Title: Harmonising Spectrum for Low Power Radio Devices


1
Harmonising SpectrumforLow Power Radio Devices
  • Bob Barron
  • Head of Technology Sectors Unit
  • Radiocommunications Agency

2
Spectrum Harmonisation
  • Advantages of harmonisation for Low Power Radio
  • European harmonisation forums
  • Developing a UK Position
  • Hot issues
  • Proposed Changes to UK Exemption Regulations

3
Harmonisation the basics
Reaching international agreement on common.
  • technical standards
  • frequency band limits
  • regulations concerning use

4
Harmonisation the advantages
  • for industry
  • larger potential product market
  • for users
  • cross border mobility
  • for regulators
  • improved spectrum efficiency

? Particularly appropriate/ advantageous for
de-regulated uncoordinated (ubiquitous) low
power devices
5

Working Group FM Working Group RR Working Group

6
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)
7
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

8
European Radiocommunications Office SRD
Maintenance Group
  • Maintains ERC Recommendation 70-03
  • Proposes band plans
  • Develops ERC (ECC) Decisions on SRDs

9
ERC Recommendation 70-03Relating to the Use of
Short Range Devices
Sets out common spectrum allocations for SRDs
  • Appendix 1 Specific applications technical
    parameters
  • Appendix 2 Relevant ERC Decisions ETSI
    Standards
  • Appendix 3 National Restrictions

ERC Rec 70-03 must be continually maintained
to keep pace with changing requirements and moves
towards increased harmonisation of SRD
allocations regulations
10
ERC (ECC) Decisions on SRDsERC/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 implementing them all

11
RA / LPRA Forum
  • Meets quarterly
  • Briefs LPRA council members on regulations
  • Briefs RA officials on industry requirements
  • Informs RA spectrum policy committee
  • Facilitated by RA2/Technology Sectors Unit
    (TSU)

12
RA Technology Sectors Unit
(a brief commercial interlude!)
  • The RA Business Unit for Low Power Radio
  • Represents SRD interests within the Agency
  • and also responsible for..
  • Processing of all Test Development Licence
    applications
  • All policy issues concerning implementation of
    RTTE Directive

13
RA Technology Sectors Unit
Publications
  • Low Power Devices Information Sheet - RA114
  • Test Development Application Form- RA382
  • RTTE UK SRD Interface Requirements - IR2030

Available today at the RA Stand, or from
www.radio.gov.uk
14
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

15
Harmonisation current hot topics
  • Duty Cycles in 400 MHz SRD bands
  • Ultra Wide Band
  • technical compatibility
  • regulations
  • 862 - 870 MHz Review
  • A new allocation for RFID?
  • Introduction of FHSS
  • narrow / wide band channels

16
UHF Duty Cycles
  • Objective is to
  • Minimise probability of co-channel interference
  • Maximise use, and improve access to band

Current proposal
433.05
434.2
434.79
17

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

18

UWB Study
  • Any UWB regulations need to be decided at
    European level
  • First phase of study defined by CEPT PT SE24
  • Practical compatibility tests carried out by
    RA in support of SE24
  • 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.
19
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?

20
UK Licence Exemption Regulations Statutory
Instrument SI 930 1999
  • All use of radio subject to individual licensing
    (WT Act)
  • Except certain (generally low power) devices
  • Exempt devices must conform to RTTE Directive
  • But Exemption in SI 930 1999 does not apply.
  • to relevant apparatus.. by means of
    which a telecommunication service is provided by
    way of business to another person

i.e. no commercial third party traffic!
21
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
  • (particularly public private use)

N.B. also a recent European Commission Licensing
Committee initiative to determine member states
regulatory policy concerning Public Access
Broadband R-LAN Services
22
Licence Exempt Public Services?
  • NATIONAL CONSULTATION
  • Published 19th October
  • Replies by 11th January
  • Available on RA Website

23
National Consultation
Three regulatory scenarios.
..and nine questions.
24
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
  • (public private use of certain bands without
    licence)

25
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
  • LPRA members views on these and any other
    relevant issues raised by the proposals will be
    particularly welcome!
  • CLOSING DATE 11TH JANUARY 2002
