The RA Business Unit for Low Power Radio but also responsible for…….. Space and Scientific Research Research & Development Processing of all Test & Development Licence applications Conformity Assessment All policy issues concerning implementation of RTTE Directive Notifications

3 417.9 - 418.1 MHz Band & TETRA 417.9 - 418.1 MHz Separation 430MHz
420 415 425 MHz 1.9 MHz 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 MHz Low Power Allocation
The band MHz is a UK only allocation No new Notifications accepted after 2002 Band to be withdrawn after 2007 Existing kit may be used on a non interference basis until the end of its useful life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 - 434.79 MHz Band & TETRA TETRA SRD Band 410MHz 430MHz 420MHz
3.05 MHz Separation MHz

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 433.92MHz 434.79MHz

8 433 MHz Band - Duty Cycle Objective is to: Duty cycle proposal
Minimise probability of co-channel interference Maximise use, and improve access to band 433.05 434.2 434.79 100% 1 mW; no channeling 100% 10 mW; 25kHz channels 10% 10 mW; no channeling Duty cycle proposal to MHz 1 milliwatt; 100 % duty cycle; no channel spacing; and 10 milliwatt; 10% duty cycle; no channel spacing; and to 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 to 865 MHz, up to 50 kHz

11 The 868-870 MHz band 868.0-868.6 MHz Power = 25mW Duty Cycle = <1%
Duty Cycle = Up to 100% General SRD MHz Power = 10mW Duty Cycle = <0.1% MHz MHz Power = 25mW Duty Cycle = <10% = Alarms Only MHz Power = tbd Duty Cycle = <10% With access protocol

12 Under discussion for SRDs DSI Phase   
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 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 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 500 mW EIRP 10 mW Non-specific SRD GHz
(Indoor Limit) 500 mW EIRP (Outdoor Limit) 10 mW Non-specific SRD 2.4 2.445 2.455 2.483 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 These deal with specific issues (e.g. WGSE PT SE24 for SRDs)
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 Office SRD Maintenance Group
Maintains ERC Recommendation 70-03 Develops ERC (ECC) Decisions on SRDs Proposes band plans

23 ERC Recommendation 70-03 Relating 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 must be continually maintained to keep pace with changing requirements and moves towards increased harmonisation of SRD allocations & regulations

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

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

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

27 The RTTE Directive A 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 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 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 Regulations The 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 Consultation The 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 Consultation The 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
