FIELD: radio engineering, communication.SUBSTANCE: electromagnetic wave data transceiver device is designed for installation on a post and includes an antenna, an electronic module connected to the antenna and designed to transmit and receive data via electromagnetic wave signals converted by the antenna. The antenna is formed in a flexible band which may be curved in the longitudinal direction thereof, passing from an open position in which the flexible band is open at one end leaving an opening for the lateral passage of a post to a closed position in which the flexible band takes up a cylindrical form. The device also includes closing means for setting the closed position of the flexible band. The invention also provides a system formed by a plurality of said the transceiver devices installed on vertical portions of posts.EFFECT: providing data transceiving via through electromagnetic waves.16 cl, 9 dwg |
