Abstract
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.
Claims20
A computerized system comprising:
- a computer including a first radio frequency (RF) receiver;
- a base station including a second radio frequency (RF) receiver communicatively corresponding to the first RF transceiver;
- and,
- a modem distributed over the computer and the base station such that a first part of the modem resides within the computer and a second part of the modem resides within the base station,
- wherein the first part of the modem communicates with the second part of the modem via the first and the second RF receivers.
A computerized system comprising:
- a computer including a digital signal processor (DSP) adapted to modem communications and a first radio frequency (RF) transceiver operatively coupled to the DSP;
- and,
- a base station including a coder/decoder (CODEC) and a digital-access arrangement (DAA), the CODEC and the DAA adapted to modem communications corresponding with the DSP, the base station also including a second radio frequency (RF) transceiver operatively coupled to the CODEC and the DAA and communicatively corresponding to the first RF transceiver.
A hardware card for removable insertion into a corresponding slot of a computer comprising:
- a first radio frequency (RF) transceiver;
- a first part of a modem operatively coupled to the first RF transceiver and corresponding to a second part of the modem residing within a base station,
- wherein the first part of the modem communicates with the second part of the modem via the first and the second RF receivers.
A hardware card for removable insertion into a corresponding slot of a computer comprising:
- a first radio frequency (RF) transceiver communicatively corresponding to a second radio frequency (RF) transceiver of a base station, the base station also including a coder/decoder (CODEC) and a digital-access arrangement (DAA) adapted to modem communications;
- and,
- a digital signal processor (DSP) operatively coupled to the first RF transceiver and adapted to modem communications corresponding with the CODEC and the DAA.
