Abstract

The following idea is about defining the objective functional specifications for a Wireless-to-HomePlug Interface Card (WHIC) that can be a key component of mobile computing, video and voice over IP for Home/Small Office WLAN systems. In Fig. 1 an overall system with its main components is shown. The bi-directional wired connectivity between the Modem and the PCs and printers is based on the 802.16 emerging standard Home Plug specifications, and supports Internet and PC-to-PC, or PC-to-Printer connections as well as VoIP calls, MP3 file transfers, digital television transfer, etc. The channel also can support streaming video on any of the Gateway-to-PC connections. For an average home/small office installation, the requirement for only one or two simultaneous communications channels is envisioned. The WHIC system will include one set of HomePlug interface chips and one set of wireless chips such as Bluetooth, 802.11b, 802.11a and any other Wireless LAN chips. The WHIC is intended to be incorporated as a sub-assembly in the HomePlug Adapter of all or some of the HomePlug shop vendors at some later date. Fig. 2 is the block diagram for the WHIC. The WHIC contains the complete communications module from MAC to antenna for the wireless interface and it is connected to the HomePlug for the wired interface. Antennas are located external to the module. The IC's (Integrated Circuit) on the card provide for the control, encryption/de-encryption, QAM (Quadrature Amplitude Modulation) for the downlink, QPSK (Quadrature Phase Shift Keying) demodulation for the up link, radio transceiver, and interface to a PCI bus or other interfaces. The control interface to the Gateway module is through an API (Application Programming Interface) command set, which functions as interpretive routines executed by the processor embedded within the digital IC of the module. Specifications for this functions API will be accomplished in collaboration and customized to the application needs of the customer.

The following idea is about defining the objective functional specifications for a Wireless-to-HomePlug Interface Card (WHIC) that can be a key component of mobile computing, video and voice over IP for Home/Small Office WLAN systems.

In Fig. 1 an overall system with its main components is shown. The bi-directional wired connectivity between the Modem and the PCs and printers is based on the 802.16 emerging standard Home Plug specifications, and supports Internet and PC-to-PC, or PC-to-Printer connections as well as VoIP calls, MP3 file transfers, digital television transfer, etc. The channel also can support streaming video on any of the Gateway-to-PC connections. For an average home/small office installation, the requirement for only one or two simultaneous communications channels is envisioned.

The WHIC system will include one set of HomePlug interface chips and one set of wireless chips such as Bluetooth, 802.11b, 802.11a and any other Wireless LAN chips. The WHIC is intended to be incorporated as a sub-assembly in the HomePlug Adapter of all or some of the HomePlug shop vendors at some later date. Fig. 2 is the block diagram for the WHIC. The WHIC contains the complete communications module from MAC to antenna for the wireless interface and it is connected to the HomePlug for the wired interface. Antennas are located external to the module. The IC's (Integrated Circuit) on the card provide for the control, encryption/de-encryption, QAM (Quadrature Amplitude Modulation) for the downlink, QPSK (Quadrature Phase Shift Keying) demodulation for the up link, radio transceiver, and interface to a PCI bus or other interfaces. The control interface to the Gateway module is through an API (Application Programming Interface) command set, which functions as interpretive routines executed by the processor embedded within the digital IC of the module. Specifications for this functions API will be accomplished in collaboration and customized to the application needs of the customer.

The WHIC supports all single channel 802.11a, 802.11b, Bluetooth, etc, emerging PHY (Physical Layer) rates. It shall enable operating data links between the DSL line and the PCs, or PC-to-PC, PC- to-Printer, home devices, and four independent and dedicated VoIP-to-phone lines. These communication links may be in any combination. In addition, this data link capacity can be dynamically re-prioritized allowing up to six MPEG2 streaming video links concurrent with at least five data links, while retaining twelve independent and dedicated VoIP-to-Phone lines.

The WHIC system shall differentiate between video streaming, MP3, data traffic and other Vo...
