G.hn is expected to be officially commercialized this year. After the global G.hn chip manufacturers began mass production in February 2013, Netcom equipment will also debut one by one. Among them, G.hn bridges will first appear in the retail market, and global telecommunications companies will introduce G.hn Netcom products in the second half of 2013.
The wired home networking technology G.hn has made a significant breakthrough in its recent development. At present, the Marvell G.hn chip has passed the certification of the HomeGrid Forum, and the other two important chip manufacturers Sigma Designs and Yichuan have also entered the final stage of certification, plus the first G.hn system. The System Plugfest was also completed in mid-December 2012, all adding new momentum to the commercial development of G.hn.
Entering the system test stage, G.hn makes great strides in commercial use
Tom Starr, convener of Study Group 15 working group of the International Telecommunication Union (ITU-T) and president of the Broadband Forum, said that the G.hn system-level interoperability test plan was jointly planned by the International Telecommunication Union and the Global Broadband Forum. Holding a system-level product insertion and removal conference can ensure that all G.hn products are compatible and interoperable, thereby eliminating the doubts of telecommunications operators and end users about G.hn-related products.
It is understood that the first G.hn system-level product insertion and removal conference was held in Hull, UK, and was held at the TRaC product certification laboratory recognized by the HomeGrid Forum. All G.hn system manufacturers can participate, including Netcom original equipment. Manufacturers (OEM), original design manufacturers (ODM) and home appliance brand factories, etc. After the product interoperability test was completed, many HomeGrid Forum member manufacturers followed the latest G.hn products at the International Consumer Electronics Show (CES) in January 2013.
IMS Research analyst Liam Quirke estimates that by 2016, global G.hn chip shipments will exceed 25 million, which is expected to create huge business opportunities for chipmakers.
Chips topped the G.hn market in February this year
Leading other G.hn chip manufacturers, Content Chip has not only taken the lead in obtaining the HomeGrid Forum certification, but also began to supply a small amount in February 2013, and can accept orders from Netcom's foundry, becoming the world's first mass production G.hn. The manufacturer of the chip.
Yang Naihua, senior marketing manager of Content, said that Content has started the development of G.hn chips since it acquired DS2 in August 2010. It is the earliest chip maker, so it has leading advantages regardless of technology and market development. The G.hn chip of the company has passed the certification of the HomeGrid Forum in terms of basic hardware and software integration, thus providing an additional layer of protection for the quality and stability of the chip.
It is understood that the content G.hn chip can support power line (Coaxial) and telephone line (Phone Line) transmission, and compared to other G.hn chip vendors only support 2? 50MHz frequency band, The chip can be expanded to support 2? 100MHz. In addition, the solution also has multiple input / multiple output (MIMO) functions and TR-069 remote management and maintenance technology, which can help telecom operators to effectively monitor remote power line products.
It is worth mentioning that the content G.hn chip first entered the stage of the International Consumer Electronics Show in 2013 (Figure 1); at CES, Netcom foundries such as Kangquan and Datron of Taiwan, mainland China ZTE, Tongwei Electronics, Cambridge Industries, and Asoka in the United States all use contented G.hn chips for demonstration functions of high-quality output of terminal products such as set-top boxes (STBs).

In addition to the above ODM and OEM customers, Taiwan ’s Yaxu, Kangshu and Pegatron, as well as European Teleconnect and Woxtex, have also adopted the satisfactory G.hn program. At this stage, there are a total of six Taiwanese, eight Chinese mainland, and European, American and other customers, G.hn chip manufacturers currently have the most customer base.
Yang Naihua further pointed out that because European telecommunications providers mainly rely on system integrators to supply Netcom products, and there are fewer Netcom OEMs in Europe, system integrators purchase G.hn equipment in Taiwan, mainland China, etc. The Netcom factories in these two districts are equivalent to opening up channels to the global market.
On the other hand, from the perspective of the current development of the G.hn market, it is now in full swing into the stage of interoperability testing between chipmakers and Netcom factories. Yang Naihua analyzed that after the completion of the system-level testing phase, the time for telecom operators to import G.hn Netcom products is about the second half of 2013; after the telecom operators adopt them in large numbers, G.hn home appliances can be expected to be listed one after another.
In fact, the telecom operators that have stated that they will adopt G.hn technology include AT & T, Telefonica, Singapore Telecom, China Telecom and Chunghwa Telecom. Yang Naihua predicts that due to the long history of using powerline networks in Europe, it is expected to be the first region to deploy G.hn technology, while mainland China, which has not yet deployed wired home networking technology, has the opportunity to become the second wave of G.hn. hn network area.
It is worth noting that Yi Chuan, one of the three largest G.hn chip vendors in the world and the only G.hn chip vendor in Taiwan, also demonstrated the G.hn chip solution at the 2013 International Consumer Electronics Show Demo (Discrete MulTItone, DMT) and Analog Front End (AFE) chip demonstrations prove the company's technical strength and market determination.
Notes about G.hn
G.hn is derived from the English "Home Network" (Home Network), and "G" means "transmission system and media, digital system and network" developed by ITU-T Type of technical standard series family. Among the G series standards, there are other well-known standards, including G.992.1 (ADSL), G.992.5 (ADSL2 +), G.993.2 (VDSL2), and common audio codecs, such as G.711 and G.729, etc.
The original intention of G.hn's design is to solve the problems of the existing wired networking technology, including: Under a single PHY / DLL, enjoy multiple line connections: G.hn defines a general PHY (Physical Layer, physical layer) and DLL (Data Link Layer) architecture can operate in any home networking including power lines, telephone lines and coaxial cables. With G.hn, it is no longer difficult to design a single chip that can operate on the line, because all the main parameters (modulation mode, error correction, encryption, media access control, etc.) can be used for different In physical media.
