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 ETS
37、I 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 dec
38、ision 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
39、. 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
40、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
41、 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 t
42、hat 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 emi
43、ssions 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 inte
44、rference 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
45、 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
46、 harmful interference and unwanted signals on the basis of the relevant essential requirements of Union harmonisation legislation.“ 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
47、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
48、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 M
49、SS 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
