Introduction
The requirements defined in the present document have been selected to ensure an adequate level of compatibility with
other radio services. The levels, however, do not cover extreme cases, which may occur in any location but with a low
probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.
The present document does not contain any requirement, recommendation or information about the installation of the
LMES.
ETSI
6 Final draft ETSI EN 301 444 V1.2.0 (2011-11)
The previous version [6] of this harmonized standard contained two sets of limits to provide a transition from
TBR 044 [4]. One set of limits (table 2a) was applicable up to 1 June 2002 and a more stringent set (table 2b) was
applicable after this date. The first set of limits (table 2a) has been removed in the present document since it is no longer
required. The second set of limits (table 2b) is retained for existing and legacy LMES and may continue to be used for
LMES that only operate in the original L-band allocation (sub-band 1 as defined in table 1a).
The determination of the parameters of the user earth stations using a given geo-stationary satellite for the protection of
the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the
satellite network operators. Applicants for LMESs operating in satellite networks which provide radio navigation service
and/or other safety services should note that such satellite network operators may require testing in addition to the
present document to prove correct interworking in order to avoid the LMES causing harmful interference which
endangers the functioning of these services. References to these requirements will be listed in the Bibliography of the
present document as they become known.
The present document specifies a new set of emission requirements for LMESs that are capable of transmitting in the
frequency band from 1 668,0 MHz to 1 675,0 MHz. Following the WRC-03 decision to allocate to MSS the bands
1 518 MHz to 1 525 MHz (space to Earth) and 1 668 MHz to 1 675 MHz (Earth to space) and the conclusions of
WRC-07, the present document specifies the necessary requirements to harmonise the use of these extended frequency
bands by LMESs.
The present document treats the two parts of the L-band frequency allocation (as extended) as two sub-bands which
may be used separately or in any combination. The original L-band allocation is referenced in the present document as
"sub-band 1" and the extended L-band is referenced as "sub-band 2".
A new table 2c is added to the present document for LMESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new table 2c is recommended for all new LMESs including LMES that can only
operate in sub-band 1.
The applicant may choose between tables 2b and 2c for new LMESs that are capable of transmitting in only the
sub-band 1. The applicant has to declare which alternative is used.

1 Scope
The present document applies to Land Mobile Earth Stations (LMESs) radio equipment with an EIRP less than or equal
to 33 dBW and which have the following characteristics:
• the LMES could be either vehicle mounted or portable equipment;
• these LMESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document;
• the LMES operate through geostationary satellites as part of a network providing voice and/or data
communications;
• the LMES is capable of operating in any combination of all or any part of the frequency ranges sub-band 1 and
sub-band 2 defined in table 1a.
Table 1a: Land Mobile Satellite Service frequency bands
Sub-Band Direction of transmission LMSS frequency bands
1 Transmit 1 (Earth to space) 1 631,5 MHz to 1 660,5 MHz
Receive 1 (space to Earth) 1 525,0 MHz to 1 559,0 MHz
2 Transmit 2 (Earth to space) 1 668,0 MHz to 1 675,0 MHz
Receive 2 (space to Earth) 1 518,0 MHz to 1 525,0 MHz

