An electromagnetic wave data transceiver device suitable for installation on a post (1). It comprises an antenna (2) and an electronic module connected to the antenna (2) and suitable to send and receive data by way of electromagnetic wave signals transduced by the antenna (2). The antenna (2) is formed in a flexible band (4) which may be curved in the longitudinal direction thereof, passing 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 form. The device comprises closing means (5, 6) for setting the closed position of the flexible band (4). The invention also comprises a system formed by a plurality of said transceiver devices installed on vertical portions of posts (1). |
