Screen Shot 2012-01-05 at 12.32.55 PMSigma Designs, today announced a unique set-top box (STB) reference design with Quantenna's high performance 802.11n 4x4 MIMO technology that enables Sigma's STB to receive video wirelessly and still meet the strict requirements for quality, robustness and reliability service providers demand.

Best In Class Wireless and Media Processor

The new platform combines Quantenna's industry acclaimed 802.11n QHS710 solution with Sigma's highly integrated 8652 connected media platform technology. This joint design will provide the best-in-class wireless and media processor combination on the market.

"By adding Quantenna's highly reliable Wi-Fi video delivery to our portfolio, we now can provide our customers with the most complete connectivity solution in the industry," said Thinh Tran, CEO and chairman at Sigma Designs. "The addition of Wi-Fi to our G.hn, HomePNA and HomePlug AV solutions, allows us to offer operator flexibility whether wireless or wireline networking is required."

Quantenna has developed its 4x4 MIMO technology to meet the stringent requirements of highly reliable media-based applications like IPTV and whole-home video distribution. Quantenna's family of Full-11n(TM) chipsets uses the company's cost-optimized, third-generation QHS710 chipset to deliver up to 600 Mbps of bandwidth.

"Our partnership with Sigma is another significant step to accelerate the adoption of our industry leading MIMO technology for whole-home multimedia entertainment," says Dr. Sam Heidari, chief executive officer for Quantenna. "This new reference design with Sigma demonstrates how two industry leaders can bring unparalleled performance and value to OEM partners and service providers for next generation set-top box designs."

The award-winning SMP8652 media processor from Sigma Designs integrates a complete suite of next-generation capabilities for a single-chip SoC solution with powerful multimedia processing, robust content security system, multiple on-chip CPUs, and a full complement of system peripherals. Its combination of on-chip processors and memory controllers provides the needed headroom for the next generation of client middleware and software stacks. At the same time, establishing a minimal memory footprint using a high-speed 32-bit data path enables implementations with small form factors, lower bill of material (BOM) costs, and lower power dissipation.

Availability The reference design will be available in the first quarter of 2012 for early access customers. Sigma Designs will be demonstrating, by appointment only, the Quantenna-based reference design at the 2012 Consumer Electronics Show in Las Vegas, N.V. (January 10th - 13th), at the Las Vegas Hilton.


Finding MIMO: HomeGrid Forum Endorses Draft ITU-T MIMO Specification for Extending G.hn

During the latest ITU-T Study Group 15 plenary, the G.hn work group saw the culmination of months of study with agreement on a draft new standard (ITU-T G.9963) called G.hn-mimo that adds state-of-the-art MIMO (Multiple Input Multiple Output) technology to the G.hn standard for high-speed networking over existing home wiring.

The HomeGrid Forum fully supports this new standard, stating that the addition of MIMO will significantly increase robustness, rate, and coverage, making G.hn by far the premier home networking technology, especially in very challenging noise environments such as powerlines in the home.

The group of ITU-T experts that last year completed the development of the G.hn standard for networking over existing home wiring (i.e. powerlines, phone lines and coaxial cable) has been developing a new standard that adds MIMO to G.hn.

The specification is initially focusing on powerline as this is the most challenging wired medium.

MIMO works by using the multiple paths available because power wires have 3 conductors (phase, neutral and ground). G.hn-mimo standard devices will be able to send traffic streams over multiple paths simultaneously and thus increase throughput rates and noise robustness. In cases where a communication path is affected by impairments, other paths can be used to compensate and hence ensure full coverage and persistent delivery of content. ITU-T G.9963 is the first powerline MIMO specification to be developed by an international SDO (Standards Development Organization). As G.hn-mimo is an enhancement to G.hn, G.hn devices with MIMO are fully interoperable with devices built to the G.hn standard approved in 2010.

The technical work on G.hn-mimo is due for completion by July 2011, with Consent (official ITU-T Recommendation status) expected in Fall 2011.

"Service Providers and equipment vendors that are planning to start G.hn deployments this year need to have a clear view of the G.hn road map and which enhancements are coming," said Matt Theall, President of HomeGrid Forum. "G.hn is already the best standards-based solution for any wired home networking application, and the G.hn-mimo enhancements will ensure that G.hn will continue to be the best for years to come."

Sigma Designs First to Market - Powerline Communications with MIMO Technology

June 13, 2010 1:06 AM in MIMO  | 0 comments  | 0 TrackBack

Yesterday, while being focused on the approval of the G.hn standard announcement by HomeGrid Forum, I also learned that Sigma Designs (Nasdaq: SIGM), who is one the silicon vendors involved in yesterday’s HomeGrid announcement, had a pretty interesting bit of news in their own right.

Screen shot 2010-06-12 at 8.04.52 PMThey took the lead on being the first silicon vendor to announce MIMO (multiple input, multiple output) features over power line communications chipsets.  Having MIMO functionality, it will deliver up to twice the performance of existing power line solutions when used in conjunction with G.hn.

Why This Matters

MIMO delivers a substantial improvement in power line performance because it utilizes all three wires in a power outlet: the phase, the neutral and the ground.

When you use all three wires, rather than just two, it means multiple inputs and outputs can be created. This is going to open up more channels of communications across homes like mine- and millions around the world, particularly in countries where powerline is more prevalent.  This means that we’re going to get higher guaranteed throughput, increased robustness, better immunity to noise, and improved coverage across outlets.

It also means that that consumers, knowing that his new technology comes from brands using Sigma Design's technologies will work much better with surge protectors and across multiple phases - the leading inhibitors to mass deployment of power line today.

Insights from Industry Analyst, Gary Schultz, CEO - Multimedia Research Group - By Using MIMO, Sigma will be able to deliver multiple HD video streams to over 99% of the power outlets worldwide.

"Installation complexity and cost are among the biggest impediments to IPTV deployment success," said Gary Schultz, Chief Executive Officer of Multimedia Research Group. "This new announcement by Sigma could simplify the installation process and change the cost structure for deploying IPTV. As a result, the industry could grow even faster than the 30% we are predicting." MRG expects the IPTV market to grow to 83 million households by 2013.

"This is potentially a real breakthrough," said Schultz. "It could change the industry landscape by making G.hn powerline communication a standard networking technology embedded into consumer electronics devices, gateways and set top boxes."

Read. Set. Ship.

Early MIMO functionality will first deploy in the Sigma CG2110 HomePlug AV solution starting next month, and will ship in more advanced versions that will double performance in Sigma's new G.hn solution expected later this year.