The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

4.2.2 Maximum unwanted emissions within the 1 625,8 MHz
to1 661,2 MHz band and within the 1 667,3 MHz to 1 675,7 MHz
band
4.2.2.1 Justification
The technical requirements presented in this clause shall apply to all LMESs that are capable of transmitting either in
sub-band 1, or sub-band 2, or in both sub-bands as defined in table 1a for the purpose of:
• protection of satellite and terrestrial services operating in the 1 625,8 MHz to 1 661,2 MHz frequency band;
and
• protection of satellite and terrestrial services operating in the 1 667,3 MHz to 1 675,7 MHz frequency band.
4.2.2.2 Specifications
If an LMES is capable of transmitting in both sub-band 1 and sub-band 2 as defined in table 1a, there are two different
limits in this clause. The limits defined in table 3 shall only apply for the current transmit band as defined below.
ETSI
13 Final draft ETSI EN 301 444 V1.2.0 (2011-11)
Specification 1: Carrier-on state
For LMES transmitting in sub-band 1 (as defined in table 1a), the unwanted emission EIRP in any 3 kHz band within
the 1 625,8 MHz to 1 661,2 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and
the emission limits within the 1 667,3 MHz to 1 675,7 MHz frequency band shall not exceeded 74 dBpW in any
100 kHz measurement bandwidth.
NOTE 1: If an applicant declares to use table 2b for an LMES the same emission limit for the 1 667,3 MHz to
1 675,7 MHz frequency band is also defined in table 2b.
For LMES transmitting in sub-band 2 (as defined in table 1a), the unwanted emission EIRP in any 3 kHz band within
the 1 667,3 MHz to 1 675,7 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and
the emission limits within the 1 625,8 MHz to 1 661,2 MHz frequency band shall not exceeded 74 dBpW in any
100 kHz measurement bandwidth.
Table 3: Limits for unwanted emissions within the 1 625,8 MHz to 1 661,2 MHz band

Greater than 700 75
If an applicant declares to use table 2b for an LMES the limits in table 3 may be exceeded provided that the sum in
watts of the spectrum components exceeding the limits of table 3 does not exceed 104 dBpW. This additional
requirement is retained for compatibility with the previous version [6] of the present document.
Specification 2: Carrier-off state
For LMES which is capable of transmitting in either sub-band 2 only or in both sub-band 1 and sub-band 2 (as defined
in table 1a), Specification 2a shall apply. This requirement shall also apply if an applicant declares to use table 2c for
LMES capable of transmitting in sub-band 1 only and should also apply if an applicant declares to use table 2b.
Specification 2a: The EIRP of any emission in any 100 kHz band within the 1 625,8 MHz to 1 661,2 MHz
band and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 48 dBpW.
However, if an applicant declares to use table 2b for LMES capable of transmitting in sub-band 1 only (as defined in
table 1a), then Specification 2b shall apply:
Specification 2b: The EIRP of any emission in any 3 kHz band within the 1 625,8 MHz to 1 661,2 MHz band
and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 57 dBpW.
NOTE 2: Specification 2b is retained for compatibility with the previous version [6] of the present document.

Introduction
The requirements defined in the present document have been selected to ensure an adequate level of compatibility with
other radio services. The levels, however, do not cover extreme cases, which may occur in any location but with a low
probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.
The present document does not contain any requirement, recommendation or information about the installation of the
LMES.
ETSI
6 ETSI EN 301 444 V1.2.1 (2012-01)
The previous version [6] of this harmonized standard contained two sets of limits to provide a transition from
TBR 044 [4]. One set of limits (table 2a) was applicable up to 1 June 2002 and a more stringent set (table 2b) was
applicable after this date. The first set of limits (table 2a) has been removed in the present document since it is no longer
required. The second set of limits (table 2b) is retained for existing and legacy LMES and may continue to be used for
LMES that only operate in the original L-band allocation (sub-band 1 as defined in table 1a).
The determination of the parameters of the user earth stations using a given geo-stationary satellite for the protection of
the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the
satellite network operators. Applicants for LMESs operating in satellite networks which provide radio navigation service
and/or other safety services should note that such satellite network operators may require testing in addition to the
present document to prove correct interworking in order to avoid the LMES causing harmful interference which
endangers the functioning of these services. References to these requirements will be listed in the Bibliography of the
present document as they become known.
The present document specifies a new set of emission requirements for LMESs that are capable of transmitting in the
frequency band from 1 668,0 MHz to 1 675,0 MHz. Following the WRC-03 decision to allocate to MSS the bands
1 518 MHz to 1 525 MHz (space to Earth) and 1 668 MHz to 1 675 MHz (Earth to space) and the conclusions of
WRC-07, the present document specifies the necessary requirements to harmonise the use of these extended frequency
bands by LMESs.
The present document treats the two parts of the L-band frequency allocation (as extended) as two sub-bands which
may be used separately or in any combination. The original L-band allocation is referenced in the present document as
"sub-band 1" and the extended L-band is referenced as "sub-band 2".
A new table 2c is added to the present document for LMESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new table 2c is recommended for all new LMESs including LMES that can only
operate in sub-band 1.
The applicant may choose between tables 2b and 2c for new LMESs that are capable of transmitting in only the
sub-band 1. The applicant has to declare which alternative is used.

