开发LoRa®这一无线通信技术是为了创建机器对机器(M2M)和物联网(IoT)应用所需的低功耗广域网(LPWAN)。
LoRa®技术的主要特点：
- 远距离：>15公里/9英里范围
- 低功耗：预期电池使用寿命为5-10年
- 低成本：从终端节点传感器成本到前期基础架构投资
- 安全：采用嵌入式端到端AES-128数据加密
- 定位：无需使用GPS即可实现室内/室外跟踪
LoRaWAN®是由LoRa Alliance®制定的全球LPWAN规范，其目的是为行业内的无缝互操作实行同一套标准。LoRa技术非常适用于以下应用：
- 智慧城市
- 智能家居和智能楼宇
- 智能环境
- 智能计量
- 智能农业
- 智能工业
- 零售和物流
作为LoRa Alliance的董事会成员、赞助者以及LoRaWAN®市场的中坚力量，意法半导体提供了多种价格实惠、易于使用的设备和硬件工具来评估和开发LoRa®解决方案。
- STM32WL MCU系列是全球首款支持LoRa®通信标准的片上系统。STM32WL是完全开放的，支持复合调制，在超低功耗方面表现出色且不影响性能，是进行LPWAN和物联网开发的理想选择。
