Abstract: The invention relates to a device for radiofrequency communication in urban or road environments, comprising a luminaire of common use in street lighting which incorporates at least one transceiver with at least one data input and at least one data output coming from one or more antennas that operate in the radiofrequency band. The aforementioned type of light provides a suitable solution in terms of housing, electrical power supply, height and distribution for the respective transceivers owing to the design and usual arrangement thereof in urban or road environments. This way, the resulting assembly is particularly suitable for the provision of information-based services in general, and for the transmission of data in particular, in a communications system where the different nodes communicate with one another and with the user terminals.
