IEEE Approves Standard Designed to Support Low-Frequency, Narrowband Power-Line Communications and Smart-Grid Applications
PISCATAWAY, N.J. --(Business Wire)--
IEEE, the world's largest professional organization dedicated to
advancing technology for humanity, today announced that it has approved
the IEEE 1901.2™ "Standard for Low-Frequency (less than 500kHz)
Narrowband Power-Line Communications for Smart-Grid Applications." The
achievement has been driven and is sponsored by the Power-Line
Communications Standards Committee of the IEEE Communications (News - Alert) Society
"The IEEE 1901.2 standard raises the bar of performance with mandatory
differential and robust coherent modulation, with added enhancements for
increased data rates greater than 300kbps," said Jim LeClare, chair of
the IEEE Low-Frequency Narrowband Power-Line Communications Working
Group. "The design potential for low-frequency, narrowband OFDM
(Orthogonal Frequency Division Multiplexing) Power-Line Communications
(PLC) has expanded past the energy industry, with designs spanning the
globe in industrial automation, transportation, street lighting, mining,
medical applications and more."
In August 2013, IEEE 1901.2 completed its first sponsor ballot, which
paved the way for its approval. Because the standard was natively
designed for the modern smart grid, it leverages techniques and recent
innovations in communications technology and the smart grid security
framework. Comprised of three foundational components-physical/medium
access (PHY/MAC) layer, coexistence and electromagnetic-compatibility
(EMC (News - Alert)) requirements-IEEE 1901.2 supports the balanced and efficient use
of the PLC channel by all classes of low-frequency and narrowband
devices. The standard defines detailed mechanisms for coexistence among
standard technologies operating in the same frequency band.
"Over a two- to three-year time frame, the IEEE 1901.2 working group has
worked very hard to bring this standard from draft form to full
approval," said Oleg Logvinov, vice chair of IEEE Low-Frequency
Narrowband Power-Line Communications Working Group and director of
special assignments, Industrial and Power Conversion Division,
STMicroelectronics (News - Alert). "I would like to extend a hearty congratulations to
the entire working group for reaching this milestone. Having this
standard widely available is paramount to the forward progress of
technologies provided by semiconductor manufacturers, meter and systems
manufacturers, software deveopers, service providers, utilities and
Designed to specify secure PLC at data rates up to 500kbps and at
transmission frequencies of less than 500kHz for applications, IEEE
1901.2 addresses low-frequency, narrowband PLC over low-voltage lines of
less than 1000V between transformer and meter, through transformer
low-voltage to medium-voltage (1000V up to 72kV) and through transformer
medium-voltage to low-voltage power lines in both urban and in
long-distance (multi-kilometer) rural communications.
