Analog and mixed-signal chipmaker Semtech Corp. has introduced what it claims to be the first integrated power line communications (PLC)+RF system-on-chip with LoRa (long range) wireless RF technology device designed for smart grid, smart metering and Internet of Things (IoT) applications.

Semtech Launches Integrated PLC and LoRa Modem Targeted at the Smart Grid
04 May 2016
The EV8600 dual-modem device helps to reduce network operational costs of advance metering infrastructures (AMI) by up to 50%, Semtech says. The chip also allows for seamless LoRa gateway network deployment of IoT solutions for smart cities and industrial automation.
Semtech says by offering a PLC modem operating at 10-500KHZ and a RF modem operating in the range of 142-1050MHz, the EV8600 virtually enables 100% connectivity coverage with a single chip. By adding LoRa connectivity, the chip has a fallback mode in the event of a complete network outage caused by unforeseen events or natural disaster.
According to Reza Mirkhani, VP of Smart Grid Products at Semtech, AMI networks are already migrating to PLC+RF Dual PHY architectures to achieve close to 100% coverage. With the addition of LoRa, the chip allows for interoperability among smart things for IoT. Mirkhani says the EV8600 “helps eliminate the 1% problem in AMI networks, where the cost of reaching the 1% hard-to-reach nodes can account for as much as 50% of the entire AMI network operational cost.”
