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

Report on the meeting held in Las Vegas, NV, USA, in May 2009

The P1901 working group dedicated the majority of the Las Vegas meeting time to Technical Subgroup activity.

Technical Subgroup 2 (TSG2) (dedicated to MAC/PHY) presented to the working group thirteen revised chapters of the draft Standard on MAC/PHY layers and security. The Working Group approved with more than 83% majority.

TSG4 (dedicated to coexistence) presented a draft annex describing the Inter-System Protocol (ISP) that enables various BPL devices and systems to share communication resources (frequency/time) when installed in a network with common electrical wiring. In particular, ISP will allow P1901-compliant devices and ITU-T devices to coexist. The protocol provides configurable frequency division for Access and time division for in-home with a granularity compatible with the QoS requirements of the most demanding Audio/Video applications. The Working Group unanimously approved the ISP annex.

The TSGs will continue holding weekly teleconferences. In addition, TSG2 will hold a face-to-face meeting during the week of 15-19 June 2009 in Fukuoka, Japan.

The P1901 working group stated its interest in the IEEE P2030 Working Group that is slated to develop a Guide for "Smart Grid Interoperability of Energy Technology and Information Technology Operation with the Electric Power System (EPS) and End-Use Applications and Loads". Chair Faure of P1901 and various member entitiy representatives will participate in the P2030 kick-off meeting scheduled for 3-5 June in Santa Clara, CA, USA.

The next Working Group meeting is scheduled for 21-24 July 2009 in Tokyo, Japan (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.

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.
