Foreword
This Harmonized European Standard (EN) has been produced by ETSI Technical Committee Satellite Earth Stations
and Systems (SES), and is now submitted for the Public Enquiry phase of the ETSI standards Two-step Approval
Procedure.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [7] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").
The requirements relevant to Directive 1999/5/EC [1] are summarised in annex A.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa
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 and telecommunications terminal equipment within the scope of the R&TTE Directive. The modular
structure is shown in 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.
The present document specifies new emission requirements for MESs 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 MESs.
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".
ETSI
7 Draft ETSI EN 301 681 V1.4.0 (2011-02)
A new table (table 3a) is added to the present document for MESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new 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 technical requirements in the present document are applied under article 3.2 of the R&TTE Directive [1],
concerning the effective uses of the spectrum allocated to terrestrial/space radio communication and orbital resources so
as to avoid harmful interference. These requirements are in two major categories:
• emissions limits: to protect other radio services from harmful interference generated by the MES in normal
use;
• MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted
transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network
Control Facilities (NCF) for its S-PCN.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in EN 301 682 [i.2].
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.

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.
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 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 1: A list of such ENs is included on the web site http://www.newapproach.org.
NOTE 2: These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document.

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.

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 a TDMA system).

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 and telecommunications terminal equipment within the scope of the R&TTE Directive [1]. The modular
structure is shown in 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.
The present document specifies new emission requirements for MESs 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 MESs.
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".
ETSI
7 Final draft ETSI EN 301 681 V1.4.0 (2011-09)
A new table (table 3a) is added to the present document for MESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new 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 technical requirements in the present document are applied under article 3.2 of the R&TTE Directive [1],
concerning the effective uses of the spectrum allocated to terrestrial/space radio communication and orbital resources so
as to avoid harmful interference. These requirements are in two major categories:
• emissions limits: to protect other radio services from harmful interference generated by the MES in normal
use;
• MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted
transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network
Control Facilities (NCF) for its S-PCN.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in EN 301 682 [i.2].
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.

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.
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 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 1: A list of such ENs is included on the web site http://www.newapproach.org.
NOTE 2: These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document.

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, or 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

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 and telecommunications terminal equipment within the scope of the R&TTE Directive [1]. The modular
structure is shown in 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.
The present document specifies new emission requirements for MESs 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 MESs.
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".
ETSI
7 ETSI EN 301 681 V1.4.1 (2011-11)
A new table (table 3a) is added to the present document for MESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new 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 technical requirements in the present document are applied under article 3.2 of the R&TTE Directive [1],
concerning the effective uses of the spectrum allocated to terrestrial/space radio communication and orbital resources so
as to avoid harmful interference. These requirements are in two major categories:
• emissions limits: to protect other radio services from harmful interference generated by the MES in normal
use;
• MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted
transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network
Control Facilities (NCF) for its S-PCN.
NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in EN 301 682 [i.2].
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.

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.
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 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 1: A list of such ENs is included on the web site http://www.newapproach.org.
NOTE 2: These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document.

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 and telecommunications terminal equipment within the scope of the R&TTE Directive [1]. The modular structure is shown in 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. The present document specifies new emission requirements for MESs 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 MESs.
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". SIST EN 301 681 V1.4.1:2012
ETSI ETSI EN 301 681 V1.4.1 (2011-11) 7 A new table (table 3a) is added to the present document for MESs that are capable of transmitting in any combination of either or both of these sub-bands. The new 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 technical requirements in the present document are applied under article 3.2 of the R&TTE Directive [1], concerning the effective uses of the spectrum allocated to terrestrial/space radio communication and orbital resources so as to avoid harmful interference. These requirements are in two major categories: • emissions limits: to protect other radio services from harmful interference generated by the MES in normal use; • MES Control and Monitoring Functions (CMF): to protect other radio services from unwanted transmissions from the MES. The CMF in each MES is capable of answering to commands from the Network Control Facilities (NCF) for its S-PCN. NOTE: The requirements for Network Control Facilities (NCF) for S-PCN are contained in EN 301 682 [i.2]. 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 ETSI EN 301 681 V1.4.1 (2011-11) 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. 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 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 1: A list of such ENs is included on the web site http://www.newapproach.org. NOTE 2: These MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.

NOTE 1: In the band 3 253,0 MHz to 3 321,0 MHz the maximum EIRP in one, and only one, 3 MHz measurement bandwidth shall not exceed -38 dBW. Elsewhere in this band the power limit in table 3 shall be applied.
In each of the bands 4 879,5 MHz to 4 981,5 MHz, 6 506,0 MHz to 6 642,0 MHz and 8 132,5 MHz to 8 302,5 MHz the maximum EIRP in one, and only one, 3 MHz measurement bandwidth shall not 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 a TDMA system).
