A distributed modem in order to achieve non-cellular cordless/wireless data communications for portable computers is described. In one embodiment, the modem includes three components, a digital signal processor (DSP), a coder/decoder (CODEC), and a digital-access arrangement (DAA). The DSP resides within a PCMCIA card for insertion into a computer. The CODEC and the DAA reside on a base station. The PCMCIA card and the base station communicate with one another via two transceivers, one each at the PCMCIA card and the base station.
