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 MHzLow 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• Band to be withdrawn after 2007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

434.20 to 4344.79 MHz• 10 milliwatt; 100% duty cycle; 25 kHz channel spacing

Objective is to:

• Minimise probability of co-channel interference

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 review862 - 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?

Other services in the band include:

• 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• Use of 418 MHz will be withdrawn but recognised need to allow existing equipment to stay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

• But restricted due to limited spectrum harmonisation

• Referred by TCAM to SRD Maintenance Group

“provision of communications to third parties by way of business”

National ConsultationThe three regulatory scenariosNational 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

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
