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Power Allocation The band 417.9 - 418.1 MHz is a UK only allocation No new Notifications accepted after 2002 Band to be withdrawn after 2007 Existing kit may be used on a non interference basis until the end of its useful life

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

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?

RFID at 2.4 GHz 4 Watts EIRP 500 mW EIRP 10 mW Non-specific SRD GHz (Indoor Limit) 500 mW EIRP (Outdoor Limit) 10 mW Non-specific SRD 2.4 2.445 2.455 2.483 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Conclusions Deregulated spectrum used on non interference non protected basis Use of 418 MHz will be withdrawn but recognised need to allow existing equipment to stay Improvement in receiver performance required - selectivity Recognise spectrum as hostile environment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 Reaching international agreement on common……. technical standards frequency band limits regulations on use

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

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

ERC Recommendation 70-03 Relating to the Use of Short Range Devices Sets out common spectrum allocations for SRDs: Specific applications & technical parameters (appendix 1) Relevant ERC Decisions & ETSI Standards (appendix 2) National Restrictions (appendix 3) 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 implementation

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 862 - 870 MHz Review RFID FHSS narrow / wide band Ultra Wide Band technical compatibility regulations

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…….

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 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”

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 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

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
