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

Report on the meeting held in Miami, FL, USA, on 8-10 July 2008

Updated proposals for the In-Home, Access, and Coexistence clusters of requirements were presented to the working group for confirmation votes. The confirmed proposals become part of the baseline P1901 draft standard.

The confirmation vote on the Panasonic-HomePlug-HiSilicon In-Home proposal was conducted first. The proposal received 71% positive votes. The 75% majority approval required to become part of the baseline for the P1901 draft standard was not achieved, and the confirmation vote failed.

The confirmation vote on the HomePlug-Panasonic Access proposal was conducted and failed to receive the required 75% majority approval. The proposal received 55% positive votes.

The confirmation vote on the CEPCA-SiConnect-HomePlug Coexistence proposal was conducted and failed to receive the required 75% majority approval. The proposal received 58% positive votes

See the results of voting for more details.

The P1901 working group down selection process allows for a second opportunity to pass the confirmation vote before the process is reset (see the down selection process). Members were given three weeks to return comments for improvement of the proposals that failed confirmation voting.

The second round of confirmation voting for the three clusters of requirements will be held during the next meeting, scheduled for 29 Sept-2 Oct 2008 in Madrid, Spain.

The process that follows the down selection of the technical proposals is being finalized. It defines the steps for developing the first version of the Draft Standard and subsequent development until the working group decides to move it to Sponsor ballot.

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.
