HomePlug Powerline Alliance

IEEE 1901 Specification Succeeds in First Sponsor Ballot, Ratification in September

2010-04-15T17:15:00.000-07:00

Last Friday (April 9, 2010), the results for the first sponsor ballot of the IEEE 1901 Draft Standard came in with over 80% of voting entities approving. This sets the stage for ratification in the Fall of the first global powerline networking standard by a major Standards Development Organization (SDO).

With 1901 joining other highly successful IEEE networking standards (such as 802.3 for Ethernet and 802.11 for WLAN), powerline networking enters a new phase of performance and possibilities. Now, retail vendors, service providers and Smart Grid companies can move powerline product development rapidly forward resting on the firm foundation of a global standard that ensures product interoperability and with the added benefit of full backwards compatibility with the millions of HomePlug AV-based products already in the market today.

This is likely the most significant step in the history of the powerline industry to date and will, no doubt, spur worldwide adoption of this technology.

It is noteworthy that no other standard as complicated as 1901 has ever passed this IEEE milestone (>75 percent acceptance) in a first pass sponsor ballot. This is strong evidence of the maturity of the technology and the very widespread support within the industry.

This extraordinary outcome is due in great part to the very thorough and significant effort put forth by the Working Group and involved member companies. To begin, they performed the hard and tedious work to develop the market requirements for access, in-home and smart energy portions of the standard. Many stakeholders – utilities, service providers, OEMs/ODMs and silicon manufacturers – provided invaluable input and worked tirelessly to improve the underlying technology throughout the process.

Following the requirements process, detailed technical proposals from all the key technology providers were gathered and carefully reviewed and analyzed, including performing simulations and field testing. New inventions were made along the way, some of which were significant breakthroughs for the powerline industry that were later adopted by other SDOs.

Each technical proposal was evaluated by the group, and underwent thorough technical scrutiny, technical evaluations, and simulations. Decisions were based on technical superiority and relevance to market requirements. More than 3000 comments were received during the letter ballot process, and each and every one of them was addressed by the group to improve the specifications.

During the sponsor ballot process, more comments have been received. Many of these represent opportunities to further improve the current specification. The plan is to get the document ready to be sent to REVCOM in August. If this timetable is met, it will be an unprecedented event in terms of the speed with which such a group has readied a specification of this scope and complexity.

It’s hard to overestimate the importance of the 1901 standard for powerline networking, and the hard work and dedication of the many companies and individuals who’ve worked so hard for this well-earned milestone.

Congratulations to all!

HomePlug Powerline Technology Proves its IPTV Mettle

2010-03-25T21:00:00.000-07:00

The 2010 IPTV World Forum in London offers a proving ground for the technologies that help solve this problem: "How do I get a broadband signal to my television?"

A lot of people have been asking this question -- especially business analysts.

Parks Associates has uncovered that 36% more US households are connecting PCs to TVs with more than 75% using that connection to watch online videos
iSuppli notes that Internet-enabled TVs (IETVs) are the fastest-growing approach to access the web on a television
InStat conducted research pointing to over one-half billion web-enabled consumer electronic devices in operation by 2013

The difficulties with using wireless technologies for streaming media has been well documented, but HomePlug technology, with its reliable and robust "hard-wired" approach and no need to install new wiring, provides a perfect solution for IPTV and other web-based services.

In his letter to the delegates at IPTV World Forum 2010, HomePlug president Rob Ranck noted, "With dozens of service providers already deploying HomePlug powerline networking products, HomePlug has truly become a proven choice for IPTV home networking."

HomePlug member companies exhibiting at IPTV World Forum included Atheros, Devolo AG, LEA, and Sigma Designs, Inc.

Ranck concluded, "This underscores the reality of HomePlug powerline technology – it’s all about having multiple vendors competing in the market with interoperable products. This benefits both service providers and end-customers."

CeBIT 2010: HomePlug Continues its Market Leadership

2010-03-16T14:20:00.000-07:00

The fairgrounds at the Deutsche Messe in Hannover, Germany are quieter now, but the buzz about the HomePlug Pavilion at CeBIT 2010 is still on the lips of those who made the trip.

It's fitting that Europe, the largest market for HomePlug-certified products, was also hosting one of the largest displays the HomePlug alliance has ever built -- a clear indication of the growing business of powerline communications and HomePlug's dominance of the market.

It was at CeBIT 2010 that breaking news began to circulate that IEEE 1901, the global powerline standard that is interoperable with HomePlug AV technology, was on its way to a Sponsor Ballot, the final stage in the IEEE's process for establishing a standard.