1 Scope
The present document applies to Land Mobile Earth Stations (LMESs) radio equipment with an EIRP less than or equal
to 33 dBW and which have the following characteristics:
• the LMES could be either vehicle mounted or portable equipment;
• these LMESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document;
• the LMES operate through geostationary satellites as part of a network providing voice and/or data
communications;
• the LMES is capable of operating in any combination of all or any part of the frequency ranges sub-band 1 and
sub-band 2 defined in table 1a.
Table 1a: Land Mobile Satellite Service frequency bands
Sub-Band Direction of transmission LMSS frequency bands
1 Transmit 1 (Earth to space) 1 631,5 MHz to 1 660,5 MHz
Receive 1 (space to Earth) 1 525,0 MHz to 1 559,0 MHz
2 Transmit 2 (Earth to space) 1 668,0 MHz to 1 675,0 MHz
Receive 2 (space to Earth) 1 518,0 MHz to 1 525,0 MHz

The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

band
4.2.2.1 Justification
The technical requirements presented in this clause shall apply to all LMESs that are capable of transmitting either in
sub-band 1, or sub-band 2, or in both sub-bands as defined in table 1a for the purpose of:
• protection of satellite and terrestrial services operating in the 1 625,8 MHz to 1 661,2 MHz frequency band;
and
• protection of satellite and terrestrial services operating in the 1 667,3 MHz to 1 675,7 MHz frequency band.
ETSI
13 ETSI EN 301 444 V1.2.1 (2012-01)
4.2.2.2 Specifications
If an LMES is capable of transmitting in both sub-band 1 and sub-band 2 as defined in table 1a, there are two different
limits in this clause. The limits defined in table 3 shall only apply for the current transmit band as defined below.
Specification 1: Carrier-on state
For LMES transmitting in sub-band 1 (as defined in table 1a), the unwanted emission EIRP in any 3 kHz band within
the 1 625,8 MHz to 1 661,2 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and
the emission limits within the 1 667,3 MHz to 1 675,7 MHz frequency band shall not exceeded 74 dBpW in any
100 kHz measurement bandwidth.
NOTE 1: If an applicant declares to use table 2b for an LMES the same emission limit for the 1 667,3 MHz to
1 675,7 MHz frequency band is also defined in table 2b.
For LMES transmitting in sub-band 2 (as defined in table 1a), the unwanted emission EIRP in any 3 kHz band within
the 1 667,3 MHz to 1 675,7 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and
the emission limits within the 1 625,8 MHz to 1 661,2 MHz frequency band shall not exceeded 74 dBpW in any
100 kHz measurement bandwidth.
Table 3: Limits for unwanted emissions within the 1 625,8 MHz to 1 661,2 MHz band
and within the 1 667,3 MHz to 1 675,7 MHz band

