Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices; Road Transport and Traffic Telematics (RTTT); Radar equipment operating in the 76 GHz to 77 GHz range; Part 2: Harmonised EN covering essential requirements of article 3.2 of the R&TTE Directive
ETSI EN 301 091-2 V1.2.2 (2005-07)

The present document applies to Road Transport Traffic and Telematics (RTTT) systems:
• with an integral antenna;
• for mobile applications only;
• operating in the frequency range from 76 GHz to 77 GHz.
The applicability of the present document covers only the 76 GHz to 77 GHz Radar equipment for road vehicles. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to radio equipment intended to operate in a frequency designation as defined in CEPT/ECC/DEC (02)01 [7] and in CEPT/ERC/REC 70-03 [5] in all or in part of the service frequency band from 76 GHz to 77 GHz.
The present document is intended to cover the provisions of Directive 1999/5/EC [1] (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". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive [1] will apply to equipment within the scope of the present document.

Electromagnetic compatibility and Radio spectrum Matters (ERM); Technical characteristics and methods of measurement for shipborne watchkeeping receivers for reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and VHF bands
ETSI EN 301 033 V1.2.1 (2005-12)

The present document states the minimum operational and performance requirements for shipborne receivers intended to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the maritime mobile service, both in connection with distress and safety communication and in connection with general communication.
These requirements include the relevant provisions of the ITU Radio Regulations [1], ITU-R Recommendations M.493-11 [3], M.541-9 [11], M.489-2 [10] and the IMO Resolutions A.803(19), A.804(19), A.806(19) and A.694(17). The present document specifies also technical characteristics, methods of testing and required test results for dedicated watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS. It covers both receivers with analogue output or with digital DSC signal output interfaces or with both. DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment. For integrated equipment the present document specifies the requirements and methods of testing of the DSC watchkeeping receivers only. DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers. Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338 [13], EN 300 162-1 [12] and EN 300 373-1 [14] respectively.

Electromagnetic compatibility and Radio spectrum Matters (ERM); VHF air-ground Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement for ground-based equipment; Part 2: General description and data link layer
ETSI EN 301 842-2 V1.4.1 (2005-04)

The present document provides part 2 of the technical specifications for 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) [14]. 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) [14] 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 [13].
The VDL Mode 4 system provides data communication exchanges between aircraft and ground based systems 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-to-air, air-to-ground, ground-to-air and ground mobile services;
• operation without ground infrastructure.
VDL Mode 4 is designed to be an Air/Ground subsystem of the Aeronautical Telecommunication Network (ATN) [8] using the AM(R)S band and it is organized according to the Open Systems Interconnection (OSI) model (defined by ISO). It provides reliable sub network services to the ATN system. Other networks can also be supported but these have not been focussed on in the present document.
The present document specifies functional specifications of VHF communication ground station equipment intended to be used for air-ground and air-air data communications. The present document is derived from the standards and specifications in:
• VDL Mode 4 standards produced under the auspices of the International Civil Aviation Organization (ICAO) [1].
• 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.
EN 301 842-1 [4] deals with tests of the physical layer. The present document defines the core link layer requirements for the VDL Mode 4 ground station necessary to support all types of equipment. This includes a simple position broadcast functionality.

ETSI EN 302 066-1 V1.1.1 (2005-06)

The present document specifies the requirements for Ground- and Wall- Probing Radar applications operating in all or part of the frequency band from 30 MHz to 12,4 GHz. Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications. The scope is limited to radars operated as short range devices (because of their usage and design), in which the system is in close proximity to the materials being investigated. It does not include radars operated from aircraft or spacecraft. The radar applications in the present document are not intended for communications purposes. Their intended usage excludes radiation into the free space and means shall be taken to keep it to a minimum.
NOTE 1: Equipment using the frequencies typically below 100 MHz may use higher output power for geophysical applications and therefore, may not fulfil the emission requirements set out in the present document.
NOTE 2: Equipment covered by the present document is used by competent professional personnel. The present document applies to:
1) Ground Probing Radars (GPR) operating over approximately one decade in the frequency range 30 MHz to 12,4 GHz radiating directly downwards into the ground. Any horizontal radiation from this equipment is caused by leakage and is considered as undesired emission.
2) Wall Probing Radars (WPR) operating in the frequency range 30 MHz to 12,4 GHz radiating directly into a "wall". The "wall" is a building material structure, the side of a bridge, the wall of a mine or another physical structure that absorbs a significant part of the signal transmitted by the radar.
3) Equipment fitted with integral antennas and without antenna connector.
4) Equipment which uses different imaging heads (antennas) with an antenna connector, to allow operation at different frequencies.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable. The present document contains the technical characteristics and test methods for Ground- and Wall- Probing Radar applications.

ETSI EN 302 842-4 V1.1.1 (2005-05)

The present document provides part 4 of the technical specifications for Very High Frequency (VHF) Digital Link (VDL) Mode 4 aeronautical mobile (airborne) radio transmitters, transceivers and receivers for air-ground and air-air 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 VDL SARPs [2]. The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAO VDL SARPs [2] and ICAO VDL4 Technical Manual [1]. Manufacturers should note that in future the tuning range for the transmitter may also cover any 25 kHz channel from 112,000 MHz to 117,975 MHz and the receiver(s) may cover any 25 kHz channel from 108,000 MHz to 117,975 MHz. The present document applies to "aeronautical mobile (airborne and as applicable also ground vehicles)" equipment which will hereinafter be referred to as "mobile" equipment. The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is EN 301 842 [4]. A description of the scope of the VDL Mode 4 system is provided in part 2 of these technical specifications (see EN 302 842-2 [6], clause 1). EN 302 842-1 [5] deals with tests of the physical layer, EN 302 842-2 [6] deals with core link layer functionality and EN 302 842-3 [7] with additional broadcast functionality. The present document deals with tests of the datalink layer (DLS) and the link layer sufficient to support point-to-point functionality. Note that, as described in EN 302 842-2 [6], a system supporting point-to-point functionality is required to conform to EN 302 842-1 [5], EN 302 842-2 [6] and the specification in the present document.
The present document includes:
• references, definitions and abbreviations are provided in clauses 2 and 3;
• clause 4 describes the VDL Mode 4 mobile station point-to-point functions;
• clause 5 performance specifications for the VDL Mode 4 mobile station;
• clause 6 provides general design requirements;
• clause 7 provides protocol tests for the point-to-point functions of the system;
• a document history is contained in clause 8;
• annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4 Technical Manual [1].
Note that the system can support a very wide range of functions. It is not practical to provide specific tests for all aspects of functionality. The approach used is to provide detailed tests for the core point-to-point functionality and to provide tests of those remaining requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations.
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.) indicates 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.
