Where does the BAND C fit in?
  • In the UK during consultation on the future use
    of the 5GHz Band for Broadband Services the
    available Spectrum was designated into three
    sub-bands as follows -
  • BAND A 5150 - 5350 MHz - MOBILE/NOMADIC
    indoor use
  • BAND B 5470 - 5725 MHz - MOBILE/NOMADIC use
  • BAND C 5725 - 5850 MHz - FIXED SERVICES use
  • Bands AB are available for licence exempt use
    now in accordance with requirements stated in
    Interface Requirement 2006.
  • Band C should made available within the next few
    months in accordance with requirements stated in
    Interface Requirement 2007.

Where does the IR2007 fit in?
  • RTTE directive 1999/5/EC was implemented in the
    UK on 8 April 2000.
  • This replaced previous national type approval
    regimes.
  • Introduced conformity assessment procedures
    harmonised set of essential requirements for
    placing equipment on the market.
  • UK also has WT act 1949 that requires equipment
    installed or used to have a licence or licence
    exemption.
  • Article 7.2 of the directive allows member states
    to restrict putting equipment into service for
    reasons related to the avoidance of harmful
    interference.
  • The UK IR 2007 provides this interface between
    the RTTE directive and the licensing of
    equipment to operate in 5.8GHz band without
    causing harmful interference.
  • Article 4.1 of the directive requires that UK
    IR2007 be notified under the normal procedure
    stated in directive 1998/34/EC. (3 month
    standstill process)

5
Where does the VNS fit in?
  • Voluntary National Specification (VNS) VNS 2107
    was published as-
  • a) as no EN has been developed 5.8GHz band.
  • b) 5.8GHz is a non-harmonised band
  • VNS 2107 also had to be notified under the normal
    procedure stated in directive 1998/34/EC. (3
    month standstill process)
  • VNS 2107 is a voluntary specification that
    manufacturers can declare compliance with.
  • Can be used when notifying the member state(UK)
    of equipment that will be placed on the market
    under article 6.4 of RTTE directive.
  • Gives guidance to manufacturers on how to carry
    out equipment compliance testing in order to meet
    the requirements of UK IR2007.
  • Shall be withdrawn when equivalent EN is produced
    by ETSI.

6
EU Notification
  • BOTH THE IR2007 AND THE VNS 2107 ARE NOW APPROVED
    AND PUBLISHED IN THE OFFICIAL JOURNAL OF THE EU.

7
Technical Details (IR2007)
  • Limits decided upon taking into consideration
  • recommendations of WAG sharing group.
  • Ensuring adequate protection of existing services
  • That equipment could be produced to meet the
    limits chosen.
  • UK is first major European market to try to open
    5.8GHz band.
  • Expansion of use to other nations throughout ITU
    Region 1.
  • comments received during the process by other
    nation states.
  • that further sharing analysis will be carried out
    within the WAG and CEPT.
  • Review process in place to take account of future
    analysis results and operational experience.

8
Technical Details (IR2007)
  • Limits included in IR 2007
  • Maximum EIRP 2W
  • PSD not exceeding 100mW/MHz
  • additional restriction on EIRP for the elevation
    angle above the horizontal plane.
  • TPC dynamic range of 19dB relative to 2W EIRP.
  • The frequency range 5795 5815 MHz shall not be
    used. To be reviewed.
  • Dynamic Frequency Selection shall prevent
    co-channel operation in presence of radar
    signals. DFS detection thresholds are
  • - 67dBm for devices with EIRP greater than 1W
  • - 64dBm for devices with EIRP from 200mW to 1W
  • - 62dBm for devices with EIRP less than 200mW
  • 5,10,20 MHz channel plans and corresponding
    spectral power masks are shown in Informative
    annex A. They are not mandatory.

9
Technical Details (VNS 2107)
  • took into consideration
  • Limits and parameters used in IR 2007.
  • EN 301 893 latest version.
  • EN 301 390 latest version.
  • That manufacturers may need additional
    information in order for there equipment to meet
    the requirements of IR2007 on installation.

10
Technical Details (VNS 2107)
  • Tests included and EN referenced in VNS 2107
  • Frequency Range/Nominal Carrier Frequency
    Tolerance (EN 301893)
  • Maximum EIRP (EN 301893) Note maximum EIRP
    increased to 2W from 1W.
  • Dynamic Frequency Selection (EN 301893) Note
    Additional DFS threshold level added to cover
    systems with maximum EIRP greater that 1W.
  • TPC dynamic range (EN 301893) range increased to
    19dB from 6dB.
  • TX and RX spurious emissions taken from EN
    301390.

11
Notification Process to place equipment on the UK
market
  • 5.8GHz Band is a Non-Harmonised Band
  • Need to be notified under procedure stated in
    Article 6.4 of the RTTE directive.
  • SI 2000(730) implements this requirement.
  • Should Notify UK RA at least 4 weeks before
    equipment is intended to placed on market.
  • See www.radio.gov.uk/publication/ra_info/ra368.htm
    or RA information sheet RA368 for more
    information on how to notify.

12
Way ahead for ETSI/CEPT work
  • ETSI Radio Conformance Standard
  • Work Item approved at last ETSI BRAN to write RCT
    for 5.8GHz Band.
  • Rapporteur for RCT is Barry Lewis (Radiant
    Networks)
  • Will be two step approval process.
  • VNS 2107 can be withdrawn if suitable draft is
    sent during first step of approval process.
  • CEPT PT SE 38
  • WAG sharing studies should be taken into
    consideration when submitting SE 38
    contributions.
  • WAG should build on studies already completed.
  • WAG views should be input into process. (could
    appoint liaison between WAG and UK SE38)
  • Any preliminary decisions made by SE38 should be
    discussed in WAG especially if it effects limits
    in IR.
