Abstract

The invention relates to an assembly for radio communication containing all the electronic components necessary for radio transmission/reception, which can alternatively be connected to a device for voice communication and to a device for data communication.

The device for voice communication with the assembly (which, according to the preferred embodiment of the invention, is implemented on a reduced dimension PCMCIA integrated circuit card) plugged therein, has more or less the same dimension and the same weight of a usual cellular phone device.

When radio data transmission is desired the PCMCIA integrated circuit card is to be unplugged from the telephone handset and plugged into a data processing device properly arranged. In this way the data processing device is provided with the capability of radio transmitting and receiving data.

Claims

1. An adapter comprising:

a transmitter for transmitting radio signals;

a receiver for receiving radio signals;

a first interface means for outputting digital data from the adapter and for inputting digital data to the adapter;

a modem providing analog signals for transmission by the transmitter from digital data obtained by the first interface means and for providing digital data to the first interface means from analog signals obtained from the receiver;

a second interface means for outputting analog signals from the adapter obtained directly from the receiver and for inputting analog signals to the adapter directly to the transmitter; and

a control module for configuring the adapter to enable communication via the first interface means or the second interface means, said control module selecting the first interface means or the second interface means based upon a specified mode of operation obtained via the first interface means.

2. The adapter of claim 1 wherein the first interface means is in compliance with a PCMCIA standard.
