Benefits of technology

The present invention provides a method and apparatus for improving data transmission over a network by using additional secondary channels for the purposes of increasing overall data-rate, enhancing reliability, reducing transmit power, and extending range. The method involves configuring nodes to use the secondary channels and marking them as unusable channels to prevent access by legacy nodes. The apparatus includes a media access control processor, physical-layer processors, front-end devices, and a combining device for combining the outputs of the front-end devices. The method and apparatus can be used in various network environments and can provide high reliability, low transmit power, and extended range transmissions.

Problems solved by technology

Additionally, the standard [1] defines the concept of ‘taboo-channels’ which are channels on which if transmissions occur, devices in existing network may suffer from impaired operation.

Embodiment Construction

[0046]While originally conceived to service the needs of home networking taking advantage of the installed coax cable plant to distribute local-area-network (LAN) content within the home, MoCA has also been extended to several other applications. In a multi-dwelling unit (MDU) it has been envisioned that MoCA could be used as a point-to-multi-point means of distributing wide-area-network (WAN) content that arrives to the building over an optical-link to multiple tenants, exploiting the installed coaxial cable in the building. In another application scenario it is intended that MoCA be used to carry the WAN content from a curb-side optical network termination to an individual residence in a point-to-point configuration. These applications impose different rate / range performance requirements on the technology.

[0047]The systems, methods and apparatus embodied in following disclosure are collectively referred to as ‘Enhanced-MoCA’ or EMoCA, as well as all enhancements and variations whi...

Abstract

A technique for communicating multimedia data between nodes over coaxial cable, wherein the nodes are connected via a coaxial cable network, is disclosed. In an embodiment, the technique involves establishing a primary channel for communicating between first and second nodes of the coaxial cable network, establishing a secondary channel for communicating between the first and second nodes of the coaxial cable network, wherein the primary and secondary channels are in different frequency bands and wherein the primary channel is used for communicating media access control frames, and communicating a time series of data frames between the first and second nodes using both the primary channel and the secondary channel.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is entitled to the benefit of provisional U.S. Patent Application Ser. No. 60 / 978,012, filed Oct. 5, 2007, the disclosure of which is incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]Driven by the increasing prevalence of digital content and multi-media applications, of late there has been a dramatic growth in the need for home networking. This has fuelled new development of home networking technology both wired and wireless. One such technology—the Multimedia over Coax Alliance (MoCA) V1.0 Specification (identified herein as [1]) describes the MAC and PITY layers for high-rate communications over the coaxial TV-cable plant that is present in most homes. MoCA makes use of a 256-tone OFDM based-PHY to provide for a data-rate of up to 310 Mbps at a range of up to 300 feet on a 50 MHz channel located in the 850˜1500 MHz band. This translates to an effective MAC-layer throughput of 125 Mbps.[00...