With the HomePlug alliance celebrating its 10th anniversary in April 2010, it's amazing to map the progress of a technology that many believed was an impossible dream just ten years ago. Some say if powerline communications technology were perfected earlier, that many other wired technologies simply wouldn't be needed. With physical data rates nearly doubling with each revision, HomePlug powerline technology is now mentioned in the same breath as WiFi and Ethernet.

At CeBIT 2010, the HomePlug alliance built an impressively sized pavilion and invited their members to participate. A prominent location in Hall 13 of the mile-square Duetsche Messe campus spawned a planning process taking nearly a year. By the time the doors to CeBIT opened, the HomePlug Pavilion reflected its market position; it was an imposing presence replete with meeting rooms, sitting areas, a place for press and media to view presentations and take interviews -- even the "HomePlug Bar" to entertain visitors.

In another example of the value that HomePlug products offer service providers, T-Home, the division of Deutshe Telekom focused on Broadband and Fixed Networks, introduced its first HomePlug AV products called Speedport Powerline 100. Over 30 service providers globally use HomePlug products in their rollout of IPTV, whole-house internet sharing, and a host of other services.

Displaying the latest solutions and the newest HomePlug-certified products to hit store shelves were HomePlug member companies Atheros, GigaFast, Gigle Networks, LEA, and SPiDCOM Technologies. devolo AG -- the world's market-leading manufacturer of HomePlug products, rounded out the pavilion with a display of their best-selling HomePlug dLAN products for both residential and business use.

Among the news that always accompanies an event of CeBIT's magnitude were announcements and demonstrations of new ultra high-speed products from Netgear and devolo AG. The new adapters are interoperable with both HomePlug AV technology, and the upcoming IEEE P1901 standard.

Germany's devolo AG also introduced adapters that provide a simple way to combine wireless and powerline networks, solutions for directly connecting USB devices, and the first set-top box for digital satellite television that uses the power lines to connect between the satellite antenna and the set-top box.

With all the various applications of HomePlug technology shown at CeBIT, the news that HomePlug AV technology is destined to become a worldwide standard through the IEEE, and the wide variety of companies and products that support HomePlug technology, it's no wonder that the technology world is continuing to line up behind HomePlug!

IEEE 1901 Specification Moves to Sponsor Ballot!!!

In Santa Monica, few weeks back, the IEEE P1901 group took a critical step towards publication of the final specifications. The group resolved all the comments that were submitted, and approved the specifications for sponsor ballot. More than 95% of the group agreed to initiate the sponsor ballot process, reflecting the groups’ confidence in the maturity and completeness of the specification. Click here to see the press release from IEEE.

The IEEE P1901 group is driven by its members. Using a formal open process that ensures the specification considers the input of each and every member participating in the group, the group ensures the specifications developed incorporate the expertise of all members who understand and appreciate the market and the technology, while also providing them with ownership of the specification. This process guarantees the success of the final specification.

The IEEE P1901 members reflect the unparalleled diversity of powerline communications technology itself -- including smart grid players, silicon manufacturers, service providers, ODMs, OEMs, CE manufacturers, in-home technology players, access technology players, and transportation technology players. Progressing the specification towards sponsor ballot, and receiving approval from all these varied stakeholders, speaks volumes about the quality of the specifications.

IEEE 1901 technology is already in the marketplace. At CES 2010, Atheros announced chipsets based on IEEE 1901. IEEE 1901 chipsets have also been announced by Gigle Networks, Arkados, and STMicroelectronics.

Manufacturers like devolo, Netgear, Belkin, and Monster already have products planned based on IEEE 1901 technology.

It's clear the PLC industry is converging around IEEE 1901 technology...

4 silicon manufacturers have already announced chipsets
4 ODMs already have products based on IEEE 1901

This is just the beginning and more good news is to follow.

Thanks

HomePlug Shines at CES 2010

Walking into the exhibit halls at the Las Vegas Convention Center, no one could miss the HomePlug TechZone at CES 2010. At over 20-feet tall and barely squeezing into one thousand square feet of floor space, it dominated the portal to the South Hall and was chock full of new HomePlug-certified products from more companies than you can shake an extension cord at.

