Abstract
A computer apparatus for receiving a removable communication card such as a radio card or a modem card. A radio or modem is self-contained inside a housing of the communication card and has an electrical interface for communicating information to and from the computer apparatus. The computer apparatus receives the communication card such that it engages the electrical interface. The computer apparatus additionally has at least one pair of electrical contacts which will encounter electrical contacts on the communication card. These contacts automatically connect the communication card to an appropriate antenna, telephone, telephone line or power source. A radio communication card is connected to the appropriate antenna for the type and frequency of the radio. A modem card is connected to a standard telephone line, a cellular phone, or an antenna for a cellular phone if the cellular phone is also disposed within the housing of the modem communication card.
