Introduction
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.2] (for the 1 900 MHz to 1 920 MHz band) and ECC Report 210 [i.3] (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 bands and the 5 855 MHz to 5 875 MHz bands are contained within ECC Decision(15)02 [i.4] and ECC
Decision(15)03 [i.5] respectively.

4 Technical requirements specifications
4.1 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.
4.2 Conformance requirements
4.2.1 Introduction
This clause describes the conformance requirements for the DA2GC equipment. The requirements for the bands
1 900 MHz to 1 920 MHz and 5 855 MHz to 5 875 MHz are identical unless otherwise stated. Consequently, the
maximum channel bandwidth is 20 MHz for each band.
To meet the essential requirement of Directive 2014/53/EU [i.1] for DA2GC equipment five essential parameters have
been identified. Table 2 provides a cross reference between these five essential parameters and the corresponding ten
technical requirements for equipment within the scope of the present document.
To fulfill an essential parameter the compliance with all the corresponding technical requirements in table 2 shall be
verified.
The required performance REQPERF is defined as follows:
• For WCDMA modulation: "BER ≤ 0,1 %".
• For OFDMA modulation: "95 % of theoretical maximum throughput when using the QPSK modulation
scheme".
The reference sensitivity REFSENS is the minimum signal power required to achieve REQPERF.

4.1 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.
4.2 Conformance requirements
4.2.1 Introduction
This clause describes the conformance requirements for the DA2GC equipment. The requirements for the bands
1 900 MHz to 1 920 MHz and 5 855 MHz to 5 875 MHz are identical unless otherwise stated. Consequently, the
maximum channel bandwidth is 20 MHz for each band.
To meet the essential requirement of Directive 2014/53/EU [i.1] for DA2GC equipment five essential parameters have
been identified. Table 2 provides a cross reference between these five essential parameters and the corresponding ten
technical requirements for equipment within the scope of the present document.
To fulfill an essential parameter the compliance with all the corresponding technical requirements in table 2 shall be
verified.
The required performance REQPERF is defined as follows:
• For WCDMA modulation: "BER ≤ 0,1 %".
• For OFDMA modulation: "95 % of theoretical maximum throughput when using the QPSK modulation
scheme".
The reference sensitivity REFSENS is the minimum signal power required to achieve REQPERF.

ETSI ETSI EN 303 339 V1.1.1 (2016-06) 7 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. Introduction 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.2] (for the 1 900 MHz to 1 920 MHz band) and ECC Report 210 [i.3] (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 bands and the 5 855 MHz to 5 875 MHz bands are contained within ECC Decision(15)02 [i.4] and ECC Decision(15)03 [i.5] respectively.

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. 4.2 Conformance requirements 4.2.1 Introduction This clause describes the conformance requirements for the DA2GC equipment. The requirements for the bands 1 900 MHz to 1 920 MHz and 5 855 MHz to 5 875 MHz are identical unless otherwise stated. Consequently, the maximum channel bandwidth is 20 MHz for each band. To meet the essential requirement of Directive 2014/53/EU [i.1] for DA2GC equipment five essential parameters have been identified. Table 2 provides a cross reference between these five essential parameters and the corresponding ten technical requirements for equipment within the scope of the present document. To fulfill an essential parameter the compliance with all the corresponding technical requirements in table 2 shall be verified. The required performance REQPERF is defined as follows: • For WCDMA modulation: "BER ≤ 0,1 %". • For OFDMA modulation:
"95 % of theoretical maximum throughput when using the QPSK modulation scheme". The reference sensitivity REFSENS is the minimum signal power required to achieve REQPERF. SIST EN 303 339 V1.1.1:2016
