Rapporteur: Mrs. Shayla Taylor (USA)
1.2, 1.20, 1.21
 1.2: Allocations and related regulatory issues for EESS (passive),
SRS (passive) and Meteo-Sat in 18.1 – 18.4 GHz, 10.6 – 10.68 GHz
and 36 – 37 GHz
 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz, 23.6 –
24 GHz, 31.3 – 31.5 GHz, 50.2 – 50.4 GHz) from unwanted
emissions of active services
 1.21: Compatibility between RA and active space services (bands
referred to in Res740) in order to review and update the threshold
levels used for consultation (Annex to Res739)
AI 1.2: Allocations and related regulatory issues for EESS
(passive), SRS (passive) and MetSat in 18.1–18.4 GHz,
10.6–10.68 GHz and 36–37 GHz (1)
Current results of studies (18.1-18.4 GHz):
• the addition of 100 MHz seems feasible under certain
conditions (but compatibility between MetSat and NGSO
FSS not studied);
• proposes additional allocation, either 18.0-18.1 or 18.318.4 GHz;
• indication that 18.0-18.1 GHz option may impose minor
constrains on MetSat orbital positions due to operation of
BSS feeder-links of networks belonging to Regions 1 and 3
BSS Plans/Lists (Appendix 30A)
AI 1.2: Allocations and related regulatory issues for EESS
(passive), SRS (passive) and MetSat in 18.1–18.4 GHz,
10.6–10.68 GHz and 36–37 GHz (2)
Current results of studies (10.6-10.68 GHz and
36-37 GHz):
• interference from FS in 10.6-10.68 GHz band may
exceed limits for EESS sensors by ~17 dB;
mitigation therefore necessary;
• preliminary sharing criteria proposed for 36-37
GHz band, but not to be applied to terrestrial
systems brought into use before WRC-07
AI 1.20: Protection of EESS (passive) (bands 1400 – 1427 MHz,
23.6 – 24, 31.3 – 31.5, 50.2 – 50.4 GHz) from unwanted
emissions of active services
Current results of studies:
• TG 1/9 revising Rec. ITU-R SM.1633, which should
be used as a basis for developing EESS protection
criteria;
• proposed to include unwanted emission power
[limit /level] in RR; sensors protected but some
limitation on future active systems;
• still at a preliminary stage.
AI 1.21: Compatibility between RA and active space
services (Res.740) in order to review and update threshold
levels used for consultation (Annex to Res.739)
Current results of studies:
• proposed PFD threshold levels for RAS protection
from interference from different services;
• 3 methods are under consideration:
 1st –add approved thresholds in Res.739 and apply
them (RAS protected, but more work for ADMs
due consultation);
 2nd similar to 1st but RNSS is not covered (no
burden for ADMs but RAS may not be protected in
1559-1610 MHz);
 3rd no incorporation of thresholds (TBD).

 1.3: Consider upgrading of RLS in 9000 – 9200 MHz and 9300 – 9500
MHz to primary status and extending by 200 MHz the allocation to
the EESS (active) and SRS (active)
 1.4: Frequency related matters for IMT-2000 and systems beyond
IMT-2000
 1.5: Additional spectrum for wideband aeronautical telemetry /
telecommand in 3 – 16 GHz

between 108 MHz and 6 GHz
