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

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

Harmonisation: the advantages
• for users:
“cross border” mobility
• for regulators: improved spectrum efficiency
Particularly appropriate/ advantageous for “de-regulated” uncoordinated (ubiquitous) low power devices
• for industry: larger potential product market

![Page 9: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/9.jpg)
ERC Recommendation 70-03Relating to the Use of Short Range Devices
• Appendix 1: Specific applications & technical parameters
• Appendix 2: Relevant ERC Decisions & ETSI Standards

harmonisation of SRD allocations & regulations
Sets out common spectrum allocations for SRDs:

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
![Page 15: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/15.jpg)
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
![Page 16: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/16.jpg)
UHF Duty Cycles

10% 10mW; no channelling
100% 10mW; 25kHzchannels
433.05 434.2 434.79
Objective is to:
• Minimise probability of co-channel interference
• Maximise use, and improve access to band
Current proposal:
![Page 17: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/17.jpg)
• 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…….
![Page 18: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/18.jpg)
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-TT-DABGSMBluetooth
SE24 Study Report, including protection distances based on
RA test results, to be presented at a proposed ERO sponsored UWB Workshop in March 2002.

862 - 870 MHz review
• 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?

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!

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

National Consultation
Three regulatory scenarios……….
………..and nine questions.
![Page 24: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/24.jpg)
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)
![Page 25: Harmonising Spectrum for Low Power Radio Devices Bob Barron Head of Technology Sectors Unit Radiocommunications Agency](https://reader035.vdocuments.site/reader035/viewer/2022070307/551b2efc550346dd1a8b4d0f/html5/thumbnails/25.jpg)
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
