DEVICE FOR TRANSMITTING/RECEIVING DATA BY MEANS OF ELECTROMAGNETIC WAVES, AND SYSTEM WHICH COMPRISES A PLURALITY OF SAID DEVICES

摘要

Device for transmitting/receiving data by means of electromagnetic waves which is suitable for installation on a post (1). Said device comprises an antenna (2) and an electronic module which is connected to the antenna (2) and is suitable for sending and receiving data by means of electromagnetic wave signals transduced by the antenna (2). The antenna (2) is formed in a flexible band (4) which may be bent in the longitudinal direction thereof, moving from an open position, in which the flexible band (4) is open at one end, leaving an opening for the lateral passage of a post (1), to a closed position in which the flexible band (4) embraces a cylindrical shape. The device comprises closure means (5, 6) for fixing the closed position of the flexible band (4). The invention also comprises a system formed by a plurality of said devices for transmitting/receiving data which are installed in vertical sections of a number of posts (1).
