Subscriber Identification Card Performing Radio Transceiver Functionality for Long Range Applications

摘要

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.
