ETSI EN 302 842-4:2010 VHF air-ground and air-air Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement for aeronautical mobile (airborne) equipment; Part 4: Point-to-point functions (V1.2.2)
"The present document applies to the following radio equipment types: ? 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 provides part 4 of the technical specifications. 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 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: ? clause 2 provides references to relevant documents; ? clause 3 provides general definitions@ abbreviations and symbols used; ? clause 4 describes the VDL Mode 4 mobile station point-to-point functions; ? clause 5 provides 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; ? annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4 Technical Manual [1]; ? annex B provides a bibliography; ? a document history. 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."
