In recent years there has been increasing demand for access to information systems and communication by e-mail for both office and home use, anywhere and anytime. As a first step, this was achieved by using an external modem terminal connected toa public telephone. However, the need arose for wireless data communication accompanying the popularization of the digital cellular phone system.To meet this need, we have developed the IPC0004A personal handy-phone (PHS) data communication card as an optional device for personal computers. The IPC0004A card enables wireless data communication to be realized using PHS, which can perform 32 kbpsdata transmission, and a DOS/V-based personal computer. This card will support the widespread diffusion of mobile computing capabilities.
