7 Final draft ETSI EN 301 444 V2.2.1 (2021-02)
Introduction
Following the WRC-03 decision [i.4] 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 [i.5], a new set of emission requirements for
LMESs and MMESs that are capable of transmitting in the frequency band from 1 668,0 MHz to 1 675,0 MHz is
specified.
The two parts of the L-band frequency allocations are treated as two sub-bands which may be used separately or in any
combination. The standard L-band allocation is referenced in the present document as "sub-band 1" and the extended
L-band is referenced as "sub-band 2".
Table 2c is applicable for LMESs and MMESs that are capable of transmitting in any combination of either or both of
these sub-bands. Table 2c is recommended for all new LMESs and MMESs including LMES and MMES that can only
operate in sub-band 1.
The manufacturer may choose between tables 2b and 2c for new LMESs and MMES that are capable of transmitting in
only the sub-band 1. The manufacturer has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs and MMESs under the new
Radio Equipment Directive 2014/53/EU [i.6].
Figure 1: Void
The present document is intended to cover the provisions of Directive 2014/53/EU [i.6] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
Recital 10 of Directive 2014/53/EU [i.6] states that "in order to ensure that radio equipment uses the radio spectrum
effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case
of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates
radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the
transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be
limited to such a level that, according to the state of the art, harmful interference is avoided; and, in the case of a
receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful
interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient
use of shared or adjacent channels".
Recital 11 of Directive 2014/53/EU [i.6] states that "although receivers do not themselves cause harmful interference,
reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an
increased resilience of receivers against harmful interference and unwanted signals on the basis of the relevant
essential requirements of Union harmonisation legislation".
As a consequence, the present document includes both transmitting and receiving parameters aiming to maximize the
efficient use of radio spectrum.

Introduction
Following the WRC-03 decision [i.4] 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 [i.5], a new set of emission requirements for
LMESs and MMESs that are capable of transmitting in the frequency band from 1 668,0 MHz to 1 675,0 MHz is
specified.
The two parts of the L-band frequency allocations are treated as two sub-bands which may be used separately or in any
combination. The standard L-band allocation is referenced in the present document as "sub-band 1" and the extended
L-band is referenced as "sub-band 2".
Table 2c is applicable for LMESs and MMESs that are capable of transmitting in any combination of either or both of
these sub-bands. Table 2c is recommended for all new LMESs and MMESs including LMES and MMES that can only
operate in sub-band 1.
The manufacturer may choose between tables 2b and 2c for new LMESs and MMES that are capable of transmitting in
only the sub-band 1. The manufacturer has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs and MMESs under the new
Radio Equipment Directive 2014/53/EU [i.6].
Figure 1: Void
The present document is intended to cover the provisions of Directive 2014/53/EU [i.6] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
Recital 10 of Directive 2014/53/EU [i.6] states that "in order to ensure that radio equipment uses the radio spectrum
effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case
of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates
radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the
transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be
limited to such a level that, according to the state of the art, harmful interference is avoided; and, in the case of a
receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful
interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient
use of shared or adjacent channels".
Recital 11 of Directive 2014/53/EU [i.6] states that "although receivers do not themselves cause harmful interference,
reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an
increased resilience of receivers against harmful interference and unwanted signals on the basis of the relevant
essential requirements of Union harmonisation legislation".
As a consequence, the present document includes both transmitting and receiving parameters aiming to maximize the
efficient use of radio spectrum.

1 Scope
The present document applies to Land Mobile Earth Stations (LMESs) and Maritime Mobile Earth Stations (MMESs)
radio equipment with an EIRP of greater than or equal to 15 dBW and less than or equal to 33 dBW and which have the
following characteristics:
• the LMES could be either vehicle mounted or portable equipment;
• these MMESs are installable equipment on ships;
• these LMESs and MMESs are controlled and monitored by a Network Control Facility (NCF). The NCF is
outside the scope of the present document;
• the LMES and MMES operate through geostationary satellites as part of a network providing voice and/or data
communications;
• these LMESs and MMESs operate with user bit-rates greater than 9,6 kbits/s;
• the LMES and MMESs are 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 and Maritime Mobile Satellite Service frequency bands

have a level greater than the specified unwanted emissions limits. The nominated bandwidth is wide
enough to take account of the transmit carrier frequency stability. The nominated bandwidth is within the
transmit frequency band within which the LMES and MMES operates.
operating band: frequency range over which the receiving equipment is able to operate as intended
Portable Equipment (PE): equipment generally intended to be self-contained, free standing and portable
NOTE: A PE would normally consist of a single module, but may consist of several interconnected modules.
sub-band: contiguous portion of the operating band
NOTE: Two sub-bands are defined (see table 1a).
transition frequency: frequency which separates adjacent frequency ranges in a table of limits
unwanted emissions: emissions falling outside the nominated bandwidth

Introduction
Following the WRC-03 decision [i.4] 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 [i.5], a new set of emission requirements for
LMESs and MMESs that are capable of transmitting in the frequency band from 1 668,0 MHz to 1 675,0 MHz is
specified.
The two parts of the L-band frequency allocations are treated as two sub-bands which may be used separately or in any
combination. The standard L-band allocation is referenced in the present document as "sub-band 1" and the extended
L-band is referenced as "sub-band 2".
Table 2c is applicable for LMESs and MMESs that are capable of transmitting in any combination of either or both of
these sub-bands. Table 2c is recommended for all new LMESs and MMESs including LMES and MMES that can only
operate in sub-band 1.
The manufacturer may choose between tables 2b and 2c for new LMESs and MMES that are capable of transmitting in
only the sub-band 1. The manufacturer has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs and MMESs under the new
Radio Equipment Directive 2014/53/EU [i.6].
Figure 1: Void
The present document is intended to cover the provisions of Directive 2014/53/EU [i.6] (RE Directive) article 3.2 which
states that "….radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
Recital 10 of Directive 2014/53/EU [i.6] states that "in order to ensure that radio equipment uses the radio spectrum
effectively and supports the efficient use of radio spectrum, radio equipment should be constructed so that: in the case
of a transmitter, when the transmitter is properly installed, maintained and used for its intended purpose it generates
radio waves emissions that do not create harmful interference, while unwanted radio waves emissions generated by the
transmitter (e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be
limited to such a level that, according to the state of the art, harmful interference is avoided; and, in the case of a
receiver, it has a level of performance that allows it to operate as intended and protects it against the risk of harmful
interference, in particular from shared or adjacent channels, and, in so doing, supports improvements in the efficient
use of shared or adjacent channels".
Recital 11 of Directive 2014/53/EU [i.6] states that "although receivers do not themselves cause harmful interference,
reception capabilities are an increasingly important factor in ensuring the efficient use of radio spectrum by way of an
increased resilience of receivers against harmful interference and unwanted signals on the basis of the relevant
essential requirements of Union harmonisation legislation".
As a consequence, the present document includes both transmitting and receiving parameters aiming to maximize the
efficient use of radio spectrum.
