LoRaWAN 科技

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 LPWAN market,ST offers several affordable and easy-to-use sets of hardware tools dedicated to the evaluation and development of LoRa™ solutions.
Combined with the LoRaWAN™ software expansion package for STM32Cube (I-CUBE-LRWAN) which includes a set of libraries and application examples, these hardware tools are the quickest way to build LoRaWAN end-node devices:

• 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
• STM32 Discovery kit for LoRa™ and other LPWAN protocols (B-L072Z-LRWAN1) 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
