摘要
A PCMCIA cellular card provides both cellular audio and data communication. Specifically, the PCMCIA cellular card is configured to operate in either a cellular phone handset or in a portable computer. The PCMCIA card includes a baseband portion (403) for providing digital signal processing for both audio and data, an intermediate/radio frequency portion (405, 411) for signal modulation/demodulation and radio signal transmission/receipt, a PCMCIA interface (401) serving as a communicator between the PCMCIA cellular card and the peripheral devices, i.e. the cellular phone handset and the portable computer, and a controller portion (402) for controlling the whole system. Therefore, when an individual travels, the individual is able to either take the cellular phone handset, with the PCMCIA cellular card contained therein (thereby converting the cellular phone handset to a regular cellular phone), or take the portable computer with the PCMCIA communication card installed therein for use with the computer as a modem and a telephone. If an individual takes both the cellular phone handset and the portable computer, only one battery charger is required, thereby saving weight.