20 to 100 105
100 to 200 95
200 to 700 85
Greater than 700 75
If an applicant declares to use table 2b for an LMES the limits in table 3 may be exceeded provided that the sum in
watts of the spectrum components exceeding the limits of table 3 does not exceed 104 dBpW. This additional
requirement is retained for compatibility with the previous version [6] of the present document.
Specification 2: Carrier-off state
For LMES which is capable of transmitting in either sub-band 2 only or in both sub-band 1 and sub-band 2 (as defined
in table 1a), Specification 2a shall apply. This requirement shall also apply if an applicant declares to use table 2c for
LMES capable of transmitting in sub-band 1 only and should also apply if an applicant declares to use table 2b.
Specification 2a: The EIRP of any emission in any 100 kHz band within the 1 625,8 MHz to 1 661,2 MHz
band and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 48 dBpW.
However, if an applicant declares to use table 2b for LMES capable of transmitting in sub-band 1 only (as defined in
table 1a), then Specification 2b shall apply:
Specification 2b: The EIRP of any emission in any 3 kHz band within the 1 625,8 MHz to 1 661,2 MHz band
and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 57 dBpW.
NOTE 2: Specification 2b is retained for compatibility with the previous version [6] of the present document.
Specification 2a is recommended for all new LMES.
4.2.2.3 Conformance test
Conformance test shall be carried out in accordance with clause 5.2.2.
ETSI
14 ETSI EN 301 444 V1.2.1 (2012-01)
4.2.3 Control and Monitoring Functions (CMF)
4.2.3.1 General
The following minimum set of CMF shall be implemented in LMES in order to minimize the probability that they
originate unwanted transmissions that may give rise to harmful interference to other systems.
Under any fault condition when the LMES transmissions are being suppressed the limits for carrier-off state shall apply.
4.2.3.2 Processor monitoring
4.2.3.2.1 Justification
To ensure that the LMES can suppress transmissions in the event of a processor sub-system failure.
4.2.3.2.2 Specification
The LMES shall incorporate a processor monitoring function for each of its processors involved in the manipulation of
traffic and in Control and Monitoring Functions (CMF).
The processor monitoring function shall detect any failure of the processor hardware and software.
No later than one second after any fault condition occurs, the LMES shall enter the carrier-off state until the processor
monitoring function has determined that all fault conditions have been cleared.
4.2.3.2.3 Conformance test
Conformance test shall be carried out in accordance with clause 5.2.3.3.
4.2.3.3 Transmit subsystem monitoring
4.2.3.3.1 Justification
To ensure the correct operation of the transmit frequency generation sub-system and to inhibit transmissions should the
sub-system fail.
4.2.3.3.2 Specification
The LMES shall monitor the operation of its transmit frequency generation sub-system.
No later than 5 seconds after any fault condition of the transmit frequency generation sub-system occurs, the LMES
shall enter the carrier-off state until the transmit sub-system monitoring function has determined that all fault conditions
have been cleared.
4.2.3.3.3 Conformance test
Conformance test shall be carried out in accordance with clause 5.2.3.4.
4.2.3.4 Power-on/reset
4.2.3.4.1 Justification
To demonstrate that the LMES achieves a controlled non-transmitting state following the powering of the unit, or the
occurrence of a reset made by a local operator when this function is implemented.
4.2.3.4.2 Specification
During and following "power-on" or a manual reset when this function is implemented, the LMES shall remain in the
carrier-off state.

Introduction
The requirements defined in the present document have been selected to ensure an adequate level of compatibility with
other radio services. The levels, however, do not cover extreme cases, which may occur in any location but with a low
probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.
The present document does not contain any requirement, recommendation or information about the installation of the
LMES.
ETSI
6 ETSI EN 301 444 V1.2.1 (2012-01)
The previous version [6] of this harmonized standard contained two sets of limits to provide a transition from
TBR 044 [4]. One set of limits (table 2a) was applicable up to 1 June 2002 and a more stringent set (table 2b) was
applicable after this date. The first set of limits (table 2a) has been removed in the present document since it is no longer
required. The second set of limits (table 2b) is retained for existing and legacy LMES and may continue to be used for
LMES that only operate in the original L-band allocation (sub-band 1 as defined in table 1a).
The determination of the parameters of the user earth stations using a given geo-stationary satellite for the protection of
the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the
satellite network operators. Applicants for LMESs operating in satellite networks which provide radio navigation service
and/or other safety services should note that such satellite network operators may require testing in addition to the
present document to prove correct interworking in order to avoid the LMES causing harmful interference which
endangers the functioning of these services. References to these requirements will be listed in the Bibliography of the
present document as they become known.
The present document specifies a new set of emission requirements for LMESs that are capable of transmitting in the
frequency band from 1 668,0 MHz to 1 675,0 MHz. Following the WRC-03 decision to allocate to MSS the bands
1 518 MHz to 1 525 MHz (space to Earth) and 1 668 MHz to 1 675 MHz (Earth to space) and the conclusions of
WRC-07, the present document specifies the necessary requirements to harmonise the use of these extended frequency
bands by LMESs.
The present document treats the two parts of the L-band frequency allocation (as extended) as two sub-bands which
may be used separately or in any combination. The original L-band allocation is referenced in the present document as
"sub-band 1" and the extended L-band is referenced as "sub-band 2".
A new table 2c is added to the present document for LMESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new table 2c is recommended for all new LMESs including LMES that can only
operate in sub-band 1.
The applicant may choose between tables 2b and 2c for new LMESs that are capable of transmitting in only the
sub-band 1. The applicant has to declare which alternative is used.