Sponsored by six HomePlug product companies Asoka, GigaFast, Plaster Networks, Russound, Tatung, and six HomePlug semiconductor providers Arkados, Atheros, Coppergate (a Sigma Designs Company), Gigle Networks, SPiDCOM, and STMicroelectronics, the TechZone demonstrations included HDTV distribution, whole-house audio systems, WiFi extensions, videogame connectivity, surveillance, in-home displays, smart meters and smart grid solutions – even some that combined Zigbee and HomePlug Smart Energy technologies (courtesy of JetLun).

The clear market leader in powerline communications (as of January, over 40 million HomePlug products have been sold), products containing HomePlug technology from brand names such as Aztech, Belkin, Checkolite, devolo AG, Linksys by Cisco, Monster Cable, NetGear, Sling Media, Solwise, and Zyxel filled six tall display cases that framed the pavilion.

Besides a giant display, the HomePlug alliance also made some giant announcements:

The IEEE 1901 Draft Standard for Powerline Communications was published by the Institute of Electrical and Electronics Engineers (the same folks who brought you the wireless 802.11 standards). Historically, IEEE’s open standards dramatically boost the adoption rate of new technologies.
HomePlug’s new liaison agreement with the Multimedia over Coax Alliance (MoCA) paves the way to help service providers feel comfortable that reliable high-speed wired connectivity is available via any wire in the home.
Continuing with theSmart Energy focus, the HomePlug alliance announced that the HomePlug GP (“Green PHY”) Specification for Smart Grid Applications will be available for implementation in 1Q/2010. Fully interoperable with both HomePlug AV and HomePlug AV2 products, the HomePlug alliance expects to begin certifying chips and products in early 2011.

The alliance and its members expect to release more news at 2010 progresses. Watch this space and homeplug.org for updates.

Fun Times and Success Continues in IEEE 1901 Land....

Last week in Tel Aviv, IEEE 1901 accomplished an unprecedented feat. The accomplishment could be explained by nothing else but phenomenal, possible, because of the positive contributions and team spirit within the IEEE 1901 group.

IEEE 1901 had more than 3000 comments to be resolved in 4 months.
Many naysayers went in public and said it can’t be achieved. Some even gave the examples of other standards forum and mentioned that it would take alteast 3 years to resolve all those comments.

Well, the IEEE 901 group accepted it as a challenge and resolved all those comments in an unprecedented time period- 4 months.

Yes, the members worked hard, yes there were more than 20 hour calls a week, yes, there were some times, when we had to skip dinners and lunch, but we accomplished it all.

In Tel Aviv, the IEEE 1901 group also agreed with super-majority that all the comments were resolved to the satisfaction of the group.

This paves the path for final spec publication by middle of next year.

This goes again in the face of naysayers or people with other interests who have continuously tried to bring down the IEEE 1901 efforts. IEEE 1901 group has always emerged strongly and proved them wrong at every step.

Forgotten is the fact that IEEE 1901 in a year’s time frame has achieved that no other standards have been able to accomplish

In December of last year, IEEE 1901 baseline was confirmed and since then many positive things have been accomplished by the IEEE 1901 group
Letter Ballot
Support of Smart Grid Applications
Support of Lower Data rates Applications
Support of Transportation activities
Resolution of more than 3000 comments
Streamlining of specifications – removal of part that remained immature tied to other standards group.

The group decided in Tel Aviv to publish and allow sale of the IEEE 1901 Draft Specification V2.0 from IEEE website. The Draft Standard should be available for sale from January of next year. This is a very strong endorsement of the quality, robustness and maturity of the IEEE 1901 draft specifications.

As Aristotle has said:

We are what we repeatedly do. Excellence then is not an act, but a habit.

Well, for IEEE 1901 group it has become a habit to repeatedly deliver on excellence.

Service Providers are continuing to voice support of Homeplug technology as the long term solution for powerline home networking.

According to Carol Wilson of Light Reading, "G.hn, the home networking standard whose physical architecture was adopted by the International Telecommunication Union (ITU) earlier this month, is not getting rave reviews from some broadband service providers because of concern that the standard lacks backward compatibility with existing home network technologies, particularly HomePlugAV, the powerline home network".

The solution is simple. A planned Amendment to the G.hn PHY is currently under discussion in ITU. That Amendment must ensure compatibility with HomeplugAV.

Third Knock in Roughly Three Weeks for G.hn

There is a great article in SmartGridToday publication asking the question:
"Could MoCA/HomePlug win in-home networking wars?"

The author cites three significant events in last three weeks that have created positive impact to the home networking space in general.

1) Participants in smart grid Interoperability Standards questioned the viability of Ghn, though NIST included it in the draft roadmap.

