Companies Join Forces on IEEE P1905.1 Draft Standard; Unveil
   New Reference Design to Bring to Market MoCA-to-Wi-Fi Access
                        Points and Routers

LAS VEGAS, Jan. 11, 2012 (GLOBE NEWSWIRE) -- (INTERNATIONAL CONSUMER
ELECTRONICS SHOW 2012 -- BOOTH #31253) -- Entropic Communications, Inc.
(Nasdaq:ENTR), a leading provider of silicon and software solutions to
enable connected home entertainment, today announced its collaboration
with Qualcomm Atheros to deliver home networking solutions and products
based on the recently approved IEEE P1905.1 Draft Standard for
Convergent Digital Home Networks, which provides a single protocol for
unifying networks based on Ethernet, MoCA(R) (Multimedia Over Coax),
Wi-Fi and HomePlug Powerline. Networking products that take advantage
of a P1905.1-based architecture simplify the configuration and setup
complexity when using multiple types of network technologies in a
single home.

The companies are unveiling a joint reference design that enables
service providers and consumer electronics original equipment
manufacturers (OEMs) and original device manufacturers (ODMs) to build
home networking products that improve whole-home coverage by using the
MoCA network to extend the range of Wi-Fi. This reference design is the
first step toward leveraging the in-home MoCA network to automatically
authenticate and configure Wi-Fi Access Points (AP) into an extended
service set (the "auto-configuration" feature in P1905.1), enabling
seamless roaming of mobile client devices such as tablets, notebooks
and smartphones -- from AP-to-AP -- throughout the extended whole-home
Wi-Fi coverage area. Entropic and Qualcomm Atheros are collaborating to
make this solution fully compliant with the IEEE P1905.1 Draft
Standard.

"The convergence of broadcast and broadband content, especially video,
benefits from the smart usage of the leading wired and wireless media
available in the home," said Patrick Ribardiere, director of product
management, Qualcomm Atheros. "Through broad collaboration with
Entropic, we are enabling OEMs and operators to extend the range of
MoCA-enabled home networks by wirelessly connecting to any mobile,
computing or CE device throughout the home."

The reference design is built on Qualcomm Atheros' widely adopted
two-stream dual-band XSPAN 802.11N system-on-chip (SoC) with Entropic's
market leading MoCA-based silicon and software solution. With the
combined technologies, the reference design will enable service
providers and OEM/ODMs to deliver MoCA-to-Wi-Fi range extender products
that will create a high performance whole-home network using existing
coaxial cable infrastructure.

"In the United States, MoCA penetration is expected to exceed 25
million households by 2014, allowing existing MoCA home networks to
quickly expand," said Vinay Gokhale, senior vice president, Marketing
and Business Development, Entropic Communications. "The high throughput
and reliability offered through integrated Wi-Fi and MoCA networking
makes use of the strengths of each technology to support robust HD
streaming to tablets, smartphones, and other connected devices. Many
companies talk about overcoming convergence challenges, but Qualcomm
Atheros and Entropic are taking the lead to make this a reality."

Entropic will be demonstrating the MoCA-to-Wi-Fi reference design,
which incorporates Pre-1905.1 features during CES2012, booth #31253,
January 10-13, 2012, in Las Vegas. The reference design will be
available in Q1 2012.