1 Scope
The present document applies to Land Mobile Earth Stations (LMESs) radio equipment with an EIRP less than or equal
to 33 dBW and which have the following characteristics:
• the LMES could be either vehicle mounted or portable equipment;
• these LMESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document;
• the LMES operate through geostationary satellites as part of a network providing voice and/or data
communications;
• the LMES is capable of operating in any combination of all or any part of the frequency ranges sub-band 1 and
sub-band 2 defined in table 1a.
Table 1a: Land Mobile Satellite Service frequency bands
Sub-Band Direction of transmission LMSS frequency bands
1 Transmit 1 (Earth to space) 1 631,5 MHz to 1 660,5 MHz
Receive 1 (space to Earth) 1 525,0 MHz to 1 559,0 MHz
2 Transmit 2 (Earth to space) 1 668,0 MHz to 1 675,0 MHz
Receive 2 (space to Earth) 1 518,0 MHz to 1 525,0 MHz

The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site http://www.newapproach.org.

4.2.2.2 Specifications
If an LMES is capable of transmitting in both sub-band 1 and sub-band 2 as defined in table 1a, there are two different
limits in this clause. The limits defined in table 3 shall only apply for the current transmit band as defined below.
Specification 1: Carrier-on state
For LMES transmitting in sub-band 1 (as defined in table 1a), the unwanted emission EIRP in any 3 kHz band within
the 1 625,8 MHz to 1 661,2 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and

If an applicant declares to use table 2b for an LMES the limits in table 3 may be exceeded provided that the sum in
watts of the spectrum components exceeding the limits of table 3 does not exceed 104 dBpW. This additional
requirement is retained for compatibility with the previous version [6] of the present document.
Specification 2: Carrier-off state
For LMES which is capable of transmitting in either sub-band 2 only or in both sub-band 1 and sub-band 2 (as defined
in table 1a), Specification 2a shall apply. This requirement shall also apply if an applicant declares to use table 2c for
LMES capable of transmitting in sub-band 1 only and should also apply if an applicant declares to use table 2b.
Specification 2a: The EIRP of any emission in any 100 kHz band within the 1 625,8 MHz to 1 661,2 MHz
band and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 48 dBpW.
However, if an applicant declares to use table 2b for LMES capable of transmitting in sub-band 1 only (as defined in
table 1a), then Specification 2b shall apply:
Specification 2b: The EIRP of any emission in any 3 kHz band within the 1 625,8 MHz to 1 661,2 MHz band
and the 1 667,3 MHz to 1 675,7 MHz band shall not exceed 57 dBpW.
NOTE 2: Specification 2b is retained for compatibility with the previous version [6] of the present document.
Specification 2a is recommended for all new LMES.
4.2.2.3 Conformance test
Conformance test shall be carried out in accordance with clause 5.2.2.
ETSI
14 ETSI EN 301 444 V1.2.1 (2012-01)
4.2.3 Control and Monitoring Functions (CMF)
4.2.3.1 General
The following minimum set of CMF shall be implemented in LMES in order to minimize the probability that they
originate unwanted transmissions that may give rise to harmful interference to other systems.
Under any fault condition when the LMES transmissions are being suppressed the limits for carrier-off state shall apply.
4.2.3.2 Processor monitoring
4.2.3.2.1 Justification
To ensure that the LMES can suppress transmissions in the event of a processor sub-system failure.
4.2.3.2.2 Specification
The LMES shall incorporate a processor monitoring function for each of its processors involved in the manipulation of
traffic and in Control and Monitoring Functions (CMF).
The processor monitoring function shall detect any failure of the processor hardware and software.
No later than one second after any fault condition occurs, the LMES shall enter the carrier-off state
