  3. 417.9 - 418.1 MHz 425 430MHz 420 410MHz 415 Separation 1.9 MHz 417.9 - 418.1 MHz Band& TETRA TETRA Mobile TETRA Base

  4. Conclusions from TETRA/SRD Receiver study • Receiver performance worse than expected • 4 to 5 MHz guard band required which is not acceptable • Up to 20 MHz of spectrum sterilised • 418 MHz low power allocation to close

  5. The Future of the 418 MHzLow Power Allocation • The band 417.9 - 418.1 MHz is a UK only allocation • No new Notifications accepted after 2002 • Band to be withdrawn after 2007 • Existing kit may be used on a non interference basis until the end of its useful life

  6. 433.05 - 434.79MHz 410MHz 420MHz 430MHz 3.05 MHz Separation 433.05 - 434.79 MHz Band& TETRA TETRA SRD Band

  7. 433 MHz SRD Band is shared spectrum Military Systems - High Power (Primary service) Amateur Services - High Power Any Short Range Device 10mW erp 433.05MHz 434.79MHz 433.92MHz

  8. 100% 10 mW; 25kHz channels 10% 10 mW; no channeling 100% 1 mW; no channeling 433.05 434.2 434.79 433 MHz Band - Duty Cycle • Objective is to: • Minimise probability of co-channel interference • Maximise use, and improve access to band • Duty cycle proposal 433.05 to 434.79 MHz • 1 milliwatt; 100 % duty cycle; no channel spacing; and • 10 milliwatt; 10% duty cycle; no channel spacing; and 434.20 to 4344.79 MHz • 10 milliwatt; 100% duty cycle; 25 kHz channel spacing

  9. 450 to 470 MHz Band • Re-alignment of the UHF band with Europe • Currently, it is planned to leave the 458 MHz SRD Band as it is • TETRA could end up near to 458 MHz SRD Band • Need to maintain quality receivers

  10. The 863 - 865 MHz Band Wide band cordless audio devices up to 300 kHz Professional radio microphones, up to 200 kHz Narrow band cordless audio devices only in the band 864.8 to 865 MHz, up to 50 kHz

  11. 868.0-868.6 MHz Power = 25mW Duty Cycle = <1% 868.7 - 869.2 MHz Power = 25mW Duty Cycle = <0.1% 869.3 - 869.4 MHz Power = tbd Duty Cycle = <10% 869.65 - 8697 MHz Power = 25mW Duty Cycle = <10% 868.6 - 868.7 MHz Power = 10mW Duty Cycle = <0.1% 869.4 - 869.65 MHz Power = 500mW Duty Cycle = <10% 869.7 - 870.0 MHz Power = 5mW Duty Cycle = Up to 100% 869.2 - 869.3MHz Power = 10mW Duty Cycle = <0.1% General SRD With access protocol = Alarms Only The 868-870 MHz band

  12. New SRD allocations Under discussion for SRDs DSI Phase    Harmonised Band for SRDs Cordless Audio Applications TETRA CT2 862MHz 863 864 865 868 870MHz

  13. 862 - 870 MHz review Borne out of ERO Detailed Spectrum Investigation Phase III…….. • Consultation on future industry requirements • bandwidths • power levels • duty cycles • access technologies • Main area of consideration is 865 - 868 MHz (ex CT2) • Need for compatibility studies to verify any bandplans: • introduction of spread spectrum • possible RFID allocation • Networks & Third Party Traffic?

  14. RFID at 2.4 GHz 4 Watts EIRP (Indoor Limit) 500 mW EIRP (Outdoor Limit) 10 mW Non-specific SRD 2.4 2.445 2.483 2.455 GHz

  15. 2.4 to 2.5 GHz Band • Other services in the band include: • Military, • Outside Broadcast Links, • Electronic News Gathering, • General SRD’s and • Radio LAN’s

  16. Conclusions • Deregulated spectrum used on non interference non protected basis • Use of 418 MHz will be withdrawn but recognised need to allow existing equipment to stay • Improvement in receiver performance required - selectivity • Recognise spectrum as hostile environment and getting worse

  17. Harmonisation: the basics Reaching international agreement on common……. • technical standards • frequency band limits • regulations on use

  18. Harmonisation: the advantages • for industry: • larger potential market • for users: • “cross border” mobility • for regulators: • improved spectrum efficiency  Particularly appropriate to “de-regulated” low power devices

  19. The relevant European forums Technical Standards Spectrum Management TC ERM Task Groups TG 11- Wide Band Data Systems TG 17 - Broadcasting and Ancillaries TG 28 - Generic SRD* TG 29 - Road Transport & Telematics* TG 30- Wireless Medical Devices* TG 31- Ultra Wide Band & Radar* *Formerly RP08 Working Group FM Working Group RR Working Group SE Project Team SE24 SRD Maintenance Group

