The International Telecommunications Union (ITU) and the Institute of Electrical and Electronics Engineers (IEEE) are accelerating the competition for home mixed network opportunities. In addition to the G.hn standard, the International Telecommunication Union is expected to publish the Open Protocol AbstracTIon Layer (OPAL) specification compatible with the IEEE 1905.1 standard in the fourth quarter of this year, and implement IEEE 1905.1 technical support in software. In order to prevent the G.hn forces from sitting on the 1905.1 working group, the working group has also stepped up the development of the new P1905.1a standard. It wants to first support the G.hn technical support features and enhance the willingness of manufacturers to adopt.
He Zhixiang, head of the Institute of Intelligent Netcom Systems, said that no matter whether wired or wireless networking technology is an important backbone to improve the overall smart home use situation, the major standards-setting organizations will certainly not let go of the huge business opportunities. The specifications are early in the card market, and the competition between the International Telecommunication Union and the IEEE is the most intense.
He Zhixiang further analyzed that the International Telecommunications Union led Marvell, which promoted the G.hn standard, which integrates Power Line, Coaxial Cable and telephone line cable transmission media; IEEE 1905.1 Working Group Qualcomm Atheros, Broadcom and other chip factories are the main members, and strive to achieve wireless area network (Wi-Fi), power line, Ethernet network and coaxial cable multimedia alliance (MoCA) specifications Interoperability.
This competition is undoubtedly a wrestling battle between chip vendors, telecom operators and system manufacturers. He Zhixiang pointed out that since the International Telecommunication Union is affiliated to the UN organization, its influence on various countries cannot be underestimated, and the alliance has planned to publish the OPAL standard in the fourth quarter of this year, and is committed to integrating data link layers using software technology (Data Link). Layer) and Network Layer, bridging various wired networking technologies under the G.hn standard and wired/wireless technologies under the IEEE 1905.1 standard to implement a new generation of heterogeneous network application scenarios.
It is understood that members of the IEEE 1905.1 working group will see the international telecommunications alliance's offensive, which will affect the future of the 1905.1 standard. It will hold a membership meeting in Orlando, Florida, from February 25th to 27th. Drawing on the development of the IEEE P1905.1a standard, the previous standards were revised, and support and improvement of the Media Access Control (MAC) layer and the physical (PHY) layer were added to introduce the next generation digital home network standard for heterogeneous technology.
He Zhixiang revealed that the focus of the IEEE P1905.1a standard will be compatibility with the G.hn standard, because the G.hn standard not only has a high penetration rate in Europe, but also Korean telecom operators SK Telecom, KT, LG U+ in recent years; China Telecom China Telecom; American telecommunications company AT&T, and even Taiwan's Chunghwa Telecom are all holding the G.hn standard, and are actively introducing related technologies into their services. Therefore, it is foreseeable that in the future, after the release of the OPAL standard, IEEE 1905.1 The living space will be greatly compressed, and chip makers such as Qualcomm Atheros and Broadcom cannot profit from collecting patent fees.
In fact, another major reason for the major telecom operators, chip vendors, and system manufacturers to bet on the G.hn standard is that the G.hn standard has Neighboring Domain Interference MiTIgaTIon (NDIM) technology, which can be used in multiple ultra-high UHD network television (IPTV) stream audio and video, to ensure that there is no electromagnetic interference between multiple power lines, the overall user experience is also greatly increased.
Whether the IEEE 1905.1 working group can consolidate the existing standards through the development of the IEEE P1905.1a standard will be the focus of this year's smart home networking market.
