IEEE P1901 Draft Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications

Report on the meeting held in Boston, MA, USA, 13-16 October 2009

At the meeting held in Boston, MA, the working group focused its efforts on comment resolution associated with the project's first letter ballot. Other activity included an important decision related to the ITU-T Compatible PHY/MAC and the creation of comments for submission into the process associated with the NIST Framework and Roadmap for Smart Grid Interoperability Standards.

The votes and comments on the group's first letter ballot answered the question of whether Draft Standard 1.0 is ready to go to Sponsor Ballot. Votes and comments were due by 14 September 2009. The vote received 61% affirmative votes and thus failed to receive the required 75% majority approval. More than 3,000 comments were received.

The Technical Sub Groups (TSGs) began resolving comments and updating the draft in September, immediately following the close of the vote. These efforts continued during the working group meeting and will continue via bi-weekly teleconferences after the Boston meeting until all comments are considered. By the last day of the working group meeting, 50% of the comments were addressed. TSG2 will hold a face-to-face meeting on 6-8 December 2009 in Tel Aviv, Israel, to further accelerate this work.

During the meeting in Boston, the working group decided to stop the development of the ITU-T Compatible PHY/MAC Draft option. Related chapters and annexes were removed from the Draft.

The working group also prepared comments in response to the request for public comment on the NIST Framework and Roadmap for Smart Grid Interoperability Standards.

A second letter ballot on Draft 2.0 is scheduled for December 2009 and Sponsor Ballot will follow.

The next Working Group meeting is scheduled for 8-10 December 2009 in Tel Aviv, Israel (see next meetings).

IEEE P1901 milestones

June 2005 - PAR approved
November 2005 - Adoption of the general work flow - Formation of a sub-group to develop unified requirements
January 2006 - Approval of the use cases - Decision to split the requirements into three clusters: In-Home, Access and Coexistence/Interoperability
March 2006 - Approval of the down selection process to achieve the baseline of the standard - Approval of the description of topologies.
September 2006 - Approval of the channel and noise models.
February 2007 - Approval of 400 requirements split into three clusters: access, in-home and coexistence - Calls for technical proposals
June 2007 - 12 proposals received; 4 proposals per cluster of requirements
July 2007 - 11 proposals passed the low hurdle vote; 4 in-home proposals, 4 access proposals and 3 coexistence proposals
September 2007 - Only two proposals per cluster remain for consideration after voluntary mergers.
October 2007 - One in-home proposal and one access proposal remain as candidates for confirmation after the first round of elimination voting.
March 2008 - A single coexistence proposal remains as candidate for confirmation after the last round of elimination voting.
July 2008 - The first round of confirmation voting for the in-home, access, and coexistence proposals is held. All three votes fail.
September 2008 - The second round of confirmation voting for the in-home, access, and coexistence proposals is held. The votes on the in-home and access proposals fail. The vote on the coexistence proposal is ruled invalid because the number of abstain votes exceeds the established percentage. A reset vote is held for in-home and access yielding a single proposal for confirmation in the in-home cluster, and two proposals for the access cluster. A voluntary merger in the access cluster is announced at the end of the meeting, bringing the total for access to a single proposal.
November 2008 - The first round of confirmation voting for the in-home and access proposals is held. Both votes fail.
December 2008 - The second round of confirmation voting for the in-home, access, and coexistence clusters is held. All three proposals are confirmed.
February 2009 - A tentative table of contents of the Draft Standard is adopted and four Technical Subgroups are formed to merge the confirmed proposals and develop a unified document.
July 2009 - The first Draft Standard is created. The Draft is sent for comment and vote on whether it is ready to go to Sponsor Ballot.
October 2009 - Development of the ITU-T Compatible PHY/MAC Draft option is stopped. Related chapters and annexes are removed from the Draft.

About IEEE P1901

The working group, formed in June 2005, has grown from 20 to more than 50 members. Members are corporations, government agencies, trade associations, universities, and standards developing organizations. Each entity has one vote.

About The IEEE-SA Corporate Standards Program

The IEEE-SA Corporate Standards Program allows entities to create standards within an ANSI-accredited, open process. Standards are developed in company-based working groups in which each member has one vote. This industry-oriented program allows for standards creation in as little as one to two years, depending on participant commitment and funding for IEEE services that can optimize all phases of the standards development process.
