IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no

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.9] 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.5].
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.
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 which are designated for BDA2GC operations. These studies are described in ECC
Report 209 [i.1] (for the 1 900 MHz to 1 920 MHz band) and ECC Report 210 [i.2] (for the 5 855 MHz to 5 875 MHz
band).
The resulting technical and operational requirements to be applied to BDA2GC systems in the 1 900 MHz to
1 920 MHz band and the 5 855 MHz to 5 875 MHz band are contained within ECC Decision(15)02 [i.3] and ECC
Decision(15)03 [i.4] respectively.

National transposition dates
Date of adoption of this EN: 3 July 2017
Date of latest announcement of this EN (doa): 31 October 2017
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 April 2018
Date of withdrawal of any conflicting National Standard (dow): 30 April 2019

"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Executive summary
The present document addresses the Broadband Direct Air to Ground Communications system based on the System
Reference Document ETSI TR 101 599 [i.10]. ETSI TR 101 599 [i.10] 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 BDA2GC operations.
Introduction
The present document has been developed in accordance with the guidelines contained in ETSI EG 203 336 [i.6].

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.10] 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.5].
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.
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 which are designated for BDA2GC operations. These studies are described in ECC
Report 209 [i.1] (for the 1 900 MHz to 1 920 MHz band) and ECC Report 210 [i.2] (for the 5 855 MHz to 5 875 MHz
band).
The resulting technical and operational requirements to be applied to BDA2GC systems in the 1 900 MHz to
1 920 MHz band and the 5 855 MHz to 5 875 MHz band are contained within ECC Decision(15)02 [i.3] and ECC
Decision(15)03 [i.4] respectively.

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
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa

Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.

Executive summary
The present document addresses the Broadband Direct Air to Ground Communications system based on the System
Reference Document ETSI TR 101 599 [i.10]. ETSI TR 101 599 [i.10] 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 BDA2GC operations.
Introduction
The present document has been developed in accordance with the guidelines contained in ETSI EG 203 336 [i.6].

4 Technical requirements specifications
4.1 General
4.1.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document at all times when operating within the boundary limits of the declared operational
environmental profile.
4.1.2 General System Characteristics
The main characteristics of a beamforming BDA2GC system to which the present document applies are as follows:
• The system allows for a broadband connection to be established between an aircraft equipped with a BDA2GC
Aircraft Station (AS) and a Ground Station (GS). The system operates in TDD mode, using OFDM type
modulation with variable modulation and coding to optimize the link performance.
• The system uses automatic transmit power control in both directions (GS to AS and AS to GS) in order to
maintain the required signal level at the receiver input.
• Both the AS and the GS employ phased array antennas which produce dynamically shaped and steerable
beams such that the Ground Station and the Aircraft Station mutually track each other.
• A given GS can comprise up to four separate integrated radio transceivers/phased array antenna assemblies,
enabling each GS to cover the entire visible air space, at all azimuths, from horizon to horizon. However, for
reasons of spectrum compatibility with other services, a minimum operational elevation angle needs to be
maintained as specified in clause 4.2.5.2.
• Each of the GS integrated antenna arrays is capable of simultaneously producing multiple co-frequency shaped
beams so that a number of aircraft can be served from a given GS.
