Foreword
This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Broadband Radio Access
Networks (BRAN).
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.7] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.1].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.

Executive summary
The present document addresses the Broadband Direct Air-to-Ground Communications system based on the ETSI
System Reference Document ETSI TR 103 108 [i.6]. This System Requirement document was used by the ECC, in
conjunction with other contributions, to develop technology neutral ECC Decisions on the allocation of European
spectrum in the frequency bands 1 900 MHz to 1 920 MHz and 5 855 MHz to 5 875 MHz.
The technical requirements in the present document reflect, in part, the results of studies undertaken within the CEPT
on compatibility between broadband direct air-to-ground systems and other applications operating within, or adjacent
to, the frequency bands that are designated for Broadband DA2GC operations.

Foreword
This final draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee Broadband
Radio Access Networks (BRAN), and is now submitted for the Vote phase of the ETSI standards EN Approval
Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.7] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.1].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.
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
