LoRa® is a wireless communication technology developed to create the low-power, wide-area networks (LPWANs) required for machine-to-machine (M2M) and Internet of Things (IoT) applications.
Key features of LoRa® technology:
- Long range: >15 km / 9 mi range
- Low-power: 5-10 year expected battery lifetime
- Low-cost: from end-node sensor cost to upfront infrastructure investment
- Secure: with embedded end-to-end AES-128 encryption of data
- Geolocation: enables indoor/outdoor tracking without GPS
LoRaWAN® is a global LPWAN specification created by the LoRa Alliance® to drive a single standard for seamless interoperability across the industry. LoRa technology is ideally suited for the applications:
- Smart Cities
- Smart Home and Building
- Smart Environment
- Smart Metering
- Smart Agriculture
- Smart Industrial
- Retail and Logistics
As a board member and sponsor of the LoRa Alliance and strong player on the LoRaWAN® market, ST offers several affordable, easy-to-use devices and hardware tools to evaluate and develop LoRa® solutions.
- The STM32WL MCU series is the world’s first LoRa®-enabled System-on-Chip. The STM32WL is fully open and supports multi-modulation, making it the ideal choice for LPWAN and IoT developments with outstanding ultra-low power consumption without compromising on performance.
- The NUCLEO-WL55JC1 board for 868, 915 and 923 MHz RF bands and the NUCLEO-WL55JC2 for 433 and 470 MHz RF bands provide an affordable and flexible way for users to try out new concepts and quickly build LoRaWAN® prototypes with the STM32WL Series microcontroller, choosing from the various combinations of performance, power consumption, and features. The boards feature an STM32WL55JCI7 along with ARDUINO® Uno V3 connectivity support and ST morpho headers. They do not require any separate probe as it integrates the STLINK-V3E debugger and programmer. LoRaWAN stack is available in source code format in STM32CubeWL.
Alternatively, the following hardware tools offer also a fast and efficient way to build LoRaWAN® end-node devices when combined with the LoRaWAN® software expansion package for STM32Cube (I-CUBE-LRWAN) including source code and a set of application examples.
- The P-NUCLEO-LRWAN2 pack for 868, 915 and 923 MHz RF bands comes with a gateway and an end-node. The gateway combines an STM32F7 Nucleo board and an ARDUINO®-compatible shield with a Semtech® SX1301 transceiver. The LoRaWAN® end-node features an STM32L073 Nucleo board and an STM32L052-powered USI module, along with ST’s sensors including our LSM303AGR MEMS accelerometer/gyroscope, LIS3MDL magnetometer and LPS22HB pressure sensor, and ST's HTS221 temperature and humidity sensor.
- The P-NUCLEO-LRWAN3 pack for 433 and 470 MHz RF bands contains a gateway and an end-node. The gateway includes an STM32F7 Nucleo board which controls an ARDUINO®-compatible shield with an embedded Semtech® SX1301 transceiver. The LoRaWAN® end-node features an STM32L073 Nucleo board and an STM32L071-powered RisingHF module on an ARDUINO®-compatible shield, along with several motion and environmental sensors including the LSM6DS3 accelerometer, ST's LPS22HB pressure sensor, and our HTS221 temperature and humidity sensor.
- STM32 Discovery kit for LoRa® and other LPWAN protocols with an all-in-one open LoRa® module powered by an ultra-low-power STM32L072 32-bit microcontroller and an SX1276 RF transceiver
- STM32 LoRa® expansion board for the STM32 Nucleo (I-NUCLEO-LRWAN1) featuring a low-cost USI® LPWAN module supporting LoRa® technology
- Low-power wireless Nucleo pack (P-NUCLEO-LRWAN1) including STM32 Nucleo-64 development board and LoRa® expansion board with high-performance SX1272 FSK/OOK RF transceiver
We asked Benjamin the following questions: What is FOTA and it's benefits? How can we meet the challenge of FOTA over LoRaWAN? So LoRaWAN FOTA is really happening?
In this video Michael Andre, CEO of WIZZILAB presents their products to us, a triple stack solution for LPWAN technologies, including Sigfox, LoraWan and the Dash7 alliance which leverages many products from STMicroelectronics.
