Family's network of the new standard spark is argued
A group of powerline technological supporters are suggesting establishing the family which forms the arch and networking the standard.
Those International Telecommunications Union those works G.hn standard purpose to create several prove, include powerline singly, coax and the telephone wire net price. It uses and will not enter into an alliance with HomePlug Powerline use, says HomePlug the president robs a code of technology that the blue technology of gram will be mutually operated together. Members have already used HomePlug technology to ship up to 27 million, the group claims.
” It can say we say the opposition G.hn while being too strong, ” Blue gram is said. ” We are afraid performance or level that can even reach our HomePlug AV standard is best, it is not a good thing of a market that another technology will contravene HomePlug in many aspects, ” He adds.
The core of the question is as G.hn suggests the low odd-even check-up of density (LDPC) When,it lasts turbine to be the straight in the codes to HomePlug to correcting error. Incompatible in two times and support technology to make HomePlug one big and expensive, blue gram will be said.
In addition, it is impossible for LDPC not to offer quite more performance than turbine code and it approves for to be may difficult, blue gram increases. ” A lot of people will say if you can have received more performance since LDPC, and some says you can be argued to receive more performance from the turbine code, ” He says.
HomePlug group set about making AV and may be passed 2.0 standards that will be finished at the beginning of next year, appoint to employ 600 Mbit/s of layer at most and in the flow of a Gbit/s of PHY. Though group whether one layer of flow of application above the noisy cable say first accurate goal clearly, but G.hn spec directs against Gbit/s PHY.
Interoperability question
If the standard of International Telecommunications Union adopts the turbine code, group HomePlug may support G.hn, blue gram is said.
Exceed 3 months after International Telecommunications Union finishing sets about making PHY of G.hn spec at the end of last year, criticism comes, begin to prepare from ASICs for the work. The group expects that the media about it will enter and control personnel’s building to finish the work in September to cherish a hope shipping products in 2010.
Last month, other local networks group 3 signalled their will through installation (operate and use HomeGrid relation of forums) Cooperate with International Telecommunications Union spec, a special industrial group promotes G.hn. 3 groups include Powerline communication alliance, HomePNA alliance and general civil electronics industry of Powerline association.
Blue gram lift he criticize for with with Matt Theall, a Intel carries out with HomeGrid group that leads of head of former group HomePlug.
Exchange in an E-mail, Theall says he will not discuss and comment on to concrete technology the group of International Telecommunications Union. However, the work in the group really have on the basis of interoperabilities that he really says.
” HomeGrid believes the coexistence of using other technology is requirements for G.hn, and a mechanism of coexisting is being adopted and reached this goal in G.hn, ” He writes. ” From 2006, it is a technology of future generation that G.hn has already been used in, and HomeGrid believes G.hn is expected to deliver to future generation performance, ” Theall increases.
At the end of last year, it was interested in finishing 12 that various powerline make the deadlock crossed a IEEE powerline standard. IEEE 1901 proves that basically wish the competition powerline to be close to including HomePlug and G.hn, and create the mechanism of coexisting, so they do not interfere with each other.
