SMC NETWORKS COLLABORATES WITH INTEL, Entropic Communications TO DELIVER FUTUre moCA® 2.0-BASED DOCSIS® 3.0 gateway SOLUTIONS

First Live Demo of Technology Collaboration Showcases How Service Providers Can Quickly Migrate to DOCSIS 3.0 Data Gateways with MoCA 2.0; Paving the Way for Higher Performance Home Entertainment Solutions to be Delivered Today

KEYSTONE, CO, (CableLabs® Summer Conference), August 8, 2011 — Entropic Communications, Inc. (Nasdaq: ENTR), a leading provider of silicon and software solutions to enable connected home entertainment, along with SMC Networks and Intel (Nasdaq: INTC), today announced their technology collaboration to accelerate the development of a new class of industry-first MoCA® (Multimedia over Coax) 2.0-enabled DOCSIS® 3.0 gateways for service providers.

As service providers look to deliver faster broadband speeds to enable future services and applications, the need to distribute this bandwidth around the home becomes increasingly more important. The cooperation between Entropic, SMC and Intel leverages the power of Intel's Puma™ 5 family of DOCSIS 3.0 cable modems, SMC's expertise in producing advanced DOCSIS data gateways and Entropic's complete MoCA 2.0 silicon and software solution to enable an unprecedented level of performance that can be delivered over coax cables for next-generation home entertainment services. By combining the unparalleled performance of MoCA 2.0 with Intel's DOCSIS 3.0 Gateway Linux-based System-on-a-Chip (SoC) and SMC's market leading DOCSIS 3.0 gateway, service providers can deploy a future-proof, cost-effective, robust, highly-reliable solution that delivers high-quality, advanced services and new applications throughout the home—without the worry of bandwidth constraints.

Building upon the success of MoCA 1.1, MoCA 2.0 provides a leap in bandwidth, delivering more than 400 Mbps of application throughput, thereby enabling next generation connected home entertainment services. MoCA 2.0 delivers a 'no excuses' whole-home network that can be used for distributing broadband bandwidth around the home, transporting high definition (HD) IP video and other streaming media services—all over existing coax. For the majority of North American service providers that are already using MoCA 1.1, MoCA 2.0 is fully backwards interoperable with prior MoCA standards, allowing original equipment manufacturers and service providers to easily transition and quickly deploy advanced gateway solutions to bring new services on line.

In the first public unveiling of its MoCA 2.0 silicon with DOCSIS gateways, Entropic will be demonstrating the MoCA 2.0-enabled DOCSIS 3.0 gateway with SMC and Intel at CableLabs Summer 2011, held August 8-9, in Keystone, Colorado.
