The present document applies to 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 112,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL) Standards and

Proizvajalci naj upoštevajo, da lahko razpon uravnavanja za talne oddajnike-sprejemnike v prihodnje zajema tudi kateri koli kanal 25 kHz od 108,000 MHz do 111,975 MHz.
Ta dokument vsebuje zahteve, s katerimi se dokazuje, da »... mora biti radijska oprema sestavljena tako, da učinkovito uporablja in tudi podpira učinkovito rabo radijskega spektra z namenom preprečevanja škodljivih motenj« [i.2].
Poleg tega dokumenta se za opremo na področju uporabe tega dokumenta uporabljajo tudi drugi standardi EN, ki določajo tehnične zahteve v zvezi z bistvenimi zahtevami iz drugih delov člena 3 direktive 2014/53/EU [i.2], ter tudi bistvene zahteve iz uredbe o interoperabilnosti enotnega evropskega neba 552/2004 [i.10] in zadevna izvedbena pravila in/ali bistvene zahteve iz uredbe EASA št. 216/2008 [i.3], kakor je bila spremenjena z uredbo št. 1108/2009 [i.4].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in the Radio Equipment Directive [i.2],
ISO/IEC 7498-1 [i.6], ISO/IEC 10731 [i.7] 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.
Bit Error Rate (BER): ratio between the number of erroneous bits received and the total number of bits received
data rate: maximum amount of data that can be transmitted in a specified amount of time, typically expressed as bits
per second
NOTE: The nominal data rate for VDL Mode 4 is 19 200 bits/s.

environmental profile: range of environmental conditions under which equipment within the scope of the present
document is required to comply with the provisions of the present document
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
the use of an external connector and considered to be part of the equipment
NOTE: An integral antenna may be internal or external to the equipment. In equipment of this type, a 50 Ω RF
connection point is provided for test purposes.
non-integral antenna equipment: radio communications equipment with a connector intended for connection to an
antenna
radiated measurements: measurements which involve the measurement of a radiated field
reference signal level: signal level used in the receiver performance specifications except otherwise stated
spurious emissions: conducted RF emissions on a frequency or frequencies which are outside the necessary bandwidth
and the level of which may be reduced without affecting the corresponding transmission of information
NOTE: Spurious emissions include parasitic emissions, intermodulation products and frequency conversion
products.
station: VDL Mode 4 Specific Services (VSS)-capable entity
NOTE: A station may be either a mobile station or a ground station. A station is a physical entity that transmits
and receives bursts over the RF interface (either A/G or A/A) and comprises, at a minimum: a physical
layer, media access control sublayer, and a unique VSS address. A station which is also a DLS station has
the same address.
VDL Mode 4: VHF data link using a Gaussian Filtered Frequency Shift Keying modulation scheme and self-organizing
time division multiple access
VDL Mode 4 station: physical entity that transmits and receives VDL Mode 4 bursts over the RF interface (either A/G
or A/A) and comprises, as a minimum: a physical layer, Media Access Control sublayer and a VSS sublayer
NOTE: A VDL Mode 4 station may either be a mobile VDL Mode 4 station or a ground VDL Mode 4 station.
VDL Station: VDL-capable entity that transmits and receives VDL bursts over the RF interface (either A/G or A/A)
and comprises, as a minimum: a physical layer, Media Access Control sublayer and a VSS sublayer
NOTE: A station may either be a mobile station or a ground station. A station is a physical entity that transmits
and receives frames over the air/ground (A/G) interface and comprises, at a minimum: a physical layer,
media access control sublayer, and a unique DLS address. The particular initiating process (i.e. DLE or
LME) in the station cannot be determined by the source DLS address. The particular destination process
cannot be determined by the destination DLS address. These can be determined only by the context of
these frames as well as the current operational state of the DLEs.
VDL System: VDL-capable entity comprising one or more stations and the associated VDL management entity
NOTE: A system may either be a mobile system or a ground system.
