1.2 to consider allocations and regulatory issues related to the Earth
exploration-satellite (passive) service, space research (passive)
service and the meteorological satellite service in accordance with
Resolutions **746** **(WRC‑03)** and **742** **(WRC‑03)**

Introduction

# 1 Resolution 746 (WRC-03) 

resolves

"1 to invite ITU-R to conduct sharing analyses between geostationary
meteorological satellites operating in the space-to-Earth direction and
the fixed, fixed-satellite and mobile services in the band 18-18.4 GHz
to define appropriate sharing criteria with a view to extending the
current 18.1-18.3 GHz geostationary meteorological satellites allocation
in the space-to-Earth direction to 300 MHz of contiguous spectrum;"

An expansion of the current meteorological-satellite service (MetSat)
allocation is desirable as the next-generation geostationary MetSat
systems are expected to have bandwidth requirements up to 300 MHz. A
primary allocation to the geostationary MetSat (space-to-Earth) exists
already in the band 18.1-18.3 GHz based on RR No. 5.519.

In order to secure the necessary frequency spectrum for the
next-generation geostationary meteorological satellite (MetSat) systems,
APT supports extension of the existing 18 GHz MetSat allocation by 100
MHz. However, existing services (FS, FSS including feeder-links for the
BSS Plan (Regions 1 and 3) and MS) must be protected from harmful
interference due to the possible extension of the MetSat allocation.
Additionally, extending the ±8° coordination arc currently applicable to
FSS networks in this band, to the MetSat in the band 18.1-18.4 GHz is
appropriate. This could be accomplished through appropriate
modifications to Table 5-1 in RR Appendix 5.

# 2 Resolution 742 (WRC-03)

resolves

1 "to invite ITU-R to conduct sharing studies between the passive
services and the fixed and mobile services in the band 36-37 GHz in
order to define appropriate sharing criteria;"

This agenda item addresses sharing between the Earth
exploration-satellite service (passive) and the space research service
(passive), and the fixed service and the mobile service in the band
36-37 GHz. Sharing scenarios have been analysed and mitigation
techniques have been identified, leading to possible technical limits to
allow sharing.

With respect to the sharing criteria between active and passive services
in the bands 36-37 GHz, the protection of passive services should not
place additional undue constraints on other allocated services. Sharing
criteria should be appropriately defined based on the results of the
ITU-R studies. Single-entry emission limits taking into account the
results of the compatibility analysis and the sharing criteria are
proposed to be included in the RR. These limits would be non-retroactive
for the terrestrial active systems notified or brought into use before a
date \[to be decided by WRC‑07\]. Possible modifications to the Radio
Regulations are shown below. Resolution 742 (WRC-03) should be deleted.

**5.519** *Additional allocation:  *the band 18.1-18.4 GHz is also
allocated to the meteorological-satellite service (space-to-Earth) on a
primary basis. Its use is limited to geostationary satellites and shall
be in accordance with the provisions of Article **21**, Table **21-4**.

**Reasons:** APT supports the extension in the upper part.

**ADD** ASP/41A2/14

**5.A12** For sharing of the band 36-37 GHz between the Earth
exploration-satellite (passive) service and the fixed and mobile
services, Resolution **\[ASP/AI1.2/1-36 GHz SHARING\] (WRC‑07)** shall
apply.      (WRC-07)

**Reasons:** Passive sensor measurements in this band are currently
being used to determine rain, snow, ocean ice, cloud liquid and water
vapour properties for use in numerical weather prediction models and
other scientific applications including studies the hydrological cycle
or global water circulation. Currently, this band is lightly used
worldwide by the fixed and mobile services. It is necessary to establish
an appropriate operational environment to protect the future use of
Earth exploration-satellite (passive) and space research (passive)
services in this band without imposing undue constraints on the fixed
and mobile services.

