CopperGate's CopperStream™ Technology
CopperGate’s CopperStream™ technology exploits the capacity of telephony and coax wiring by delivering data rates of up to 320 Mbps to multiple network nodes.
The CopperStream™ technology includes a robust Quadrature Amplitude Modulation (QAM) scheme, which achieves high data rates on a variety of wiring topologies, overcomes various impairments and coexists with other services on the same wires, such as POTS, dial-up modems, ISDN, ADSL, VDSL and broadcast TV. It also features a highly efficient synchronous Media Access Control (MAC) protocol layer that enables a useable net throughput of above 200Mbps. The technology is capable of guaranteeing the required Quality of Service (QoS) for multiple simultaneous streams, essential in entertainment and multimedia applications and services such as distribution of multiple HDTV streams, distribution of multiple IPTV streams, digital audio and toll-quality voice streams within the home. Also part of the CopperStream™ technology are a Convergence Layer that supports bridging to external broadband networks and protocols such as xDSL, DOCSIS, IEEE 802.16, IEEE1394, and a suite of management and diagnostic functions.
Major elements of the CopperStream™ technology have been selected as the foundation of the ITU G.9954 home networking standard. The technology was also selected as the HomePNA V3.1 standard, sanctioned by the HomePNA Alliance. Building on the knowledge base and experience gained from earlier versions of the standard, HomePNA V3.1 provides the best cost/performance solution for “no-new-wires” home networking applications. CopperGate’s chipsets comply fully with ITU G.9954 and with the HomePNA V3.1 standards.
