ETSI ETSI EN 301 426 V2.1.2 (2016-11) 6 Introduction The present document is part of a set of standards developed by ETSI and is designed to fit a modular structure to cover all radio equipment under the Directive 2014/5
29、3/EU i.8. The modular structure is shown in ETSI EG 201 399 i.4. Figure 1: Void These requirements are in three major categories: emission limits: to protect other radio services from harmful interference generated by the Mobile Earth Station (MES) in normal use; MES Control and Monitoring Functions
30、 (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 MES; Receiver performance specifications: to enable reception of a wanted signal in the presence of other high p
31、ower signals in the adjacent channel and/or adjacent band. The requirements have been selected to ensure an adequate level of compatibility with other radio services. The levels, however, do not cover extreme cases which may occur in any location but with a low probability of occurrence. The present
32、 document may not cover those cases where a potential source of interference which is producing individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the near vicinity. In such a case it may be necessary to use special protection applied t
33、o either the source of interference, or the interfered part or both. The present document does not contain any requirement, recommendation or information about the installation of the MESs. Following the WRC-03 decision i.6 to allocate to MSS the bands 1 518 MHz to 1 525 MHz (space to Earth) and 1 6
34、68 MHz to 1 675 MHz (Earth to space) and the conclusions of WRC-07 i.7, 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 is specified. The two parts of the L-band frequency allocations are treated as two sub-bands whi
35、ch 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 that are capable of transmitting in any combination of either or both of these
36、 sub-bands. Table 2c is recommended for all new LMESs including LMES that can only operate in sub-band 1. The applicant may choose between tables 2b and 2c for new LMESs that are capable of transmitting in only the sub-band 1. The applicant has to declare which alternative is used. The present docum
37、ent specifies a new set of receiver performance requirements for LMESs under the new Radio Equipment Directive 2014/53/EU i.8. The present document was based on ETSI TBR 026 i.2. The present document is also based on ETSI ETS 300 740 i.3 (see annex B) for Maritime Mobile Earth Stations (MMES) not in
38、tended for distress and safety communications. The determination of the parameters of the user earth stations using a given geo-stationary 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
39、network operators. For MESs operating in satellite networks using satellites which also provide radio navigation service and/or other safety services should note that such satellite network operators or satellite operators may require testing in addition to the present document to prove correct inte
40、rworking in order to avoid the MES causing harmful interference which endangers the functioning of these services. References to these requirements will be listed in annex A of the present document as they become known. ETSI ETSI EN 301 426 V2.1.2 (2016-11) 7 The present document is therefore intend
41、ed to cover the provisions of Directive 2014/53/EU i.8 (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.8
42、 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 pu
43、rpose 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
44、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
45、 in the efficient use of shared or adjacent channels“. Recital 11 of Directive 2014/53/EU i.8 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 increas
46、ed 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 rad
47、io spectrum. ETSI ETSI EN 301 426 V2.1.2 (2016-11) 8 1 Scope The present document applies to the following Mobile Earth Stations (MESs) radio equipment: Land Mobile Earth Stations (LMESs) radio equipment; and Maritime Mobile Earth Stations (MMESs) radio equipment not providing those distress and saf
