MHz Band & TETRA Separation 430MHz 410MHz MHz 1.9 MHz TETRA Mobile TETRA Base
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
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418 MHz Low Power Allocation The band MHz is a UK only allocation No new Notifications accepted after 2002 Band to be withdrawn after 2007 Existing kit may be used on a non interference basis until the end of its useful life
MHz Band & TETRA 410MHz 430MHz 420MHz 3.05 MHz Separation MHz TETRASRD Band
Military Systems - High Power (Primary service) Amateur Services - High Power Any Short Range Device 10mW erp MHz MHz434.79MHz 433 MHz SRD Band is shared spectrum
433 MHz Band - Duty Cycle 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 Objective is to: Minimise probability of co-channel interference Maximise use, and improve access to band % 1 mW; no channeling 100% 10 mW; 25kHz channels 10% 10 mW; no channeling
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
The MHz The 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
The MHz band MHz Power = 10mW Duty Cycle = <0.1% MHz Power = 10mW Duty Cycle = <0.1% MHz Power = 25mW Duty Cycle = <10% = Alarms Only MHz Power = tbd Duty Cycle = <10% With access protocol MHz Power = 25mW Duty Cycle = <1% MHz Power = 25mW Duty Cycle = <0.1% MHz Power = 500mW Duty Cycle = <10% MHz Power = 5mW Duty Cycle = Up to 100% General SRD
New SRD allocations Under discussion for SRDs DSI Phase Cordless Audio Applications TETRA Harmonised Band for SRDs CT2 870 MHz MHz
MHz review 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? Borne out of ERO Detailed Spectrum Investigation Phase III……..
RFID at 2.4 GHz 4 Watts EIRP (Indoor Limit) mW Non-specific SRD 500 mW EIRP (Outdoor Limit) GHz
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
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 technical standards frequency band limits regulations on use Reaching international agreement on common…….
Harmonisation: the advantages for users: –“cross border” mobility for regulators: –improved spectrum efficiency Particularly appropriate to “de-regulated” low power devices for industry: –larger potential market

CEPT Working Groups Radio RegulatoryWGRR Frequency ManagementWGFM Spectrum EngineeringWGSE Conference PreparatoryCPG (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)
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 Develops ERC (ECC) Decisions on SRDs Proposes band plans
ERC Recommendation Relating to the Use of Short Range Devices 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 Sets out common spectrum allocations for SRDs:
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 UK Committed to implementation
RA / LPRA Forum Meets quarterly; Briefs LPRA council members on regulations; Briefs RA officials on industry requirements; Facilitated by RA2/Technology Sectors Unit (TSU).
Technology Sectors Unit Short Range Devices Information Sheet - RA114 Test & Development Application Form RA 382 RTTE UK SRD Interface Requirements - IR2030 Publications Available today at RA Stand, or from
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 “433 MHz” SRD bands MHz Review –RFID –FHSS –narrow / wide band Ultra Wide Band –technical compatibility –regulations
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…….
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 UWB Study SE24 Study Report, including protection distances based on RA test results, to be presented at a proposed ERO sponsored UWB Workshop in March C/I determined, using proprietary UWB, for a range of services: DVB-T T-DAB GSM Bluetooth
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”
The Statutory Instruments The Wireless Telegraphy (Exemption) Regulations 1999 No. 930 The Wireless Telegraphy (Exemption) (Amendment) Regulations 2000 No The Wireless Telegraphy (Exemption) (Amendment) Regulations 2001 No. 730
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)
Licence Exempt Public Services? NATIONAL CONSULTATION Published 19th October Replies by 11th January Available on RA Website
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
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 National Consultation The nine questions
