Single chip combines LoRA wireless and powerline for smart grid and IoT monitoring : Page 2 of 2

May 04, 2016 // By Nick Flaherty
Semtech has developed the first chip to combine the LoRa long range wireless protocol with a powerline communications controller for smart grid, smart metering and IoT applications.

To simplify the design effort, the chip handles all the bridging and routing algorithms between the two internal modems in an internal applications processor with embedded dual image flash memory as well as support for the Wireless M-BUS protocol for sub-metering applications. It supports the G3-PLC, PRIME, P1901.2 and S-FSK standards with a programmable frequency range from 9 kHz to 490 kHz for the PLC, while the wireless modem supports the LoRa Modem, WMBUS and 802.15.4g standards with a 168 dB maximum link budget from a +14 dBm high efficiency power amplifier.

Semtech is the main silicon developer for its LoRa protocol, which is also licesned to other chip makers such  ST and ZTE.
