Sub-Part 20A -- Protection of EESS (passive) from unwanted emissions
within the\
band 1 400-1 427 MHz 3

Sub-Part 20B -- Protection of EESS (passive) from unwanted emissions
within the\
bands 23.6-24 GHz, 31.3-31.5 GHz, 50.2-50.4 GHz and 52.6-54.25 GHz 7

### Introduction {#introduction .heading_b1}

ITU-R Task Group 1/7 conducted studies between the EESS (passive) and
active services in certain adjacent or nearby bands, the results are
contained in Recommendation ITU-R SM.1633. The results of this work were
considered by WRC-03 under Agenda item 1.8.2.

CEPT made proposals to WRC-03 for the inclusion in the Radio Regulations
of limits on the unwanted emissions of active services to protect the
EESS (passive) in the bands 31.3-31.5 GHz and 52.6-54.25 GHz, and for
continued studies on other specific bands with the results to be
considered at WRC-07.

Many administrations supported regulatory measures for the protection of
passive services, including EESS, at WRC-03; however, after difficult
discussions up to the last few days of the Conference there was no
agreement to take such action. The compromise solution was to continue
the studies according to Resolution 738 and re-visit the issue at
WRC-07.

Within WRC-07 Agenda item 1.20 covered by Resolution 738, a total of
five EESS (passive) bands need to be addressed, i.e.:

1 400-1 427 MHz

23.6-24.0 GHz

31.3-31.5 GHz

50.2-50.4 GHz

52.6-54.25 GHz

The ECP on Agenda item 1.20 builds upon the results of work within TG
1/9 and has been split into two parts.

Sub-Part 20A

Protection of EESS (passive) from unwanted emissions within\
the band 1 400-1 427 MHz

### Introduction {#introduction-1 .heading_b1}

This sub-part deals with the issues under Agenda item 1.20 addressing
the EESS (passive) band 1 400-1 427 MHz.

The results of the compatibility analyses are mentioned in Table 1. It
should be noted that in most cases equipment complying with relevant
widely accepted standard, when available, or category B spurious limits
of Recommendation ITU-R SM.329 would also comply with the limits of the
table below.

Issue (A) resolves 1 and 3 (Resolution 738)

*Resolves* 1 reads as follows: "to invite ITU‑R to continue or to
initiate studies on the compatibility analyses between EESS (passive)
and the corresponding active services as listed in the Table with a view
to updating Recommendation ITU-R SM.1633 or developing additional
Recommendations", whereas *resolves* 3 is on the consideration of
regulatory measures for WRC-07 based on the previous resolves.

The proposal is based on a single entry unwanted emission mandatory
power limit applicable to a reference bandwidth in the EESS (passive)
band for each corresponding active service taking into account the
results of the compatibility analyses: those operational limits are
proposed to be included into a footnote in Article 5 similar to No.
5.482. Those limits are derived from part or all of Table 1 depending on
the result of studies documented in the Report ITU-R SM.2092.

In most cases, these studies have included equipments whose compliance
with relevant widely accepted standard, when available, or category B
spurious limits of Recommendation ITU-R SM.329, when applicable ensure
the compliance with the limits in most cases. They have also included
mitigation assumptions when needed, therefore providing an equitable
burden sharing between active and passive services.

Issue (A) resolves 1 and 3 (Resolution 738)

*Resolves* 1 reads as follows: "to invite ITU‑R to continue or to
initiate studies on the compatibility analyses between EESS (passive)
and the corresponding active services as listed in the Table with a view
to updating Recommendation ITU-R SM.1633 or developing additional
Recommendations", whereas *resolves* 3 is on the consideration of
regulatory measures for WRC‑07 based on the previous resolves.

The proposal is based on a single entry unwanted emission mandatory
power limit applicable to a reference bandwidth in the EESS (passive)
band for each corresponding active service taking into account the
results of the compatibility analysis: those operational limits are
proposed to be included in the Radio Regulations through a resolution.
A footnote in Article 5 similar to No. 5.347A would direct towards this
resolution. It is to be noted that the regulatory conditions of

those operational limits (non-retroactivity and non-examination by BR)
would also be included in this Resolution. Those limits are derived from
part or all of Table 1 depending on the result of studies documented in
the Report ITU-R SM.2092.

These studies have included equipments whose compliance with relevant
widely accepted standard, when available, or category B spurious limits
of Recommendation ITU-R SM.329 ensure the compliance with the limits in
most cases. They have also included mitigation assumptions when needed,
therefore providing an equitable burden sharing between active and
passive services.

Issue (B) resolves 2 and 3 (Resolution 738)

*Resolves* 2 reads as follows: "to invite ITU‑R to further study the
impact of implementing the values provided in *considering* *f)*
and *g)* for unwanted emissions of fixed-service systems operating in
Regions 2 and 3, taking into account that the impact on fixed-service
systems in Region 1 has already been investigated", whereas *resolves* 3
is on the consideration of regulatory measures for WRC-07 based on the
previous *resolves*.

DRAFT RESOLUTION \[EUR/10A20/12\] (WRC‑07)

Compatibility analyses between the Earth exploration-satellite\
service (passive) and active services

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that primary allocations have been made to various space services
in the Earth-to-space direction such as the fixed-satellite service
(FSS), inter-satellite service (ISS) and/or to terrestrial services such
as the fixed service (FS) hereafter referred to as "active services", in
bands adjacent or nearby to bands allocated to the Earth
exploration-satellite service (EESS) (passive);

*b)* that unwanted emissions from active services may cause unacceptable
interference to the EESS (passive);

*c)* that for technical or operational reasons, the general limits in
Appendix **3** may be insufficient in protecting the EESS (passive) in
specific bands;

*d)* that, in many cases, the frequencies used by the EESS (passive)
sensors are chosen 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;

*e)* that it is necessary to ensure an equitable burden sharing for
achieving compatibility between active and passive services operating in
adjacent or nearby bands,

noting

*a)* that frequency bands covered by RR No. **5.340** which prohibits
all emissions need to be fully protected as they are unique natural
resources;

*b)* that Report ITU‑R SM.2092 provides a methodology for conducting the
compatibility studies between active and passive services operating in
adjacent and nearby bands and develops all relevant scenarios;

*c)* that Recommendation ITU-R RS.1029-2 provides the interference
criteria for satellite passive remote sensing,

resolves

1 that unwanted emissions from stations, brought into use after the
\[date of entry into force of the revised Radio Regulations (WRC-07)\],
in the bands and services listed in Table 1-1 below, shall not exceed
the corresponding limits in the table;

2 that the Bureau shall make no examination or finding with respect to
this Resolution under either Article **9** or **11**.
