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 (1) incorporates a radio transceiver (3, 4, 5) including an antenna (3) formed on a card surface, an RF module (4) and a base-band module (5). The antenna (3) and the transceiver (4) 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 (5) might be integrated within the same chip (2) executing standard security related functions for the terminal.
