Market Overview

Hi3911 is the first broadband carrier chip developed for centralized metering of power lines. It employs the orthogonal frequency-division multiplexing (OFDM) and noise reduction technologies and optimizes the band scope to address high power consumption and short transmission distance of BPLC. It provides a technological basis for implementing intelligent, automatic, and efficient centralized metering and ushers in the broadband carrier centralized metering era.
