摘要:
A radio coverage extender is provided for extending the radio range of a wireless network node embedded in a user terminal, for example a ZigBee node integrated on the SIM card of a mobile phone. The radio coverage extender may include: a radio signal repeater operable to receive radio signals from the wireless network node and to retransmit the received signals externally to the user terminal, and a power supply module operable to scavenge electrical energy from electromagnetic fields in which it happens to be immersed and to store the scavenged electrical energy for supplying the stored power to the radio signal repeater. The radio coverage extender is adapted to be included in a user terminal, for example it can be a flexible, pliable film attachable to a user terminal battery.

A subscriber identification card performing radio transceiver functionality for long-range applications incorporates a radio transceiver including an antenna formed on a card surface, an RF module and a base-band module. The antenna and the transceiver operate in the microwave/millimetre waves frequency range. This allows meeting the dimensional constraints imposed by the plug-in size and attaining a long-range operation. At least the base-band module might be integrated within the same chip executing standard security related functions for the terminal.

A system includes a plurality of networked nodes spatially distributed within a monitored area and adapted to interact with a mobile entity entering and moving through the area, the plurality of nodes including at least one area entrance node adapted to detect the mobile entity upon entering the monitored area, and a transaction node for accomplishing a transaction with the mobile entity; a transaction processing center in communication relationship with the nodes for processing data required for the transaction and for providing the data to the transaction node. A node selection unit is adapted to dynamically select the transaction node among the plurality of nodes based on an estimation of the speed of movement of the mobile entity.

An integrated circuit card for a mobile terminal incorporates a radio transceiver module intended for communications that do not pass through the mobile network. To allow using, for the chip of the IC card and the radio transceiver module, the same chips as would be used for conventional IC cards and transceivers not integrated together, the IC card further includes a finite state machine chip interconnecting the IC card chip and the chip(s) of the transceiver module so that they have access to the card contacts establishing connection between the card and the terminal.

摘要:
To reduce energy consumption in a duty-cycled asynchronous wireless communication network values of operation parameters, i.e. duration of the awake interval and duration of the sleep interval, of routing nodes of the network are determined and set. The network is partitioned into clusters so that each cluster comprises one cluster-head node. The energy consumption of a cluster is a function of the probability of busy channel when nodes of the cluster attempt transmission, the probability of communication collision during transmission, the duration of the awake interval and the duration of the sleep interval of its cluster-head node. Reduction of the energy consumption is carried out under predetermined values of the probability of busy channel and of the probability of communication collision and under predetermined constraint for the probability of successful transfer of data packets within the cluster and for the average delay of transfer of data packets within the cluster.
摘要:
A system for automatic identification of a device or appliance includes: at least one sensor associatable with the device or appliance to be identified, and able to monitor an evolution in time of an electrical quantity indicative of device or appliance energy consumption; an analyzer communicating with the at least one sensor including receiving reports of the monitored electrical quantity, and automatically identifying the device or appliance by analyzing the evolution in time of the monitored electric quantity. The analyzing calculates a cross-correlation between the evolution in time of the monitored electric quantity and at least one reference pattern representative of at least one sample device or appliance; and when more than one sample device or appliance is included in a candidate list, identifies the device or appliance by performing a selection among the candidates based on characteristic parameters related to the respective calculated cross-correlations.
