2003 Ver.1 26

27 Current Status/activities Public SDR consultation took place in Germany First results of the comments of the national German Consultation 10/13/2003 Ver.1 27

28 Current Status/activities Public SDR consultation took place in Germany First results of the comments of the national German Consultation were: Principally there are no restrictions with regard to the performance of the technical feasibility by means of software. It is a question of time and money. In the near future the estimation is for a vertical SDR Market. SDR will probably be used for handset updates, bug fixing, WLAN and for IMT 2000 base stations 10/13/2003 Ver.1 28

29 Current Status/activities Public SDR consultation took place in Germany First results of the comments of the national German Consultation were : To establish a horizontal market, additions have to be made to the R&TTE Directive. One requirement could be to require from the manufacturer to publish the internal interface of the equipment. 10/13/2003 Ver.1 29

30 Current Status/activities Public SDR consultation took place in Germany First results of the comments of the national German Consultation were : Time horizon for the implementation of SDR is: For equipment for the Radio Infrastructure at the introduction of IMT 2000 base stations In the licence-exempt frequency band very soon - (e.g. WLAN) In in the car industry. Here, broadcast standards for the car will be combined with mobile standards based on SDR. 10/13/2003 Ver.1 30

31 Future perspective Possible areas of regulation An early standardisation of SDR systems seems to be essential in particular for the definition of security mechanisms, download mechanism, authentication of software modules etc. and open interfaces. In a vertical market it should be ensured that the equipment only accepts authorised software. For the time being for software to be able to change the radio parameters of the equipment only a vertical market should be possible. 10/13/2003 Ver.1 31

32 Future perspective Possible areas of regulation For the establishment of a horizontal market regulatory guidelines are essential. It could also be possible in a horizontal market to limit the use of software to applications and services but exclude it from changing the radio parameters. To verify the source of the software download. History of the software changes (market surveillance) Without accesses for the user. The user should also not be permitted to deled this history information. Security aspects Changes in the equipment behaviour should only be possible with the approval of the user 10/13/2003 Ver.1 32

33 Future perspective TCAM The results of the national German consultation will be presented to TGS for discussion. (2003) On the basis of the results of the consultation TGS will draw up a joint report for submission and information to TCAM, including recommendations with regard to the regulatory aspects of SDR under the R&TTE Directive.
