FIELD: wireless communications.SUBSTANCE: invention relates to an onboard data system with mobile radio communication antenna (2) for detecting at least one relevant for the vehicle parameter. Technical result is improved characteristics of radiation and reception of the mobile radio antenna even when assembling the said antenna in the inner space of the vehicle. Said technical result is achieved by that the proposed system comprises built in the inner space of the vehicle body (1) and a mobile radio communication module. Mobile radio antenna (2) is arranged in recess (3) of body (1), and its radiating surface (4) is located at a distance from body (1).EFFECT: proposed system can be used, in particular, in a vehicle as a tachograph, primarily as a digital tachograph, and/or as a device for registering a road due.36 cl, 7 dwg |
