- Mainland China & Taiwan ‘Harmonize’ on G.hn as Their Wireline Home Network Technology
– Chinese Backers Include China Telecom, China Mobile, Huawei, ZTE and Xingtera
Mainland China and Taiwan have “harmonized on G.hn as their ‘smart home’ wireline home network technology,” according to the HomeGrid Forum. It said Taiwan’s Institute for Information Industry (III) played a leading role in the effort.
The announcement must be a shock to backers of HomePlug and MoCA, which until now have had 100% of the wireline home networking market — not including wireline Ethernet that dominates in offices rather than homes.
The significance of the announcement cannot be downplayed.
For years detractors have pooh-poohed G.hn, including whether it’s even needed and whether its developers could ever get it to work and get it to market at competitive prices.
The announcement will re-energize makers of G.hn chips and boxes and re-invigorate them in their efforts to get the world’s telcos on board the G.hn train. The Chinese goliaths backing G.hn include the countries two dominant telcos China Telecom and China Mobile, its two largest telecom equipment makers Huawei and ZTE plus the chipmaker Xingtera.
China is in the midst of a multi-billion dollar government-mandated effort to deploy the world’s most modern broadband and home networks. If the two Chinese telcos follow through and deploy G.hn-based networking throughout their footprints, it will make China the world’s largest market of home networking gear and chips.
The G.hn technology does what MoCA and HomePlug do separately: it operates over both powerline and coaxial cable. It’s also been designed to operate over the existing copper telephone wires that are in most residences although at much slower speeds.
HomeGrid said mainland China’s Ministry of Industry and Information Technology and Taiwan’s SINOCON Industrial Standards Foundation have been meeting for years about harmonizing technology under the banner of the “Cross-Strait Forum on Information Industry and Technology Standards.” See: http://www.sinocon.org.tw/achievement/?G=1&K=12)
Their most recent decision is that G.hn is to be the standard for wireline home networks for both mainland China and Taiwan.
The move towards technology harmonization by mainland China and the independent republic of Taiwan, which China still claims, has greater political implications than can be reported on here.
At the most recent meeting, Taiwan’s III led a delegation of executives of Taiwanese companies involved in smart home devices, home networks and their components:
Allion Test Labs VP Lai Junheng
Metanoia Communications president Wu Jiande
III director general Dr Ko Hsien-Tang
Executives from the much better-known China-based companies that attended are:
There’s another twist to the Chinese broadband/home networking market as a result of China having millions of MDUs and few standalone houses. Typically broadband is installed to the basement or outside the MDU. Then another wireline technology is used from there to each residence, which we called BAN for building-area-network. A separate in-residence home network that connects to the BAN usually includes Wi-Fi for mobile devices and a wireline network for pay TV. Wi-Fi that’s used in MDUs is said to be hampered in its performance by the many other nearby Wi-Fi routers.
So, if G.hn has won the in-residence race, there’s still an opening for other wireline technologies in the broadband-to-residence (BAN) market…
