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

5. 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Band to be withdrawn after 2007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

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 is
TETRA could end up near to 458 MHz SRD Band
Need to maintain quality receivers

13. 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 MHz (ex CT2)
Need for compatibility studies to verify any bandplans:
introduction of spread spectrum
possible RFID allocation
Networks & Third Party Traffic?

15. 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

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Use of 418 MHz will be withdrawn but recognised need to allow existing equipment to stay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

17. Harmonisation: the basics
Reaching international agreement on common…….
technical standards
frequency band limits
regulations on use

18. 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

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

Movement Detection / Alert
Alarms
Model Control
Inductive applications
Medical Implants

27. 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

28. Harmonisation: current “hot topics”

FHSS
narrow / wide band
Ultra Wide Band
technical compatibility

29. 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…….

30. UWB Study Any UWB regulations need to be decided at European level

31. 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 Wireless Telegraphy (Exemption) (Amendment) Regulations 2000 No. 1012
The Wireless Telegraphy (Exemption) (Amendment) Regulations 2001 No. 730

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 technologies
Recommendations of 5GHz Advisory Group
(public & private use)

34. Licence Exempt Public Services?

………..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 & benefits
interference to existing users
congestion
channel access techniques
types of commercial services envisaged