**ADD** ASP/41A2/15

RESOLUTION \[ASP/AI1.2/1-36 GHz Sharing\] (WRC-07)

Sharing criteria applied to the use of the frequency band 36-37 GHz

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that the frequency band 36-37 GHz is allocated to the Earth
exploration-satellite service (EESS) (passive) and to the space research
service (SRS) (passive) on a primary basis;

*b)* that the frequency band 36-37 GHz is allocated to the fixed service
and to the mobile service on a primary basis;

*c)* that the EESS (passive) interference levels are contained in
Recommendation ITU‑R RS.1029;

*d)* that the band 36-37 GHz is not available for high-density
applications in the fixed service (see No. **5.547**);

*e)* that the band 36-37 GHz is of primary interest to the EESS
(passive) to measure rain, snow, ocean ice, cloud liquid and water
vapour;

*f)* that this frequency band is used by passive sensors to study
natural phenomena producing radio emissions at frequencies fixed by the
laws of nature, and therefore shifting frequency to avoid or mitigate
interference problems may not be possible;

*g)* that the EESS (passive) operating in the band 36-37 GHz may suffer
from interference from the emissions of systems of active services;

*h)* that studies have concluded that appropriate sharing criteria
applicable to both passive and active services would reduce this
interference to a level that would permit passive sensors to operate
successfully in this band, while allowing continuing operation of active
services in the same band;

*i)* that Recommendation ITU-R RS.\[10/36 GHz MITIGATE\] provides the
technical and operational characteristics for passive sensors in the
Earth exploration-satellite (passive) service to facilitate sharing of
the 36-37 GHz bands with the fixed and mobile services;

*j)* that Recommendation ITU-R F.\[10/36 GHz MITIGATE\] provides the
technical and operational characteristics for the stations of fixed
service to facilitate sharing of the 36-37 GHz bands with the Earth
exploration-satellite (passive) service,

resolves

that, in order to facilitate sharing between active and passive services
in the band 36-37 GHz, stations in the fixed and mobile services brought
into use on or after the date of entry into force of the WRC-07 Final
Acts shall comply with the sharing criteria contained in Tables 1 and 2
of Annex 1.

ANNEX 1 to resolution \[asp/ai1.2/1-36 ghz SHARING\] (WRC-07)

Sharing criteria in the band 36-37 GHz

1 The words used in this Annex are defined as follows:

*Point-to-point communication* is defined as communication provided by a
link, for example, a radio-relay link between two stations located at
specified fixed points.

*Point-to-multipoint communication* is defined as communication provided
by links, for example, radio-relay links between a single station
located at a specified fixed point (also called hub station in this
Annex) and a number of stations located at specified fixed points (also
called customer stations in this Annex).

*Automatic transmit-power control* (ATPC) is a technique in which the
output power of a microwave transmitter is automatically varied in
accordance with path conditions. In normal path conditions, the ATPC
maintains the transmitter output power at a reduced level. The ATPC is
characterized by the ATPC range which is defined as the difference
between the maximum and minimum value of transmitter power.

2 The sharing criteria applied to the fixed service are given in Table
1-1.

3 The sharing criteria applied to the mobile service are given in Table
1-2.

Sharing criteria applied to the fixed service

+-----------------------------------------------------+----------------+
| Parameter                                           | Value          |
+-----------------------------------------------------+----------------+
| Maximum elevation angle                             | 20°            |
+-----------------------------------------------------+----------------+
| ***Point-to-point systems***                        | --10 dBW ^1^   |
|                                                     |                |

| -- Maximum transmitter power of customer stations   |                |
+-----------------------------------------------------+----------------+
| ^1^ In the case of the fixed station point-to-point |                |
| systems using ATPC, the maximum transmitter power   |                |
| may be increased by a value corresponding to the    |                |
| ATPC range up to a maximum of --7 dBW.              |                |

| ^1^ Fixed use under the mobile service is wireless  |                |
| application in which the location of the end-user   |                |
| termination and the network access point to be      |                |
| connected to the end-user are not fixed but are     |                |
| seldom changed. The activity factor is taken to be  |                |
| 100%.                                               |                |

| ^2^ Nomadic use is defined as a wireless            |                |
| application in which the location of the end-user   |                |
| termination may be in different places but it must  |                |
| be stationary while in use. The activity factor is  |                |
| taken to be usually much less than the threshold    |                |
| value of 40%.                                       |                |

**Reasons:** The studies performed under Agenda item 1.2 and Resolution
742 (WRC-03) have shown that these sharing criteria would allow EESS
(passive) sensors to operate successfully in the band 36-37 GHz without
imposing undue constraints on the fixed and mobile services. See
ASP/41A2/14.

**SUP** ASP/41A2/16

RESOLUTION 742 (WRC-03)

Use of the frequency band 36-37 GHz

**Reasons:** The study has been completed in ITU-R under this Resolution
and therefore it can be deleted.
