Abstract
In one embodiment of the present invention, a wireless USB architecture includes a transmitting device and a receiving device. The transmitting device includes a USB port to which a USB peripheral device can be connected, a conversion circuit for translating from USB protocol to RF protocol, and an RF transmitter for transmitting RF signals to the receiving device. The receiving device includes an RF receiver, a conversion circuit for translating from RF protocol to USB protocol, and a USB port which can be connected to the USB port of a computer.
Claims19
An apparatus to support wireless communications with a USB peripheral comprising
- a receiver to receive wireless signals,
- a first conversion circuit coupled to the receiver to convert the received wireless signals from a wireless protocol to USB signals having a USB protocol,
- a USB port to provide the USB peripheral with the USB signals generated by the first conversion circuit and to receive USB signals from the USB peripheral coupled to the USB port,
- a transmitter to transmit wireless signals having the wireless protocol,
- a second conversion circuit coupled to the transmitter to convert the USB signals received from the USB peripheral from the USB protocol to the wireless protocol to be transmitted by the transmitter,
- an antenna coupled the receiver and the transmitter via an antenna port to receive and transmit the wireless signals, and
- a power port to supply the apparatus with power from a battery power source.
A method of communicating between a computer and a USB peripheral comprising
- powering the USB peripheral via a battery power source of a first device,
- transmitting USB packets from the USB peripheral to the first device via a first USB cable,
- converting in the first device the USB packets to RF protocol packets,
- transmitting the RF protocol packets with an antenna of the first device,
- receiving the RF protocol packets with an antenna of a second device,
- converting in the second device the RF protocol packets to USB packets, and
- transmitting the USB packets from the second device to the computer via a second USB cable.
A system comprising
- a computer comprising a USB port,
- a first wireless communications device coupled to the USB port of the computer via a first USB cable to receive USB packets from the computer, the first wireless communications device to converter the USB packets to RF protocol packets and to transmit the RF protocol packets via an antenna of the first wireless communications device,
- a peripheral device comprising a USB port, and
- a second wireless communications device coupled to the USB port of the peripheral device via a second USB cable, the second wireless communications device to receive RF protocol packets via an antenna of the second wireless communications device, to convert the RF protocol packets to USB packets, to provide the peripheral device with the USB packets via the second USB cable, and to power the peripheral device via the second USB cable.
