LONDON Broadband over powerline chip specialist SiConnet (Swindon, England) has merged its submission for the forthcoming IEEE P1901 powerline communication coexistence standard with the proposal submitted jointly by the Consumer Electronics Powerline Communication Alliance (CEPCA) and the Universal Powerline Association (UPA).
The move comes ahead of a meeting of the P1901 Powerline Working Group, taking place next week in Boston, U.S.
It was not completely unexpected. Earlier this year , Russell Haggar, SiConnect's VP for marketing, told EE Times Europe after the company's proposal specifically focused on the Quality of Service (QoS) aspect of the coexistence standardization effort was accepted as one of the four to move forward to more technical work, that the groups would work to coordinate efforts.
"Our Quality of Service (QoS) 'partial' proposal was well received, and we will now have discussions with some of the other groups whose proposals will also advance to integrate the work into one ahead of the next P1901 meeting", Haggar said after the last P1901 working group meeting in Edinburgh.
The other proposals in the coexistence stream came from a combination of the Consumer Electronics Powerline Communication Alliance (CEPCA) and the Universal Powerline Association (UPA); the Home Plug Powerline Alliance; and from Telcordia.
The merger means that the number of proposals being considered for powerline coexistence has now been reduced to just two, and the Boston meeting is expected to choose between one of these alternatives for progression towards ratification as the IEEE powerline co-existence standard.
"The engineers from all three groups have worked very hard at combining their ideas to create this proposal and we all hope that this new joint proposal will be adopted at the forthcoming P1901 meeting. For true coexistence to be achieved between differing powerline applications, an effective QoS strategy is needed to accommodate all prospective classifications of traffic, be they audio, video or data oriented. Itís an essential component," said Haggar.
SiConnect says a key advantage of its proposal is that it enables low-cost powerline technologies to participate in the emerging standard without affecting their cost of implementation. This means that powerline connectivity can cost-effectively be incorporated into mass market consumer appliances, opening up much wider markets for powerline technologies.
