IoT technology for smart meters and lighting specialist Greenvity Communications has launched a system-on-chip (SoC) with Wideband Power Line Communication (WB PLC) technology designed to provide high speed, reliable and extended range communication for next-generation smart meter applications. The Hybrii-LB GV7013LB is designed to address slow speed, high latency and high noise interferences, difficulties that Narrowband PLC (NB PLC) technology encounters in environments such as China and India.

The GV7013LB chip integrates a microprocessor for low power management and intelligent networking that can support up to 1,000 meters per network. It can be deployed inside smart meters, concentrators and data collectors. The Hybrii-LB chip is designed and tested for industrial temperature requirements (-40 degrees C to +85 degrees C), making it suitable for industrial applications including smart meter applications.

According to Greenvity, smart meters enabled by either NB PLC or Narrowband wireless (NB RF) can be limited by slow speed, long latency and noise at low frequency bands. The company says that smart meter OEMs predict that due to the improved performance, long range capabilities and cost-effectiveness of wide band PLC, WB PLC will replace most NB PLC and NB RF solutions in the next generation of smart meters.

The GV7013LB is designed to offer high performance and robust power line connectivity with data rate over the line up to 4 Mbps, which supports demand response and real-time control to save energy in smart meter applications. 

Greenvity says that the GV7013LB can be configured to scale the upper frequency of the spectrum from 7MHz to 15MHz—an innovative and unique feature that allows Greenvity’s chip to adapt to different regulations and environments in many countries. Using OFDM technology across the 2 MHz to 12 MHz spectrum complies with requirements set by regulatory agencies in China and other Asian countries. The company says that the Hybrii-LB offers reliability and increases noise immunity in a system that enables long distance communications up to 1.5 Km. The Hybrii-LB chip integrates the proprietary relay algorithm as an option to extend range beyond 1.5Km.

“Greenvity is leading the connectivity technology for the next generation of smart meters with our patented Wideband PLC,” said Hung Nguyen, president and CEO of Greenvity. “Our GV7013LB and its smart metering software suite enables OEM customers to create and produce smart meter solutions with true demand response and real-time control over a large metering network and also helps them get to market more quickly.”

Hybrii-LB chips have been deployed in many smart meters in southern China and are scheduled to be deployed in India in the second half of 2017.
