Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM), and is now submitted for the Public
Enquiry phase of the ETSI standards Two-step Approval Procedure.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [11] 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 present document provides the technical procedures and limits for compliance with the R&TTE directive. For use
in civil ground to air communications the full requirements of the latest version of EN 301 842 parts 1 to 5 and such
requirements as defined by the Single European Sky regulations are required to be met before the equipment can be
brought into operation.
The present document is part 6 of a multi-part deliverable covering the VHF air-ground Digital Link (VDL) Mode 4
radio equipment; Technical characteristics and methods of measurement for ground-based equipment, as identified
below:
Part 1: "EN for ground equipment";
Part 2: "General description and data link layer";
Part 3: "Additional broadcast aspects";
Part 4: "Point-to-point functions";
Part 5: "VDL 4 ground based equipment compliance with the SES 552/2004 interoperability Regulation";
Part 6: "Harmonized EN covering essential requirements of article 3.2 of the R&TTE Directive".
The present document is accompanied by an equivalent airborne standard, EN 302 842 [10] parts 1 to 5, covering the
VHF air-ground Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement
for airborne equipment.

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the R&TTE Directive [11]. The
modular structure is shown in EG 201 399 [13].
The present document states the essential requirements for Very High Frequency (VHF) Digital Link (VDL) Mode 4
ground-based radio transmitters, transceivers and receivers for air-ground communications operating in the VHF band,
using Gaussian-filtered Frequency Shift Keying (GFSK) Modulation with 25 kHz channel spacing and capable of
tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL)
Standards and Recommended Practices (SARPs) [2].
The present document may be used to produce tests for the assessment of the performance of the equipment. The
performance of the equipment submitted for type testing should be representative of the performance of the
corresponding production model.
The present document has been written on the assumption that:
• the type test measurements will be performed only once, in an accredited test laboratory, and the
measurements will be accepted by the various authorities in order to grant type approval;
• if equipment available on the market is required to be checked it may be tested in accordance with the
methods of measurement specified in the present document or a documented alternative approved by the
certifying authority;
• equipment comply with EN 301 489-22 [6].
The present document also indicates VDL Mode 4 compliance with the SES 552/2004 Regulation [12].

1 Scope
The present document applies to the following radio equipment types:
1) Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio transmitters and receivers for
air-ground communications operating in the VHF band, using Gaussian-filtered Frequency Shift Keying
(GFSK) Modulation with 25 kHz channel spacing and capable of tuning to any of the 25 kHz channels from
118,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL) Standards and Recommended
Practices (SARPs) [2].
The present document provides part 6 of the technical specifications.
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 117,975 MHz.
The scope of the present document is limited to ground stations. The equivalent specification for airborne stations is
EN 302 842 [10].
The VDL Mode 4 system provides digital communication exchanges between aircraft and ground-based systems and
other aircraft supporting surveillance and communication applications. The supported modes of communication include:
• broadcast and point-to-point communication;
• broadcast services including Automatic Dependent Surveillance - Broadcast (ADS-B), Traffic Information
Service - Broadcast (TIS-B) and Flight Information Service - Broadcast (FIS-B) capabilities;
• air-air, air-to-ground, and ground-to-air services;
• operation without ground infrastructure.
The present document is derived from the specifications:
• VDL Mode 4 standards produced under the auspices of the International Civil Aviation Organization
(ICAO) [1] and [2].
• Other relevant standards as defined in clause 2.
It is envisaged that manufacturers may provide equipment supporting:
• broadcast services only;
• point-to-point services only;
• both broadcast and point-to-point services.
The present document is intended to cover the provisions of Directive 1999/5/EC [11] (R&TTE Directive):
Article 3.2, 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".
The present document includes:
• clause 2 provides references to relevant documents;
• clause 3 provides general definitions, abbreviations and symbols used;
• clause 4 refers to a general description and architecture of VDL Mode 4 contained in
EN 301 842-2 [8];
• clause 5 provides technical requirements specifications applicable to Article 3.2;
• clause 6 provides a description of testing for compliance with the technical requirements;
• annex A provides the HS Requirement & conformance Test specifications Table (HS-RTT);

Mandating and Recommendation Phrases
a) "Shall"
The use of the word "Shall" indicates a mandated criterion; i.e. compliance with the particular procedure or
specification is mandatory and no alternative may be applied.
b) "Should"
The use of the word "Should" (and phrases such as "It is recommended that.", etc.) indicate that though the
procedure or criterion is regarded as the preferred option, alternative procedures, specifications or criteria may
be applied, provided that the manufacturer, installer or tester can provide information or data to adequately
support and justify the alternative.

3.1.3 General definitions
For the purposes of the present document, the terms and definitions given in the R&TTE Directive [11] and the
following apply:
adjacent channel power: amount of the modulated RF signal power which falls within a given adjacent channel
NOTE: Adjacent channel power includes discrete spurious, signal sidebands, and noise density (including phase
noise) at the transmitter output.
Automatic Dependent Surveillance-Broadcast (ADS-B): surveillance application transmitting parameters, such as
position, track and ground speed, via a broadcast mode data link for use by any air and ground users requiring it
NOTE: ADS-B is a surveillance service based on aircraft self-determination of position/velocity/time and
automatic, periodic or random, broadcast of this information along with auxiliary data such as aircraft
identity (ID), communications control parameters, etc. ADS-B is intended to support multiple high-level
applications and associated services such as cockpit display of traffic information, traffic alert and
collision avoidance functionality, enhanced traffic management in the air and on the ground, search and
rescue support and others.
Bit Error Rate (BER): expressed as the ratio between the number of erroneous bits received and the total number of
bits received
data rate: Mode 4 nominal data rate is 19 200 bits/s

ground base station: aeronautical station equipment, in the aeronautical mobile service, for use with an external
antenna and intended for use at a fixed location
integral antenna equipment: radio communications equipment with an antenna integrated into the equipment without
