Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment within the scope of the RE Directive [9]. The modular structure is shown in ETSI
EG 201 399 [i.1]. The determination of the parameters of the user earth stations using a given 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.
ETSI
7 Draft ETSI EN 301 681 V2.1.0 (2016-02)
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,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 were 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 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".
Table 3a is applicable for MESs that are capable of transmitting in any combination of either or both of these sub-bands.
Table 3a is recommended for all new MESs, including MESs that can only operate in sub-band 1.
The applicant may choose between table 3 and table 3a for new MESs that are capable of transmitting in only the
sub-band 1: the applicant has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs under the new Radio
Equipment Directive 2014/53/EU [9].

1 Scope
The present document applies to S-PCN MES for Geostationary mobile satellite systems with an EIRP less than or
equal to 15 dBW.
The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth
Stations (MES) with both transmit and receive capabilities for operation in a Satellite Personal Communication
Network (S-PCN) in any combination of all or any part of the Mobile Satellite Service (MSS) frequency bands
sub-band 1 and sub-band 2 defined in table 1.
These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the
present document.
Table 1: Mobile Satellite Service (MSS) frequency band
Sub-band Transmission path MSS frequency band
1 MESs transmit 1 1 626,5 MHz to 1 660,5 MHz
MESs receive 1 1 525 MHz to 1 559 MHz
2 MESs transmit 2 1 668,0 MHz to 1 675,0 MHz
MESs receive 2 1 518,0 MHz to 1 525,0 MHz
An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may
be an element in a multimode terminal; it may consist of a number of modules with associated connections and user
interface, or may be a self contained single unit.
If the MES is an element in a multimode terminal, unless otherwise stated in the present document, its requirements
apply only to the S-PCN MES element of the terminal operating in the MSS frequency band given in table 1.
The present document is intended to cover the provisions of Directive 2014/53/EU [9] (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". 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 Radio Equipment Directive
(RED) [9] 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 Conformance requirements
4.2.1 Unwanted emissions outside the band 1 626,5 MHz to 1 660,5 MHz
and outside the band 1 668,0 MHz to 1 675,0 MHz (carrier-on state)
4.2.1.1 Justification
The technical requirements presented in this clause shall apply to all MESs that are capable of transmitting either in
sub-band 1, sub-band 2, or in both sub-bands as defined in table 1 for the purpose of:
• protection of other radio services operating outside the band 1 626,5 MHz to 1 660,5 MHz from emissions
caused by S-PCN MESs transmitting within the sub-band 1 frequency band as defined in table 1; and
• protection of other radio services operating outside the band 1 668,0 MHz to 1 675,0 MHz from emissions
caused by S-PCN MESs transmitting within the sub-band 2 frequency band as defined in table 1.
4.2.1.2 Technical requirements
Unwanted emissions from Mobile Earth Stations (LMESs) outside the band 1 626,5 MHz to 1 660,5 MHz and outside
the band 1 668 MHz to 1 675 MHz shall be below the following limits.
Unless otherwise stated the specification in this clause shall apply to all types of MESs notwithstanding their
transmitting capabilities within the frequency bands as defined in table 1:
1) For MES that are capable of transmitting within only the sub-band 1 frequency band as defined in table 1, the
maximum EIRP spectral density of the unwanted emissions from the MES outside the band 1 626,5 MHz to
1 660,5 MHz shall not exceed the limits in either table 3 or table 3a. The applicant shall declare which
alternative shall be used.
2) For MES that are capable of transmitting within only sub-band 2 frequency band or within both the sub-band 1
and sub-band 2 frequency bands, the maximum EIRP spectral density of the unwanted emissions from the
MES outside the bands 1 626,5 MHz to 1 660,5 MHz and 1 668,0 MHz to 1 675,0 MHz shall not exceed the
limits in table 3a.
In tables 3 and 3a, whenever a change of limit between adjacent frequency bands occurs, the lower of the two limits
shall apply at the transition frequency.

exceed -48 dBW. Elsewhere in this band the power limit in table 3 shall be applied.
NOTE 2: The average measurement method defined in clause 5.2.2.3 shall apply except that an averaging
period of 20 ms shall be used in the sub-band 1 573,42 MHz to 1 580,42 MHz.
NOTE 3: Measurement bandwidths less than 1 MHz are allowable provided the power in the narrower
bandwidth is integrated over 1 MHz.
NOTE 4: Linearly interpolated in dBW vs. Frequency.
NOTE 5: The power limits specified in the band 1 624,5 MHz to 1 626,5 MHz require further study. This study is
important to determine whether less stringent limits may enhance spectrum efficiency and utilization
immediately above 1 626,5 MHz.
NOTE 6: Peak Hold and Average measurements shall be performed as specified in clauses 5.2.2.2 and 5.2.2.3.
NOTE 7: For systems employing CDMA, the EIRP limits shall be decreased by 10 log (N) dB, where N is the
maximum number of MESs in the receive beam of the satellite to which these MESs are
communicating and which are expected to transmit simultaneously in the same frequency band within
that same beam. This number shall be declared by the manufacturer (N = 1 in

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment within the scope of the RE Directive [9]. The modular structure is shown in ETSI
EG 201 399 [i.1]. The determination of the parameters of the user earth stations using a given 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.
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, 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 were 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 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".
Table 3a is applicable for MESs that are capable of transmitting in any combination of either or both of these sub-bands.
Table 3a is recommended for all new MESs, including MESs that can only operate in sub-band 1.
The applicant may choose between table 3 and table 3a for new MESs that are capable of transmitting in only the
sub-band 1: the applicant has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs under the new Radio
Equipment Directive 2014/53/EU [9].