  20. CEPT Working Groups • Radio Regulatory WGRR • Frequency Management WGFM • Spectrum Engineering WGSE • Conference Preparatory CPG (WRC2003) In addition, there are a number of Project teams associated with, and reporting to, the Working Groups. These deal with specific issues (e.g. WGSE PT SE24 for SRDs)

  21. CEPT Project Team SE24 Reports to CEPT Working Group Spectrum Engineering • PT membership includes administrations and industry • Supports WG FM activities on SRDs • Undertakes SRD compatibility studies • Commissions any necessary practical work • Works closely with the ERO SRD Maintenance Group

  22. European Radiocommunications OfficeSRD Maintenance Group • Maintains ERC Recommendation 70-03 • Develops ERC (ECC) Decisions on SRDs • Proposes band plans

  23. ERC Recommendation 70-03Relating to the Use of Short Range Devices Sets out common spectrum allocations for SRDs: • Specific applications & technical parameters (appendix 1) • Relevant ERC Decisions & ETSI Standards (appendix 2) • National Restrictions (appendix 3) ERC Rec 70-03 must be continually maintained to keep pace with changing requirements and moves towards increased harmonisation of SRD allocations & regulations

  24. ERC (ECC) Decisions on SRDsERC/DEC (01)01 to ERC/DEC(01)18 inclusive • Non specific SRDs • Radio LANs • Movement Detection / Alert • Alarms • Model Control • Inductive applications • Medical Implants • Wireless Audio Total 18 new Decisions agreed in 2001, covering: • Decisions based heavily on ERC Rec 70-03 • UK Committed to implementation

  25. RA / LPRA Forum • Meets quarterly; • Briefs LPRA council members on regulations; • Briefs RA officials on industry requirements; • Facilitated by RA2/Technology Sectors Unit (TSU).

  26. Technology Sectors Unit Publications • Short Range Devices Information Sheet - RA114 • Test & Development Application Form RA 382 • RTTE UK SRD Interface Requirements - IR2030 Available today at RA Stand, or from www.radio.gov.uk

  27. The RTTE DirectiveA harmonised solution to equipment conformity Telecommunication Conformity Assessment & Market Surveillance Committee (TCAM) • “Class A” Equipment requires no Notification • Proposed extension of Class A to more SRDs • But restricted due to limited spectrum harmonisation • Referred by TCAM to SRD Maintenance Group

  28. Harmonisation: current “hot topics” • Duty Cycles in “433 MHz” SRD bands • 862 - 870 MHz Review • RFID • FHSS • narrow / wide band • Ultra Wide Band • technical compatibility • regulations

  29. Ultra Wide Band • A promising innovation • Many potential commercial applications • Solution to spectrum shortage in certain areas? • Very low average power • Certainly justifies further consideration. But need to protect existing users…….

  30. UWB Study • Any UWB regulations need to be decided at European level • First phase of study defined by CEPT PT SE24 • Supporting practical tests carried out by RA RTCG • C/I determined, using proprietary UWB, for a range of services: • DVB-T • T-DAB • GSM • Bluetooth SE24 Study Report, including protection distances based on RA test results, to be presented at a proposed ERO sponsored UWB Workshop in March 2002.

  31. UK Licence Exemption Regulations • All use of radio subject to individual licensing under the Wireless Telegraphy Act • Except certain (generally low power) devices • Exempt devices defined in SI 930 1999 • Exempt devices must conform to RTTE Directive • But Exemption Regulations forbid public use, i.e: “provision of communications to third parties by way of business”

  32. The Statutory Instruments The Wireless Telegraphy (Exemption) Regulations 1999 No. 930 The Wireless Telegraphy (Exemption) (Amendment) Regulations 2000 No. 1012 The Wireless Telegraphy (Exemption) (Amendment) Regulations 2001 No. 730

  33. Exemption RegulationsThe rationale for proposed changes • Market demand for broadband public access (particularly in “hot spots” such as airport lounges) • Advent of “polite” access technologies • Recommendations of 5GHz Advisory Group (public & private use)

  34. Licence Exempt Public Services? NATIONAL CONSULTATION • Published 19th October • Replies by 11th January • Available on RA Website

  35. National Consultation Three regulatory scenarios………. ………..and nine questions.

  36. National ConsultationThe three regulatory scenarios • Maintain “status quo” (no public services without a licence) • Some public use but with a light regulatory regime (e.g. indoor use only?) • Licence Exempt Public Services

  37. National ConsultationThe nine questions Covering: • potential gains & benefits • interference to existing users • congestion • channel access techniques • types of commercial services envisaged • quality of service in de-regulated spectrum • suitability of specific bands • potential problems • timescales
