Abstract
A computer system having transceivers coupled to USB ports so as to provide a wireless USB bus between a computer and one or more peripheral devices is disclosed. The transceivers allows the computer to be remotely located from the peripheral devices (e.g., USB devices) by distances substantially greater than five (5) meters, and thus overcomes the five (5) meter limitation on cable length for a USB bus that burdened the conventional wired USB buses. The power utilization of the transceiver is also managed so as to comply with the USB specifications. In one embodiment, the transceivers are radio frequency (RF) transceivers.

39. A radio frequency transceiver apparatus for providing a wireless USB bus, comprising:
-
a USB connector for connecting to a hosting device;
a USB interface electrically connected to the USB connector;
a radio frequency transceiver electrically connected to the USB interface, the transceiver to transmit and receive radio frequency signals; and
an antenna operatively connected to the transceiver, wherein the transceiver comprises;
a modulator to modulate digital signals to be transmitted to produce analog signals of a first frequency;
an up-converter operatively connected between the modulator and the antenna, the up-converter to convert the analog signals of the first frequency to analog signals of a second frequency that is higher than the first frequency, and to supply the signals of the second frequency to the antenna;
a down-converter to receive incoming analog signals of the second frequency from the antenna and to convert the incoming analog signals to incoming analog signals of the first frequency that is lower than the second frequency; and
a demodulator operatively connected to the down-converter, the demodulator to demodulate the incoming analog signals to obtain incoming digital signals. - View Dependent Claims (40, 41, 42)
