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, 3-6 February 2009
The three confirmed In-Home, Access, and Coexistence proposals
formed the baseline of the Draft Standard. Following the
confirmations, the first objective was to assemble the three
documents of almost 2,500 pages in total and merge them
into a unified and consistent single Draft Standard. As
outlined in the P1901 process, the Draft Standard is then
improved through successive rounds of commenting within
the Working Group until it is mature enough to go to IEEE-SA
At the Miami meeting, the Working Group adopted a tentative
table of contents of the Draft Standard (having 18 clauses)
and agreed upon a work plan. The tasks were allocated to
four Technical Subgroups (TSGs). TSG1 is in charge of editorial
tasks, TSG2 is in charge of the confirmed FFT and Wavelet
PHYs and MACs, TSG3 is in charge of developing the new ITU-T
G.hn Compatible PHY/MAC option, and TSG4 is in charge of
all coexistence aspects.
The TSGs held kick-off meetings and reported detailed work
plans to the Working Group at the end of the WG meeting
Report on the meeting held in
Dresden, Germany, 24-27 March 2009
Since the Miami meeting, a first version of the Draft Standard
was issued. It contains the text of the confirmed In-Home,
Access, and Coexistence proposals mapped according to the
tentative table of contents (as adopted in Miami).
TSG2, TSG3, and TSG4 held weekly teleconferences. The TSGs
have progressed in the development of unified content that
replaces the original text from the confirmed In-Home, Access,
and Coexistence proposals.
During the meeting in Dresden, the majority of the week
was dedicated to Technical Subgroup meetings. The TSGs reported
progress of their work to the Working Group on the last
TSG2 presented unified text for the first four clauses
of the Draft Standard, which the Working Group unanimously
TSG4 presented a refined Draft Standard table of contents
that details how to merge the confirmed Coexistence proposal
with the other confirmed proposals. The Working Group unanimously
approved this refined table of contents.
The TSGs will continue holding weekly teleconferences.
TSG2 will hold a face-to-face meeting during the week of
21-24 April 2009 in Orlando, FL, USA.
The next meeting is scheduled for 18-22 May 2009, Las Vegas,
NV, USA (see next meetings).
June 2005 - PAR approved
November 2005 - Adoption of the general
work flow - Formation of a sub-group to develop unified
January 2006 - Approval of the use cases - Decision to split
the requirements into three clusters: In-Home, Access and
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
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
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
