Low-Frequency Narrow-Band Power Line
Communications Working Group
IEEE P1901.2 Working Group Status Update - January 2013
During
the October 2012 IEEE P1901.2 Working Group meeting, the Working Group
voted to open a Letter Ballot to approve the current working draft
document and forward it to the Sponsor for approval for Sponsor Ballot
Group voting. The results of the Letter Ballot vote were 96% approval
rating, and 100% of the Working Group voting members returned a vote.
At the next P1901.2 Working Group meeting in January 2013, the Working
Group will work to resolve the comments associated with this Letter
Ballot, and open the Sponsor Ballot invitation. Next steps include
submission of the working draft to the Sponsor Ballot group, and
subsequent Standards Board approvals and publication.

Project Background
The project authorization request (PAR) for P1901.2, Draft Standard for
Low Frequency (less than 500 kHz) Narrow Band Power Line Communications for
Smart Grid Applications, was approved by the IEEE-SA Standards Board on
25-March-2010. The project scope is:
This
standard specifies communications for low frequency (less than 500 kHz)
narrowband power line devices via alternating current and direct
current electric power lines. This standard supports indoor and outdoor
communications over low voltage line (line between transformer and
meter, less than 1000 V), through transformer low-voltage to
medium-voltage (1000 V up to 72 kV) and through transformer
medium-voltage to low-voltage power lines in both urban and in long
distance (multi-kilometer) rural communications. The standard uses
transmission frequencies less than 500 kHz. Data rates will be scalable
to 500 kbps depending on the application requirements. This standard
addresses grid to utility meter, electric vehicle to charging station,
and within home area networking communications scenarios. Lighting and
solar panel power line communications are also potential uses of this
communications standard. This standard focuses on the balanced and
efficient use of the power line communications channel by all classes
of low frequency narrow band (LF NB) devices, defining detailed
mechanisms for coexistence between different LF NB standards developing
organizations (SDO) technologies, assuring that desired bandwidth may
be delivered. This standard assures coexistence with broadband power
line (BPL) devices by minimizing out-of-band emissions in frequencies
greater than 500 kHz. The standard addresses the necessary security
requirements that assure communication privacy and allow use for
security sensitive services. This standard defines the physical layer
and the medium access sub-layer of the data link layer, as defined by
the International Organization for Standardization (ISO) Open Systems
Interconnection (OSI) Basic Reference Model.
The
Project is sponsored by the Communications Society (ComSoc) and the
resultant standards project is entity based (one company, one vote).
