Semtech adds LoRa RF to Wi-SUN for meter reading and industrial applications

October 07, 2014 // By Graham Prophet
Semtech is cooperating with Freescale and Nissin to develop a complete solution featuring the Freescale Kinetis MCU and Nissin Wi-SUN software stack, for the Japanese market; Semtech has announced it has joined with other members of the Wi-SUN Alliance to produce a radio frequency (RF) development platform targeting advanced metering infrastructure (AMI) and industrial applications.

The development platform includes Semtech's SX1276 Wi-SUN compliant RF transceiver that features its long-range LoRa technology, combined with a Kinetis microcontroller (MCU) from Freescale. The Wi-SUN ready software stack is provided by Nissin, a contributor member of Wi-SUN.

"As an active member of the Wi-SUN Alliance, Semtech is promoting not only its RF chips, but also the availability of a ready-to-integrate solution targeting the Japanese AMI market," says Marc Pegulu, Vice President of Marketing for Semtech's wireless sensing and timing business unit. "For the first time, a Wi-SUN ready platform, including RF transceiver, MCU and software stack is made available to industrial customers building Japan's metering infrastructure."

The Semtech SX1276, a Wi-SUN ready, LoRa-based transceiver with a 168 dbB link budget for maximum range, constitutes the wireless portion of the solution. The LoRa long-range technology, combined with the Nissin software stack, enables customers to reduce infrastructure cost and improve quality of service.

"Thanks to its low-power characteristics, on-chip analogue and security integration, as well as scalability across a wide memory footprint, the Freescale Kinetis MCU architecture is particularly suited for AMI and currently used in many metering applications," said Emmanuel Sambuis, Director for IoT & Connectivity at Freescale Microcontrollers. "When used in conjunction with Nissin software and the Semtech transceiver, Kinetis MCUs offer Freescale customers the best possible combination for performance, cost and time to market."
