4 Conclusions from TETRA/SRD Receiver study Receiver performance worse than expected4 to 5 MHz guard band required which is not acceptableUp to 20 MHz of spectrum sterilised418 MHz low power allocation to close
5 The Future of the 418 MHz Low Power Allocation The band MHz is a UK only allocationNo new Notifications accepted after 2002Band to be withdrawn after 2007Existing kit may be used on a non interference basis until the end of its useful life
6 433.05 - 434.79 MHz Band & TETRA TETRA SRD Band 410MHz 430MHz 420MHz 3.05 MHz SeparationMHz
7 433 MHz SRD Band is shared spectrum Military Systems - High Power (Primary service)Amateur Services - High PowerAny Short Range Device 10mW erp433.05MHz433.92MHz434.79MHz
8 433 MHz Band - Duty Cycle Objective is to: Duty cycle proposal Minimise probability of co-channel interferenceMaximise use, and improve access to band433.05434.2434.79100% 1 mW; no channeling100% 10 mW; 25kHz channels10% 10 mW; no channelingDuty cycle proposalto MHz1 milliwatt; 100 % duty cycle; no channel spacing; and10 milliwatt; 10% duty cycle; no channel spacing; andto MHz10 milliwatt; 100% duty cycle; 25 kHz channel spacing
9 450 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 isTETRA could end up near to 458 MHz SRD BandNeed to maintain quality receivers
10 The 863 - 865 MHz Band Wide band cordless audio devices up to 300 kHz Professional radio microphones, up to 200 kHzNarrow band cordless audio devices only in the band to 865 MHz, up to 50 kHz
11 The 868-870 MHz band 868.0-868.6 MHz Power = 25mW Duty Cycle = <1% Duty Cycle = Up to100%General SRDMHzPower = 10mWDuty Cycle = <0.1%MHzMHzPower = 25mWDuty Cycle = <10%= Alarms OnlyMHzPower = tbdDuty Cycle = <10%With access protocol

15 2.4 to 2.5 GHz Band Other services in the band include: Military, Outside Broadcast Links,Electronic News Gathering,General SRD’s andRadio LAN’s
16 ConclusionsDeregulated spectrum used on non interference non protected basisUse of 418 MHz will be withdrawn but recognised need to allow existing equipment to stayImprovement in receiver performance required - selectivityRecognise spectrum as hostile environment and getting worse
17 Harmonisation: the basics Reaching international agreement on common…….technical standardsfrequency band limitsregulations on use
18 Harmonisation: the advantages for industry:larger potential marketfor users:“cross border” mobilityfor regulators:improved spectrum efficiency Particularly appropriate to “de-regulated” low power devices

22 European Radiocommunications Office SRD Maintenance Group Maintains ERC Recommendation 70-03Develops ERC (ECC) Decisions on SRDsProposes band plans
23 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 must be continually maintained to keep pace with changing requirements and moves towards increased harmonisation of SRD allocations & regulations
24 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 SRDsRadio LANsMovement Detection / AlertAlarmsModel ControlInductive applicationsMedical ImplantsWireless AudioDecisions based heavily on ERC Rec 70-03UK Committed to implementation
25 RA / LPRA Forum Facilitated by RA2/Technology Sectors Unit (TSU). Meets quarterly;Briefs LPRA council members on regulations;Briefs RA officials on industry requirements;Facilitated by RA2/Technology Sectors Unit (TSU).

27 The RTTE Directive A harmonised solution to equipment conformity Telecommunication Conformity Assessment & Market Surveillance Committee (TCAM)“Class A” Equipment requires no NotificationProposed extension of Class A to more SRDsBut restricted due to limited spectrum harmonisationReferred by TCAM to SRD Maintenance Group
28 Harmonisation: current “hot topics” Duty Cycles in “433 MHz” SRD bandsMHz ReviewRFIDFHSSnarrow / wide bandUltra Wide Bandtechnical compatibilityregulations
29 Ultra Wide Band A promising innovation Many potential commercial applicationsSolution to spectrum shortage in certain areas?Very low average powerCertainly justifies further consideration.But need to protect existing users…….
30 UWB Study Any UWB regulations need to be decided at European level First phase of study defined by CEPT PT SE24Supporting practical tests carried out by RA RTCGC/I determined, using proprietary UWB, for a range of services:DVB-TT-DABGSMBluetoothSE24 Study Report, including protection distances based on RA test results, to be presented at a proposed ERO sponsored UWB Workshop in March 2002.
31 UK Licence Exemption Regulations All use of radio subject to individual licensing under the Wireless Telegraphy ActExcept certain (generally low power) devicesExempt devices defined in SIExempt devices must conform to RTTE DirectiveBut Exemption Regulations forbid public use, i.e:“provision of communications to third parties by way of business”
33 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 technologiesRecommendations of 5GHz Advisory Group(public & private use)
34 Licence Exempt Public Services? NATIONAL CONSULTATIONPublished 19th OctoberReplies by 11th JanuaryAvailable on RA Website
35 National Consultation Three regulatory scenarios……….………..and nine questions.
36 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
37 National Consultation The nine questions Covering:potential gains & benefitsinterference to existing userscongestionchannel access techniquestypes of commercial services envisagedquality of service in de-regulated spectrumsuitability of specific bandspotential problemstimescales
