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
slide5

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  • Band to be withdrawn after 2007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

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
slide9

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

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?

  • Other services in the band include:
    • Military,
    • Outside Broadcast Links,
    • Electronic News Gathering,
    • General SRD’s and
    • Radio LAN’s
slide16

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  • Use of 418 MHz will be withdrawn but recognised need to allow existing equipment to stay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
harmonisation the basics
Harmonisation: the basics

Reaching international agreement on common…….

  • technical standards
  • frequency band limits
  • regulations on use
slide18

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

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
harmonisation current hot topics
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
slide29

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…….

slide30

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.

uk licence exemption regulations
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”

slide32

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

exemption regulations the rationale for proposed changes
Exemption RegulationsThe rationale for proposed changes
  • Market demand for broadband public access

  • Advent of “polite” access technologies
  • Recommendations of 5GHz Advisory Group

(public & private use)

  • 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
