Low Power Radio Devices

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
Reaching international agreement on common…….
• technical standards
• frequency band limits
• regulations concerning use
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
The relevant European forums
Technical Standards

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)
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
European Radiocommunications Office
SRD Maintenance Group
• Maintains ERC Recommendation 70-03
• Proposes band plans
• Develops ERC (ECC) Decisions on SRDs
ERC Recommendation 70-03
Relating 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
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 implementing them all
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)
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
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
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
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
UHF Duty Cycles
Objective is to:
• Minimise probability of co-channel interference
• Maximise use, and improve access to band
Current proposal:
100% 10mW; 25kHz
channels
10% 10mW; no channelling
100% 1mW; no channelling
433.05
434.2

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…….
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.
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?
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 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
(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
Licence Exempt Public Services?
NATIONAL CONSULTATION
• Published 19th October
• Replies by 11th January
CONSULTATION DOCUMENT
Use of Licence-Exempt Spectrum
For Provision of Public Telecommunication
Services
• Available on RA Website
October 2001
The Radiocommunications agency is an Executive Agency of the Department of Trade and Industry.
The Agency's website is located at www.radio.gov.uk
National Consultation
Three regulatory scenarios……….
………..and nine questions.
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
(public & private use of certain bands without licence)
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
LPRA members views on these and any other relevant
issues raised by the proposals will be particularly
welcome!
CLOSING DATE: 11TH JANUARY 2002