1 Scope
The present document applies to S-PCN MES for Geostationary mobile satellite systems with an EIRP less than or
equal to 15 dBW.
The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth
Stations (MES) with both transmit and receive capabilities for operation in a Satellite Personal Communication
Network (S-PCN) in any combination of all or any part of the Mobile Satellite Service (MSS) frequency bands
sub-band 1 and sub-band 2 defined in table 1.
These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the
present document.
Table 1: Mobile Satellite Service (MSS) frequency band
Sub-band Transmission path MSS frequency band
1 MESs transmit 1 1 626,5 MHz to 1 660,5 MHz
MESs receive 1 1 525 MHz to 1 559 MHz
2 MESs transmit 2 1 668,0 MHz to 1 675,0 MHz
MESs receive 2 1 518,0 MHz to 1 525,0 MHz
An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may
be an element in a multimode terminal; it may consist of a number of modules with associated connections and user
interface, or may be a self-contained single unit.
If the MES is an element in a multimode terminal, unless otherwise stated in the present document, its requirements
apply only to the S-PCN MES element of the terminal operating in the MSS frequency band given in table 1.
The present document is intended to cover the provisions of Directive 2014/53/EU [9] (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". 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 Radio Equipment Directive
(RED) [9] 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.

immediately above 1 626,5 MHz.
NOTE 6: Peak Hold and Average measurements shall be performed as specified in clauses 5.2.2.2 and 5.2.2.3.
NOTE 7: For systems employing CDMA, the EIRP limits shall be decreased by 10 log (N) dB, where N is the

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio equipment within the scope of the RE Directive [i.5]. The modular structure is shown in ETSI
EG 201 399 [i.1]. The determination of the parameters of the user earth stations using a given 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.
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, 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 were 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 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".
Table 3a is applicable for MESs that are capable of transmitting in any combination of either or both of these sub-bands.
Table 3a is recommended for all new MESs, including MESs that can only operate in sub-band 1.
The applicant may choose between table 3 and table 3a for new MESs that are capable of transmitting in only the
sub-band 1: the applicant has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs under the new Radio
Equipment Directive 2014/53/EU [i.5].
Figure 1: Void
Recital 10 of Directive 2014/53/EU [i.5] 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.5] 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."

1 Scope
The present document applies to S-PCN MES for Geostationary mobile satellite systems with an EIRP less than or
equal to 15 dBW.
The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth
Stations (MES) with both transmit and receive capabilities for operation in a Satellite Personal Communication
Network (S-PCN) in any combination of all or any part of the Mobile Satellite Service (MSS) frequency bands
sub-band 1 and sub-band 2 defined in table 1.
These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the
present document.
Table 1: Mobile Satellite Service (MSS) frequency band
Sub-band Transmission path MSS frequency band
1 MESs transmit 1 1 626,5 MHz to 1 660,5 MHz
MESs receive 1 1 525 MHz to 1 559 MHz
2 MESs transmit 2 1 668,0 MHz to 1 675,0 MHz
MESs receive 2 1 518,0 MHz to 1 525,0 MHz
An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may
be an element in a multimode terminal; it may consist of a number of modules with associated connections and user
interface, or may be a self-contained single unit.
If the MES is an element in a multimode terminal, unless otherwise stated in the present document, its requirements
apply only to the S-PCN MES element of the terminal operating in the MSS frequency band given in table 1.
The present document is intended to cover the provisions of Directive 2014/53/EU [i.5] (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". 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 Radio Equipment Directive
(RED) [i.5] 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.

ETSI ETSI EN 301 681 V2.1.2 (2016-11) 7 Introduction The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio equipment within the scope of the RE Directive [i.5]. The modular structure is shown in ETSI EG 201 399 [i.1]. The determination of the parameters of the user earth stations using a given 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. 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, 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 were 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 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". Table 3a is applicable for MESs that are capable of transmitting in any combination of either or both of these sub-bands. Table 3a is recommended for all new MESs, including MESs that can only operate in sub-band 1. The applicant may choose between table 3 and table 3a for new MESs that are capable of transmitting in only the sub-band 1: the applicant has to declare which alternative is used.
The present document specifies a new set of receiver performance requirements for LMESs under the new Radio Equipment Directive 2014/53/EU [i.5]. Figure 1: Void Recital 10 of Directive 2014/53/EU [i.5] 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.5] 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." SIST EN 301 681 V2.1.2:2017
ETSI ETSI EN 301 681 V2.1.2 (2016-11) 8 1 Scope The present document applies to S-PCN MES for Geostationary mobile satellite systems with an EIRP less than or equal to 15 dBW. The present document sets out the minimum performance requirements and technical characteristics of Mobile Earth Stations (MES) with both transmit and receive capabilities for operation in a Satellite Personal Communication Network (S-PCN) in any combination of all or any part of the Mobile Satellite Service (MSS) frequency bands sub-band 1 and sub-band 2 defined in table 1. These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document. Table 1: Mobile Satellite Service (MSS) frequency band Sub-band Transmission path MSS frequency band 1 MESs transmit 1 1 626,5 MHz to 1 660,5 MHz MESs receive 1 1 525 MHz to 1 559 MHz 2 MESs transmit 2 1 668,0 MHz to 1 675,0 MHz MESs receive 2 1 518,0 MHz to 1 525,0 MHz
An S-PCN MES may be handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may be an element in a multimode terminal; it may consist of a number of modules with associated connections and user interface, or may be a self-contained single unit. If the MES is an element in a multimode terminal, unless otherwise stated in the present document, its requirements apply only to the S-PCN MES element of the terminal operating in the MSS frequency band given in table 1. The present document is intended to cover the provisions of Directive 2014/53/EU [i.5] (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". 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 Radio Equipment Directive (RED) [i.5] may apply to equipment within the scope of the present document.
