IEEE P1901 Draft Standard
for Broadband over Power Line Networks: Medium Access Control
and Physical Layer Specifications
Report on the meeting held
in San Diego, CA, USA, on 11 December 2007
HomePlug Powerline Alliance-Panasonic presented the latest
updates of the surviving in-home and access proposals. Significant
progress was achieved but the working group felt the specifications
were not mature enough to conduct a 75% confirmation working
group vote (see down selection
UPA presented a proposal to merge the two surviving coexistence
proposals. The elimination vote was postponed until the
next meeting, in anticipation of a voluntary merger by that
time. Two proposals remain as candidates.
The next updates of the proposals are expected by 11 February
A subgroup was formed to develop the first draft of the
process for moving from the baseline draft standard to the
IEEE Standards Sponsor ballot (post-down selection process).
The draft will be discussed at the next meeting.
meetings are scheduled for the week of 3-7 March 2008
in Fukuoka, Japan, and the week of 22-25 April 2008 in Madrid,

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
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