Truth of the matter is G.hn, does not have MAC specifications. They have only approved PHY specification, for which there is already an amendment. An amendment to a specification is a document that addresses the missing elements, additional features for the particular specification. G.9960(PHY document) that got approved last month, already has an amendment in works. This reflects the maturity and the completeness of the document.
Currently, apart from PHY specifications* (amendment- not yet published), G.hn has nothing to offer the industry.

2) IEEE P1901 200 Mbps PLC interoperability standard dropped the placeholder for third PHY layer meant to support G.hn

The group gave an opportunity to G.hn group to provide access extensions for PHY/MAC for 9 months. In those nine moths, there were no contributions provided that would address the access extensions for G.hn. This reflected again the maturity of the G.hn specifications. Finally, to streamline the specifications, IEEE 1901 group overwhelmingly decided to remove G.hn compatible PHY from the specifications.

3) Entropic will partner with Intellon to boost the availability of home networking solutions combining coaxial cable and powerline Communications.

According to Smart Grid, Entropic's work with Intellon amounts to the third knock in roughly three weeks for G.hn.
Unlike G.hn solution, the joint work will develop solution that will be backwards compatible with tens of million chipsets deployed in the market.

Well, fun times in IEEE 1901 land....

As I mentioned in my previous blog, that IEEE 1901 is making siginificant strides towards completion of the specification and an important step towards it was the approval of the letter ballot in July. Since then the group has dedicated its time to resolving the comments.

As per the last weeks' IEEE 1901 Boston meeting, we have resolved more than 50% of the comments. Unlike other standards group(where the editor decides himself as to the resolution is consulted before the comments are disposed.

Also, last week, the IEEE 1901 group unanimously agreed to include Smart Energy and Transportation Platform in the PAR.

During the meeting in Boston, the working group also decided to stop the development of the ITU-T G.hn Compatible PHY/MAC Draft option. Related chapters and annexes were removed from the Draft, becausse of the immaturity of the G.hn specifications.

Looking at the group composition one can really appreciate the diversity of IEEE 1901 membership ranging from utilities, service providers, OEMs, ODMs, technology integrators, CE manufacturers, silicon manufacturers etc. The groups' membership has been increasing steadily over the course of time.

Things are moving forward in a positive way and we expect the specfications to be ready soon.

Thanks

In the arena of home networking research and analysis, Parks Associates are the acknowledged leaders, and Kurt Scherf is the doyen. When Kurt speaks, you listen. Recently, Kurt has been discussing wireline technologies with service providers and his conclusions are very interesting.

Concerns about ITU G.hn’s failure to build in compatibility with the dominant existing technologies on powerline and coax, Homeplug and MOCA respectively are now clearly being voiced.

According to an article published in the standard, 15 October 2009, recent conversations with European service providers have convinced Kurt that HomePlug has strong backing from that industry, which is the most important channel for wired home network gear today. "I do not think that the G.hn effort will fully succeed until they take into account HomePlug and build in some compatibility with it," Scherf said.

Title: Avoiding PLC Market Fragmentation – Part 1

There has been buzz about the G.hn technology recently. Players who do not have any powerline market presence or the ones that has failed miserably to establish themselves in the PLC Market have created the buzz. They want to create a specification that is incompatible with the existing technologies--- resetting the market, creating fragmentation and falsely believing that this gives them a competitive advantage.

In this blog, I will provide few points as to how G.hn affects the powerline market space:

1) G.hn risks fragmenting rather than unifying the wireline market
ITU-T is a well-respected international Standard Development Organization (SDO) for the telecommunication industry and has played an essential role in creating standards for that industry, but ITU-T has no history of creating successful specifications for applications outside of telecommunications applications. A successful wireline home-networking standard must have broad market support from all industry sectors, including consumer electronics, cable and satellite service providers, computer electronics and, with the rapidly increasing interest in powerline communications applications in smart grid and electric vehicle applications, the utility and automotive industries. Most of these industries have a long history of supporting standards promulgated by the IEEE. If G.hn is unable to produce a standard that is interoperable with the recently approved draft IEEE 1901 standard, it will likely fail to gain market acceptance or worse, create a standards and market battle between G.hn and 1901, which could last for years, potentially slowing market deployment for all wireline networking technologies while customers, service providers in particular, wait to see which standard the market chooses, or select another technologies such as wireless.

