Abstract: A system for monitoring television signals broadcast by at least one transmission antenna in a broadcast area includes a monitoring control center and a plurality of remote monitoring units distributed in television signal receiving locations of the broadcast area remote from the transmission antenna. The remote monitoring units are configured to receive the television signals irradiated in the respective locations, process the television signals and send to the monitoring control center information related to the processed television signal. In particular, the remote monitoring units include a receiver adapted to receive the television signal, a measuring system adapted to perform measures on radio-electric features of the received television signal, and a communication system adapted to communicate measurement results to the remote monitoring center, exploiting a communication link between the remote monitoring unit and the control center.

Abstract: A system and related device emulates the behavior of mobile networks independently from the manner of collecting data about the behavior of the network obtained through a simulation of field measurements. The system emulates the behavior of the network during the exchange of information between terminals and uses an emulation device comprising two circuit blocks. The first is able to process the information according to time sequences corresponding to those of mobile networks. The second one exchanges information between the terminals connected to suitable interfaces. This architecture makes it possible to emulate uplink and downlink functions of the mobile network, displaying on the terminals the effects of the behavior of the network under various operating conditions.

Abstract: The present invention relates to a system and related device for emulating the behaviour of mobile networks independently from the manners of collecting data about the behaviour of the network, be they obtained through a simulation of field measurements. The system emulates the behaviour of the network during the exchange of information between terminals and uses an emulation device (12) comprising two circuit blocks (20, 30) able, respectively, the first to process the information according to time sequences corresponding to those of mobile networks, the second one to exchange information between the terminals connected to suitable interfaces (35, 36). Thanks to the architecture described above it is possible to emulate uplink and downlink functions of the mobile network, making perceptible on the terminals the effects of the behaviour of the network in the various operating conditions.

Abstract: The present invention relates to a test plant (10) for digital mobile radio systems comprising one or more radio base stations (RBSs) (12), a corresponding base station controller (BSC) (11) and a testing apparatus (14) interposed between the RBSs (12) and the BSC (11). The test plant (10), and the testing apparatus (14) in particular, make it possible to check mobile radio system performance while allowing proprietary Operation & Maintenance messages to travel transparently between the RBSs (12) and The BSC (11), and generating, in the apparatus (14), radio protocol messages (Radio signaling Link messages) which in general constitute the portion of information on which testing is carried out and are organized in accordance with predetermined standards.
