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

Report on the meeting held in Boston on 15-18 October 2007

The working group continues its rapid progress towards agreement on a baseline draft standard.

The plan of the working group is to conduct a down selection process on proposals from each of the following clusters to form the baseline draft standard:

  • An in-home cluster that allows low-voltage wiring in structures to carry digital content
  • An access cluster that provides for transmission of broadband content on the medium- and low-voltage power lines that feed homes
  • A coexistence and interoperability cluster that ensures all equipment and devices used on BPL networks are compatible.

In Boston, the latest updates of the remaining proposals were presented: two in-home proposals, two access proposals, and two coexistence proposals

One round of elimination voting was then held on the in-home and access clusters. As a result, a single proposal for each of these clusters remains under consideration for the next step (see the results of voting).

The two surviving in-home and access proposals follow a similar architecture based on one unified MAC layer and the possibility to support two Physical layers, a FFT OFDM PHY and a Wavelet OFDM PHY.

The next step for both proposals is the confirmation vote. The proposals are required to achieve 75% majority approval to become part of the baseline of the standard (see the down selection process).

For the coexistence and interoperability cluster, an important change in one proposal was announced during the meeting and as a result, the working group decided to postpone the elimination vote until the next meeting. The two proposals remain candidates.

The proposals are being continuously improved and the latest updates are expected by 20 November 2007.

The next meetings are scheduled for 11-14 December 2007 in San Diego, CA, USA and 3-7 March 2008 in Fukuoka, Japan.
