Foreword This Harmonized European Standard (EN) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Directive 98/34/EC [7] as amended by Directive 98/48/EC [8]. The title and reference to the present document are intended to be included in the publication in the Official Journal of the European Union of titles and references of Harmonized Standard under the Directive 1999/5/EC [1].

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.
