• dodatek A, ki podaja podrobno sklicevanje na ustrezne zahteve, zajete v sklicu [1],
• dodatek B, ki podaja bibliografijo,
• zgodovino dokumenta.
Podani so celotni preskusi fizične plasti, ki zelo ustrezajo standardnemu sklopu preskusov, uporabljenih za druge sisteme VDL.
Fraze, ki zahtevajo in ki priporočajo:
a) »Mora«
Uporaba besede »mora« nakazuje obvezen kriterij; npr. skladnost z določenim postopkom ali specifikacijo je obvezna in nobena druga možnost se ne sme uporabiti.
b) »Naj«
Uporaba besede »naj« (in fraze, kot je »Priporoča se, da …« itd.) nakazuje, da čeprav se postopek ali merilo šteje za prednostno možnost, se lahko uporabijo drugi postopki, specifikacije ali merila, pod pogojem, da proizvajalec, monter ali preskuševalec lahko zagotovijo informacije ali podatke, s katerimi ustrezno podprejo in upravičijo drugo možnost.

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 [i.1]. The
modular structure is shown in EG 201 399 [i.2].
The present document states the technical specifications 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
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].

1 Scope
The present document applies to the following radio equipment types:
• 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 1 of the technical specification.
The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAO
VHF Digital Link (VDL) Standards and Recommended Practices (SARPs) [2] and VDL Mode 4 Technical Manual
(TM) [1].
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 [8].
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 deals with tests of the physical layer necessary to support all types of equipment.
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 [7];
• clause 5 provides functional specifications applicable to the physical layer including transmitter/receiver
requirements and the modulation scheme;
• clause 6 provides general equipment requirements;