2) G.hn integrated circuits (ICs) are at least 2-3 years from being market ready
Developing ICs to a new standard takes a great deal of time – silicon design and production qualification, firmware development, compliance and interoperability testing, reference designs and customer support, etc. This typically takes 3~5 years for a completely new specification, particularly for one of the complexity of G.hn plus several years to develop test plans, correct specification ambiguities and errors, and reach multivendor interoperability. Thus HomePlug IC suppliers have an additional 3 years to mature their product lines and develop the market before the first market ready G.hn ICs are available. This head start enjoyed by HomePlug and IEEE 1901 may be difficult to overcome unless G.hn is interoperable with HomePlug AV.

3) HomePlug AV is a de facto powerline standard
HomePlug is enjoying significant success in the market with over 40 million ICs shipped and in use by approximately 50 service providers representing over 70% of total powerline networking sales today. There are already two silicon vendors shipping HomePlug AV IC’s today (Intellon and Gigle) with four additional silicon provides with announcements for HomePlug AV ICs in 2009 (Arkados, CopperGate, SPiDCOM, ST Micro) HomePlug has an established Compliance and Interoperability test and certification program for HomePlug AV that is already successfully assuring interoperability among vendors. A key goal of any standards organization is to create standards that enable multiple silicon vendors to deliver interoperable solutions that offer multiple product choices for service providers and other customers, and drive competition over price and technology innovation. This goal is being achieved with HomePlug AV for the powerline home networking market. It is also important to note that except for ISP (Inter-System Protocol) and a few optional features, the IEEE 1901 FFT PHY and MAC are identical to HomePlug AV. Thus, HomePlug’s compliance process for HomePlug AV will be extended for IEEE 1901.

In my next blog article, I will post some additional points regarding how to avoid the fragmentation of PLC market.

HomePlug Technology Rocks!!!

NIST, mandated by Congress in the Energy Independence and Security Act (EISA) of 2007 to coordinate the development of a framework of protocols and model standards to achieve interoperability of the Smart Grid published the initial set of standards and specifications for inclusion in Release 1.0 of the Smart Grid Interoperability Standards Framework in May 2009.

The set of 16 NIST-recognized interoperability standards — ranging from smart customer meters to distributed power generation components to cyber security — included HomePlug technology.

The second release of the Interoperability Roadmap published in June 2009, explicitly lists HomePlug AV (HPAV), HomePlug Green PHY (HPGP) and IEEE 1901 as the NIST approved technologies.

Thus, HPAV/HPGP/P1901 are the only broadband PLC technologies included in the Interim Roadmap.

A broad range of stakeholders were engaged in the development of this Interim Roadmap. Over 1000 stakeholders participated in workshops to achieve consensus on the critical standards and standards development activities needed for the Smart grid.

Inclusion of HPAV, HPGP and IEEE 1901( interoperable with HPAV) in the smart energy roadmap goes onto prove the superiority and the market confidence HomePlug Technology enjoys.

A set of standards for the devices that connect the grid is critical to the progress of the smart grid, and to meet President Obama’s plan for a smart electrical grid to lower energy costs for consumers and reduce greenhouse gas (GHG) emissions, according to the U.S. commerce secretary Gary Locke and U.S. energy secretary Steven Chu. These standards will allow users to connect directly with their power suppliers using real-time, two-way communications technologies.

Importance of Interoperability

In my last blog, I talked about the IEEE 1901 Draft Standard that was approved in Tokyo and its interoperability with HPAV. In this blog, I would like to demonstrate with use case, the real significance of Interoperability for all the stakeholders.

Use Cases:

a. Pierre lives in an apartment in Paris, France. Most of his neighbors, including Jean who is Pierre’s best friend, already have HomePlug adaptors; HomePlug embedded STBs for IPTV delivery applications and video distribution. Pierre buys a non-HomePlug/non-IEEE 1901 solution along with his Plasma TV set for IPTV applications. He tries to connect the adaptors in his apartment. Since the adaptors he bought were not HomePlug/IEEE 1901 interoperable, he started having problems receiving clear picture on his TV set, because of interference. The picture is grainy and the sound quality is horrible. He tries fiddling with his TV set and changing the connection outlets but with no success. He concludes that the problem is with the TV set and he returns the TV set back to the store. This is a significant loss for the store from which he bought and to the brand of the TV, he purchased, as studies have showed that if the first experience is bad with a particular brand or the store the user refrains from buying the same brand or from the store in the future.

