Abstract:
A telecommunications network for mobile phone users (UNET) comprising a user subsystem (STU) and a transport subsystem (STT) associated by means of an access subsystem (STA), which connect to them respectively through a user access communication interface (Vu) and a transport access communication interface (fu) suitable to allow the exchange of data flows (TS) between said subsystems, the access subsystem (STA) identifying a coverage area of the telecommunication network for mobile users (UNET) characterized in that said access subsystem determines on the territory a separated cellular coverage for the transmission (uplink) from the user subsystem (STU) to the network with respect to that from the network to the user subsystem (STU), said access subsystem STA) being composed from, in addition to bidirectional base stations (SNB), as known, also from stations suitable to support monodirectional transmission in uplink (SNBu) or in downlink (SNBd).
Abstract:
A telecommunications network for mobile users of the third generation, said (telecommunications network for mobile users (UNET) comprising a user subsystem (STU) and a transport subsystem (STT), associated by means of an access subsystem (STA), which has a general user-access communication interface (Vu) and a transport-access communication interface (Iu) facing them, respectively, being apt to ensure an exchange of information flows (TS) between said subsystems. According to the invention, the user subsystems (STU) can associate to the access subsystem (STA) with a communication through telecommunications cables, i.e. not only with radio communications as indicated in the various standards (such as those of the family IMT2000) and various patterns suggested for obtaining mobile telecommunications networks of the third generation.
Abstract:
A telecommunications network for mobile users (UNET), said telecommunications network for mobile users comprising a user's subsystem (STU) and a transport subsystem (STT) connected by means of an access subsystem (STA), which offers them respectively a user access communications interface (Uu) and a transport access communications interface (lu), suitable to permit the exchange of the information flows (TS) among said subsystems, said access subsystem (STA) identifying a coverage area of the cellular telephone network. According to the invention, said access subsystem (AST) is associated with interconnection means (GSB, NGS) in order to receive second flows of information (BS) broadcast from one or more geostationary satellites (GS) and send them via the telecommunications network for mobile users (UNET), said means of interconnection (GSB, NGS) being located within the coverage area of said mobile telecommunications network (UNET).

Abstract:
The present invention relates to a radiator (1) of the type comprising: - a first surface (10) adapted to be associated with a hot system (11), in particular to adhere to at least one portion of said hot system (11); - at least one fin (20) extending from said first surface (10) in a manner such as to increase the area of the radiator (1) that comes into thermal contact with the surrounding fluid. The invention is characterised in that said radiator (1) comprises conversion means (20, 30) adapted to convert the thermal energy that must be removed from the hot system (11) into electric energy, said conversion means consisting of at least one thermocouple comprising: - a first conductive element consisting of the fin (20) of the radiator (1), and - a second conductive element comprising at least one component (30) associated with said radiator (1) in a manner such as to extend within said at least one fin (20),
said at least one component (30) being made of a material having different thermoelectric characteristics, in particular a different Seebeck coefficient, than the radiator (1), in particular than the first surface (10) and/or the fin (20) thereof.
