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 left hand edge of the figure shows the different clauses of Article 3 of the Directive.
For article 3.3 various horizontal boxes are shown. Their dotted lines indicate that no essential requirements in these
areas have yet been adopted by the Commission. If such essential requirements are adopted, they will be elaborated in
individual standards whose scope is likely to be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum. The scopes of these standards
are specified either by frequency (normally in the case where frequency bands are harmonized) or by radio equipment
type.
For article 3.1(b), the diagram shows the new single multi-part product EMC standard for radio, and the existing
collection of generic and base standards currently used under the EMC Directive. The parts of this new standard will
become available in the second half of 2000, and the existing separate EMC standards will be used until it is available.
For article 3.1(a) the diagram shows the existing safety standards currently used under the LVD Directive and the
possibility of a new standard on health relating to radio emissions
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both.
The modular approach has been taken because:
- it minimizes the number of standards needed. Because equipment may have multiple interfaces and functions it
is not practicable to produce a single standard for each possible combination of functions that may occur in an
equipment;
- it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions;
without requiring alteration of standards that are already published.
The present document is based on EN 300 721 [6].
The requirements of the present document have been selected to ensure an adequate level of compatibility with other
radio services.
The present document does not contain any requirement, recommendation, or information about the installation of the
MESs.
The determination of the parameters of the user earth stations using a given satellite constellation for the protection of
the spectrum allocated to that satellite constellation, is considered to be under the responsibility of the satellite operator
or the satellite network operators.

1 Scope
The present document applies to Mobile Earth Stations (MES) providing Low Bit Rate Data Communications
(LBRDC) using Low Earth Orbiting (LEO) satellites and which have the following characteristics:
- the MES could be a Based MES (BMES), a Vehicle mounted MES (VMES), or a Portable MES (PMES);
- the MESs operate through satellites in Low Earth Orbit (LEO) as part of a network providing Low Bit Rate Data
Communications (LBRDC);
- these radio equipment types are capable of operating in all or any part of the frequency bands given in table 1.
Table 1: Frequency Ranges
MES Transmit frequencies and Service allocations MES Receive frequencies and Service allocations
(MHz) (MHz)
148 to 149,9 MSS 137 to 137,025 MSS
149,9 to 150,05 LMSS 137,025 to 137,175 MSS
235 to 322 MSS 137,175 to 137,825 MSS
335,4 to 399,9 MSS 137,825 to 138 MSS
399,9 to 400,05 LMSS 235 to 322 MSS
335,4 to 399,9 MSS
400,15 to 401 MSS
The present document is intended to cover the provisions of Article 3.2 of Directive 1999/5/EC [1] (R&TTE Directive),
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 ETSI web site.
NOTE 2: The MESs are controlled and monitored by a Network Control Facility (NCF). The NCF is outside the
scope of the present document.
