ETSI ETSI EN 301 842-1 V1.3.2 (2010-12) 7 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]. SIST EN 301 842-1 V1.3.2:2011



ETSI ETSI EN 301 842-1 V1.3.2 (2010-12) 8 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; SIST EN 301 842-1 V1.3.2:2011



ETSI ETSI EN 301 842-1 V1.3.2 (2010-12) 9 • clause 7 provides general design requirements; • clause 8 covers general test conditions, environmental tests and calibration; • clause 9 provides detailed test procedures for the physical layer; • annex A provides a detailed cross-reference to the relevant requirements contained in reference [1]; • annex B provides a Bibliography; • a document history. The full physical layer tests are provided which correspond closely to the standard set of tests used for other VDL systems. 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. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies.