The above use case demonstrates the importance of interoperability for the user as well as the players in the value chain (TV manufacturers, Electronic Stores). Having an interoperable solution would prevent the above scenario. IEEE 1901 interoperable/HomePlug AV interoperable solution would yield in the best experience for Pierre as well as the value chain players. Another interesting fact to realize is HomePlug is an already established technology and thus introducing a non-interoperable solution would cause tremendous problems to the non-interoperable solution.

b. Jean, who is Pierre’s best friend, has IPTV service from “PT”. “PT” is the largest seller of HomePlug Devices and the biggest HomePlug proponent in France because of the ease of installation and the near zero return rate for HomePlug devices. When Pierre plugs in his non-HomePlug/non-IEEE interoperable solution in the socket, it causes interference in Jean’s network. Unaware of what Pierre was doing, Jean calls PT complaining about the problem. Jean mentions that he has been using the PT service for more than 5 years and he has never experienced any problem before. PT checks the network from its side and everything looks clear to them, except for added interference. Not knowing where the added interference is coming from PT sends the technicians to check for it. By that time, Pierre was frustrated and he had removed his non-P1901/non-IEEE interoperable solution out of the outlets. Thus, the line had become clear and the technicians could not find the problem. Jean had good service now. Pierre’s effort to use non-HPAV/ non-IEEE 1901 interoperable solution caused PT to send their technicians to the field handle the phone calls, address the customer’s woes- all resulting in added expenses for PT.

The above use case demonstrates the importance of interoperability for the existing customers and his service provider. The above use case is realistic as it would be hard to control users buying the adaptors from the retail market. This would cost significant amount of time and money for the Service Providers, grievance to the customers for no obvious fault of theirs. This will result in very bad reputation for the non-HPAV/non-IEEE 1901 interoperable solution.

HomePlug currently has sold more than 35 million chipsets and is on course to selling more than 200 million chipsets by 2013 [Source: iSuppli Wired Communications Q4’08 Topical Report].
If a non-HPAV / non-IEEE 1901 interoperable solution enters the market it not only results in degraded performance but also causes interference to the deployed HomePlug chipsets.

Thus, “interoperability” is not a “good-to-have” requirement, but a “MUST” requirement for success of power line technologies and for that matter the home networking technologies. IEEE 1901 has realized this market reality.

IEEE 1901 Momentum Update

IEEE 1901 is continuing to capture the minds by making good progress. The standard development process is moving forward at a brisk pace given the complexity of the technology. I was at the IEEE 1901 meeting in Tokyo last week and the work was focused on getting the specifications delivered for letter ballot (IEEE 1901 Draft Standard). I was very pleased to see the amount of co-operation among major contributors in the group. The work was a concerted effort by most of the industry players.

If you are not following IEEE P1901’s history, it delivered on its promise to send the baseline text for letter ballot (IEEE 1901 Draft Standard) by July.
This implies that the specifications were stable and mature enough for designers to start their design. This is a significant milestone in IEEE standards development process.

In order to be compliant with the new standard HomePlug chipsets need to add only ISP/IPP element, HomePlug AV devices are already interoperable with future IEEE 1901 devices. The PHY/MAC of the IEEE 1901 standard is already implemented in silicon and field tested. The document defines ALL the details of MAC and PHY and for the parties interested in understanding the details, I can say that the agreed upon standard has more than 1500 pages that provides all the intricacies and the details for implementation.

The striking feature of the approval process was that the letter ballot was approved with more than 82% of the votes. The prospects look good for sponsor ballot in December 2009 and the standards publications in 1H2010.

HomePlug AV – The Only High-speed Power line Technology with multiple silicon providers

It is expected that HomePlug AV technology will have 6 silicon providers by the end of the 2009. It’s the only 200Mbps powerline technology with multiple silicon providers.

Here are links to announcements from all the companies:

Intellon: http://www.intellon.com/company/press/pressrelease.php?ReleaseID=208

Gigle: http://www.gigle.biz/images/Press_Homeplug_Certification.pdf

Arkados: http://arkados.com/Press-Releases/2008-10-30-STMicro-Arkados-Agreement.pdf

CopperGate: http://copper-gate.com/solutions/homeplug_av/

SPiDCOM: http://www.spidcom.com/cms/site/PDF/Press-Releases/20090223_SPC300-HomePlugAV-SoC_PR.pdf

STMicroelectronics: http://www.st.com/stonline/stappl/cms/press/news/year2008/t2339.htm

Having multiple silicon providers cements HomePlug’s position as the defacto powerline standards and provides its customers with competitive costs and complementary and diverse features.

Plus, the solution provided by Gigle has already been HomePlug certified and is interoperable with the existing deployed base.
