A wireless communication terminal includes a SIM card and a memory card equipped with respective radio transceivers for allowing a terminal-independent and network-independent radio communication between both cards. Server and client applications on the controllers of the transceivers allow the SIM to manage the memory card. The memory card tries to become connected to the SIM. If connection is successful, the SIM authenticates the memory card and then configures it, in secure mode, to set the access policy to the memory card itself.

Method for the management of a peripheral unit by a sim card in wireless communication terminals, and peripheral unit for implementing the method

A system for automating parking payment including user terminals having wireless communication equipment allowing access to a wireless communication network and including readers/writers of electronic tags, electronic tags to be carried by the users on their vehicles and into which the users can input information concerning a parking event by means of their terminals; and a parking service management center connected to said network.

System for and method of automating parking payment by using electronic tags

An integrated device transmits and/or receives information by means of millimetric waves (wavelength 1 mm-10 mm), frequencies of 30 to 300 Ghz. The device has an optoelectronic integrated circuit that interfaces with an antenna able to transmit and/or receive millimeter wave signals. The device forms a transceiver module to be used in a wireless or mobile radio local area network. The transmitter circuit is constituted by a laser in passive mode-locking. The receiver circuit is constituted by an antenna, a photodiode, and a laser identical to that of the transmitter. The photodiode, by means of appropriate bias, performs a dual function of optical and electrical mixer. In particular, the first function converts to electrical frequency the optical beat signal between two modes generated by the laser, the second function allows the received signal to be brought back to base band, thereby allowing the extraction of the modulating signal from the weak signal received through the antenna.

Millimeter wave transmitter using optical heterodyning

The process and apparatus to enable measurement of polarization dispersion of a single-mode optical fibre by launching measurement light at one end of the fibre and analyzing polarization of the light reflected by the other end and collected at such launch end. Optical or electronic masking of light reflected by the near end of the fibre is performed during launch.

Process and apparatus for measuring polarization dispersion in optical fibers

A method of and an apparatus for measuring return loss in an optical fiber component. Radiation of a predetermined wavelength, e.g. from a laser, is launched into an optical fiber component, preferably through an optical fiber having a polarization control loop and the radiation reflected and the direct radiation are subjected to phase modification. An amplitude of the frequency component of the detected signal at the frequency imposed by phase modulation is measured and is used as the basis for evaluating the return loss.
